Introductionthe Human Power Generator System is small, portable, and dependable - perfect for emergencies, power failures, remote locations, and off-grid applications. It can be pedaled or cranked by hand to charge 12 volt batteries and run small appliances. Incorporate it into your existing 12 or 24 volt system or simply plug your 120 volt appliance into the Human Power Generator System outlet and start pedaling. It's as easy to operate as an ordinary bicycle.

Origins of Electrical Power Plants

This portion of the paper focuses on the origins of electrical power plants from a number ofsources. It is an attempt to contrast the activities of power generation, power plant design andtransportation with the facility of electrical consumption. It is intended as a reference in thelarger picture of interrogating the benefits and assumptions of contemporary electrical power availability.

Invention of Early Electrical GeneratorsSeveral key milestones in the

development of electrical power are outlined here. A nicely detailed sketch of the history of electrical science is available.This section gives key highlights in the history of the development of electrical generators.

Design ProcessThe design of this generator followed a clear path

beginning with research phase where both state of the art and the more applicable DIY designs for small human-powered generators were evaluated. Because of the dynamic nature of the project this phase is ongoing. This was followed by a dedicated design phase in which several initial designs were proposed from which a few were selected to be built based on reasonableness of production and ease use by the end user. These first designs were then submitted to a standard test rubric which was used to evaluate each prototypes weak points and areas for optimization. Revisions of each design were then subjected to this same test to gage improvement and to help identify any areas for further optimization.

Power from Incident RadiationWith so many RF transmitters of various

sorts distributed throughout today’s urban environments, one might consider background RF as a potential power reservoir for mobile devices. Electronic systems that harvest energy from ambient radiation sources, however, tend to be extremely power-limited and generally require a large collection area or need to be located very close to the radiating source.

Optimization

The next phase of the project is to take what has been learned from the first prototypes and optimize them based on the physics governing electromechanical power generation as well as the mechanics involved with having a human prime mover. Ideas such as increasing the number of windings on each core, changing the number of poles and cores were experimented with and the mechanical designs were improved by doing things such as increasing the rotor diameter to increase the rate of change of the flux and include a gearing system to increase the RPM of the rotor. All of these design changes were made with the design restrictions and goals in mind.

Conclusion

At this point in the project it is unclear if all of the design goals, mainly the ability to charge a 12V battery, will be attained however the optimization phase is ongoing. What is clear from research is that a DIY generator at human-powered speed is capable of powering small electronic devices. To make this project viable, performance and efficiency need to be increased.
