Moon Rising - Book Review

A few weeks ago, first-time author Jerry Kaczmorowski emailed me and asked if I would like to review his book Moon Rising.  He told me that there was an American-built space elevator involved (as well as some other details I’ll let the reader explore) and, of course, that was enough to get me to say “Yes”.

I finished the book shortly after I started it - here is the review I put on Amazon:

This is an excellent book, especially for a first-time author.  The plot is rich and detailed and keeps the reader guessing.  The characters are believable and the action is non-stop.  Once I started reading it, I didn’t want to put it down and I believe that others who are fortunate enough to take a chance on this new author will feel the same.

As the author of the Space Elevator Blog, I’m always intrigued by a new book with a Space Elevator as the theme or the backdrop.  I’m also always worried because the authors of many of these types of books have obviously not done their homework on how a Space Elevator could be built or could work - they seem to have skipped all of their science and math classes in school.

Thankfully this book is not like that.  The author doesn’t delve deeply into Space Elevator architecture (it’s not the focus of the book), but what technical details he does write about are plausible.  What this book also does is show WHY we would want to build a Space Elevator and then presents a scenario as to HOW a Space Elevator might actually come about.  I don’t want to spoil the plot for new readers, but suffice it to say that, in this book, the world does NOT come together, sing “Kumbaya” and then build a Space Elevator for the advancement of all mankind.

I do have a couple of nits; the characters seem a bit one-dimensional at times and the villains are the “usual suspects”.  Nevertheless, adding everything together, I give this book 5 well-deserved stars and I look forward to this author’s next effort.

The author is going to be at the upcoming ISEC Space Elevator Conference (you ARE coming, yes?) and I look forward to meeting him.

And, buy the book - you’ll enjoy reading it!

LEGO Space Elevators and Tall Structures

At this URL, there are two YouTube videos.  The first shows a “space elevator” being constructed by a LEGO Mindstorm kit.  Slow, clunky, but kind of cool.

The second video discusses tall structures built by humans and ends in speculation about building a space elevator.  Nice to see that the author/narrator (Vsauce) seems to have his scientific facts correct.  Two cool moments in the 10+ minute-long video…  The first is at about 3:12 and shows one of those very tall radio masts snapping in half and collapsing - always neat to see things breaking!  And the second cool moment, at least for me, occurs around the 5:30 mark.   Vsauce discusses how you can actually see two sunsets (or sunrises, if you’re so inclined) in the same day by physically manipulating your body at the moment of sunset (or sunrise).  To emphasize the point of your height above ground being a factor as to when you see a sunset, Vsauce mentions that a ruling by the Dubai Islamic Affairs Department actually had to be made for Muslim residents of the Burj Khalifa (the world’s tallest building) in Dubai as to when the sun set.  This is important for the Islamic holy month of Ramadan - you cannot break your fast until “official” sundown and, for residents of the Burj Khalifa, sundown is declared at one ‘official’ time for residents from floors 1-79 and at another ‘official’ (and later) time for residents of floors 80 and up.

Yes, they take such things very seriously in the Middle East (and, I assume, wherever Muslims live in great numbers).  I lived in Saudi Arabia for eight years and, during the times I was in-Kingdom for Ramadan (Eid Al-Fitr) and/or Islamic New Years (Eid al-Adha), I was greatly intrigued by the attention that was paid to this.  The newspapers would project the actual clock times these events would begin.  For Ramadan, as noted above, it was when the sun set on a certain day.  For New Years, it was the first sighting of the new crescent moon during the proper lunar cycle.  When this happened for New Years (in Jeddah, at least) a ceremonial cannon would be fired and the person who first sighted the new moon would win a prize.  There is a story (probably apocryphal) about someone who happened to walk in front of the ceremonial cannon just as it was set off and was blown to bits.  No, I don’t believe it either…

As an aside, the Muslim calendar is 12 months long, as is the Gregorian one, but it is strictly governed by lunar cycles.  This means each month is about 29.5 days long with an Islamic year being about 354 days long.  So, the months (and the holidays) gradually cycle ‘backward’ through the Gregorian calendar.  When I first arrived in Saudi Arabia, in 1979, the Islamic New Year (Eid Al-Adha) was in late November.  In the 35 years since (jeez, has it really been that long?), the New Year has gradually moved backward through the Gregorian calendar (for example, in 1995, the Islamic New Year was at the end of May).  Fun facts with dates!

Anyway, both videos are, IMHO, fun to watch.

And, in keeping with the theme of this post, this is a very short, very awesome video…

Results from the Technion Space Elevator Competition

Sometimes the simplest ideas are the best.  A couple of weeks ago, the Technion Institute in Israel held a Space Elevator competition (I’ve previously posted about this competition here and here).  The winner used the inner workings of an electric screwdriver to power his Climber.

Details can be found here.  Money quote from the winner: “The idea of basing the engine on an electric screwdriver we borrowed from the world of manufacturing plastic pipes using plastic extrusion, in which raw plastic material is melted and formed into a continuous profile,” said Atzili. “In short, it’s an idea that came to me originating from my experiences working in the plastics industry.

Congratulations to Technion and to the winners!

ISEC June, 2014 eNewsletter released

The latest ISEC eNewsletter is hot off the presses and can be found here.  It’s a shorter eNewsletter than usual as ISEC efforts are now focused on the upcoming Space Elevator Conference (less than two months away - you ARE coming, aren’t you?).

And, about the upcoming conference, there have been a record number of papers/presentations submitted so I think it’s safe to say that interest is running very high.

This is also a good time to remind everyone that the Early Bird Registration prices for the conference end on Monday, June 30th, so don’t delay.

See you there!

