I believe its somewhere around 21000 mph for escape velocity, the shuttle travels at around 17,000 mph.
As for a linear accelerator, I believe a corkscrew might do the trick. Basically, as it makes one rotation, it moves the satellite one full length of
Let's say you have a one foot sphere satellite, real small. And the pitch or angle of the screw is enough to move the sphere one foot for every
rotation. Probably 45 degrees, but not sure. So as you spin your screw, you ramp up acceleration for your sphere. So you just calculate the RPM
needed to send your sphere into space.
Imagine two low friction rails with the screw between them, and the sphere rides on the rails being pushed along by the screw. You may need some
rails on top to keep your sphere from flying off. A simple jet engine or smaller could probably get it aloft.
The system could probably scale up to accomodate larger loads, bigger screw and drive motor.
If you think I'm crazy, just look at your average vending machine. The pitch in those screws is shallow so the candy doesn't move forward too fast,
and they're only shallow to get more candy in there.
Billion dollar idea....who can build one....
