This is my absolute FAVORITE: solar thermal panels on your roof can heat your house, your water, and generate no-transmission-loss electricity . . . even on a cloudy day! This technology is a game changer!
What If Your Residential Heating System Ran On Compost? What if you could heat your house all winter for free, heat your household water for free, and cook with free gas most of the year? Sound to good to be true? Well, it’s not! And you can get almost everything you need to complete this project for free or next to nothing. Build your own residential heat5ing system in just a few days.