Video coverage of the Space Elevator Competition in Israel

In my previous post, I had written about a new Space Elevator competition in Israel and that the originator of the modern-day concept of the space elevator, Russian Engineer Yuri Artsutanov, would be there as a judge.  While I can’t find any results posted as of yet, I did hear from Eugene Schlusser, Yuri’s friend (and unofficial translator), who accompanied Yuri to the 2010 ISEC Space Elevator conference.  Eugene lets me know that Yuri did indeed make it to the competition and did act as a judge.  And, better yet, there was coverage of this in Russia and a YouTube video has been made of it (hint: it helps if you speak Russian and/or Hebrew :).

.
Yuri appears at two different times in the video; around the 53 second mark and again at the 1:05 mark.

I’m still hopeful of getting some pictures from the competition which I will, of course, post here.

This competition reminds me so much of the early days of the NASA/Spaceward Space Elevator Games; Climbers climbing a racetrack held aloft by a crane, students frantically working on their equipment, etc.  It brings back some great memories.

Thank you Eugene!

Yuri Artsutanov to judge upcoming Space Elevator competition in Israel

This is cool.  The father of the modern-day concept of the space elevator (and a guest at the 2010 ISEC Space Elevator Conference) Yuri Artsutanov, will be one of the judges at a Space Elevator contest being held next Wednesday, June 18th, in Israel.

This year’s challenge at the Technion – Israel Institute of Technology’s 12th annual Technobrain competition is to build a “space elevator” — a device capable of climbing in a nearly vertical manner (at an 80 degree angle to the ground), to a height of 25 meters.

More details can be found here and here and there is also a posting on the Technion Facebook page.  The official posting from the Technion website can be found here.

I’ve reached out to both Yuri and the Technion institute for more details.

Dr. Bryan Laubscher will be on The Space Show on Sunday

Dr. Bryan Laubscher, long-time space elevator enthusiast and principal owner of Odysseus Technologies, Inc., a carbon-nanotube startup company, will appear on Dr. David Livingston’s The Space Show this coming Sunday, June 8th, from 12 noon to 1:30pm, Pacific Daylight time.  He will be there to discuss the latest developments in the Space Elevator field along with carbon nanotubes and nanotechnology in general.  Dr. Laubscher’s bio:

Dr. Laubscher is a PhD in Physics with a concentration in Astrophysics. After a career as a project leader at Los Alamos National Laboratory that included research and development of astronomy projects, space missions, satellite instrumentation, optics, novel electrodynamic detection techniques, high power lasers, and classified projects Bryan became interested in the Space Elevator.  Bryan’s current Space Elevator activities include being the General Chairman for the annual Space Elevator Conference held at the Microsoft Conference Center in Redmond, WA.  Pursuing the R&D of the Space Elevator has led him to start Odysseus Technologies, LLC a small company based in Washington state with the goal of developing high strength carbon nanotube materials. In August 2010, Odysseus Technologies competed in the NASA Centennial Strong Tether Challenge. Although the tether was not strong enough to win prize money, it was strong enough to beat the other two teams. Odysseus Technologies, LLC is planning to compete in the 2011 challenge.  Bryan now lives in Olympia, WA with his wife Carla.

Click here to see how to listen in to the show and ask Dr. Laubscher a question.

There was another $2 Million targeted towards Carbon Nanotube Research…

Occasionally, FeedDemon provides me with old articles that are very interesting.  Case in point…

Many readers will remember the Space Elevator Games, the 5 year partnership between NASA and The Spaceward Foundation, to further research and development in the fields of power-beaming and strong tethers.  The Power-Beaming games were a spectacular success, resulting in several years of exciting and photogenic competition and culminating in the winning of $900,000 by the good folks at LaserMotive.  The Strong Tether challenge was NOT a success however.  Even the promise of $2 Million in prize money provided by NASA failed to produce any competitors with entries approaching the strength of conventional materials, let alone surpassing them.  Those of us like myself who were involved in those games (and then tried, unsuccessfully to get them restarted under the auspices of ISEC) spent a lot of time theorizing and supposing why this was so.  I think at the end of the day, it was just a much tougher nut than anyone had initially thought.

An article which just popped up in my FeedDemon reader showed that another approach was taken by the sporting goods company Jas. D. Easton, Inc.  In 2009, the same year that LaserMotive won their prize, Jas. D. Easton awarded $2 Million (there’s that number again) to the UCLA Henry Samueli School of Engineering and Applied Science to fund research on advanced carbon materials for sports equipment and aerospace applications.  One of my arguments to support The Space Elevator Games Strong Tether Competition to skeptics was that even if you don’t think a Space Elevator is feasible or a good idea, there certainly would be a myriad of applications for a super-strong material such as carbon nanotubes promise to be - it would be a true game-changer in every sense of the word.

I know that UCLA continues to be a leader in CNT research and a professor from UCLA has presented at the University of Cincinnati’s CNT workshop.  Alas, it doesn’t appear that they have come up with anything revolutionary yet but hope springs eternal…

GoogleX and the Space Elevator

An article that has been making the rounds recently seems to confirm that GoogleX, once upon a time, was interested in building a Space Elevator.  This story has been reported in several outlets but they all seem to come from this story at Fast Company.

Money quote from the article:  “The [GoogleX] team knew the cable would have to be exceptionally strong– ‘at least a hundred times stronger than the strongest steel that we have,’ by ­Piponi’s calculations. He found one material that could do this: carbon nanotubes. But no one has manufactured a perfectly formed carbon nanotube strand longer than a meter.”

Yes, indeedy, that is the stumbling block.  If someone is truly interested in getting closer to the day when a Space Elevator could be built, I would recommend that they invest in Materials Science research; carbon nanotubes, boron-nitride nanotubes, carbyne, it doesn’t matter which one, just as long as the goal is stronger materials.

