On display at SinoCES, the Haier PowerPad is a heat exchanger that captures the energy contained within shower water and returns the energy to the hot water tank. Haier claims that the PowerPad can currently capture and return 15% of the energy that comes out of a faucet but hopes to increase that figure to 20-30% once production starts next month.
The PowerPad resides on the floor of your shower where it works to capture energy from your water. It's expected to be available in Chinese markets in one to two months. The device will cost around $600, an investment which might take a while to recoup, admittedly. Surely, devices like this are the future but until the efficiency is increased or the price and convenience improved, I probably won't be bringing one home. More details over at Gizmag.
