Or how 'bout this. We build a gigantic ring superconducting electromagnetic track with a diameter of 2 kilometers in the desert and continuously increase the speed of an object until it reaches 10 k/s and then shift the track to an inclined portion that rockets the object into orbit! Amazing! This has been proposed before, but usually with a straight length of track that would have to either be extremely long, or give the satellite a massive amount of speed in a short time.
A recent AirForce study of this very concept has concluded that this device could decrease the cost of launches (and fuel consumed) 100 fold.
The space ring shown here could increase the speed of the object over a period of hours on an infinite length of track. The problem being, of course, that anything travelling in a circle at high speeds is going to have to deal with unfortunate G-forces. The kind of G forces that would have any living organism seeping into the upholstery before launch. Most communications satellites are too fragile for this kind of treatment.
Which is making a lot of people wonder why the Air Force really put together the plan to study the device. Is it really efficient satellite launches they're after, or is it efficient and constant weapons launches. I might have thought that we were beyond that, but I'm marking this one down under 'cool, but dangerous.'
You're over a bit on the cost