Many months ago, I contacted Astro Teller, the head of GoogleX, to see if they would be interested in sponsoring a rebirth of the Strong Tether Competition.  I thought their (at the time) rumored interest in the Space Elevator coupled with their deep pockets would be a natural fit.  Sadly they were not interested.  When this article surfaced, I contacted Mr. Teller again and he confirmed that GoogleX is not currently working on this project, sigh.

So, it’s nice to know that they were interested, once upon a time, but we will need to continue to look elsewhere for the breakthough needed to make this project a reality…

The Space Elevator Blog celebrates 8 years!

Yes, today this blog celebrates its 8th anniversary - it’s hard to believe that I’ve been doing this for such a long time…

Much has happened in the Space Elevator field since I first began my missives.  In no particular order they are:

The Space Elevator Games - this joint venture between NASA and the Spaceward Foundation created lots of interest in the power-beaming and strong-tether technologies over its many year run.  Games were held in California (Mountain View and Mojave), New Mexico and Utah and produced a winner (Lasermotive) that took home $900,000.  It’s unfortunate that NASA didn’t renew the contract, but they have other ‘fish to fry’ these days. However, it’s good to know that there are still organizations and groups trying to push the boundary of power-beaming.  For example, the Kansas City Space Pirates recently set an unofficial record for beam-powered flight.

The birth of the International Space Elevator Consortium (ISEC).  This organization began in 2008 and, after a rough first year, has found its way.  I was privileged to be its President for four years and it is now in the capable hands of Dr. Peter Swan.  This organization has taken up sponsorship of the American Space Elevator Conference, produces year-long studies on various aspects of Space Elevator Technology and also CLIMB, the Space Elevator Journal.  Recently, ISEC created the Space Elevator Research and History Committees to further knowledge in this field.  And hey, lets not forget the posters ISEC creates too…

The birth of the Japan Space Elevator Association (JSEA).  This very active group holds a conference every year and hosts multiple competitions too.  They have an active website and lots of members and are group of very good, committed people.

The Space Elevator Conferences.  The American ones were originally hosted by the SESI organization and have now, as noted in a previous item, been taken over by ISEC.  During the past few conferences, we’ve had luminaries such as Yuri Artsutanov and Jerome Pearson attend and give Keynote speeches and this year’s conference will be very exciting too, I’m sure.  JSEA also hosts conferences in Japan each year and EuroSpaceward (apparently not active anymore, unfortunately) has hosted a few conferences in Europe where Space Elevator Technology and Research has played a central role.

The International Academy of Astronautics released a report about Space Elevators (An Assessment of the Technological Feasibility and the Way Forward), the first comprehensive study of Space Elevators since Brad Edwards and Eric Westling’s seminal publication in 2002.  This report has been just recently published and has received a lot of Press coverage.

We’ve seen the growth and demise and then subsequent rebirth of LiftPort.  They are now concentrating their efforts on building a Lunar space elevator.  They were able to host a very successful Kickstarter campaign and raised a lot of money for their efforts.

While the Space Elevator is a familiar concept in Japan (Gundam rocks!), publicity about this enterprise is growing in the western world too.   There have been articles published about the Space Elevator in such world-wide publications as the National Geographic Magazine (both online and in print) and a Google Search on “Space Elevator” will now turn up hundreds and hundreds of hits of articles about this concept.  Also, several fictional and non-fictional books about the Space Elevator (or with the Space Elevator as a backdrop) have been published.  The idea of a Space Elevator is no longer a strange concept and I’m hopeful that this blog has had some small part to play in that.

There have been many other developments in the Space Elevator field over this past eight years, too numerous to list here.  I’ve highlighted major ones (IMHO) in my previous anniversary blogs:  Year 1, Year 2, Year 3, Year 4, Year 5 and Year 6.  No posting, sadly, for Year 7.

While all of this is good and exciting, we continue to wait for science & engineering to come up with the material strong enough to construct an earth-based Space Elevator tether.  Research in the Carbon Nanotube tensile-strength field has not made the progress that many of us had hoped for by now, but on the grand scale of things, we’re still in the ‘early innings’ of this project.  And research is now proceeding with a second material theoretically strong enough to build an earth-based Space Elevator tether from, Boron Nitride nanotubes.  Options are good things!

My faithful readers over the past several years have noted, I’m sure, this blog’s change in focus from “all-things Space Elevator” to “all-things ISEC”.  This wasn’t deliberate, but was rather a side-effect of my being president of that organization for four years.  Now that I’m no longer president (but I’m still very much involved as a Director and being in charge of publicity), the focus of this blog is returning to “all-things Space Elevator”.

So, thank you for reading and onward and upward!

A Lunar Space Elevator

As many people who follow developments in the Space Elevator ‘arena’ are aware, LiftPort has turned its attention to developing a Lunar Space Elevator.  Leonard David, SPACE.com’s “Space Insider Columnist’ recently posted a story on the current status of this project.  In this article (which includes a link to a video created by LiftPort), he interviews Jerome Pearson, the American co-inventor of the modern-day concept of the Space Elevator (and the first one, to my knowledge, that seriously discussed a Lunar Space Elevator) and LiftPort’s Michael Laine.

It’s a very good article, well worth the read…

Auroras - a Space Elevator love story?

I received an email from Mr. Niles Heckman, letting me know about Auroras, a new sci-fi short film that he and his 3-person crew are creating, a”story about love, separation, and having to say goodbye.”

Niles tells me that it is “heavily influenced by Japanese anime” and is “an unconventional story about two women in love, with the backdrop of one leaving on a space elevator flight.”

Niles and his team have a Kickstarter campaign going on until the end of this month to fund the production of this film and, as of the writing of this blog post, they have raised about $8,600 towards their goal of $10,000 - almost there!

