electromagnetic energy saving space shuttle!! hey! i found that if electromagnetic generators(made of superconducting wires) are enclosed in freezing nitrogen atmosphere(i.e at very low and constant temp.) in absence of any strong electric and magnetic field,maximum electric supply can be obtained. i was thinking if it was fitted in space shuttle having structure like that of cartoons ufo and a large revolving magnetic disk is surrounded to that then one can make a very large energy saving space shuttle that works like helicopter on earth and like a large revolving frisbee disk in space. i applied this fact only on space shuttle as in space one can have very weak electric and magnetic fields that can support this machine.
