Emissions Control

Prototype energy-saving computer delivers significant efficiency boost

April 14, 2008 Using off the shelf technology researchers have developed a highly energy efficient computer that consumes 70 percent less energy than ENERGY STAR labeled computers. Researchers Peter May-Ostendorp and Nathan Beck of Ecos collaborated with chip makers Intel, AMD and Via Technologies to see how much they could reduce the energy demand of computers operating in today’s business environment by using the hardware makers’ most-efficient computer platforms and adding best-in-class components such as hybrid hard drives and right-sized 80 PLUS power supplies.  Read More

April 10, 2008 Chemists are investigating ways to use carbon dioxide removed from smokestack emissions to make a raw material for the production of DVDs, CD-ROMs, beverage bottles and other products made from polycarbonate plastics.  Read More

Starsense is based on Echelon's LonWorks(R) protocol over power line

April 10, 2008 Streetlight systems are expensive for cities to operate and maintain. They also use a lot of energy — representing almost 40 percent of a typical city’s electricity spending. Echelon Corporation announced at the 2008 Light+Building event in Frankfurt that Philips Lighting, one of the world’s leading providers of lighting systems, has built its new Starsense street light telemanagement system using Echelon’s LonWorks platform, which uses Echelon’s power line transceivers to communicate between lighting fixtures and Echelon’s i.LON SmartServer to provide Internet access and local monitoring and control. It is believed Starsense can deliver energy savings of over 40 percent, reducing cities’ energy bills and carbon footprint.  Read More

Volvo hybrid truck (Ragn-Sells)

April 8, 2008 Volvo has announced that Swedish refuse collection firms Renova and Ragn-Sells will begin regular daily testing of two of the company's hybrid refuse trucks ahead of a market launch in 2009. Using a 7 liter diesel engine and an electric motor that utilizes regenerative braking, the trucks are capable of delivery fuel (and therefore emissions) savings of 20 percent.  Read More

Managing energy consumption

South Jersey Gas is now offering its customers the ability to manage their energy consumption, practice energy efficiency and reduce their energy costs using a free web-based service. Developed by Aclara Software, the new service gives customers access to energy information relating to their utility bills.  Read More

Tidal power breakthrough

Bristol based renewable energy company Marine Current Turbines has completed the first installation phase of the 1.2MW SeaGen Tidal System at Northern Ireland’s Strangford Lough - a site chosen for its combination of fast tidal current and ability to provide shelter from bad weather which may hinder the construction process. It is expected that the breakthrough power plant will be operational around mid-year with its massive 16m diameter twin rotors harnessing the tides to produce the equivalent amount of energy it takes to power 1000 homes. After its final assembly at the Harland & Wolff dockyard in Belfast, the crane barge “Rambiz” positioned the 1000 tonne structure onto the seabed 400m from the shoreline where it will be secured by four pins drilled to a depth of around nine meters.  Read More

April 4, 2008 Here’s a futuristic, car-related technology you won’t see in the next summer sci-fi blockbuster: the algae-powered automobile. Some varieties of the unicellular plant are being tweaked to produce of hydrogen, which can be used to power efficient, environmentally clean vehicles. Researchers at the US Department of Energy’s Argonne National Laboratory believe that algae’s ability to grow pretty much anywhere will enable it to be the energy farm of the near future.  Read More

April 2, 2008 Traditional water-purification techniques such as filtration or distillation attempt to remove the contaminants from water by fluid flow. Reversing this thinking, a new Scandinavian spin-off company is researching a new method of purification that takes the clean water molecules out of the contaminated matter using carbon dioxide gas.  Read More

Eco-friendly LED traffic lights

April 1, 2008 Many of us are being encouraged to make the switch from power-hungry incandescent lights to more eco-friendly illumination technologies like LEDs. In proof that this simple process yields big results, a Brazilian project which saw all of the incandescent-based traffic lights in a Sao Paolo suburb replaced with LUXEON LED-based lamps has delivered estimated energy savings of USD$240,000 and reduced municipal energy consumption by 1340 megawatt hours per year.  Read More

Britain's Lightning GT electric supercar

March 27, 2008 It seems a transatlantic battle is brewing in the high-performance electric sportscar market. As America's Tesla moves into the production phase with its 130+mph Roadster, Britain's Lightning GT is hot on its heels, with prototypes expected to hit the road later this year. The Lightning's power figures are very impressive - 700 horsepower, and 4 second 0-60mph times to almost rival the Tesla's 3.7 seconds. But it's the GT's revolutionary battery technology that might give it the upper hand: Nanosafe's Li-ion cells using nano titanate structures instead of traditional graphite give the GT an incredible 250-mile range, a full recharge time of only 10 minutes, and a life expectancy of 12 to 20 years, or 15,000 charge cycles before the battery performance drops significantly.  Read More
