Endothermic reactions converted heat energy as electricity?

Click For Summary
SUMMARY

The discussion centers on the feasibility of using endothermic reactions to convert heat energy into electricity. Participants highlight that while chemical reactions are unlikely to achieve this, thermoelectric cells can utilize heat from sources like radiators. However, the efficiency of such conversions at low temperatures, such as those from refrigeration, remains a significant challenge. Overall, the conversation emphasizes the limitations of current technologies in effectively harnessing low-grade heat for electricity generation.

Are there any endothermic reactions that can release the converted heat energy as electricty? How do they work?

I wonder if it is possible to create something that will convert heat to electricty all the way down to refridgerator temps... they you got your personal power generator and a fridge! :smile:

Are you talking about chemical reactions? I doubt it very much.

As far as physical processes are concerned, you could use the heat coming off the radiator to run a thermoelectric cell, but it wouldn't be very efficient.
