Overview of innovation

ThermoVolt™ is an innovative renewable energy system that harnesses thermal energy and converts it into electricity using Peltier cells based on the Peltier effect — a thermoelectric phenomenon where a temperature difference across two dissimilar materials generates an electric voltage. This system captures ambient or waste heat from industrial, commercial, or household environments and transforms it into usable electrical power. It integrates advanced electronic control and processing components to maximise conversion efficiency and ensure stable performance under varying thermal conditions. Designed for sustainability and scalability, ThermoVolt™ provides a clean, fossil-free energy source suitable for powering devices, sensors, or microgrids — particularly in energy-limited or off-grid communities.
