Challenge
Large fluctuations of daytime and night time temperatures in some parts of the world result in expensive heating and cooling costs.

Solution
HydroWall is a liquid material that absorbs and stores warmth and coolness, until it is needed. At the same time, HydroWall is a water storage device that stores rainwater, which for example can be used to fill fire trucks, irrigate the surrounding vegetation or supplement cooling systems that lose water by evaporation.
