Publication number: 20110225964Abstract: A system for generating electricity includes a pump operable to convert wave motion from a body of water into mechanical energy. The pump includes an input port through which an operating fluid can enter the pump and an output port through which the operating fluid can exit the pump. A first outlet line and a second outlet line are fluidly coupled to the output port of the pump. A first reservoir is fluidly connected to the first outlet line, and a second reservoir is fluidly connected to the second outlet line, both reservoirs being selectively capable of receiving operating fluid driven through the output port.Type: ApplicationFiled: May 27, 2011Publication date: September 22, 2011Inventors: Kenneth W. Welch, JR., Curtis J. Rothi, Harold L. Rothi

Patent number: 7584609Abstract: A system and method generating electricity includes converting wave motion into mechanical power. A fluid matter is driven as a function of the mechanical power to a reservoir. The fluid matter is flowed from the reservoir. At least a portion of a kinetic energy of the flowing fluid matter is converted into electrical energy. The fluid matter may be liquid or gas.Type: GrantFiled: June 6, 2006Date of Patent: September 8, 2009Assignee: Independent Natural Resources, Inc.Inventors: Kenneth W. Welch, Jr., Curtis J. Rothi, Harold L. Rothi

Patent number: 7258532Abstract: A buoyancy pump device for use in fluid. The buoyancy pump device includes a buoyancy block housing defining a buoyancy chamber therein through which the fluid may flow. A buoyancy block is disposed within the buoyancy chamber to move axially therein in a first direction responsive to rising of the fluid in the buoyancy chamber and a second direction responsive to lowering of the fluid in the buoyancy chamber. A piston cylinder is connected to the buoyancy block housing and has at least one valve disposed therein operating as an inlet in response to movement of the buoyancy block in the second direction and an outlet in response to movement of the buoyancy block in the first direction.Type: GrantFiled: March 29, 2005Date of Patent: August 21, 2007Assignee: Indepedent Natural Resources, Inc.Inventors: Kenneth W. Welch, Jr., Curtis J. Rothi, Harold L. Rothi
