wind power requirements:
- Battery inside every train
- battery de-loader when train on launch block (so it gives power to the launch.
- Place a wind mill on every train, so the speed will make it rotate.
- every launch requires energy and every launch the wind mill creates energy of the high speeds...
Or else why not making power out of wheel rotating?
All wheels create power for the launch [:D]
Just some wierd ideas out the top of my head
