Thermogenerator 2.0 Kit
Electricity generation via Seebeck effect from hot water – Kit
€53.55 / inkl. 19% VAT
The kit demonstrates the direct conversion of heat into electrical energy using the Seebeck effect. As in solar cells, electricity is generated directly through processes at the atomic level without moving mechanical parts. The atomic oscillations coupled with heat lead to a gradient in the distribution of electrons and thus to an electrical voltage. Further information about the Seebeck effect can be found here: Thermoelectricity
The actual conversion of heat into electricity takes place in the Peltier element. One side of this flat element is thermally connected to a warm water bath and the other to a cold water bath via an aluminum L-profile. This means that a heat flow at a higher temperature is directed to the Peltier element and a smaller heat flow at a lower temperature is directed away from the Peltier element. The difference between these heat flows corresponds approximately to the electrical energy generated. As long as the temperature difference at the Peltier element is greater than approx. 10 degrees, enough electricity is generated to drive the connected motor with propeller.
The kit is easy to assemble and takes just a few minutes. The following parts are included:
- Peltier Element
- Two water bowls / plastic
- Motor with propeller
- Fastening screws and plates
- Assembly instructions
