A University of Wisconsin team led by Professor Rolf Reitz has designed a hybrid fueled engine using both diesel fuel and gasoline that is 59.5% efficient. Chemical efficiency at 59.5% is far better than gasoline engines and 10 to 15% better than the 52% maximum in modern diesel truck engines. Professor Reitz is one to [...]

The GoTek engine is actually quite simple and a puzzle when just looking at the line drawings. With a read of the patent it can be explained simply. GoTek Energy has their patent issued and the press, including some major media have noticed, including some of those line drawings to confuse folks. This is an [...]

Washington State University (WSU) researchers have developed the first fuel cell that can directly convert jet fuel or gasoline to electricity. If the fuel cell will scale up economically that could take the 30 mpg automobile beyond 100 mpg. Its a dramatically more energy efficient way to create electric power for planes or cars. The [...]

Fraunhofer-Gesellschaft researchers have developed a compact, safe and sturdy fuel cell system that generates electricity and heat in private households from natural gas. The new fuel cell converts chemical energy directly into electrical energy in a design developed as a simple device for home use. If the design is scaleable it might be a market [...]

Linda Larsson recently defended her doctoral thesis at Chalmers University of Technology, where she has been studying two promising aircraft engine concepts. Of the two, the propeller or dual propeller open rotor can save up to 15% and the geared turbofan up to 4%. Over the past 40 years the average annual increase in passenger [...]
