This is the best thread ever! xD

Why the discussion has stopped?!

Btw, obvious improvement is missing - u input 500W and get 2kw, why not short-curcuit the whole thing?
Feed the motor not from the grid but from the output.
This way u will still get 1.5kW output and no need for the grid AC!

And finally perpetuum mobile is achieved.
Btw, conservation of energy is emprirical law, isn't it? Should not be that hard to break ; )