At the Kickstarter site, you can view the Project poster and the film Trailer - let’s hope this project comes to fruition!

IAA concludes Space Elevators Seem Feasible

The International Academy of Astronautics has just published its multi-year study about the Space Elevator (I first mentioned this study here).  It’s conclusion was “Space Elevators Seem Feasible” and that’s, of course, good news, to all of us who are supportive of the concept.  From the Press Release:

                 “Academy Concludes Space Elevators Seem Feasible”

The International Academy of Astronautics just approved this conclusion when it published the study report entitled: “Space Elevators: An Assessment of the Technological Feasibility and the Way Forward.”  The report addresses the simple and complex issues that have been identified through the development of space elevator concepts over the last decade.  It begins with a summary of ideas in Edwards’ and Westling’s book “The Space Elevator” (2003).  Out of these beginnings has risen a worldwide cadre focused upon their areas of expertise as applied to space elevator development and operational infrastructure.  The report answers some basic questions about the feasibility of a space elevator infrastructure.  A preview of the main questions and answers shows the depth and breadth of this cosmic study.

  • Why a Space Elevator?
  • Can it be Done?
  • How would all the elements fit together to create a system of systems?
  • What are the technical feasibilities of each major space elevator element?

This study benefited from review and comments by numerous members of the Academy, as well as the International Space Elevator Consortium.  The study could not have been completed to this level of detail without the timely and invaluable efforts of a diverse collection of experts from around the world who contributed not only their time and knowledge, but also provided material as well as their technical expertise for the study.  There were 41 authors and five editors.  The sponsors of this study report are:  International Academy of Astronautics and the Heinlein Foundation Trust.  To order a copy visit:  www.virginiaedition.com or call (713) 861-3600.  The prices are $29.95 for hardcopy and $9.95 for electronic version.

As noted in the press release, visit The Virginia Edition to purchase the hardcopy version or Amazon to purchase the Kindle eVersion.

Historian wanted!

The International Space Elevator Consortium (ISEC) has formed a History Committee to document the invention of the concept of the Space Elevator and the ever-increasing research and design which is taking place relating to this idea.  Dr. Peter Swan, the President of ISEC, puts it this way:

“We are at a point in human history where there is activity to move off planet.  As most of the world is limited by cost to orbit, we in the space elevator community believe we can make a difference in the future.  However, as we go forward, we should also look back and record the progress that has occurred in the space elevator community.  No one else will, until much later; so, we must step up and record our own history now.”

An initial team has already been formed and an aggressive agenda has been set, but Dr. Swan is looking for someone to head up the effort.  The first Conference call of the History Committee is set to occur next Tuesday, November 12th.  If you are interested in joining the team and/or heading up the effort, please contact Dr. Swan at pete.swan [at] isec.org.

EUSPEC 2012 Revisited

One year ago, the 2012 European Space Elevator Challenge (EUSPEC) was held in Germany, at TUM Campus Garching.  A “highlights” video was created, which the EUSPEC team posted on its website.  They recently re-announced it and it makes fine/fun viewing.

You can view it here (Post by European Space Elevator Challenge (EUSPEC)) on Facebook.

The organizers of the competition have this to say about it:

 It has now been almost exactly one year since the last European Space Elevator Challenge. Take a trip down memory lane with this little video which was so far buried on our website.

We had a lot of fun during the event even though it was freezing cold at the time. In contrast, we had almost 20 degrees two days ago! Weather can be unpredictable…

We are hoping to bring back EUSPEC for 2014 or 2015. Stay tuned for any news on this site!

Looking forward to it!

KCSP writes about their success

I received this email today from Brian Turner, captain of the Kansas City Space Pirates.  It was sent out to all of their supporters:

We successfully beat the Laser Powered flight endurance record by double. Our flight time was 25 hours, 0 Minutes and 35 seconds. This was done at the VOX theater in Kansas City Kansas. We used a highly modified AR-Drone Quadcopter. We did this with 500 watts of laser power and non-exotic photovoltaic cells. Our total systems hardware costs were less than $30,000. I estimate this is well less than 1/3 of the 2009 record. Much of the hardware would cost even less if purchased today. This shows the exponential increase in human technological abilities is alive and well and that commercial laser powered flight applications are only a few years away. We can look forward to flying cell towers, autonomous shark patrols and countless other applications that only become practical with beam powered flight.

Achieving the record was not without drama. The planed for 48 hours got trimmed back to 24. We continued to 25 so we could double the previous record. Turns out that human endurance plays a role as we became tired human mistakes became a prominent concern. The lasers themselves worked flawlessly. The optics needed adjustment at the start. The quadcopter behaved like the finicky result of hacking a toy for purposes well beyond those it’s creators ever imagined. The Kansas City Star article covered all this well with this article.

We are on the cover of the online version of the paper today. We also have 3 of the top photos of the day.

We are in the Monday print version.

Thanks to all our supporters and sponsors. We would not be here without you.

KCSP succeeds in their record attempt

Over the past 25 hours, the Kansas City Space Pirates have been continuously flying a quadcopter, powered solely by laser beam.  At about 4:11am this morning, they passed the LaserMotive unofficial record time of 12 hours and 27 minutes.  Once they got the new record time, their goals shifted to double the previous record, or about 24 hours and 54 minutes.  They then slightly modified this goal to run a full 25 hours - and succeeded!

