What's the best way to put kinetic energy in batteries?
What's the best way to put kinetic energy in batteries? When i say best i mean highest mechanical advantage.
The ways i can think of are:
-shaking a magnet through a coil of wires
-spinning a wheel to shake " "
-pedaling to spin the wheel to " ''
-using a lawn mower sort of wheel.
Also to refresh my memory what are the other ways (with a higher mechanical advantage) to move a magnet with coils to generate electricity?
