Testing the Water Wheel with an Alternator

I tested out an alternator on the water wheel. It works! It would charge the batteries as long as the batteries are close to the wheel. There are a lot of inefficiencies when using a regular alternator. The field and the voltage regulator use some power and the alternator has to spin pretty fast to produce enough voltage to charge the batteries. I need a PMA (permanent magnet alternator) to produce the power I want. In the next video I will show how I convert an alternator to a PMA.
