I haven't seen the video as well, it will be a waste anyway.
You see the battery has to be charged in the first place for it to charge anything else.
Hence the notion of "free" energy is false which is what my original point was.
You just cannot create energy out of nowhere.
One might argue, well how do explosion go about, they seem to be created out of nowhere.
Well the thing is that the chemicals from which the explosion is created have enegry stored in them, its just in the form of potential energy.Once the chemicals are mixed together, that potential energy turns to heat and kinetic energy and you get an explosion.
Energy changes forms, but never ever is destroyed or disappears.
Same case with fuel in a car.The fuel has chemical potential energy, once ignited it changes to heat and kinetic energy, which moves the pistons and now is mechanical energy moving the car.
