First of all, i am young and not with much knowledge. I have a few questions for a project of mine, which i will start sooner... or later. Is it possible to transmit energy/electricity from far away? (Tesla had something similar) How else could we put something in space, other than rockets? (Elevator would need long cable... would be too heavy.What about Slingshot in a long pressurized tube? Using Magnets? ) The idea is to cheaply shoot something in space, by any one (close to sun for example) which could generate electricity by transmitting it back to earth. What other problems does this idea have? Sorry for my ignorance in advance.
