Publication number: 20170341770Abstract: An energy harvesting system is provided and a corresponding method for harvesting energy from an aircraft cabin pressurization system utilizing the same. According to one aspect, an energy harvesting system includes an aircraft cabin enclosing a high-pressure environment of pressurized air. An air input receives incoming air from a low-pressure environment and an air output expels outgoing air from the high-pressure environment. A turbine receives the pressurized air expelled from the aircraft cabin and utilizes the pressurized air to produce rotational motion on a turbine shaft. An energy harvesting mechanism is coupled to the turbine shaft and utilizes the rotational motion from the turbine shaft to compress the incoming air or to create electrical energy.Type: ApplicationFiled: May 31, 2016Publication date: November 30, 2017Inventor: Nathan D.

Publication number: 20170309545Abstract: A system and method system for conveying power from a heat source is disclosed. The system includes a conduit constructed of a heat conducting material. The conduit defines a passageway containing a primary working fluid, where the conduit is either mounted upon or extends within at least a portion of a barrier. The conduit is configured to conduct thermal energy generated by the heat source and transfer the thermal energy to the primary working fluid flowing within the passageway. The system also includes a thermoelectric generator in thermal communication with the conduit. The thermoelectric generator has a hot side and a cold side. The primary working fluid transfers the thermal energy to the hot side of the thermoelectric generator to heat the hot side of the thermoelectric generator to a temperature greater than the cold side and create electric current.Type: ApplicationFiled: July 5, 2017Publication date: October 26, 2017Inventor: Nathan D.

Patent number: 9503199Abstract: A system is provided that includes a gateway node and terminal node. The gateway node may be configured to produce a continuous acoustic wave for propagation through a fluid such as water, and detect an echo thereof.

Patent number: 9180382Abstract: One embodiment of a toy (22) having a plurality of balls (12) inside a container (26). Demonstrating ball interactions without the balls (12) making physical contact with one another can be accomplished with a flat, surface (20). To operate the toy (22) the user moves it and therefore its operation does not require the use of an auxiliary object with specific properties. Electrical charge migration in the toy (22) can cause the balls (12) to form patterns that can be used to play games. When the toy (22) is flipped upside down, the balls (12) can roll on the flat surface (18) located above them, which appear to the user as if the balls (22) are defying gravity. Other embodiments are described and shown.Type: GrantFiled: February 8, 2013Date of Patent: November 10, 2015Inventor: Nathan D. Hiller

Patent number: 6914343Abstract: An electric generator system for producing electric power from the environmental temperature changes such as occur during a normal summer day on Earth or Mars. In a preferred embodiment a phase-change mass is provided which partially or completely freezes during the relatively cold part of a cycle and partially or completely melts during the relatively hot part of the cycle. A thermoelectric module is positioned between the phase-change mass and the environment. The temperature of the phase-change mass remains relatively constant throughout the cycle. During the hot part of the cycle heat flows from the environment through the thermoelectric module into the phase change mass generating electric power which is stored in an electric power storage device such as a capacitor or battery. During the cold part of the cycle heat flows from the phase change mass back through the module and out to the environment also generating electric power that also is similarly stored.Type: GrantFiled: December 12, 2003Date of Patent: July 5, 2005Assignee: Hi-Z Technology, Inc.Inventors: Nathan D.
