How the Thermoambient Generator works

The Thermoambient Generator uses special thermoelectric modules, type VHETM - Very High Efficiency Thermoelectric Module, to transform ambient heat into electrical energy. The power of each generator depends on the amount of modules installed inside it. Unlike traditional thermoelectric modules (TEGs), VHETM type modules do not need a "cold source" (heatsink) to turn heat into electricity. VHETMs use the Seebeck effect and the Thomson effect, but in a new and totally innovative way. Therefore, they do not need a cold source.

The second important feature of the VHETM is to have an energy efficiency (η) close to 100% without disrespecting the efficiency of Carnot, η ≤ 1–TC/TH. This is only possible because VHETM thermocouples have an absolute zero simulator at the junctions that would traditionally be connected to a cold source. Therefore, even if these junctions are at room temperature, the absolute zero simulator makes the electrons of these junctions behave as if they were around 0 kelvin. This creates a virtual ΔT of about 300 Kelvin, ensuring close to 100% energy efficiency.

In addition to converting ambient heat into electricity, the thermoambient generator can also convert heat from any other source, regardless of its temperature. The only limit is the maximum and minimum operating temperature of the semiconductor materials used in VHETM.
