Discover how to build a simple DIY Stirling engine powered by heat from candles using an empty spray can and pen components. This step-by-step guide demonstrates how to construct the engine, build a ...

Abstract: The free piston engine generator is a new type of power device. Compared with the traditional reciprocating internal combustion generator, it abandons the mechanical structure of the crank ...

The same tech that could bring back supersonic aircraft may also let data centers continue to operate at scale.

Scientists are learning how to turn the chill of outer space into a quiet source of electricity, using the night sky itself as a heat sink. By carefully managing how surfaces shed heat after dark, ...

Abstract: Starting a free-piston linear engine-generator (LG) involves reciprocating a freely moving piston-magnet-translator assembly between two oppositely placed engine cylinders for combustion to ...
