A method and apparatus useful for disposing of the high volumes of produced water associated with coal bed methane natural gas wells. The method taught is to create steam from the produced water and vent the steam into the atmosphere. The apparatus taught utilizes available heat energy sources to produce heat for enhancing water evaporation rates and may incorporate a pre-heater system and/or a mineral separation system.

A solar-powered power generation system and an associated method are provided. The system includes at least one trough solar absorption device for heating a heat transfer fluid to a first temperature, and at least one tower solar absorption device for further heating the transfer fluid to a second temperature. Thus, the generation system can efficiently heat the transfer fluid to high temperatures. Subsequently, the heated fluid can be used, e.g., to generate steam and/or electricity.

A gravitational electric power generating device includes a driving shaft, at least a spinning wheel, and two mount assemblies, in which each of the spinning wheels includes a first spoke rim, a second spoke rim, a wheel hub, and at least a tread-wheel. The two mount assemblies are erected at the two ends of the driving shaft, respectively, and can support both the driving shaft and the spinning wheel on the driving shaft. Using a moving object to move in the tread-wheel, and making use of the g...

Recovery and conversion of geothermal energy from geologically stable, hot, dry rock is disclosed. Deep boreholes are drilled to form a system of feed and return conduits in the non-porous formation. Fluid is passed through the conduits where heat energy is transferred to the moving fluid. The return conduit brings the hot fluid to an energy conversion station located underground where the thermal energy is converted into electrical energy. Power from the generator and warm water are supplied to...

A manual override mechanism is presented for a motor-driven linear actuator that allows the output rack and pinion of the actuator to be manually positioned. Once positioned, the output may be locked by a locking mechanism to prevent this output from translating to its quiescent position. When incorporated in a spring-return linear actuator, the manual override may be used to apply a preload on the spring before the driven device is connected. When the actuator is used to drive a valve or damper...

The intended purpose of my invention is to create a point of origin in system from which driving thrusts could evolve. In this system, vacuum can be developed with less force than it naturally is required to create said vacuum. By posting a cylinder, containing two pistons in each cylinder, on each side of the axis of rotation and having gas flow in an out the cylinders under controlled pressures, the system could create such vacuum. As a result, said vacuum can lift more mass than the mass crea...

An energy exchanger (2) is connected to an earth energy exchanger (18) via a flow line (10) and a return flow line (14). The flow line (10) and the return flow line (14) are both provided with a regulatable stop valve (12, 16). At least one heat-insulated flow pipe (20) is surrounded by a separation pipe (24) in a bore hole (22), whereby a return flow area (28) for circulatory water is connected thereto in a radially outward manner. The return flow area (28) contains at least one return flow pip...

A natural thermo-carrier heat release system that provides open or closed temperature regulation on an object with temperature delta to receive the heat release based on the work principle of descending of a flow at lower temperature and ascending at higher temperature of a fluid.

An energy producing apparatus and method are provided to harness thermal energy from a down hole resource (such as oil or gas) on an offshore rig and to generate electrical power from the thermal energy. This may include a pipe to receive either the high temperature gas or oil and a power module coupled to the pipe to convert thermal energy from the received oil or gas to electrical power.

A solar receiver (2) comprises a housing (4) defining a receiver chamber (12) and an aperture (14); a window (16) mounted in the aperture (14); at least two inlet means (17) axially spaced from the window (16) and positioned at different distances therefrom for the injection into the receiver chamber (12) of different flows of workind fluid; an outlet means (18) for the ejection of the working fluid out of the receiver chamber (12); and absorption control means for the provision of the different...
