Abstract

Power Chips Plc is in the final stages of developing solid-state thermal conversion devices that allow direct conversion of heat into electricity at 60-70% of Carnot efficiency. This is achieved by letting electrons tunnel across a gap of a few nanometers. Incorporating these devices into special purpose heat exchangers from Varmaraf allows large scale harnessing of geothermal and waste heat by increasing the efficiency of existing plants and making new plants feasible at lower temperatures than currently
possible.
