Abstract: An in-vitro system capable of supporting tissue growth with a blood supply is described, including a temperature and humidity controlled antiseptic chamber housing a mechanical oxygenator and waste gas removal system, a pumped continuous circulating fluid in a pipe connected to a tissue nidus, exchange membrane and circulating dialysate for waste removal, a nutrient infusion system, and a means of sterilization and immunosuppression. A total artificial life support system is described.

Abstract: The invention comprises the conversion of thermal power into electrical energy. Two dissimilar metals, such as aluminum and brass, are separated by a heat conductive and electrical conductive material. Water makes a good separator. When a fluid is used, it is heated and caused to flow between the dissimilar metals. The metals may be in the form of rectangular plates and they act as electrodes from which the electrical power is tapped by suitable lines. In the above case the fluid is heated and passed between the metals, the internal temperature being greater than the outside of the metal plates. If desired, the outside of the metal plates may be additionally cooled. In a variation, the heat may be applied to the outside of one metal and passed through the metal, the separator, in this case preferably solid, and through the other metal. Again the other metal plate may be independently cooled. The heat can be applied in any conventional manner and solar heat can readily be used.
