Waterwheel Turns Your Faucet Into A Tiny Power Plant

Most discussions of hydroelectric power involve massive underwater turbines or dams that capture the kinetic energy of our constantly flowing waterways. These as huge projects that involve millions of dollars and lots of potentially negative impact on the wildlife that lives in and around those waterways.

Lakes and rivers aren’t the only flowing water to which we have access, however. Water is moving quickly (and almost constantly) through the plumbing of homes and businesses as well. To Korean innovator Ryan Jongwoo Choi, it seemed silly that no one was working on a way to capitalize on this potential energy source as well. So he created the ES Pipe Waterwheel, a tiny faucet accessory that could make big waves in the world of energy conservation.

Choi’s contraption works very similar to that of a typical hydroelectric power plant: rushing water turns turbines which then generate electricity. Only it’s not happening in a massive facility, since the ES Pipe Waterwheel is simple attached to a piece of typical residential plumbing.

As water churns through the ES Pipe’s interior waterwheels, hydroelectric energy accumulates and is stored in the removable bulbs that fit into the top of the pipe, explains Gizmodo. When needed, the bulbs can be removed and used for light.

When creating this concept, Choi researched African countries where many more people have access to running water than reliable electricity. He envisions the waterwheel as a way to help people living in non-electrified communities repurpose the resources they have into much-needed sources of light and power.

We’re not the only ones that see a lot of potential in this nifty gadget: it’s already a finalist in the Industrial Designers Society of America’s 2012 International Design Excellence Awards and is currently being pitched to product manufacturers for production.

    could medications w/transmitters ‘find’ a suburban home location?

    Very clever! I noticed in Senegal (West Africa) that isolated villages often had a solitary light pole with a solar light on the top. Maybe this device will be next.

    This can be replicated..and widely introduced especially for depress areas I like the simple technology..

    This might seem like a nice way to “electrify” remote areas, but the inherent energy inefficiency could pose a problem since the system essentially transfers energy in the form of pumped water. We can’t forget that energy losses occur in the pump, the pipes, and surely in Mr. Choi’s waterwheel.
