TL;DR: In this paper, the authors present relationships permitting the determination on a horizontal surface of the instantaneous intensity of diffuse radiation on clear days, the long term average hourly and daily sums of diffuse radii, and the daily sum of diffuse radiata for various categories of days of differing degrees of cloudiness.

TL;DR: In this paper, the angular distribution of the scattered radiation to the slope is known, and the flux of this scattered radiation can be estimated from the following exact formula: The flux of scattered and reflected radiation fluxes to the slopes as well as the effective radiation of the slopes is rather complicated owing to the fluxes being considerably non-isotropic.

TL;DR: In this article, a theoretical analysis was made of absorber-surface efficiencies and selective absorber materials were prepared and tested, and it was shown that selective absorbers do have an efficiency advantage over black-body surfaces at temperatures up to 3000 F.

TL;DR: The problems of successful solar space heating are many and varied as mentioned in this paper, and the author's attempts to solve these difficult problems of solar space heat and cooling are reported in this paper.

TL;DR: An inexpensive integrating sphere for direct determination of the reflectance of materials irradiated by solar energy transmitted through the atmosphere of the earth is described in this paper, where reflectance and transmittance measurements of various metals, cloths, and filters are reported and compared to spectral and total measurements made with other instruments.

TL;DR: In this article, the possibilities of the utilization of solar energy in conjunction with different systems for the dehydration and cooling of air, and to endeavour to establish one which will be most suited under the Indian conditions.

TL;DR: In this paper, the authors discussed the control of cell temperature in terms of the absorptance and the emittance of solar radiation by the cell surface using measured values of spectral reflectance to 25 microns.

TL;DR: The use of the solar furnace as a cool, intense light source has recently been reported as discussed by the authors, and this light source now has been used to initiate the photodissociation of nitrosyl chloride, a reaction proposed by Daniels for the photochemical storage of solar energy.

TL;DR: In this paper, chemical batteries, solar energy converters, and nuclear energy devices appear as the most suitable energy systems for satellites and space vehicles for long operational life under the severe environment conditions of outer space.

TL;DR: In this article, a sun trap, using a pool as its own heat collector, is discussed along with more conventional types of solar pool heaters and the possibilities of a floating liquid film to effect the sun trap is suggested as a most promising area of experimentation.

TL;DR: In this article, the authors search for electron transfer spectra of inorganic ions, together with the chemical evidence of light-induced electron transfer and with thermodynamic data needed for interpretation of the spectra.

TL;DR: A thermoelectric converter for use in space vehicles and using a parabolic cylinder reflector is treated in some detail in this article, where the need for curves giving absorptivity, reflectivity, and transmissivity versus wavelength for the range 2 × 10 −7 to 2 ×10 −5 meters is pointed out.

TL;DR: In this paper, a cooking pot with a selective-black bottom surface and convection-shielding skirt was designed for use with a solar reflector, which achieved high cooking power with a reflector of poor optical quality.

TL;DR: In this article, a consideration of the availability and characteristics of solar energy, the sources of profit in conventional energy sources, and the type of industry which could participate in the commercialization of solar-energy applications is examined from the point of view of their profitmaking potential.

TL;DR: In this article, the authors present a graph of the average energy consumption of a 24-hour day for three positions of the sun (six dates throughout the year) and for all latitudes.

TL;DR: In this article, a special testing method is described which makes it possible to determine a property of a specimen for narrow temperature intervals from measurements in the wide-range temperature distribution of an image furnace.

TL;DR: In this article, the authors used the McAdams' equation to calculate the temperature profile of a semi-infinite solid by rapid heating for a short period and then exposed it in the furnace for 1.7 seconds.

TL;DR: In this paper, a small light weight device for conversion of minute quantities of electric current, such as might be useful in satellite projects, is presented, and the author suggests that such an apparatus might be practically used, or at least tested, on the earth in high altitude localities.

TL;DR: In this article, various aspects of the solar cell matching problem arising from the nonuniform irradiation and temperature in an unoriented randomly spinning converter are discussed, and a sample calculation of power output is given.