It was a very boring event, as you might imagine - watching a quadcopter hover a few feet above a target mounted on a table.  Very boring that is until about 9 hours into the record flight.  I had just tuned back in and noticed that the uStream feed was down (they DVR’d the entire run, but also broadcast it live on uStream so that people could watch in real time while it was happening).  I called Brian Turner, captain of the Space Pirates who, unbeknownst to me was taking a quick nap.  I apologized for waking him and he went to see what was wrong.  Once he fixed the problem (the cable modem for their internet feed to uStream had to be reset), he decided to sit with the crew and watch what was going on.  It’s a good thing he did because at about 9 hours and 10 minutes, a random air-current knocked the quadcopter off its target.  It started searching, moving in wider and wider swings, sending out messages about “Target Lost” and, more ominously, “Battery Low”.  Brian quickly grabbed the manual controls and brought the quadcopter back over the target.  Things settled down and the rest of the run was fairly uneventful.  I’m glad I woke Brian up!

No one officially judges or keeps tracks of records like these (their was no representative from Guinness at the original LaserMotive record flight or at this one), so the records are unofficial.  But they’re real nonetheless.  Having an aircraft continuously fly, non-tethered, for 12 hours as LaserMotive did or 25 hours as KCSP has just succeeded in doing, is very impressive and shows how reliable this type of technology can be.

KansasCity.com, the online version of the Kansas City Star, just published a story about this - a very nice summary of the entire event.

Congratulations KCSP - now let’s see how long this record stands!

(The photo thumbnail is a snapshot of the uStream presentation and you can click on it to see a larger version.  The video in the top left-hand corner is from above and a bit behind the quadcopter - you can see it hovering over the target on the table.  The video in the top right-hand corner is from in front of and slighly below the quadcopter.  You can clearly see the overlapping laser beams (there were five, I think) on the photo cells and the shadow on the target board behind the quadcopter.  The video in the lower left-hand corner shows the 90 foot distance from the lasers to the quadcopter.  The timer in the lower right-hand corner ran continuously.  This snapshot was taken just a couple of minutes before the end of the run, just when they had doubled the previous time.  Once it got to its first 24 hours, it recycled to zero, so the timer is actually showing 24 hours, 56 minutes and 55 seconds).

If at first you don’t succeed…

The Kansas City Space Pirates are now making their fourth attempt to break the unofficial power-beaming record set by LaserMotive.  Brian Turner, captain of the Space Pirates, gives us this update:

  • Recap. We have flown 3 previous times. 1 hr, 2 hrs, 5 hrs.
  • First run failed because the laser aim was out of adjustment.
  • Second run failed when drone lost track of it’s bottom target and drifted into the wall causing crash.
  • Third run failed when we moved our broadcast system and interfered with the Drone comms.

They’ve also had some “environment” issues (had to partially open some shades to create better airflow) and they think that the simple act of people walking around was causing an issue.  They’ve pretty much stopped that now and things are very stable.

As of this blog post, they are about 3 hours into run #4 and, if all goes well, they hope to eclipse the old mark of 12 hours and 27 minutes about 4:12am, Sunday morning, CST.

Looks like we’re underway…

Not a lot of commentary from the organizers, so I can’t be sure, but it looks like the attempt to break an unofficial power-beaming record is underway.

Going for the record…

The Kansas City Space Pirates are going to be going for an unofficial record this coming weekend, the record set by LaserMotive Technologies in late October of 2010.  What LaserMotive did then was make a quadrocopter (an AscTec Pelican) fly continuously for 12 hours and 27 minutes. powered solely by laser beam.  A video of that flight can be found on the LaserMotive website.

Brian Turner, captain of the Kansas City Space Pirates writes the following:

All is set for this weekends record attempt. You can tune in live and check it out at: http://www.ustream.tv/channel/brianturner

Launch is set for Friday 6:30 PM CDT We plan to fly till 6:30 pm Sunday. The previous record of 12 hours 27 minutes should be passed at about 7 am Saturday.

Helping me with this record are Chad, Don, Frank, Quinn, Ravi, and Joe. Ustream has a chat function that we will be active on during the flight.

If you visit the ustream channel, you can see a couple of videos from previous tests run by the Space Pirates.

Ah, this brings back memories of the “glory years” of power-beaming competitions, culminating in the victorious run by LaserMotive.

I’ll be posting further news as I receive it - good luck to Brian and his team!

Science writer David Appell writes about Space Elevators and the recent Space Elevator Conference

Science writer David Appell attended all 3 days of the recent Space Elevator Conference and, in the current issue of Pacific Standard, he writes about the Conference and what he learned there.

It’s a very good overview article and accurately summarizes where things are in this effort at the moment.  He also talks about the exciting LiftPort effort to build a Space Elevator on the moon.

Thanks David!

2013 Space Elevator Conference - Day 3

The 2013 Space Elevator Conference wrapped up today with another full schedule.  Attendees got one last “fill” of informative and interesting presentations as well as a chance to participate in 2 more workshops.

The first activity of the day was an informal polling of the audience as to this question: What would you do with a space elevator?  The answers ranged from the serious (colonize the Moon & Mars, send radioactive waste to the sun or to the moon for storage) to the whimsical (bring old cars up the tether and drop them from several kilometers up and then watch them burn up in the atmosphere!).  This activity happens at every Conference and it’s always interesting to see what new ideas arise.  The exercise does serve a serious purpose, helping to identify potential customers for a functioning Space Elevator.

The first presentation of the day was Electric Currents on the Space Elevator and was given by Dennis Wright.  He addressed one of the objections that is commonly raised against the space elevator, the concern of electrical currents which might be induced in the Space Elevator by various space-related factors and the fact that a Space Elevator is, in fact, a 100km long object that rotates along with the earth.  There are many unknowns about a structure like this, but Mr. Wright took the “knowns”, added some reasonable guesses for the “unknowns”, and came up with some preliminary conclusions.  In general, it doesn’t look like these induced currents are much of a problem (big caveat about the unknowns of course), but he did point out a potential electrical danger from broken strands of the elevator.  It was a very interesting talk and it’s clear that this type of investigation needs to be ongoing.

