Free electricity with Pelton wheel and rainwater

How to Harvest Free Energy From Your Roof with a Hydro Electric Generator

Harvesting hydro power from rain gutters! It sounds impossible but it works. This is part 1 of a video series on the theory and implementation of capturing hydro-electric power from the roof.

This is Part 2 of my series on generating power from my rain gutters. This was a huge effort but I’m happy to say it paid off.

In the previous video I connected an off-the-shelf DC generator to a pelton wheel and drove it with runoff from a large section of my roof. Though I calculated 2 watts of available power and planned on only collecting 50% of it, the actual output was only .19 watts. In this video I design and build a permanent magnet alternator then rectify the AC into DC power to see if I can enhance the efficiency. Spoiler alert: it works really well!
