>>14293388its not even that hard. you dont need super special materials to construct one. you could even build one using junk yard parts if you were not a dum. of course it would cost quite a bit more to construct it pressurized for the vacuum of space.
but think of a cheap shitty small airplane. a gas engine can provide enough power to make it fly around for hours. you just have to think about how to convert the propeller into a electromagnetopeller.
