What Are the Best Methods for Harvesting Thermal Energy and Their Efficiency?

AI Thread Summary
Thermal energy harvesting methods include thermoelectric materials and molten salts for thermal storage, with resources available on the Department of Energy's website. The Carnot efficiency is a significant limitation in these energy harvesting processes, as it sets the maximum possible efficiency based on temperature differences. For comprehensive information, searching the DOE website and relevant articles on energy harvesting is recommended. Understanding these methods' efficiencies and limitations is crucial for effective implementation. Exploring these resources can provide valuable insights into ambient and solid thermal energy harvesting.

Look up "thermoelectric materials".

Also look at what you can find on the DOE website. I recall DOE being interested in projects with molten salts as thermal storage materials.
 
what's the DOE website?

A well known limitation is the Carnot efficiency. You can't beat that with a cycle powered by temperature differences.
