Abstract/Summary
This project developed a portable hydroelectric generator intended to provide low-power electricity generation for an off-grid cabin in Alpine County, California. The system was designed to utilize naturally occurring creek flow to generate electrical power while remaining portable, durable, and environmentally conscious.
The final system consists of an axial-flow turbine, belt-driven generator subsystem, waterproof electronics enclosure, aluminum support frame, and integrated wildlife protection screening. Engineering analysis was performed to estimate hydraulic power availability, turbine performance, drivetrain requirements, and component lifespan. These analyses guided the selection and development of the final design.
Throughout prototype testing, several design modifications were required. Initial testing revealed that the original alternator-based generation system required excessive startup torque for the available creek flow conditions. Subsequent testing and redesign efforts resulted in modifications to the turbine geometry, pulley ratio, generator selection, and flow-directing components. Additional testing verified waterproof enclosure performance, drivetrain durability, and overall system integration.
The completed prototype satisfied the primary sponsor requirements related to portability, size, cost, material selection, and wildlife protection while demonstrating a practical approach for low-head, low-flow hydroelectric power generation. The final system and supporting documentation were delivered to the project sponsor along with recommendations for future refinement and field deployment.
