Did you have a chance to see the white water sports at the Olympics, like kayaking and canoeing?
If so, you probably noticed that the entire venue was artificial 다운로드. The Lee Valley White Water Centre in the north of London was created out of a vast expanse of flat land 다운로드. The designers, including a firm from Colorado, S20, had to build it all from scratch, including the high-powered water pumps and the speedy, treacherous river umc.
It made for a fantastic set of competitions and, it turns out, a lasting site for Londoners 다운로드. The venue is going to stay open for both recreational activities and as a training site for future Olympians.
And, the Smithsonian blog wrote about an intriguing innovation used in the building of the rapids 구글 번역 어플. They used what looks like Lego blocks to create the river bottom:
Since the earliest whitewater slalom competitions in the 1930s, most artificial courses have been constructed primarily of concrete, with static forms inserted to mimic boulders, logs…S20′s design turns the static features into adjustable plastic modules—a bit like underwater Legos—which can be positioned with a high degree of precision, and moved at no cost, essentially creating a new stretch of river each time 다운로드.

A $25 million federal grant will speed the construction of a solar manufacturing plant in San Diego, in an effort to boost U.S. competitiveness 새벽기도음악 다운로드.
Semiconductor maker Soitec Solar, recipient of the Department of Energy grant, will pour the funds into equipment at its Rancho Bernando-area plant 다운로드. Production is set to start before the end of the year on concentrated photovoltaic modules that use optical lenses to focus sunlight on tiny, highly efficient solar cells 비커밍제인.
A publicly traded company based in Bernin, France, Soitec entered the concentrated photovoltaics business in 2009 with the purchase of Concentrix Solar, a spinoff of the Fraunhofer Institutes, a network of publicly funded research centers in Germany 3월 모의고사 다운로드.
Soitec received the largest share of $37 million in Energy Department grants designed to accelerate high-volume solar manufacturing over the next two years 다운로드.

More about Soitec’s CPV (concentrated photovoltaic) modules:
Soitec’s CPV modules are built on Concentrix technology 다운로드. They use Fresnel lenses to concentrate sunlight 500 times and focus it onto small, highly efficient multi-junction solar cells. This technology has helped us achieve world-leading AC system efficiency increases of 25% in actual operating conditions 다운로드. This is almost twice as high as the efficiency increases achieved using conventional silicon systems.
