Thermoelectric Power Generation Modules, European Thermodynamics. From European Thermodynamics, these thermoelectric power generation (TEG) modules use the Seebeck Effect in order to convert heat into electricity directly. These low-carbon, low-maintenance TEG modules are a reliable and green way to generate electricity. Thermoelectric Power Generation Modules feature the following benefits: ; Compact structure ; No moving parts ; Maintenance free ; Noise free operation ; Low carbon
