Hydro Turbine Concept Harvests Electricity From Water Pressure


By Evan Ackerman

According to internal polling data that I just made up, the average OhGizmo reader has 16.03 gadgets. That’s a lot, and since most if not all of them require electricity to operate, it’s important to mooch as much of it from other people as possible. The extension cord that you have plugged into your neighbor’s garage can only handle so much current, but soon there may be a way to steal electric power from someone who isn’t expecting it and won’t come after you with a weed whacker: the water company.

This little device gets stuck onto the end of a faucet or inserted into an existing water pipe. It’s got a little hydroelectric turbine in it, and when water moves through, the turbine spins to charge a battery. You can then plug into the battery to charge stuff. It’s not completely free, of course… You’re taking advantage of either gravity or a water company pump somewhere, and you’ll pay for your electricity with a reduction in water pressure caused by the resistance of the turbine. But hey, if you don’t overthink it, it’s free [minuscule amounts of] electricity!

Needless to say, there’s no information on production, but I bet whatever it would cost would be the equivalent of a whoooole bunch of kilowatt-hours of electricity out of a socket.
