Gravity powered lamp generates as much light as 40 Watt bulb
February 22, 2008 09:36 AM - ENN
Clay Moulton of Springfield, Va., who received his Master of Science in Architecture with a concentration in industrial design from the College of Architecture and Urban Studies in 2007, created the lamp as a part of this master’s thesis. The LED lamp, named Gravia, has just won second place in the Greener Gadgets Design Competition as part of the Greener Gadgets Conference in New York City. Concept illustrations of Gravia depict an acrylic column a little over four feet high. The entire column glows when activated. The electricity is generated by the slow fall of a mass that spins a rotor. The resulting energy powers 10 high-output LEDs that fire into the acrylic lens, creating a diffuse light. The operation is silent and the housing is elegant and cord free — completely independent of electrical infrastructure.

The introduction of LED light bulbs into the market has been hindered due to several factors. Namely: lumens (brightness) color (led produce blue radiance vs. white) market promotion and affordability. Although LED bulbs for residential and commercial applications are not quite where they need to be, they are starting to scratch their way into the market this year with more force than ever before.

California to Require Net-Zero-Energy Buildings
February 5, 2008 10:11 AM - , BuildingGreen
Every two years, the California Energy Commission (CEC) releases an Integrated Energy Policy Report in which it makes recommendations for energy policy in the state, including changes to Title 24, the energy efficiency portion of the building codes. In its 2007 report, CEC recommends adjusting Title 24 to require net-zero-energy performance in residential buildings by 2020 and in commercial buildings by 2030. According to Panama Bartholomy of CEC, the commission does not need new legislation to incorporate these goals and is already moving to put them in place. “The 2008 standards will get us closer to these recommendations,”Ł he said, referring to the Title 24 update currently moving through the state’s rulemaking process.
Chinese Factory Turns Environmental Bane into Boon

China is beginning to take advantage of an unusual energy source: cow gas. Cows emit a significant amount of methane, a powerful greenhouse gas, when they belch and flatulate. According to People’s Daily, the world’s largest cow-dung methane power plant started operation on January 21 in China’s Inner Mongolia region. With an investment of 45 million RMB (roughly $US5.7 million) from the country’s largest milk producer, Mengniu Dairy, the plant is able to supply 10 million kilowatt-hours of electricity to the national power grid.
New Solar Panel Technology Stylish and Sustainable
January 31, 2008 09:23 AM - ENN
The key component of the new modules is an organic dye which in combination with nanoparticles converts sunlight into electricity. Due to the small size of the nanoparticles, the modules are semi-transparent. This aspect makes them well suited for facade integration. The new solar cells are being developed by members of the Fraunhofer Institute for Solar Energy Systems ISE, who will be presenting their new technology in Tokyo at Nanotech 2008, the world’s largest trade fair for nanotechnology.
Scientists Call For Urgent Research Into 'Real' Impacts Of Invasive Species

As well as drawing attention to the rising cost of invasive species on a global scale —estimated at US$1.4 trillion in damage — GISP stresses that too much emphasis has been placed on the problems faced by the agricultural sector in developed countries rather than in developing countries and on the “full range of environmental, social and economic costs.”Ł The report also emphasises that due to the lack of knowledge and research available on the severity of individual pests and the options for best controlling them, policy makers are being left in the dark.
