Engineers have built a modern Stirling engine that quietly turns the cold of outer space into steady mechanical power, using ...

We’ve heard rumors for years about engines capable of getting 100 miles to a gallon of fuel, but the reality is much closer than you might think. Josh “Mac” MacDowell says he not only has the engine, ...

For the hot end, an aluminium mount was pressed into soil, transferring the Earth’s ambient heat to the engine’s bottom plate ...

Josh “Mac” MacDowell of San Antonio Texas had a brilliant idea. He took a Stirling engine, a type of engine developed 200 years ago, and added some 21st-century technology to it. The result is a ...

In his attempt to develop the next generation of experimental powertrains, Texas inventor Josh MacDowell has gone way back in time. By pairing modern hybrid batteries and electric motors with a ...

Engineers at the University of California, Davis, have invented a device that can generate mechanical power at night by linking the natural warmth around us to the cold depths of space. The invention ...

For thrifty motorists, squeezing an extra few miles out of each gallon of fuel can become an obsession. But some have been striving for a semi-mythical goal of achieving 100 miles per gallon of fuel ...

Just how small can you make an engine? Two researchers from the University of Stuttgart and the Max Planck Institute for Intelligent Systems, Valentin Blickle and Clemens Bechinger, successfully ...

Here's a top idea - use a Stirling engine that uses the heat from a processor to drive a fan that cools that processor. Stirling engine design is one of those ideas that feels almost illicit - as a ...

The proposed design is based on a Stirling engine – an engine first invented in the 19 th century that uses hot pressurized gas to push a piston. It would use a 50-pound nuclear uranium battery to ...
