    摘要： A method and system for controlling power transfer includes the operations of receiving a power transfer value indicating a power level to be transferred either to or from an energy storage sub-system and receiving an input comprising a rotational speed of a rotating mass in the energy storage sub-system. The operations further include calculating a torque value corresponding to the power transfer value based on the rotational speed of the rotating mass and determining whether the torque value exceeds a maximum allowed torque. The operations further include defining an adjusted torque value as the maximum allowed torque value if the torque value exceeds the maximum allowed torque value or defining the adjusted torque value as the torque value if the torque value does not exceed the maximum allowed torque value, and providing the torque value to a direct torque controller for controlling the torque of the rotating mass.

    摘要： A method and apparatus for extracting water. The apparatus comprises a first and second cooling device and a controller. The first cooling device has a first and second side. The first side heats materials located at the first side and generates a water vapor. The second side cools the water vapor and fluids collected from a source. The second cooling device transfers heat from the water vapor and the fluids flowing through the second cooling device to an environment around the second cooling device. A controller controls a first amount of power delivered to the first cooling device and a second amount of power delivered to the second cooling device based on a temperature for the fluids and the water vapor at an output. Water extracted from the fluids and the water vapor by cooling the fluids and the water vapor is collected at the output.

    摘要： Disclosed is an apparatus and methodology for generating operating power for various desired applications using solar energy. A solar array is formed using a small number of solar cells connected in series to form a string of solar cells and then connecting multiple strings in parallel. Unlike conventional solar arrays, no bypass diodes are incorporated into the array. A power converter is coupled to the array to boost output voltage to a level sufficient to operate the desired application. The power converter may be operated independently or based on output levels of the array, the material from which the solar cells of the array are constructed and the operating temperature of the array or combinations thereof.
