摘要： In the disclosed process, the winning of noble or relatively electronegative metals (e.g. Au, Ag, Cu, Ni, etc.) from substantially aqueous solutions containing ions of the metal through the use of relatively electropositive precipitant metals (e.g. Fe, Zn, Al, etc.) is carried out along with recovery or utilization of some of the energy which can be produced by chemical or electrochemical action. In this process, an electrochemical primary cell-like arrangement with a one-fluid or two-fluid electrolyte (wherein the precipitant metal can be an anode) can also provide improvements in the character (orderliness, efficiency, purity of product, etc.) and control of the cementation reactions. For example, bright (high purity) copper can be obtained in a cathode compartment in a two-fluid cell using a scrap iron anode, a pregnant hydrometallurgical cuprous or cupric leach solution as the catholyte, and an external circuit connecting the cathode to the anode. Good copper is also obtained and cementation rates are increased, when the leach solution is used as a one-fluid electrolyte, and an external circuit is maintained. Under some conditions it is advantageous to exclude oxygen from the system.

摘要： A system for gathering solar energy which includes a solar cell having an inlet and an outlet for the transmission of a fluid energy transfer medium therethrough. The fluid energy transfer medium is normally translucent, is provided with an energy absorbing material such as carbon black, with the carbon black being dispersed through the medium possibly aided by means of a detergent or other dispersant. The cell is provided with a sun-viewing inner base surface which is responsive to incident radiant solar energy by either being highly reflective or by being blackened or darkened in order to enhance the heat absorbing properties of the cell structure.

摘要： Photoelectrogenerative cell means comprising, in combination, cell means including an anolyte cell and a catholyte cell, with means being provided for the transmission of solar radiation into the anolyte cell. The anolyte cell includes an electroconductor solution, along with a photoelectrogenerative compound in admixture therewith, the photoelectrogenerative material being dispersed or dissolved in the electroconductive solution. The catholyte cell comprises an electroconductor in solution, and an electrolytically permeable cell isolation means separates the anolyte cell from the catholyte cell. Electrically conductive electrodes are immersed in each of the respective anode compartments and cathode compartments, and are arranged in electrical contact with the respective anolytes and catholytes. This photoelectrogenerative cell recovers energy produced by photoelectrochemical reactions when placed in a cell configuration.
