Wednesday, May 21st, 2008Hui Wu, a scientist from the University of Maryland collaborated with the National Institute of Standards and Technology to discover a new class of materials that can store large amounts of hydrogen into its crystal structure for later release.
Nanowire Superhighway For Thin-Film Solar Cells
Tuesday, May 20th, 2008Electrical engineers from the University of California, San Diego, developed a new method that could lead to the thin-film solar cells of the future, with highly increased performance. Researchers spiked regular solar cells with nanowires that serve as electron superhighways for electrons resulted from the photons of light.
These ’superhighways’ directly take the electrons to the [...]
A New Material Which Makes Fuel Cells 50% More Efficient
Monday, May 19th, 2008Researchers from MIT have announced that they managed to improve fuel cell efficiency with more than 50 percent. The new technology could be very helpful for portable electronics and the key for this discovery was a new material.
“Our goal is to replace traditional fuel-cell membranes with these cost-effective, highly tunable and better-performing materials,” said Paula [...]
Less Material, More Energy
Sunday, May 18th, 2008Doug Selsam found a way to use less materials and get more energy from wind power. This method consists of using dozens of smaller rotors on the same shaft and linked to the same generator. He got his idea for the first time in the 1980’s at a fluid-dynamics class at the University of California, [...]
Biowave Produces Electricity From Ocean Power
Saturday, May 17th, 2008Designers and engineers often use biomimicry (designs based on natural systems) to solve problems and come up with ideas for the products or structures they are working on. BioPower Systems is an Australian company that used it to develop Biowave, an ocean power system that uses the motion of the water to generate electricity.
