[SOLVED] Thermal Harvesting to generate electricity in a forest

All peltier can be basically used as thermolectric generators. But don't be disappointed about the low efficiency.

One side "holding to sunlight" will have about no effect unless you connect a good heatsink to the backside.
 
thank you for your response.

Is there anything else I can use as thermometric generator that has better performance than Peltier?

is there a special circuitry that is associated for efficiently harvesting power?

If you know any information iwth regard to these, please let me know.
thank you.
 

Thermoelectric generators are said to have 5 - 8 % efficiency. https://en.wikipedia.org/wiki/Thermoelectric_generator

The percent value is a fraction of the theoretical thermal efficiency https://en.wikipedia.org/wiki/Thermal_efficiency.

I didn't test it, but I expect that an industry standard peltier module can work well as a thermal generator. It has however a specific thermal resistance, means it needs a certain heat flow to achieve a reasonable temperature diference between cold and hot side.
 
thank you for the information. I need to Incorporated a different way of charging other than solar. so thats why I chose thermal.

regards!
