Researchers have conceived applications Mon, 18 Aug 2008 21:28:55 GMT Herbert Murray http://tech.groups.yahoo.com/group/space-elevator/message/8390 http://tech.groups.yahoo.com/group/space-elevator/message/8390 I know this isn't really that news nanotubes can be used in electronics, but the fact that they are moving out of the lab, into production is a positive step.

Then use a nice long airship? Perhaps for this purpose heat the helium or even use hydrogen if necessary, so long as it stays where the air is thin most Sun, 10 Aug 2008 01:02:45 GMT Andreas http://tech.groups.yahoo.com/group/space-elevator/message/8384 http://tech.groups.yahoo.com/group/space-elevator/message/8384 That doesn't really have much to do with Warren Smith's magnetic catapult.
