ABSTRACT:
The apparatus of the invention includes a heat collector which utilizes a dark-colored, conductive, fibrous heat absorber positioned to receive the sun's rays and to absorb heat therefrom. The apparatus also includes heat-transfer means which passes through or flows over the fibrous heat collector and absorbs heat therefrom. The fibrous heat absorber is a large-area sheet, and it is supported so that it has a generally corrugated contour to increase its effective surface area. The heat transfer means may be air or a fluid.
The apparatus of the invention also includes a heat storage apparatus, which comprises essentially a container of metal-coated material such as eutectic crystals which are in liquid form when the heat of fusion has been absorbed and which are crystalline in form when the heat of fusion is given up and the crystals cool.
