Aerovator, Angel fleet, Polywell

[ciphergoth]

Ideas that are currently entertaining me:

• The Aerovator: a spinning wing 2,000km long whose tips rise 100km up and travel at 8 km/s which unlike the Space Elevator can be built (just) with today's materials.
• The Angel fleet: Counteracting global warming with a fleet of 16 trillon solar shades in space between the Earth and the Sun (we can use the Aerovator to put them up)
• Polywell fusion which if it turned out to be possible would save the world - plus we can power the Aerovator with it.

But the tip is at 100km, where the air is so thin that it doesn't even count as being in the atmosphere.

Yes, I think it's meant to be very thin for much of its length.

It may well be bullshit, but it's not a spoof - the guy who named it has put a lot of work into it...
