  • Patent number: 11612045
    Abstract: Smart switch devices, systems, and methods for modifying an existing electrical system to utilize the power state output of a physical switch as an indicator or signal for the operation of a smart home device or system or network of such devices to facilitate interoperability of physical switches with smart devices. The smart switch detects or determines the power state of a circuit and infers the corresponding state of a mechanical switch that operates the circuit. This information is then transmitted to associated smart devices, which may not be physically connected to the circuit controlled by the switch. When the mechanical switch is operated, it can control both electrically attached loads, such as a conventional light or appliance, and wirelessly control unconnected smart devices.

  • Patent number: 11585571
    Abstract: Heat energy storage systems described in this disclosure can be used for long-term storage of large amounts of thermal energy. In some cases, such systems receive electrical energy from renewable energy sources such as solar panels or wind turbines. Using novel techniques, the heat energy storage systems covert the electrical energy to thermal energy that is stored in hot materials such as molten silicon, molten salts, or any other material that can store large amounts of heat. The heat energy storage systems incorporate extremely good thermal insulation of the thermal energy storage tank that contains the hot materials. The systems are also configured to release thermal energy in an efficient manner to an electricity-producing steam turbine using novel heat exchanger systems and techniques that are described. The energy storage systems described herein have a higher overall real-world efficiency than energy storage systems currently available.

  • Patent number: 11564361
    Abstract: Solar radiation is collected and converted to microwave energy by means maintained in outer space on one or more platforms in space. The microwave energy is then transmitted to earth and directed to and constantly focused on one or more segments of a generally circular and slowly rotating tropical depression, which is a precursor to a tropical storm and then a hurricane (alternatively called a cyclone or typhoon). The focused microwave energy interrupts the cycle of vertical upward and downward movement of air, water, & water vapor, and destabilizes the developing rotational motion of the tropical depression, causing it to break up and dissipate, and preventing it from ultimately developing into a hurricane. When not focusing microwave energy on a tropical depression, the microwave energy can alternatively be used to create earth based solar energy, which would help alleviate costs of operating the system solely for hurricane prevention.

  • Patent number: 11563329
    Abstract: A tethered aircraft or balloon carrying a communications base station for rapid deployment in emergency situations. Electrical power is delivered from a generator on the ground using a pulsed electrical supply system in which each power pulse is delivered over a cable and acknowledged, and pulses only continue to be delivered whilst such acknowledgements are received by the ground station. This reduces the risks associated with delivering electrical power over an aerial tether, and avoids the need for an earth (ground) connection, reducing the risk from lightning.
