The thin film solar field is still a hot bed of activity - Technology Review has a post on a prototype cell that uses photonic crystals - Efficient Thin-Film Solar Cells. Researchers at MIT have unveiled a new type of silicon solar cell that could be much more efficient and cost less than currently used solar cells. Materials science and engineering professor Lionel Kimerling and his colleagues presented results of the first device prototype at a recent meeting of the Materials Research Society in Boston. The design combines a highly effective reflector on the back of a solar cell with an antireflective coating on the front. This helps trap red and near-infrared light, which can be used to make electricity, in the silicon. The research team is licensing similar technology to StarSolar, a startup in Cambridge, MA.

Here's a wave power technology which you may not have heard of: It's called the Searaser and (though only in prototype stages, I've got some reservations about how well it may scale up, as well as the name which somehow I always see as 'Sea Eraser') it may be worth watching. The principle is fairly simple and proven in a different context: Use the Searaser to pump quantities of sea water up a hill where it can be stored in ponds until needed and then released downhill to drive hydroelectric turbines to create power. This is how the Searaser works:

It looks more sleek and futuristic (or retro-futuristic, if you're much versed in vintage SF) than other prototypes, a creature more adapted to fictional outer space than to the oceans. But something about its bulbous main compartment led us to wonder if there is enough room inside for seasteaders to muck about with nation-building. Amidst all those noisy condensers and turbine generators and navigational gears, perhaps even inspired by them, they try to formulate the mechanics of a new micro-civilization, new identities and new cultural traditions.

One Wash, One Cup of Water: Nearly Waterless Washing Machine Invented - 0 views

British inventors have designed a washing machine that takes eco-friendliness to a new level: it uses just a single cup of water to wash a load of clothes. Instead of water the Xeros machine uses thousands of special plastic chips (about 44 pounds' worth) in each wash, and when that single cup of water is heated, these chips absorb the dirt-including tricky stuff like coffee and lipstick. The chips are removed when the wash ends, and can be reused up to 100 times. Though it's still in prototyping, the inventors are intending to commercialize their machine, and it may even hit the shops next year for a price similar to conventional machines.

A British company is poised to construct the world's first floating wind turbine, in a move that could herald a new generation of cheaper, less problematic wind energy. Blue H, a firm registered in the UK but based in Holland, aims to anchor its prototype device 12 miles off the coast of southern Italy later this month.

AFS Trinity Power has developed patent-pending technology that makes it possible for plug-in hybrid electric vehicles to achieve 150 MPG, go 40 miles in all-electric mode, and use gasoline for additional unlimited miles in hybrid mode. In July 2007, in order to very quickly demonstrate all of the key attributes of this technology, the company mounted an effort to build two fully operational XH-150 SUV prototypes using off-the-shelf components. The two vehicles-modified Saturn Vue SUVs-were built in less than six months. They were unveiled on January 13, 2008 at the North American International Auto Show in Detroit (Press Announcement) and (Salon.com test drive report).

Technology Review has an update on cheap, energy efficient OLED lighting - Ultra-Efficient Organic LEDs. An organic light-emitting diode (OLED) developed in Germany has the potential to produce the same quality of white light as incandescent bulbs but with power efficiencies considerably better than even fluorescent lighting. The prototype OLED could emerge as an ultra-efficient light source for displays and general lighting, says Sebastian Reineke, who led the research at the Institute for Applied Photophysics, in Dresden, Germany. The long-term goal is to fabricate the device using conventional low-cost roll-to-roll printing. In recent years, many countries have begun looking to switch from incandescent lighting to compact fluorescent bulbs because the latter are so much more energy efficient. There has also been a lot of interest in using light-emitting diodes (LEDs) for displays and general lighting, again because of the potential energy savings they offer. But with both fluorescent and LED lighting, the quality of white light produced has always left something to be desired. Fluorescent lighting can make people appear unhealthy because less red light is emitted, while most white LEDs on the market today have a bluish quality, making them appear cold.

Building a New Life: Creating Green Fields in Space - 0 views

Biologists and botanists are particularly excited by the project; they believe that close study of the flora and fauna in this artificial environment will improve our understanding of the delicately balanced ecological systems of the earth. But the many applications of Biosphere two are not just earth-bound; lessons learned from the project could have profound implications by paving the way for the creation of future colonies in space.
