But that’s by no means the only way to make an engine, and one of the slightly more unusual alternatives comes to us courtesy of a vintage Shell Film Unit film, The Free Piston Engine ...

But none of those methods are as efficient as an engine design invented in 1928. It's called a free-piston engine, and until now it's been less than ideal for transportation use but could prove to ...

This has been the case with so-called free piston engines. In its most basic form, the piston in a free piston engine simply oscillates back and forth driven by the alternating combustion energy ...

However, [Attila Blade]’s version of a free-piston type Stirling engine is simple enough to be built in a matter of minutes. To build the engine you only need a test tube, steel wool ...

Slow temperature recovery can threaten the integrity of your work. That’s Stirling Ultracold designed the VAULT100™ to ...

Ferrari has filed a patent for an engine with pill-shaped pistons, a radical departure from traditional circular piston designs. While Honda famously experimented with oval pistons in the late ...

the team is developing a free-piston linear generator as an alternative internal combustion technology. It utilizes a magnetic piston oscillating through copper coils to generate electricity. The FPLG ...
