  • Patent number: 9768714
    Abstract: This invention concerns an electric drive system (200) for driving an output. The electric drive system comprises: a first electric motor (250) arranged to drive a first input shaft (230) at a first angular velocity, ?1, and a second electric motor (260) arranged to drive a second input shaft (240) at a second angular velocity, ?2. A gear mechanism (210) is provided and is arranged to transmit angular rotation of the first (230) and second (240) input shafts to drive the output (220) at an output angular velocity, ?out, such that ?out is proportional to a?1-b?2, where a and b are constants. The electric drive system (200) further comprises a controller (270) arranged to control operation of the first (250) and second (260) electric motors. When the output (220) is to be driven from ?out=0, the controller (270) is arranged to control the first (250) and second (260) electric motors to drive the first (230) and second (240) input shafts.

  • 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.

  • Patent number: 9718702
    Abstract: A method and system are disclosed for total degassing (CH4+CO2) and density-reducing treatment of dense Lake Kivu deepwater. The invention allows hyper-efficient oxyfuel power generation with return flow water reinjection density-matched at or above ˜150 m without necessity to admix biozone (<80 m) water. This increases the CH4 resource and deflates the gas-rich deepwater layer over time, making Lake Kivu safe against a catastrophe threatening up to 2 million lives. Deepwater from the Main Resource Zone (MRZ, ˜480 m to ˜260 m) is de-densified, then reinjected above the Potential Resource Zone (PRZ, ˜260 m to ˜180 m) within the Intermediate Zone (IZ, ˜180 m to ˜80 m), avoiding wasteful resource dilution of the MRZ or PRZ reserves, and allowing methane extraction from the PRZ and IZ.