This talk was followed by multiple “Shotgun Science Sessions”.  This is a fixture of Space Elevator conferences now, a series of “5 minute”, “not ready for prime time” presentations where people can stand up and propose practically anything they want.  The audience then has a chance to ask questions and, perhaps, shoot the idea down.  These sessions ranged from being a Sci-Fi author, to how to dig regolith on the moon, to using a Space Elevator to send radioactive waste to the sun to everything in between.  These are lots of fun and have the added benefit of really getting the audience involved.  Presenters also know that they can speak without fear of being ridiculed - every idea is treated respectfully (even when it gets shot down!).

Following lunch, we then had the final two Workshops of the Conference.  This first was conducted by Dr. Bryan Laubscher and was entitled Balloon Experiments Workshop.  Dr. Laubscher wants to set up a competition for school age kids (middle school through College) that would, loosely defined, have teams who build Climbers that ascend/descend tethers that hang from balloons.  Teams would be judged on the kind of data they could collect, robustness, and several other suggestions made from the audience.  I hope Bryan gets this off the ground (pun intended) - it sounds like a lot of fun!

The last workshop was the Space Elevator Operations Workshop and was orchestrated by Skip Penny.  Skip was the chief author of the recently published ISEC study on Space Elevator operations. Skip reviewed the report and its updates and then gave a brief talk on challenges / opportunities in operating a Space Elevator.  The group then broke up into several sub-groups, each tasked with looking at a different problem or challenge in Space Elevator operations.  It was interesting, but not really unexpected, that the sub-groups came up with more questions than answers…

The day wound up with an open conversation between the audience and the Conference organizers as to possible improvement for future events & conferences.  There were lots of good ideas presented as to advertising, affiliations and workshops and I’m sure the conference organizers will use this input to make next year’s conference even better.

So, the 2013 Space Elevator Conference has come to a close - and it was a wonderful 3 days.  Once again I learned a lot, met a lot of interesting and fun people and had my enthusiasm for the Space Elevator project brought to new heights (once again, pun intended).

See you here next year!

2013 Space Elevator Conference - Day 2

Well, the second day of this year’s Space Elevator Conference has come and gone.  As with Day 1, it was filled with very interesting presentations and a useful and thought-provoking workshop.  And, as happens at these conferences, people have had a chance to get to know each other now and the personal interaction is increasing greatly - there are a lot of really interesting people here!

Today was very full too - beginning with a presentation from Bryan Laubscher, the CEO of Odysseus Technologies, Inc. (OTI).  OTI is in the business of creating strong CNT tethers.  It has had entries in a couple of the NASA/Spaceward Strong Tether challenges and has been trying some very novel approaches in the search for macro-level strong tethers (full disclosure: I am an investor in OTI).  Bryan’s presentation was on OTI’s PANG (Proximate Atom Nanotube Growth) Technology, an attempt to counter the phenomena that slow and halt the growth of CNTs when grown using chemical vapor deposition (CVD) techniques.  As we all know, creating a tether that is strong enough remains the single most difficult problem to deal with in building an earth-based space elevator.  As an investor in OTI and as a space elevator enthusiast, I hope that PANG bears fruit!

The next presentation was an overview of the just-completed International Academy of Astronautics (IAA) study on the Space Elevator.  In the study, entitled Space Elevators: an Assessment of the Technological Feasibility and the Way Forward, the 40 contributing authors (some from ISEC) and five editors expand on innovative ideas that increase the probability of a Space Elevator being built.  This study is to be released near the end of this year and its release will, of course, be announced on the blog.

The last presentation of the morning was on the 2013-2014 ISEC Theme.  Each year (and we’re talking about an “ISEC year” here - beginning and ending with the Space Elevator Conference), ISEC chooses a Theme to focus many of its activities around.  Past year’s themes include the study of Space Debris, the study of a possible Operations scenario for an earth-based elevator and the just-completed year’s theme, Tether Climbers.  For the first two Themes, ISEC prepared and published an in-depth report.  This same process is occurring for the just-completed year’s Theme, Tether Climbers.  The Theme that ISEC chose for the 2013-2014 ISEC year is Architecture and Roadmaps.  Dr. Peter Swan, the new President of ISEC and Michael Fitzgerald, a newcomer to ISEC, gave the presentation.   The 2013-2014 ISEC study will focus on comparing and contrasting the multiple approaches to  building and operating a Space Elevator that have been proposed over the past 10 or so years.  A preliminary report will be presented at next year’s Space Elevator conference with the final report to be produced and distributed some months after that.

After a lunch break, the entire afternoon session was devoted to the Lunar Elevator workshop, orchestrated by LiftPort president, Michael Laine.  Long time space elevator fans know that Michael has been involved in the Space Elevator effort since the early days.  Michael grew frustrated with the slow pace of carbon nanotube (CNT) development and decided to try and find something to kick-start the development of a Space Elevator.  The project he chose was to build a Space Elevator on the moon, something that can theoretically done with materials available today.  Michael and Liftport and the many allies & partners he’s gathered are making a serious attempt at this - something that all of us in the space elevator community should enthusiastically support. Michael and several of his key partners gave short presentations on the advantages of a Lunar Space Elevator and how something like this should be built.  It was serendipitous that Jerome Pearson was at this conference - after all, he was THE inventor of the idea of a Lunar Space Elevator and I don’t think anything would please him more than to see this idea actually get off the ground (to coin a phrase)…

If you want to find out anything more about this project, check out the LiftPort website.  Many of you might also know that simultaneously with last year’s Space Elevator Conference, Michael and Liftport raised money on Kickstarter to jump-start this project.  His initial goal was to raise $8,000.  By the time it was all said and done, he had raised well over $100,000 - the power of group funding!

