Sandwich structure enables cheaper, more efficient hydrogen fuel cells

Sandwich structure enables cheaper, more efficient hydrogen fuel cells: "For the predicted hydrogen economy to become a reality, fuel cells must become more efficient and cost effective. Researchers from the University of Central Florida (UCF) claim to have addressed both these problems by creating a sandwich-like structure that allows more abundant materials to be used as catalysts in hydrogen fuel cells."

Futuristic biplane design eliminates sonic boom

Futuristic biplane design eliminates sonic boom: "A throwback to early 20th Century aviation may hold the key to eliminating the sonic boom - at least according to researchers at MIT and Stanford University. Strongly reminiscent of biplanes still in use today, the researcher's concept supersonic aircraft introduces a second wing which it is claimed cancels the shockwaves generated by objects near or beyond the sound barrier."

Subwing – it's sort of like water-skiing underwater

Subwing – it's sort of like water-skiing underwater: "We’ve probably all seen scuba divers on television, hitching rides on the backs of manta rays or sea turtles. For those of us who love the ocean, it looks like a near-magical experience, but ... you shouldn’t do it. Marine biologists will tell you that it’s simply a form of harassment, which the animals themselves don’t particularly enjoy. So, how can you replicate that “flying underwater” experience? Well, Norwegian inventor Simon Sivertsen would suggest you buy his boat-towed Subwing."

75th anniversary of the Mercedes Benz W125 Silver Arrow - 595 bhp and 750 kg in 1937

75th anniversary of the Mercedes Benz W125 Silver Arrow - 595 bhp and 750 kg in 1937: "Before the "space race" became a metaphor for national technological capability, the Grand Prix motor race was regarded, at least by Hitler and Mussolini, as the most readily available way of displaying its world-leading technological prowess. In 1930s Europe, the exploits of Mercedes Benz and Auto Union for Germany, and Alfa Romeo and Maserati for Italy, were powerful tools key to the national interests of their home countries."

Ten Most Extreme Substances Known to Man | Ten Most: "What do you get when you stack carbon nanotubes on their ends and sandwich them together? A material that absorbs 99.9% of the light that touches it. The microscopic surface of the material is rough and uneven, which breaks up the light and makes it a poor reflector. "

Wave Glider aquatic robots set world record

Wave Glider aquatic robots set world record: "On November 17th of last year, a group of four wave-powered autonomous aquatic robots set out from San Francisco, embarking on a planned 37,000-mile (60,000-km) trip across the Pacific ocean. Recently, the fleet of Wave Gliders completed the first leg of their journey, arriving at Hawaii’s Big Island after traveling over 3,200 nautical miles (5,926 km). By doing so, they have set a new distance record for unmanned wave-powered vehicles – that record previously sat at 2,500 nautical miles (4,630 km)."

New production process could cut solar cell prices by half

New production process could cut solar cell prices by half: "Boosting solar cell efficiency is seen as a key factor in making them more practical, but there is another way of looking at the matter ... if the price of those cells were lowered, we could generate more power simply by using more of them. That’s where Mississippi-based Twin Creeks Technologies comes into the picture. The company has developed a method of making crystalline silicon wafers which it says could reduce the cost of solar cell production by half."
