  • Patent number: 11655802
    Abstract: Atmospheric solar energy recovery. At least one example is a method comprising: warming a first fluid from heat in atmospheric air, the warming creates an increase in volume of the first fluid; moving a working piston by the increase in volume of the first fluid during the warming, the movement to a first position; holding the working piston in the first position to create a first fixed working volume; exchanging heat in first fluid with a second fluid while the working piston is held in the first position, thereby reducing pressure of the first fluid below atmospheric pressure; and then releasing the working piston; moving the working piston by a first differential pressure between atmospheric pressure and pressure of the first fluid; and converting movement of the working piston caused by the first differential pressure into usable work.

  • Patent number: 11619146
    Abstract: A fluid storage tank can be configured to store a cooling fluid in a liquid state and a gas state. A first heat exchanger can be configured to release heat into the fluid storage tank. A second heat exchanger can be disposed fluidly downstream of the fluid storage tank and configured to exchange heat between the cooling fluid and a heat load. A pressure control device can be disposed fluidly downstream of the second heat exchanger. The first heat exchanger can be fluidly downstream of the second heat exchanger such that cooling fluid, after being heated in the second heat exchanger, passes through the first heat exchanger and thereby heats upstream cooling fluid resident in the fluid storage tank.

  • Patent number: 11614066
    Abstract: A system for storing and generating power is disclosed. The system comprises a first storage reservoir configured to store a first fluid, a second storage reservoir located at a lower elevation than the first storage reservoir and configured to store a second fluid wherein said second fluid has a higher density than the first fluid, and a pump. In some embodiments a generator may be employed. The pump and the first and the second reservoir are operatively connected such that power is stored by displacing the second fluid in the second storage reservoir by pumping the first fluid from the first storage reservoir to the second storage reservoir and such that power is generated by allowing the pumped first fluid in the second storage reservoir to exit the second reservoir. The first fluid is generally a liquid.
