Concentrating Solar SolFocus Looking for Funds

Source: http://feeds.feedburner.com/~r/earth2tech/~3/316278921/


SolFocus, which makes systems that concentrate sunlight onto solar cells, has been slowly adding to its war chest over the last year. And according to a report out today from VentureWire, the Mountain View, Calif.-based company isn’t done fundraising just yet, and is looking to add between $60 million and $80 million in a Series C round. That would be in addition to the $95 million that the firm has already raised.

Concentrating solar photovoltaic systems are a weird bird. They fall somewhere between the massive solar thermal plants being built in the desert, and the standard photovoltaic panels that are becoming common on rooftops around the world. Unlike standard solar panel systems, “concentrating PV” setups use arrays with lenses and curved mirrors to focus the sunlight onto cells, which can produce more power with less material — SolFocus notes a 1 square centimeter cell can capture more than 500 square centimeters of sunlight. The setup reduces the amount of largely silicon-based panels used, and can significantly cut down on the cost of the system.

SolFocus is a little over two years old and is trying to grow fast in an attempt to commercialize its technology. The company is already selling select products to customers for installations as test sites, like a 500-kilowatt installation for the Institute of Concentration Photovoltaic Systems program in Castilla-La Mancha, Spain. Last July it bought Madrid-based solar tracking company InSpira to help scale the business by bringing down the cost of the trackers it uses.

The VentureWire report says SolFocus is now looking to raise funds for “growth and manufacturing.” Previously the company was funded by New Enterprise Associates, Moser Baer India, David Gelbaum, Metasystem Group, NGEN Partners and Yellowstone Capital.

Sunlight + Semiconductors = Clean Water

Source: http://feeds.feedburner.com/~r/earth2tech/~3/316947122/


With all the concern over data centers sucking up enormous amounts of power and worries about the many gallons of water required to make semiconductors, one would never think that chips could offer a solution to some of the world’s resource and environmental problems. But the semiconductor industry really, really wants you to use its chips to make life greener.

And in some cases, technology does offer an answer. An engineer from Mexico, for example, has used four different types of Freescale low-power processors to help distill water using sunlight, glass and a system of semiconductors to estimate water needs and deliver it around the house. The Digital Sun Distiller, from Jose Luis Rojas, won a design challenge put forth by chip maker Freescale.

Distillers generally work by taking collected household water and funneling it into a clear chamber box with a diagonal roof that is heated by the sun. The heat is high enough to kill impurities in the water, leaving a film of potable condensation on the roof of the distiller. That condensation then drips down the angled roof into a clean water receptacle.

It’s pretty low tech, but the addition of one of its chip to sense impurities, heat and to direct the water around the home is what made the technology so compelling for Freescale. Rojas plans to use the $50,000 prize money to help bring his product to market.

NHK Projector Features Insane 7680 x 4320 (8K) Resolution [Too Much Hd]

Japanese TV broadcaster NHK has demonstrated Super Hi-Vision, their whopping 32 megapixel, 8K (7680 x 4320) ultra-high definition projector technology using two LCoS projectors with a combined 8,000 lumens brightness and a towering 6.6m x 3.7m 300-inch projection screen. For those of you who are counting, that absolutely obliterates the 4K (3840 x 2,160) full-HD standard. They have even developed a matching 8K studio camera. Once again this begs the question: is there such a thing as too much HD? [CNET]

Mid-Range Graphics Card Showdown: Nvidia 9800 GTX+ Slides Past ATI Radeon HD 4850 [Nvidia]

Source: http://feeds.feedburner.com/~r/gizmodo/full/~3/316482460/mid+range-graphics-card-showdown-nvidia-9800-gtx%252B-slides-past-ati-radeon-hd-4850

Poised and waiting for ATI's latest graphics card to hit, Nvidia immediately fired off the 9800 GTX+, a nimbler version of its behemoth 9800 GTX, aggressively priced at $229 to put serious pressure on the $199 HD 4850. Benchmarks comparing the two weren't available yesterday, but PC Perspective has 'em up now. In short, while the HD 4850 can mostly keep up with Nvidia's older, regular 9800 GTX, the steroid-injected 9800 GTX+ has enough juice to edge it out in almost every single benchmark. The Radeon HD 4850 has about a month on the shelf to itself before the 9800 GTX+ hits though. Check out PC Perspective for more graphs and numbers than your brain wants to deal with on a Friday.

GeoEye-1 Commercial Satellite Packs Military Power [Global Imaging]

Next month, a commercial satellite named the GeoEye-1 will go into the Earth's orbit. Its highest resolution photos—shots that will spot a 16-inch beachball—will be reserved for military use. However, slightly lower resolution imagery will be made available in the commercial sector, like Google Earth.

Military imagery can resolve images as small as .17 square meters. Commercial limitations are about double that size at .36 square meters. The new satellite will be able to capture 700,000 square kilometers a day (which Technology Review points out is roughly the size of Texas).

But the best news is that GeoEye already sells shots to Yahoo, Google and Microsoft that we get to see through their various mapping portals. In other words, we'll soon be getting a free upgrade to our favorite satellite imaging services. Good stuff. So watch the cleavage, ladies, lest you be an unwilling accomplice to the rapidly growing satellite voyeur trend. (Note: if such sites actually exist, please email tips...for research purposes.)
