The feasibility of a miniature manually-driven BLDC power system will be investigated. The combination of newly developed high energy density magnetic materials, efficient low gear ratio transmissions, and switching converter electronics will be applied to generate high electrical power. Preliminary results show that 100-200 watts could be generated in a very lightweight unit at controlled output voltages and currents. The power system will be able to safely recharge batteries at high rates, or drive mobile electronic devices directly. A successful result would provide unlimited field electricity to troops engaged in protracted operations in remote locations. No fuels, maintenance, disposal, shelf life, or logistics would be required. High efficiency operation would minimize wasted effort. Troops would retain their mobility and operation of devices like night vision, communications, GPS, laser targeting, and data display/computers. The chargers would also address the $60B commercial battery market. Consumers and civilian emergency workers could manually charge devices like laptop computers, cell phones, GPS, audio/video, radios, flashlights, etc. Commercialization will also improve product quality and lower costs for future military procurements.
