Generate power with magnetic pistons.
This website explores how to generate small amounts of useable power
using low rpm magnetic pistons. You will learn how to build a magnetic
piston that can generate ( 7V to 9V) and produce currents from several hundred milliamps up to 1 Amp at 1300 rpm. The magnets used in this project are N50 grade Neodymium magnets 1/2 inch in diameter and
1/2 inch long. These magnets are extremely strong for their size and
light in weight, perfect for building magnetic pistons!

These waveforms represent one complete stroke of the Magnet
and Push Rod Assembly. Push the two Magnets towards one
another and then letting the Magnetic Repulsion Field push the
two Magnets away from each other. The waveforms have a
positive peak and a negative peak. When you hook a motor up
to the Push Rod Assembly the resulting waveform looks alot like
a Sine Wave. This Sine Wave can be rectified and the energy stored
in a capacitor.
