Second Round of Tests

The official Liftport announcement, stating that they have successfully completed their “second round of preliminary tests of its high altitude platform and robotic lifters”.  They were able to launch their platform a full mile into the air while their robotic climbers were able to climb more than 1,500 feet.

CNT Ribbons maximum strength around 35 GPa?

In the email announcement I received about the release of Liftport’s February, 2006 Technical Newsletter, there was also an announcement about a study which had been done by Nicola M. Pugno (available here) stating that, because of “inherent defects” in a Carbon Nanotube cable, it’s maximum strenght would be no more than approx. 35 GPa.  If true, it’s a problem.  But only if it’s true.  Liftport has started a discussion forum on this subject here.
