Idea Description

When water moves from a higher to a lower elevation, there is the potential to capture its energy. An electricity-generating dam is an example. Advances have led to low cost pico hydroelectric generators (<5kW) that are currently being used to power homes in remote areas.

Large flat roofed industrial and commercial buildings collect large volumes of water on their roofs. Installing a series of pico hydro generators in the pipes draining the roofs could harness this free gravity fed energy. Air conditioning condensation water runoff and other water sources could feed into the same electricity generating drainage system.

What will you do if you win $10,000 for this idea?

First, I would utilize free University engineering student brainpower for key calculations on energy generation, type and size of water turbine required, and basic system design.

The prize money would then go toward the purchase of a suitable pico hydro generator. Rebuilding and machining of specific parts to convert the existing generator to its new use would be next. Purchasing an electronic load controller to regulate the voltage and frequency would also be required before actual testing could begin.
