72 series-connected semiconductor elements, mounted between two ceramic plates which in turn are attached to heat-conducting metal. If the metals are exposed to different temperatures, a voltage arises, sufficient to drive, for example, a slightly rotating motor. The thermogenerator can also be run in the other direction, ie. a voltage is connected and a temperature difference is obtained across the metal legs.

• Maximum temperature difference: 58 ºC
• Max current: 4.5 A
• Output voltage: approx. 0.6 V
• Height: 135 mm
