A New Collector of Solar Radiant Energy - Theory and Experimental Verification - Calculation of the Efficiencies 620323

The author illustrates the scientific bases and experimental results of a solar energy collector, which has characteristics enabling it to collect the energy of the sun at a temperature high enough for modern heat engines. This absorber, whose basic part consists of a honeycomb structure, has the property to let the solar energy pass through, and to stop nearly completely the reradiation of the collected thermic energy. It is light and easily packaged in small volume and, therefore, fits space vehicles, for which the only energy available is solar energy.
On earth, its possible low cost might make it economically competitive with the traditional sources of energy.
