Abstract
A light transmissive insulation system comprising a plurality of layers of light transmissive insulating material, the material being characterized by transmissivity to solar spectrum radiation, and low transmissivity to thermal radiation. A solar pond employing the insulation system is also described.
Claims15
A solar collector comprising:
- a body of material sought to be heated;
- a layer of solar spectrum radiation transmissive insulation;
- and
- means for supporting said layer of solar spectrum radiation transmissive insulation between said body of material and a source of solar radiation and in spaced relationship with said body of material, said layer of solar spectrum radiation transmissive insulation comprising an array of cells operative to minimize heat losses from said body of material through convection and conduction, and being generally transmissive to solar spectrum radiation and generally opaque to thermal radiation, said array of cells also being coated with a coating operative to reduce scattering of incoming solar radiation and to enhance absorption of radiated thermal radiation by said cells.
