Solar heating cell

DETAILED DESCRIPTION In accordance with the present invention, however, it is proposed that the fluid energy transfer medium be treated so as to contain an in-situ absorbant material, such as carbon black or the like.
The absorbant material is preferably dispersed through the system by means of a suitable dispersant, if total miscibility is not ordinarily readily obtained.
The cell means of the present invention is also provided with an internal energy viewing or receiving surface which is responsive to incident solar radiant energy so as to be a highly reflective or a highly absorbing surface and disposed to view the rays of the sun, preferably normally thereto, with this energy receiving surface being either polished or blacked so as to enhance or otherwise improve the efficiency of the energy gathering system.
In the preferred system, water is employed as the fluid energy transfer medium because of its relatively high thermal capacity, and when water is so employed, carbon black together with a dispersant is also present in the solution.
Normally, a system will contain a charge of water, such as approximately 100 to 1500 gallons of water for a conventional residence, depending upon demands, with the water being arranged to deliver heat to a transfer substance or to a heat storage medium arranged in the interior of the structure.
Conventional heat exchangers including rock chambers may be employed, with, for example 1500 and up to 3000 gallons of water being utilized for assisting in the heating of a conventional residence dwelling.
The surface area required for the solar energy gathering cell is a function of the end use as is the area to be utilized for extracting energy from the transfer medium.
Obviously, flow rates and residence time will be a factor for consideration as well as other design parameters.
Furthermore, changes in state may be undertaken with steam generation a possibility.
Energy from the sun is radiated from the planet in the form of a wide spectrum of wave energy.
Wave lengths shorter than the ultraviolet, as well as longer than the infra-red are provided, including the intermediate visible wave lengths
