A Rippling Graphene Harvests Thermal Energy?

Click For Summary
2D graphene sheets are proposed to harvest thermal energy without a temperature change, challenging traditional thermodynamic principles. The research claims that the random motion of graphene can induce electrical current, which does not violate the second law of thermodynamics, as energy is dissipated in the circuit. Critics argue that the findings have been exaggerated by popular media and emphasize that the results align with established theories of thermal noise. The energy is derived from thermal fluctuations rather than an external power source, with the battery serving only to bias the system. Overall, the discussion highlights the need for careful interpretation of the research and its implications for energy harvesting technologies.
