I have been corresponding with Dr. Brad Edwards who attended the recent EuroSpaceward “Space Elevator Climber and Tether Workshop”. He sent me the following news (and I quote):
“The conference in Luxembourg went very well – including an announcement by Cambridge of 20 GPa CNT threads.”
This rocks, of course, and I am working on getting additional details. There is nothing yet about this on the Cambridge website, but I’m assuming there will be soon.
Stay tuned…
04FEB2008 – Correction. The best fiber strength was measured at 9 GPa, not 20 GPa as I (and others) initially reported.
