The solar furnace

The solar furnace should face the rising sun so that you get the impact of the suns ray when you need it to heat the house.

The suns rays are absorbed by the black painted duct and transferred to the air inside, heating it and causing to expand. This natural convection action provides the force to move the now warm air into the large inlet duct and into the house where you need it.