After the workshop, it was time to watch the finals of the Space Elevator robotic competition that was being held at the Museum of Flight.  This is always a fun time, watching teams of children (up to and including high-school age) build robotic climbers to compete with one another for prizes donated by one of the Space Elevator Conference’s sponsors, Microsoft.  Jerome Pearson was asked, and graciously agreed, to announce the winners and hand out the prizes.  Many people in the audience, including competitors and their parents, were thrilled to be able to meet Jerome and get their picture taken with him.  It has been absolutely wonderful to have him at this year’s conference.

The day wound up with the annual Space Elevator Conference banquet.  This year it was held at the Charles Simonyi Space Gallery.  This Gallery hosts the Space Shuttle Trainer that was built to train the various Shuttle crews.  Every one of the crews from all 135 Shuttle missions were trained on this trainer.  It’s hard to imagine how big it is until you actually walk inside it.  While the front section was the subject of a guided tour (which I was unable to make), the back section, including the cargo bay, can be freely entered.  It’s an awesome sight.  And above the Trainer was a 50%-sized model of the Hubble Telescope hanging from the ceiling.  The Gallery is über-cool and it made it hard to concentrate on the excellent dinner we enjoyed.

So ends Day 2 - I eagerly await Day 3!

2013 Space Elevator Conference - Day 1

Today, Friday - August 23rd, was the first day of this year’s annual Space Elevator Conference, hosted by ISEC.  For the second year in a row, it is being held at Seattle’s Museum of Flight, a truly outstanding venue for conferences such as ours.

We had a very full first day - several presentations, including a Keynote speech by one of the co-founders of the Space Elevator, American engineer Jerome Pearson, and a Tether-Climber workshop.

The day started out with a welcoming speech from the ISEC Conferences Chair David Horn, followed by a Space Elevator System Overview given by Dr. Peter Swan.  This was followed by a short ISEC Officers report (more about this in another post).

Then Jerome Pearson gave the Keynote address - Sir Arthur Clarke and the Space Elevator.  Jerome talked about his long relationship with Sir Arthur, how they met, how they worked together on projects, including Sir Arthur’s brilliant book The Fountains of Paradise and many other related topics.  His anecdotes about their relationship and other stories from Sir Arthur’s life were truly interesting.  Anyone who is a fan of the Space Elevator and/or Sir Arthur would see this speech as a “must-view”.  I video-taped it and, when I get home and can punch up the audio to a respectable level, I’ll post it on the ISEC YouTube channel for all to see.  Mr. Pearson has a brilliant and agile mind and it was very enjoyable to get to meet him again.  He is currently doing work with NASA (his EDDE project) to help remove Space Debris - a necessary and long-overdue task.

After a short break, Dr. Martin Lades gave a remote presentation (he is in Germany where he resides) on Climber-Tether Interfaces for a Space Elevator.  I think most people, when they think about the problem at all, just assume that you can equip a Tether-Climber with some sort of pinch-roller mechanism to propel the Climber up/down the tether.  Alas, it’s not so simple - the devil is always in the details.  The profile of the tether is very small and it is believed that a carbon nanotube-based tether will have a very low friction co-efficient.  Solving this with brute-force (i.e. having the rollers pinch the ribbon very tightly) introduce their own problems.  Dr. Lades discussed the various options which might be used to solve this problem.

Mechanical Engineer Larry Bartoszek (making his first appearance at a Space Elevator Conference in 9 years) then talked about the difficulty of Getting the Mass of the First Construction Climber under 900kg (something postulated in Dr. Edwards book).  The problem appeared difficult, if not impossible to solve 9 years ago, and little has changed today.  If a way is not found to solve this problem, then it may not be possible to have a series of construction Climbers “build up” the tether as originally envisioned - another solution will need to be found.  As with Dr. Lades presentation, Mr. Bartoszek showed us that the devil is in the details…

After lunch, Dr. Bryan Laubscher gave a presentation on various methods that might be used in Powering Space Elevator Climbers and the status / likelihood of each.  This was followed by Dr. John Knapman’s presentation on the First 40kms Danger and Approach.  Both presentations gave the audience an opportunity to further their understanding of how a Space Elevator might actually be constructed and operated.

Following these presentations and a break, the first workshop of the Conference then took place, this on Tether Climbers.  I gave a short intro and description of a possible “hybrid” climber (using a combination of conventional, laser and solar power) and this was followed by Dr. Knapman presenting the possibility of thinking of how to power climbers in terms of “Constant Power” rather than “Constant Speed” and the tradeoffs that would result.  Both of these brief presentations were to get the audience in the mind of thinking about alternatives when it comes to imagining how the Climbers would work.  The audience then broke up into 5 brainstorming groups where these ideas and others were discussed.  Each group then made a brief presentation about their deliberations and some very interesting ideas were proposed.  Dr. Peter Swan and Skip Penny are going to summarize these and post them on the ISEC website within 60 days.  Of course I’ll have a post here on the blog about it.

The day wound up with an Evening Mixer at the Museum of Flight’s Red Barn Gallery.

It was a wonderful first day and everyone who attended thoroughly enjoyed it - more tomorrow!

Obayashi releases a video about the Space Elevator

The Japanese construction company Obayashi (remember them?) recently released a “conceptual construction” video about the Space Elevator.  You can view the webpage with the video here.  Actually, there’s no actual construction shown, but it’s a cool video nonetheless.

The webpage is in Japanese, of course, so if that’s not a language you can read, I would recommend you open up this page with the Google browser Chrome and let it translate it for you.  There doesn’t appear to be any audio however, but as I don’t understand Japanese, I don’t miss it.  But some music would have been a plus :) There IS audio - lesson here is to have a headset plugged in AND properly configured. The music is very reminiscent of the Alan Chan video.

Carbyne - what do we have here?

