New faucet design saves energy while saving water

People are familiar with motion-sensing faucets that turn on when people move their hands under them, and automatically turn themselves off, so they don’t have to handle the germy handles. People like that. But Toto takes this design much further with its Ecopower faucet, which saves energy AND water. How? It uses “self-generating hydropower” to automatically recharge a tiny battery in the faucet, thus saving the electricity normally used to make these motion-sensing faucets turn on and off.

“The EcoPower faucet recharges itself every time it is used. The flowing water causes a turbine to spin, creating a current that’s stored in the rechargeable batteries. The faucet will stay charged with as few as five uses per day.”

Why is this so exciting? Because it shows that engineers are beginning to think of ways to save energy in even the most mundane of processes and applications. So the EcoPower faucet uses a mere .25 gallons in ten seconds, and also saves energy by not requiring any electrical energy to turn it on and off. Beautiful!
