This is a very simple heater to make, it uses the principal of friction between rolling liquid molecules set in motion by a spinning action. A small 6 inch unit can heat a room and a 24 inch unit can heat a home. It can be scaled up or down to suit your needs. The money you save on heating bills will more than pay for the cost of the heater, you may even have everything you need to build the heater just lying around the house.