This is truly interesting.  As reported in the paper Carbyne from first principles: Chain of C atoms, a nanorod or a nanorope? (and if I’m reading the paper correctly), the specific strength of Carbyne is on the order of 75 MYuris, well within the range needed to build an earth-based space elevator.

However, there does appear to be at least one fly in the ointment - material stability.  It seems that if you have more than one strand of Carbyne that contacts another one, cross-links will form and will degrade the material’s strength.  Money quote from the article; “…This barrier suggests the viability of carbyne in condensed phase at room temperature on the order of days…”  So, maybe not quite there yet.

I did a little net-sleuthing and found a short article/comment (Carbyne and other myths about carbon) by Dr. Harry Kroto, a co-recipient of the 1996 Nobel prize in Chemistry.  It is almost 3 years old and in it, he also raises the issue of material stability (to put it mildly).

Carbyne from first principles… has five authors.  Three of them (Dr. Boris Yakobson, Vasilii Artyukhov and Mingjie Liu) are also the authors of a paper in the current issue (Vol 2 / No 1) of CLIMB.  They also presented a paper at the 2011 Space Elevator conference which won an Honorable Mention in the Artsutanov competition.

I will be corresponding with these authors (and, hopefully, Dr. Kroto) over the next several days and will report back on what additional information I can glean - stay tuned!

Volume 2 of CLIMB now available!

Volume 2 / Number 1 of CLIMB, the Space Elevator Journal, is now available in printed format!  This issue contains some of the best, peer-reviewed Papers relating to a space elevator that have been written since Volume 1 was released in December of 2011.  It also includes, as Volume 1 did, several Additional Reading articles which we at ISEC think will be of great interest to the Space Elevator enthusiast.

Volume 1 of CLIMB was the “Yuri Artsutanov” issue and Volume 2 of CLIMB is the “Jerome Pearson” issue.  We have honored these engineers in the first two issues of CLIMB as they were the original inventors of the Space Elevator concept that is referenced today in all serious work on this subject.  I’d like to also note that Jerome Pearson will be the Keynote speaker at this year’s Space Elevator Conference (you are coming, aren’t you?) and will be at the conference all 3 days.  It will be a great opportunity for you to purchase a copy of CLIMB at the Conference (unless you have already received it as part of your membership benefits) and have Jerome autograph it for you.

The plan is now to publish future issues of CLIMB each year in the June/July timeframe, this to be coordinated with the annual Space Elevator Conference.  So, you can look forward to future issues of CLIMB each year.

To purchase Volume 2 of CLIMB, or any other ISEC publication, visit the ISEC Store or our publisher, Lulu.com.

Enjoy!

Weird but True (4)

In the National Geographic children’s book Weird but True 4: 300 Outrageous Facts, one of the items mentioned is the Space Elevator.  It shows the Mondolithic conceptual graphic of a Space Elevator and the fact mentioned is “In the future, you may be able to take a Space Elevator thousands of miles above the earth.

I’m pretty sure this is a direct result of the NatGeo article on the Space Elevator that ISEC was able to contribute to a couple of years ago.

A Tedx Talk about the Space Elevator

Earlier this year, Markus Landgraf, a Mission Analyst at the European Space Agency, gave a TEDx talk about the Space Elevator.  It was well done and worth the 19+ minutes of your time it will take you to listen to it.

He discusses the long CNT fibers made by a company in China and proposes using these to make an SE Cable.  The problem is, is that they’re just not yet “pure” enough to do so.  Nano-threads spun from CNTs are, so far, full of kinks and defects - the technology is just not yet there to make them like we need to have them be.  But technology continues to attack the problem and I think it’s only a matter of time…

KONE UltraRope

A recent article in The Economist talked about the KONE corporation, based in Finland, introducing a new, high-strength, carbon-fiber based rope for the conventional elevator industry called “KONE UltraRope“.  I was unable to find any information on the KONE website about actual strength measurements of the material, but did glean some snippets from other articles discussing it.  For example:

NewScientist reports: “UltraRope beats steel for tensile strength but weighs only one-seventh as much.”

Gizmag says: “…UltraRope is said to be twice as strong as steel…”

Several sources, including Phys.org report: “UltraRope has a carbon fiber core with high friction coating. The carbon fiber core lasts longer than conventional steel ropes, said KONE. UltraRope is highly resistant to wear and abrasion and, unlike steel, the structure does not densify and stretch.”

For comparison purposes, Toray Carbon Fibers America reports that its own carbon fibers have a tensile strength of approximately 6 GPa-cc/g but in useful (i.e. composite) form, “only” about 3 GPa-cc/g, on the order of the same strength as Dyneema or Spectra.

So, can we build an earth-based Space Elevator yet with UltraRope?  We can definitively say “No” to that.  But is this material strong enough to have won the NASA Strong-Tether challenge?  The answer is, well, “maybe”…  There just isn’t enough material out there (that I have been able to find) to make a determination one way or the other.

But I have emailed KONE for more info and if they provide it, I will post it here.

Regardless, it’s exciting to see carbon-fiber materials being used in applications like this (and in an elevator no less!) and one can only hope that the manufacturing knowledge being gained here will, someday down the road, be applicable to an earth-based space elevator.  The Economist understood this well when they concluded:

“Nor need carbon-fibre lift-cables be confined to buildings. They could eventually make an idea from science fiction a reality too. Space lifts, dreamed up in the late 1950s, are a way of getting into orbit without using a rocket. Building one would mean lowering a cable from a satellite in a geosynchronous orbit above the Earth’s equator while deploying a counterbalancing cable out into space. The cable from Earth to the satellite would not be a classic lift rope because it would not, itself, move. But it would perform a similar function of support as robotic cars crawled up and down it, ferrying people and equipment to and from the satellite—whence they could depart into the cosmos.”
