Aerovator
I read about this idea on wikipedia:
http://en.wikipedia.org/wiki/Aerovator. Basically, it is a long aerodynamic ribbon kept up by 20+ jet engines. Somehow, this could be used to get into space, but It doesn't sound very practical to me, though I don't claim to be an expert. I was curious what any of the technically proficient people here thought. |

The ISP of turbofan engines is something like 3600 seconds or more, so it should take quite a lot less fuel to orbit a given payload than a rocket. Now if you could just "tame" a hurricane, you might be able to locate the aerovator in in the eye of the hurricane and use the "heat-engine" of the hurricane for propulsion! Tom |

I was curious what any of the technically proficient people here thought. That's an interesting idea I hadn't seen before. How it could be used to get into space seems pretty obvious to me: you send a payload up the ribbon, and then let it go off the end when its velocity vector is pointing in the desired direction. It has orbital velocity already, so it would need only a small burn to boost it into an orbit that won't hit the aerovator the next time around. I'm no expert either, but it seems like these guys have done their homework. I'd classify it as "intriguing," and I hope more people in the field take a look. |

Some time ago, one of the people here gave a talk in which the proposal was a ribbon maintained by two ground stations and two space stations. Once in place, its own speed would maintain it, with only a little power needed by the stations. This was claimed to give the equivalent of a space elevator at a height of about 200 miles. -- This address is for information only.
