Design a tree – The ReHeater

The Reheater is an energy saving project for the use in households, public and commercial places. It uses the heat of drainage water to produce electrical energy.

The product depends on a general system that captures the hot water which is draining from the appliance or system that has used it. This hot water is then used to heat a steam solvent (housed in a second tubular system) such as perfluorpetan that can boil at 28 degrees Celsius. This causes the steam solvent to phase change to steam and allows the steam to travel through an insulated tube into a turbine which powers a generator and creates AC-current.
