A Swiss village with about 300 residents evacuated when part of a nearby mountain began to crumble. A glacier collapsed, burying the village. ABC News’ Alexis Christoforous reports on e.l.f. Beauty’s ...

In 1816, engineer Robert Stirling invented his proprietary Stirling engine, an automatic power source operated by ambient heat rather than direct fuel sources like an internal combustion engine.

Beginning with the principles of the Stirling engine, SoundEnergy's THEAC thermal acoustic engine takes heat – either industrial waste heat or solar heat – and turns it into powerful cooling ...

A tiny Stirling engine is one of the coolest desk toys you can have. Since it requires nothing more than a difference in temperature to get going, you can just throw it on your laptop ...

The model Stirling engine is a staple of novelty catalogues, and we daresay that were it not for their high price there might be more than one Hackaday reader or writer who might own one.

The Stirling engine seems like an odd-ball design when you’ve only encountered gas and Diesel engines. Even though the Stirling engine is piston based it doesn’t use valves. It has a sealed ...

Instead a Stirling engine uses hot and cold chambers to expand and compress gas, driving pistons in the process. It's a machine that is remarkably quiet and efficient - where an application can be ...

Two researchers from the University of Stuttgart and the Max Planck Institute for Intelligent Systems, Valentin Blickle and Clemens Bechinger, successfully shrank the Stirling heat engine down to ...
