Zero running cost home heaterSubmitted by mauip3 on Mon, 01/27/2014 - 16:43
I'm not sure if this tech has been posted here so because of all the cold weather I thought I would. It is basically a "free energy" device. Once built and installed it puts out an impressive amount of heat. I have built a small test model and it works amazing. This summer i'm going to build a greenhouse with a few large units to heat it through the winter.
This is one of the video's off of youtube that introduced me to the idea.
