Trash-To-Gas Power Plant Gets Greenlight
An anonymous reader writes "Beginning in a little more than a week, Green Power, Inc. of Pasco, Washington will be commencing the building of municipal-solid-waste-to-fuel plants for clients around the world, with $2 billion in contracts; now that an EPA ruling has exonerated GPI from an unnecessary shut-down order by the Washington Ecology Department last year. This fuel would be of higher quality and cheaper than fuel derived from crude oil — and it comes from local feedstock, while turning waste into energy. Now your laptop can turn into a quart of diesel fuel to power your trip to the dump. And the ocean gyres of trash the size of Texas can power Texas. This is an update on a Slashdot story from nine months ago. -
Fleischmann to Work on Commercial Fusion Heater
deeptrace writes "California company D2Fusion has announced they are hiring Dr. Martin Fleischmann (of 'Pons and Fleischmann' fame). The company belives that they can produce a commercial fusion based home heating prototype within a year. They are also looking at other applications, such as using it as a heat source for a commercially available Stirling electrical generator." -
Kids Build Soybean Fueled Sports Car
Sterling D. Allan writes "High school students from West Philadelphia High School have designed a sports car that can go from zero to 60 in four seconds and get more than 50 miles to the gallon on soy bean oil. CBS News reports that this unlikely car was the star last week at the Philadelphia Auto Show. Once again, are we seeing the fabled instance of revolutionary technology coming not from the big corporations, but from some unlikely garage. Maybe these guys will open source their design." -
Harnessing Vertical Sea Temperature Gradient
Sterling D. Allan writes "Sea Solar Power Inc., run by three generations of James Hilbert Andersons, has developed a solar power technology that does not fluctuate with the weather, but is available constantly. Their solution is to harness the solar energy stored in the sea by tapping the thermal gradient that exists naturally between the surface and deep waters, using a reverse refrigeration cycle. The modeling and testing done by the Anderson family over three generations since 1962 predicts that the cost of energy generation through this method will be within a price range comparable to nuclear, coal, natural gas, and other contemporary grid power plants. Ocean Thermal Energy Conversion, or OTEC, was invented in 1881 by a French scientist, Jacques Arsene D'Arsonval. SSP should be ready to build their first full prototype 2-3 years from now." -
Milestones and Trends in Renewable Energy
Sterling D. Allan writes "Some reflections and projections: The year 2005 saw large wind power installments come into a price range where they are now competitive with traditional grid prices. 2006 could see several solar designs do the same. Cold fusion was boosted with two, concurrent and independent sonofusion breakthroughs, though the stigma in the name is still deeply seated. 2006 could see floating wind turbines arrive on the commercial scene -- floating in the water like oil rigs, or floating high in the air, courtesy of helium. 2006 will see at least three companies offering after-market kits for adding Brown's gas (H and O from electrolysis, common ducted) to the air intake of vehicles for enhanced mileage and performance. Many other fuel economizing systems are slated to mature in the marketplace. Climate change evidence will continue to mount. It will yet be years before we harness lightning, but stable tornado systems prototypes that tap waste heat from power plants could arrive this coming year. Will 2006 be the year that clean energy becomes more the vogue than cool computer gadgets?" -
World's Largest Solar Array to use Stirling Engine
An anonymous reader writes "Stirling engines are not a neglected or forgotten technology after all, according to a story at PESN. With 20 years of in-the-field fine-tuning, Stirling Energy Systems is now ready to go big -- real big. They signed a purchase agreement Tuesday with Southern California Edison (SEC), to install a 20,000 dish array that will cover 4,500 acres and will be capable of generating 500 megawatts of electricity -- more than all other U.S. solar projects combined -- making this the largest solar installation in the world. Each collector has a 37-foot-diameter array of mirrors to focus the sun's rays on the Stirling engine, which turns the heat into rotational torque for electricity generation. According to a spokesperson for SCE, this purchase will be in their commercial interest, requiring no subsidy in order to compete, implying that the efficiencies of the technology will give them an edge in the market." -
Fiber Optics Bring the Sun Indoors
Sterling D. Allan writes "Fiber optics transmit light, so why not take the light from outside and transmit it inside? According to an exclusive story at PESN, that is what Tennessee company, Sunlight Direct, is now doing. Their 4-foot-diameter solar dish will light 1000 square feet inside -- minus the harmful UV rays -- rendering a more natural lighting feel, which can be hybridized with florescent and possibly LED lighting to provide a constant light level, though the tone changes with the level of light outside. The GPS-based sun-tracking mechanism uses very little energy. Now you can save electricity, cut on heat emissions by incandescent, and improve the feel of your work environment. Beta testing began in June. Product expected in the market in 2007." -
Sanswire Demonstrates First Stratellite
Sterling D. Allan writes "Pure Energy Systems News (PESN) reports that GlobeTel Communications Corp. debuted their Sanswire Stratellite last week to over 300 people, including members of the media, personnel from the U.S. Department of Defense, U.S. and international commercial interests, as well as investors and shareholders. Stationed in the stratosphere, well above the jet stream, powered by film solar photovoltaic units, the device will make wireless communications available anywhere in the U.S., including on airline flights. One Stratellite will have a payload capacity of several thousand pounds and clear line-of-sight to approximately 300,000 square miles, an area roughly the size of Texas."
