Patent number: 8656717Abstract: A solar powered generator assembly is provided for driving a turbine using steam produced by solar power. The assembly includes a fluid tank and a fluid line having a first end and a second end each in fluid communication with the fluid tank. A fluid is positioned in the fluid tank and the fluid line. A lens focuses solar rays into a heat collector coupled to the lens. The heat collector has a reflective curved interior surface configured for reflecting solar rays to facilitate heating the heat collector. A medial portion of the fluid line is wrapped around and heated by the heat collector converting the fluid into a gaseous state. A turbine is operationally coupled to the fluid line driving the turbine to produce electrical current.Type: GrantFiled: September 22, 2011Date of Patent: February 25, 2014Inventor: Robert M. Parker

Patent number: 8056825Abstract: An object is to provide a heating tank capable of highly efficiently heating a target to be heated and having high safety and reliability, and a hot water storage tank. The heating tank in which the target to be heated is stored and which heats the target to be heated by a circulated refrigerant of a heat pump, for example, the hot water storage tank which is heated by the circulated refrigerant of the heat pump to produce hot water in the tank includes a heat exchanger in which a wall surface of a tank main body is partially secured to peripheral edge portions and inner portions of two metal plates and in which non-secured portions swell to constitute a refrigerant passage closed except an inlet and an outlet. A thickness dimension of one metal plate is set to be larger than that of the other metal plate, and the one metal plate is arranged on the inner side of the other metal plate.Type: GrantFiled: December 5, 2007Date of Patent: November 15, 2011Assignee: Sanyo Electric Co., Ltd.Inventors: Masahisa Otake, Hiroshi Mukaiyama
