Systems and method for a hydrokinetic energy device. A hydrokinetic energy device includes a main body including two main wing-shaped spars mounted upon a rotating central hub, and rotatable spar tip turbines mounted at or near an end of each of the main wing-shaped spars, the main wing-shaped spars driving the rotatable spar tip turbines through water, each of the rotatable spar tip turbines including a direct-drive generator and power conversion system that transfers power from a rotating rotatable spar tip turbine to the central hub where the voltage is stepped up and amperage is reduced.

A high altitude atmospheric energy storing apparatus having a new structure, which is conceived to store the energy of low-temperature air located at high altitude in the sky and utilize it as needed, is provided. The high altitude atmospheric energy storing apparatus includes an air tank adapted to store air, an air supply pipe provided such that it extends in a vertical direction and its lower end is connected to the air tank, and a compression device provided in the sky, connected to the upper end of the air supply pipe, and configured to compress air using the wind and supply the compressed air to the air tank through the air supply pipe, thereby enabling air to be compressed by the wind blowing at high altitude and to be then stored in the air tank.

A method of generating power using an airborne power generating craft connected to an anchor using a tether line. The anchor is secured to an underwater floor. Power is generated based on movement of the airborne power generating craft in response to a wind force. A constant length of the tether line is maintained between the airborne power generating craft and the anchor as the airborne power generating craft moves in response to the wind force. The airborne power generating craft is connected to an electrical transmission system through at least part of the tether line. The generated power is transmitted to the electrical transmission system.

A vehicle propulsion system comprises at least two motors. Combustion occurs upstream of a first motor, and a second motor is downstream of said first motor. The first motor is a turbine that drives a primary propulsion element to effect propulsion and a compressor to effect compression. The second motor is an expansion device whose incoming gases arrive from said first motor. The first motor and the second motor intercommunicate energy via electrical, electromagnetic, and/or mechanical means. Pressurized gases that result from said compression, combustion, or both are rendered or wastegated for auxiliary usage such as aerial thrust, vertical takeoff and/or vertical landing, near-vertical takeoff and/or near-vertical landing, pneumatic storage for hybrid drive, pneumatic lift and/or drive for towing and/or raising another vehicle, aerial vehicle steering, aerial vehicle pitch stabilization or manipulation, aerial vehicle roll stabilization or manipulation, and/or aerial vehicle yaw stabilization or manipulation.

A system for using solar and wind energy for electricity generation and thermal regulation. The system may include a high altitude wind turbine, which may generate electric power and conduct cold to the ground and the rest of the system. The cold may be conducted to a crystallization tank, which may also include an input for heat, for example from solar energy. Cold and heat from the crystallization tank may then be stored or used to heat or cool one or more buildings. Generated electric power may be used in conjunction with or separately from the heating/cooling system.

The technology relates to techniques for redundant power distribution and monitoring for lighter than air (LTA) vehicles. A power distribution and monitoring system for an LTA vehicle, can include two or more redundant controllers coupled to a multiplexer in a crossbar architecture. Each controller can control the multiplexer and inhibit the other controller in the case of a failure of the other controller. Each controller can control a power switch to direct power from a power source to an electronic component, and can monitor the power source. In some cases, a first controller receives a signal indicting a failure in a second controller, and the first controller inhibits the second controller and directs power from the power source to the electronic component.
