  • Patent number: 4146013
    Abstract: A novel heat pump using solar energy and the heat of dilution of exothermic inorganic salts and organic compounds is disclosed. The heat pump is made up of four parts including a solar energy absorbing surface, a means for diluting the concentrated solution, and heat exchange apparatus to take the heat of dilution and distribute it to the space to be heated.

  • Patent number: 4110980
    Abstract: Agitation of the surface of a body of water by a falling stream of water results in the entrainment of air bubbles which are carried underneath the surface. These air bubbles are collected in a tank having a submerged open bottom. Air pressure is produced within the tank and utilized to perform useful work by operating a pneumatic pressure transformer which in turn produces high pressure air for operating a series of air-lift pumps. In an alternative embodiment a reciprocating piston motor or turbine is positioned in a path of flow between a portion of the body of water containing relatively few air bubbles and another portion containing a relatively large quantity of bubbles. Flow through this path takes place by reason of a difference in densities and is available to do useful work.

  • Patent number: 3932145
    Abstract: A fuel is produced by cleaning coal using an oil as a cleaning medium whereby the sulfur content of the fuel is substantially reduced and the heat content per pound is substantially increased by the reduction of water and other non-combustibles. The process may be used to produce a coal-oil fuel directly.
