Researchers from Purdue University discovered precisely how fluid boils in capilary cooling sytems, and that by designing a system by using those rules they got a much more efficient heat transfer between the object to be cooled and the liquid.

Hydrogen is the most looked for energy storage, but using it is very expensive due to the fuel cell - the device that has to convert the hydrogen into energy, with its only output pure water. Because fuel cells use a platinum based material to work, they are very expensive - about $4,000 for powering a normal passenger car. Solutions are being searched for making fuel cells cheaper, more efficient and more durable, with millions of dollars poured in every year.

National Science Foundation proved after a long study that nitrogen added to soil can make forests absorb more dioxide carbon. But even if nitrogen is one of the most abundant element in the atmosphere, it's still a pollutant and can have a dramatic influence on the planet's environment.

Quasiturbine Engine Works With Air

Ovidiu Sandru — Wed, 06 Feb 2008 07:40:53 +0000

Since the Quasiturbine is a pure expansion engine (which the Wankel is not, neither most of other rotary engines), it is well suitable as compressed fluid engine – Air engine or air motor. From the basic 200cc per revolution engine bloc, a compressed air prototype has been built making use of 2 parallel expansion circuits […]
