Version 0.94 of this rulebook is now up and available for review.  Here you can find the changes from version 0.93 to 0.94 discussed.  Of course everything can be accessed from the Elevator2010 website.  As always, submit comments and recommendations to Ben Shelef at Ben AT Spaceward.org.

Ben also has the following comment on the remarks (here and here) by Professor Mark Welland.

“It’s a known fact that popular journalism, both technical and mainstream, tends to exaggerate claims. There is no argument that the SE CNT tether does not exist yet, and is much stronger than anything we produce today – nothing to the contrary was ever claimed. Still, it is not laughable to predict that totally new technology will result in large improvements, especially when the mechanism of this technology is understood. CNTs are strong enough, and composites and ropes exhibit tensile strengths very close to that of their native fibers. There’s enough evidence that the CNT tether is feasible – saying we can’t get there because we’re not already there is dead-end thinking. Just my 2c.”
