PowerPad Uses Used Shower Water to Help Your Water Heater Stay Efficient

The Power Pad is a contraption that you stand on while you shower, recycling hot water to lower the energy usage of your water heater. Clever!

By running the hot water over cold water that's pumped through the pad, it pre-heats water your heater has yet to warm up. With a warmer starting temperature, that water then takes less energy to heat up, saving you money. Manufactured by Haier in China, the Power Pad is set to go on sale there for about $600. If it works well, it will presumably come to the States, too. [GizMag via Engadget]
