Scientists report the development of two novel devices that derive power directly from evaporation -- a floating, piston-driven engine that generates electricity causing a light to flash, and a rotary ...

Dr. Ozgur Sahin, an associate professor of biological sciences and physics at Columbia University, who has helped develop a floating, piston-driven engine that generates power, most succinctly ...

I love weird engines—give me a rotary, a turbine, or, hell, even a flat-eight and I’ll be happy. That’s why I was so excited when I heard that INNengine of Granada, Spain had produced a opposed-piston ...

A new engine type entering production for kitplanes could find its way into production aircraft. The Dyna-Cam is a cam-drive free-piston engine which is more compact, lighter and smoother, and ...

One of the ten inventors on a new Searete LLC-filed patent for a new type of engine combining attributes of traditional internal combustion and power generators? None other than Microsoft's Bill Gates ...
