Intro: My Solar Furnace
This is not completely my own design. You can find these all over the internet if you do a Google search or a search on you-tube.
I built this because so many people pay so much money to heat their homes and something as simple and cheap as this could off set those costs by hundreds of dollars a year.
There are places you could buy one of these units for around Two Grand but you don't have too. Anyone can build one of these and stop paying to heat your house while the sun is out, offsetting your monthly energy costs and easing the strain on own power grid.
I look forward to a day when every house is equipped with something like this and I hope everyone that reads this decides to build one of these their selves.
