Human generators
In the first place, generators and motors, and an input controller, coupled with an efficient energy storage device, the present invention can reduce the overall weight and complexities of mechanical power transmissions, while, at the same time, offer higher overall efficiencies. In addition, the energy output to the output drive device can be controlled, through profiling and with an output controller, to maintain constant output, independent of instantaneous input. Thus, in a human-powered vehicle, constant thrust can be maintained significantly increasing the vehicle efficiency, compared to the cyclical thrust or torque generated using a mechanical system. More specifically, human generators is off-grid applications or for when you just want a little exercise, the human Power Generator from Windstream Power can be pedaled or cranked by hand to charge 12 volt batteries and run small appliances. The product page says the average continuous power that can be generated by pedaling is about 80 watts; 50 watts if you're cranking by hand; a comment from Hugg by a user says 200 watts is attainable (300 if you're Lance Armstrong). The generator is available with a "Portable Power Pack" which includes a storage battery, 300 watt inverter (with 800 watt peak power), LED battery voltage readout, connection cables, and a 120 volt outlet to turn your calories into useful power. For anyone really interested in avoiding grid power, the company's wind turbines and solar applications can also be connected alongside the human power generator to cram even more energy into the power pack. If the Human Power Generators work well enough to power, it’s would be a very useful power in the future.
