How can you bring a mechanic force on the moon? ... ... ... I think you built on it, like...how does that Tesla makes an electricity out of GE DC?

DC is a factory built already, where did you start it the first wire spark? By theory? 

Sometimes, you built enough from that habitant, you will know what you have, you don't have. One thing about the electricity, will one day has to do with the 2 poles. Magnetic. 

Electric Current its a theory beside that magnetic. Its a formula. Well..the electron.
