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 ...

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 ...

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 ...

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

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 ...
