Doug Natelson and graduate student Dan Ward, from Rice University, have discovered how to make a light-harvesting antenna from two gold tips separated by a gap only a few nanometers wide. As light source they used a laser, whose rays, once trapped in the gold tips, get concentrated into a tiny space, increasing the light intensity in the gap by a thousand times.

The thing on the left is a snail, and it’s called abalone. Aside the fact that it’s edible, the abalone taught Angela Belcher, from MIT, how to turn carbon dioxide into rock-solid construction materials and thus sequester the gas for hundreds of thousands of years, instead of burying it underground, which is not as safe and as useful.

Chicago-based Invenergy Wind will build a farm equipped with 125 giant wind turbines on o surface of about 30,000 acre in Gratiot County, Michigan. Being considered Michigan’s largest, the $440 million project will produce 200 megawatts of energy by the end of next year, enough to supply electricity for more than 54,000 homes.

Summerhill Group, which is representing Ice Energy’s Ice Bear product in Canada, probably wishes the system has had more traction. Basically, the Ice Bear system uses off-peak electricity to create large blocks of ice, and then uses that ice during summer peak times to provide cooling — the idea being that it offsets the need to run air conditioners at times when electricity is most expensive.

A personal helicopter weighing just 230 lb created sizzling news when it flew on hydrogen with zero emission. With an ability to carry payloads up to 800 lbs, this pocket Hercules can fly for 90 minutes. Fitted with easy controls, this reaches a speed of 100 knots thanks to a pair of small yet powerful motors mounted on it. Two common and easily available things – Hydrogen peroxide (H2O2) and a catalyst – combined to bring about a milestone in personal aviation history with attention to the environmental issues as well! Avimech has combined these two to power engine in to an innovative machine.

The U.S. Navy’s Seal Beach facility in California is now home to a new $1.9 million solar parking lot, thanks to funding from the federal Recovery Act. Aside from creating new green construction jobs, the new solar facility will save the Navy more than $30,000 per year in electrical costs. It’s just one part of an all-around solar power makeover for the Navy, which just this summer has commissioned another $100 million worth of new solar projects.

A team of researchers from the University of Nevada at Reno is out to prove that sludge from a wastewater treatment plant can be dried, powdered, gassified as biofuel, and then burned to generate electricity, which in turn can run equipment at the same treatment plant. Talk about having your cake and eating it, too! The question is whether the researchers can make their sewage sludge-to-biofuel process operate at a cost low enough to compete with the price of conventional fuels.

The project on construction of a wind power electricity plant on Phu Quy Island has been implemented by the PetroVietnam Power Corporation. The project costs VND335 billion. The plant has capacity of 6MW and includes three 2MW turbines. The plant produces about 25.4 million of kWh annually. It will connect with the 22kV network and work smoothly with the diesel power plant located on the island. The project occupies permanent and temporary areas of 0.74ha and 0.87ha respectively.

Nowadays, batteries are hardly meeting the normal consumer’s demand regarding their capacity and lifetime. Complaints about laptops whose charge lasts too little, or about electric cars not being able to charge as quick and last as long as gasoline are frequent. Amprius, a US-based company, addresses these issues and develops abattery that they say it can hold double the charge of regular lithium ion batteries.
