The document discusses the design of a bicycle powered generator system. It aims to provide low-cost, safe electricity to the 70% of people worldwide without access to power grids. The basic design involves a stationary bicycle connected to an alternator or dynamo that converts the spinning rear tire motion into a DC voltage. Additional components like rectifiers and DC-DC converters ensure a stable DC output that can power devices or charge batteries for storage. Factors like coupling efficiency and maintaining optimal voltage levels are also considered. The bicycle is highlighted as an efficient human-powered mechanism to generate electricity through pedaling motion. A sample prototype budget of 18,000 rupees is also provided.
