Hello all! I have longed envisaged a new type of space launching device, one that would be reusable and cheap to operate.My idea is to have a large set of concentric circular tubes laid horizontally in some desert or something. The spaceship would use magnetic levitation to float in the tubes and propel it's self forward (we could also assist in acceleration using rockets). The idea is that you go round and round the innermost tube accelerating until you have reached your maximum gravity. Then a hatch/bridge opens to connect you to the next larger tube and you repeat the process, until you have reached the required escape velocity to achieve low Earth orbit! Then you just point vertical and shoot out of the tube.So can you math boffin work out if this would be at all feasible without these tubes being the size of Russia...or Maybe it would just have to be that big? I'd love to see how you break this one down. I have tried before but couldn't get the acceleration part figured out. Hope you can help!Many thanks,
Michael
