Not just friction. The power delivered by any generator comes from its
prime mover. In Wimshurst and similar electrostatic machines, the output
power is so low that the load it imposes on the prime mover goes
unnoticed, swamped by friction losses.
You can't win.
You can't break even.
You can't even quit the game.
