Due to their unique operating characteristics and high thermal efficiencies, free-piston engine linear generator (FPELG) has attracted research interest in recent years, thanks to the crankshaft ...

All real heat engines, be it conventional macro engines or colloidal and atomic micro engines, inevitably tradeoff efficiency in their pursuit to maximize power. This basic postulate of finite-time ...

Combustion engines, the engines in gas-powered cars, only use a quarter of the fuel's potential energy while the rest is lost as heat through exhaust. Now, a study demonstrates how to convert exhaust ...
