I recently read (Wired article)that the "winner" of the elevator 2010 contest was an off-the-shelf non-nanotube rope. Were any of the contestants made of...

The standard of argument at the half-bakery site is exceptionally low -- about many things, not just the SE. Even slashdot is better. Nevertheless ... Assuming...
"LEO clean-up may not be a "direct" application of the SE, but since the SE is all about cheaper spaceflight, it could lower the cost of entry into the space...

Not that far fetched. Especially when you consider work being done now by NAS and NASA. Plus recent technolgical advances by companies like but not limited to...
... Yes -- that's why I wrote "candidly." Affordable access to space is a classic chicken-and-egg or vicious-circle problem: we don't do much of it because...
... I understand your reasoning, but I do not think it is going to make anyone buy into SPS who is not an SE aficionado, or vice versa. That is not a lot of...
... There is one niche that SPS could use to become viable. There is enough energy available on Earth. The problem is distributing it. No affluent person in...
