  • Heat pump systems and methods
    Patent number: 12680734
    Abstract: Provided herein are methods and systems for generating steam. The methods may comprise circulating a first working fluid through a first heat pump cycle, circulating a second working fluid through a second heat pump cycle, and transferring heat from said first working fluid to said second working fluid in a heat exchanger coupled to the first heat pump cycle and the second heat pump cycle. In some embodiments, the first heat pump cycle receives heat from an ambient air stream.
    Type: Grant

  • Hybrid drive system with an opposed-piston, internal combustion engine
    Patent number: 11982225
    Abstract: A hybrid drive system has two sources of driving power: a non-combustion drive system to provide mechanical torque and rotation to a driveshaft, and an opposed-piston, internal combustion engine configured to provide energy for the non-combustion drive system.

  • DUAL-CRANKSHAFT, OPPOSED-PISTON ENGINE WITH MECHANICALLY UNCOUPLED CRANKSHAFTS
    Publication number: 20210123389
    Abstract: An opposed-piston engine with two crankshafts includes a first power transducer coupled to a first crankshaft of the two crankshafts and a second power transducer coupled to a second crankshaft of the two crankshafts. The two crankshafts are not rotatably connected, and so are free to rotate independently of each other. Phase relationships between the crankshafts may be controlled by operating the power transducers to increase, or reduce, crankshaft torque. Changes in crankshaft phase relationships cause changes in opposed piston locations, which, in turn, enable control of engine performance factors.
