Engine

A nano-scale engine made from tiny charged particles of gold​ has just been declared the world's smallest by researchers at the University of Cambridge who created it.

A team of physicists have just created the world's smallest working engine from a single electrically-charged atom. With an equivalent efficiency (if scaled to size) of an average automobile engine, it actually produces a significant amount of power

An engine powered by frozen carbon dioxide holds the potential to use the natural resources found on Mars to supply the on-going energy requirements of future long-term missions or attempts at colonization of the planet.

A team of researchers from the University of Twente in the Netherlands, the Russian Academy of Sciences, and Germany’s University of Freiburg have developed a micro-engine that burns oxygen and hydrogen, but there’s a small problem; they’re not sure how the thing works.

Inventors Matt Bellue and Ben Cooper are working on a system in which a combustion engine could be run on nothing but water and solar-heated oil.

Researchers at the University of Stuttgart claim to have developed "the world's smallest steam engine," consisting of a single particle.

Two newly-developed coatings could protect the jet engines of airliners from the harmful effects of volcanic ash.
