Quantum dot heat engine works without moving parts
A recent article in Nature Nanotechnology by NanoLund researchers show that a quantum dot-based heat engine can convert heat into work with an efficiency similar to that of similar machines with moving parts. As quantum dot-based engine has no moving parts it may be useful in applications such as nanotechnology and remote sensing. To Chemistry World, Heiner Linke explains: We have shown that we can get close to the same thermodynamic efficiency limits as any other heat engine."
