- Students test 'space postal service' during Foton mission
05-10-2007 · European Space Agency (ESA)
How do you deliver a parcel down to Earth from space without using a rocket engine and fuel? The answer is YES2, a student experiment that was prepared, built and tested at ESA's research and technology centre, ESTEC, in Noordwijk, the Netherlands. Today, YES2 (Young Engineers Satellite) will be transported to Russia; the launch and operations will follow in September.

- MIT's pint-sized engine promises high efficiency, low cost
10-27-2006 · EurekAlert!
MIT researchers are developing a half-sized gasoline engine that performs like its full-sized cousin but offers fuel efficiency approaching that of today's hybrid engine system -- at a far lower cost. The key? Carefully controlled injection of ethanol, an increasingly common biofuel, directly into the engine's cylinders when there's a hill to be climbed or a car to be passed.

- Ultra-intense laser blast creates true 'black metal'
11-21-2006 · EurekAlert!
"Black gold" is not just an expression anymore. Scientists at the University of Rochester have created a way to change the properties of almost any metal to render it, literally, black.The process, using an incredibly intense burst of laser light, holds the promise of making everything from fuel cells to a space telescope's detectors more efficient -- not to mention turning your car into the blackest black around.

- Software patch makes car more fuel-efficient
02-28-2007 · EurekAlert!
A car wastes energy almost continuously. Accelerating a little less or a little bit more than the optimal performance can cause considerable loss of energy. John Kessels has designed a way to save energy by enabling the car to achieve optimal engine performance more frequently. With a relatively small modification it is possible to reduce fuel consumption by 2.6 percent. Kessels obtained his doctorate from the Technical University Eindhoven (TU/e) on Wednesday Feb. 14, 2007.
