The "Seebeck effect" converts a flow of heat into electrical energy. In using thermal losses inherent to internal combustion engines, it seems possible to produce a "Free" quantity of energy substantial power.
The project aimed to apply the Seebeck effect (electricity-heat conversion) to the "lost" hot springs of the internal combustion engines of cars, trucks and military vehicles. Thermoelectric modules aimed to achieve an overall efficiency of 10% (electric power / heating capacity), working on materials and their integration into the exchanger (cascade).
Two prototypes were built (300We and 2kWe) and tested on engines and/or vehicles. The physical phenomena were modelled, the dangerousness of materials and processes were studied.
Development of a competency in France on thermoelectricity in the automotive sector, close to the level achieved by the United States and Germany (who started working in this field since 2003).
- Development of non-toxic and low-cost materials (Mg 2 Si and MNSI), without rare earth or banned substances;
- Identifying locks up for produce these materials/systems in France
The project RENOTER has strengthened French competitiveness and the activities on the territory:
- € 4M R&D;
- +10 technology patents "Unique";
- 2 theses, 5 international presentations;
- 1500 products studs;
- 250 Wel Products for application light vehicles and 350 Wel products for heavyweight implementation;
- 25 employees involved.
