MTD DIY Solar Heating System

An MTD (modified trickle down) solar heating system is a good DIY project because it uses less expensive materials, and because of its simplicity to build. It heats water directly, instead of using absorber plates or flow tubes. It uses the same concept as Harry E. Thompson’s Trickle Down Solar Roof. With a MTD solar heating system, an array of MTD collectors forms a single solar roof.

Homemade Solar Batteries

It would be nice to be able to charge your batteries charge without using any conventional electrical chargers. Well, Knut Karlsen did just that.
