Energy doubled so easy!

[Zhang Yalin]

If F2=2F1,
then
W1=F1*H 1,   W2=F2*H2,   H1=H2,   W2=W1*2

Hi Zhang yalin,
I am akunkeji, recently right? You also study the leverage?

This is the other graphic from my blog.

Fix a flywheel to a motor, which is set between the spokes of a bike rear wheel. Connect the flywheel with that of the rear wheel. When the motor starts, the flywheel connected to it drives the flywheel connected to the rear wheel in motion, then the rear wheel also moves, the motor and the rear wheel move simultaneously at the same speed. And the rear wheel theoretically moves at an ever increasing speed. The rear wheel can be used to start a generator. Thus the energy gained is much bigger than the energy consumed.

Do you mean that the motor will be turning with the wheel like this?

The motor and the battery are tied to the spokes securely.
