Nelson Ireson June 6, 2008 Comment Now! Novel technologies to improve the efficiency of existing vehicles and combustion processes are the quickest route to improved fuel mileage. Hybrid cars are ...

Another day, another means of converting waste heat into something decidedly non-wasteful. This one comes to us from the folks at Cyclone, whose self-starting Waste Heat Engine can apparently be ...

Physicists led by Johannes Roßnagel at the University of Mainz in Germany, the single atom engine is about as efficient as your car at transforming the changing temperature into mechanical energy.

Scientists are working on a heat engine that consists of just a single ion. Such a nano-heat engine could be far more efficient than, for example, a car engine or a coal-fired power plant. Scientists ...

Ford once sketched a road where an engine's pistons never saw oil and engines ran hotter on purpose. In a late‑1980s patent application filed and granted in Europe, the company described an "uncooled ...

With the debut of the 2026 Jeep Grand Cherokee , Stellantis has unveiled its newest gasoline engine, a 2.0-liter turbocharged ...

Rolls-Royce is ditching diesel for methanol with its new maritime engine, described as the world's first high-speed marine ...

Quantum thermodynamics explores the fundamental principles governing energy conversion at the smallest scales, where quantum effects such as coherence and entanglement significantly influence the ...

The heat engine works as its intrinsic spin converts heat absorbed from laser beams into oscillations of a trapped ion. Credit: John Goold, Trinity College Dublin A new heat engine made from a ...
