Solar energy isn't used to its full potential in the typical modern home, yet a concept like the Water Wall is not so far-fetched. Here we have an innovative solution to for a water heater that's environmentally friendly, space-saving and aesthetically pleasing.
Designed for TOOUT Industrial Design Co. Ltd. by Shi Qiang and Liu Zhong Liang, the tank sheds the metal canister in favor of an aquarium-inspired setup. Essentially, the Water Wall is built into a window in your bathroom, sealed on the sides and sandwiched as a sufficiently spaced-out pair of glass panes. Doubling as a privacy diffuser, the fluid-filled fenestration absorbs the sun's warmth to increase the temperature of the liquid inside. This is then sent to your faucet and shower.
