Ever wanted to save on your electricity bill? If this Piezo Shower concept ever becomes a reality, it would go a long way to helping us reduce our electricity bills. Instead of having to heat up your shower water using an electric heater, it introduces friction and vibration to the tiny fibers embedded within these thin pipes, creating piezoelectricity that warms the water, so by the time the water spurts out from the top, you’ll be enjoying a hot shower. The electricity generated is also capable of powering a waterproof touchscreen controller that counts the number of minutes that you’ve been in the shower and the amount of water used.
