OSLO Feb 3 (Reuters) – Norwegian solar energy firm REC  said on Thursday it is building a 24-megawatt plant in Italy.
Construction of the facility in Lazio has already begun and would use 100,000 REC solar modules.
“The plant will produce around 37 million kilowatt-hours, equal to the energy consumption of around 14,000 families,” the company said in a statement.

LS9’s bugs are single-cell organisms, each a fraction of a billionth the size of an ant. They start out as industrial yeast or nonpathogenic strains of E. coli, but LS9 modifies them by custom-de-signing their DNA.
Using genetically modified bugs for fermentation is essentially the same as using natural bacteria to produce ethanol, although the energy-intensive final process of distillation is virtually eliminated because the bugs excrete a substance that is almost pump-ready.
The closest that LS9 has come to mass production is a 1,000-litre fermenting machine, which looks like a large stainless-steel jar, next to a wardrobe-sized computer connected by a tangle of cables and tubes. It has not yet been plugged in. The machine produces the equivalent of one barrel a week and takes up 40 sq ft of floor space.

“We think we will have fourth-generation fuels in about 18 months, with CO2 as the fuel stock.”
Simple organisms can be genetically re-engineered to produce vaccines or octane-based fuels as waste, according to Venter. Biofuel alternatives to oil are third-generation. The next step is life forms that feed on CO2 and give off fuel such as methane gas as waste, according to Venter.

Several years ago, SunPower, a unit of Cypress Semiconductor, (CY) realized the top metal plate was reflecting the sun’s rays, cutting efficiency by reducing the percentage of sunlight converted to electricity. So the company decided to put both plates beneath the silicon. It now has an industry-high efficiency of 22% vs. an average of 16%, says analyst Dan Ries of Monness, Crespi Hardt & Co. That means fewer panels are needed to produce power, shaving installation costs and making systems more affordable for homes, which have smaller roofs than most commercial buildings.

SunPower, which says it will earn about $90 million on $740 million in sales this year, expects its prices to be competitive with grid power by 2012, says Vice President Julie Blunden.

It is a battery that looks like a piece of paper and can be bent or twisted, trimmed with scissors or molded into any shape needed. While the battery is only a prototype a few inches (centimeters) square right now, U.S. researchers at Rensselaer Polytechnic Institute who developed it have high hopes for it in electronics and other fields that need smaller, lighter power sources. The battery uses paper infused with an electrolyte and carbon nanotubes that are embedded in the paper. The carbon nanotubes form the electrodes, the paper is the separator and the electrolyte allows the current to flow.

Some students were working on methods to dissolve paper and cast it into membranes for use in dialysis machines. Meanwhile, other students in RPI’s materials science department were trying to make carbon nanotube composites using polymers. The two groups got together and realized they could use paper instead of polymers and combine the two projects. Then came another group of students, also at RPI, who said the project — a thin sheet black on one side and white on the other — looked like an electrical device. And over a period of about 18 months, the groups developed the projects, into a battery, a capacitor and a combination of the two.

This collaborative effort involved the Rensselaer departments of Materials Science and Engineering, Chemical and Biological Engineering, the Center for Biotechnology and Interdisciplinary Studies, and the Rensselaer Nanotechnology Center.

China’s bicycle industry has been developed rapidly. In 2006, the total bicycle output has reached 85 million across the country with the export of 56 million, which accounted for 70 percent of the world bicycle trade volume. Electric bicycle industry has grown rapidly during the recent five years, and the annual sales reached 19.5 million in 2006 with an increase of more than 60 percent compared with that in 2005. Seeing the change from heavy bicycles and light bicycles 10 years ago to sport bicycles and folding bicycles today, we can find the quality level of bicycles is increasingly high. Electric bicycles also have developed from only one or two old simple types in early time to nearly 100 styles of luxury, light motorized and high-grade lithium battery at present. Big change and rapid update shaped the first feature in the bicycle market.

Fortunately there are people that have ventured beyond the question of whether the refrigerator light actually goes off when the door is closed. And they have developed a more energy efficient lighting system for refrigerator cabinets. Now you might be asking: “Why is his a priority? Did they conclude it stays on?” The new LED system designed by Poly Optics is actually aimed at the large commercial units that are often open or feature glass doors. The owners, mostly retailers, of these units want the contents to be well lit without generating excessive heat or consuming more power than is necessary.
