  • Patent number: 9926905
    Abstract: A system that converts acceleration to rotational energy by using gravity to lower a ballast member and buoyancy to raise it when the ballast member is filled with compressed air. The ballast's initial ascent is controlled by a brake member. This ascent causes a rack assembly to rise that actuates a compressor to refill the intermediary tank with compressed air so the cycle can repeat itself. The initial phase begins with the ballast member containing compressed air so it can ascend up a liquid-filled silo, generating rotational energy along the way using a mounted cable that travels around a wire drum. Upon reaching the top of the silo, valves will open allowing water to enter the ballast thereby sinking it to the bottom, creating additional rotational energy.

  • Patent number: 9732671
    Abstract: A method and system are disclosed for safe, efficient, economically productive, environmentally responsible, extraction and utilization of dissolved gases in deep waters of a rare type of “exploding” lake, where methane (CH4) is accompanied by abundant CO2. CH4 is combusted to generate electricity. CO2 usually is considered a contaminant requiring removal to avoid power loss. Cleaning high CO2 levels from CH4, however, is costly and causes CH4 loss. Venting CO2 is environmentally undesirable. Or, if CO2 is disposed in water flow returned to the deep lake, danger persists. CO2 and CH4 are degassed efficiently together and input into oxy-fuel combustion. Three process outputs are: degassed nutrients-rich water flow, power and CO2+H2O exhaust, all usable for industrially productive purposes. Extracting and using both gases together in an integrated method advances safety, economic productivity and environmental stewardship. Previously, it has not been possible to accomplish these ends together.

  • Publication number: 20150101323
    Abstract: A hydroelectric power plant comprising a pipe from a water source in a mountain range which is made to open into a much larger in diameter piston cylinder at a much lower elevation. The piston therein is driven by water pressure to drive a gear train operatively connected to an electric generator on its far end. The piston is made to move slowly under great force, while the generator is made to turn at a much greater velocity, producing electricity. Water pressure may be derived from some municipal water systems. Much less water is expended through the device than by using a turbine, as in U.S. Pat. No. 1,774,603. Instead of a piston, piezoelectric elements may be used with shut-off valves on either side of the elements. By alternating the operation of these valves intense pressure waves may be induced to produce electricity. This obviates the need for turbines and generators for hydroelectric power generation.

  • Patent number: 8978766
    Abstract: A temperature compensated accumulator and method for use thereof downhole in a well. The accumulator may include a housing with separate bulkhead and piston assemblies. Thus, one assembly may include a hydraulic fluid chamber separated from a gas precharge pressure chamber by a piston and the other assembly may include an ambient pressure chamber separated from an atmospheric chamber by another piston. Additionally a pressure relief and check valve assembly may be located at a pressure relief chamber between the other assembly sections. Thus, venting to or from the gas precharge pressure chamber may take place upon exposure to a predetermined decreased or elevated temperature so as to maintain a substantially constant precharge level for the accumulator, for example, in spite of dramatic changes in downhole temperatures.

  • Publication number: 20150047332
    Abstract: A system and method for converting pressure differentials to electricity is disclosed. Initially, a first chamber is empty and a second chamber holds compressed air/fluid. When the device is disposed in the large bodies of water, due to pressure difference inside the first chamber and the ambient pressure, water fills the first chamber. As the water passes through the first chamber, it turns the turbine or creates pressure difference in transducer to produce electricity. The device descends itself in the deeper water column due to added water in first chamber. When the device obtains equilibrium, the compressed air/fluid from second chamber is allowed to flow to the first chamber to evacuate the filled water. The evacuating water again turns the turbine or creates pressure difference in transducer to produce electricity. After evacuation of water, the device will ascend itself to a shallower depth and the process repeats.

  • Patent number: 8950181
    Abstract: Energy can be stored by directing fluid into an expandable receptacle that has a relatively heavy mass above it. The fluid fills the receptacle such that it expands and lifts up the heavy mass above it. At a time when energy is needed, the fluid can be allowed to flow out of the receptacle and through a turbine or hydraulic motor to generate power or electricity. Intermittent or unreliable sources of power can be used to fill the receptacle, or power from a power grid can be used to fill the receptacle at times that are off-peak. During peak-load times, the potential energy of the fluid in the receptacle can be converted to power. The receptacle can also be used to control water flows and can provide a source of power and potable water to a community.
