In our latest episode of Lexicon, we sat down with Alec Shkolnik, co-founder and CEO of LiquidPiston, to explore how revolutionary engine designs reshape power generation. Alec shared his journey ...

The engine utilizes isothermal expansion through piston chamber liquid nitrogen injection, generating power by heat absorption, vaporization, and piston movement. Because of its high efficiency, the ...

As interesting as this concept is, it still has a long way to go before reaching production lines, not to mention its applications may be limited ...

It's rated at three horsepower at 10,000 rpm and weighs just four pounds, which is significantly lighter than the 40-pound horizontal reciprocating piston engine it's replacing in the go-kart.

Description: Project BLERP aims to design and construct a reusable liquid rocket engine and launch stand that can be re-used and studied by future students at University of Colorado Boulder. The goal ...

Liquid nitrogen is fun stuff to play with ... We’d love to see the same experiment done with a piston-type steam engine, too. Video after the break.

The data obtained in this way provides a much more detailed insight into the operating behavior of an engine than is possible with real aircraft engines. This test data forms the basis for the ...

[Camden Bowen] recently 3D printed a single-piston engine which nearly worked ... Switching from butane to a liquid fuel also solved some problems as well, and using starter fluid also helped ...

The test, performed for the development of the Cosmos engine for the Zero rocket, lasted 10 seconds and showcased liquid biomethane as a sustainable rocket fuel. The combustion chamber test not ...
