EcoPinion - Issue 2 | ecoalign - 0 views

  • The second EcoPinion Survey provides further evidence of a green gap between willingness to adopt or purchase green products, services and technologies, and consumer value perceptions around those offerings. While concern for the environment is at an all time high, consumers think that many forms of green technology (renewable, energy efficient or recycled materials) are cost prohibitive, difficult to understand and maintain, and aesthetically unappealing.

Smart Plug To Cut Down Your Power Bill | Got2BeGreen - 0 views

  • Smart plugs would be fitted to all appliances in the home and communicate via radio waves back to a central control panel to calculate how much energy each device is using and when equipment is operating needlessly. For example, if your phone is fully charged it will turn off further supply of energy to the phone.
  • The plug will even have an “integrated motion sensor” to detect minimal activity in a room to shut down devices left on. If something has been shut off that shouldn’t be, a simple flick of a switch to turn it back on again will tell the central controller that you don’t like that particular service being compromised.

IEEE Spectrum: Synthetic Fuel From a Solar Collector - 0 views

  • 7 January 2008—At first blush, you might lump claims about a machine that supposedly turns sunshine, air, and water into fuel in the same category as e-mails insisting that someone in Nigeria will pay you handsomely to help free up a large sum of money. But researchers at the U.S. Department of Energy’s Sandia National Laboratories, in Albuquerque, say they have created a device that can break water into hydrogen and oxygen using sunlight, or in a another reaction convert carbon dioxide, to carbon monoxide that combines with hydrogen to make hydrocarbons such as methanol, ethanol, and even gasoline or diesel fuel. The technology holds the promise of using the same resources as biomass-to-fuel schemes but with potentially greater efficiency, according to the researchers.

GM-VOLT : Chevy Volt Concept Site » Lockheed Martin Signs Agreement with EEStor - 0 views

  • We have previously discussed a secretive Texas company called EEStor, who are reported to be working on a new type of ultracapacitor that can hold 10x the energy in 1/10th the weight of typical batteries, at a fraction of the cost. They have an agreement to produce caps for Zenn electric cars but to date have not shown any prototypes. This has led some to suspect EEStor as not having the technology they report. Today, however, Lockheed Martin, the major U.S. military equipment manufacturer has announced a partnership agreement with EEStor to develop energy applications.

Electric grid meets Web 2.0, savings results - 0 views

  • The Department of Energy has just wrapped up a fascinating experiment in Washington State in which it provided both homeowners and their appliances with tools that can sense stress on the power grid. Homeowners who made use of the tools saved money—approximately 10 percent on their electric bills—and the grid was more stable, too.

IEEE Spectrum: Silicon Nanowires Turn Heat to Electricity - 0 views

  • Two separate teams, one at Caltech and the other at the University of California, Berkeley, reported that they could increase silicon's ability to convert heat into electric current by as much as 100 times. If they can use what they've learned to improve silicon even further, or translate their findings to other materials, the discovery could lead to new ways to cool computer chips, build refrigerators, or get more power out of car engines.

Technology Review: First OLED TV - 0 views

  •  
    Displays that use organic light-emitting diodes (OLEDs) are more vivid than liquid-crystal displays, have much faster refresh rates, and draw less power, but so far, manufacturing difficulties have limited them to small sizes fit only for handheld devices. On December 1, and only in Japan, Sony released the world's first OLED television, featuring an 11-inch panel with a layer of light-emitting organic material just several hundred nanometers thick. Initially, Sony plans to manufacture 2,000 of the TVs per month.

Flow battery maker gets $15 million | Green Tech blog - CNET News.com - 0 views

  •  
    Deeya Energy, which makes large flow batteries to provide backup power to industrial plants, raised $15 million in a second round of financing, according to Venture Wire. The company earlier raised $7.5 million and is building manufacturing facilities in India. What is a flow battery? It's a battery with tanks of electrolytes that effectively let the battery store more energy than normal batteries. The electrolytes flow or circulate through the system. The larger the tanks, the more electricity it can store.

Miasole apparently going with layoffs after all | Green Tech blog - CNET News.com - 0 views

  •  
    Back in October, we called Miasole, which makes copper indium gallium selenide (CIGS) solar cells, about a rumor that the company cut about 50 employees and planned to close its Shanghai operation. Today, VentureWire wrote that sources outside the company say Miasole has laid off 40 employees. Miasole did not comment on the story. Sources in the CIGS world however have been telling us that they had been receiving resumes from Miasole employees for the past several weeks. So even if people haven't been laid off, employees seem to be restless.

ScienceDirect - Energy Conversion and Management : Evaluation of small wind turbines in... - 0 views

  • The island of Barbados is 99% dependent on fossil fuel imports to satisfy its energy needs, which is unsustainable. This study proposes a 10 MW distributed wind energy scheme using micro wind turbines (WT) of horizontal (HAWT) and vertical axis (VAWT) configurations. These units are rated less than 500 W, and the scheme is hereafter referred to as mWT10. mWT10 is compared to the proposed 10 MW medium WT farm by the Barbados Light & Power Company (BL&P). The economic bottom line is the levelized cost of electricity (LCOE). The results highlight the BL&P proposal as the best economic option at BDS$0.19 per kWh, while that of both mWT10 configurations exceeds the conventional cost of BDS$0.25 by two to nine times. This is attributed to significantly higher relative installation and operational costs. However, the financial gap between mWT10 LCOE and the retail price of electricity is much smaller due to a large fuel surcharge passed on to each customer. Annual additional benefits of using wind energy include: greenhouse gas emissions savings of 6–23 kt of carbon dioxide; and anavoided fuel costs of BDS$1.5–5.3 million.

ASU Researchers Use Bacteria To Generate Electricity - Ecofriend - 0 views

  • Researchers at the Biodesign Institute of Arizona State University have come up with an alternative way of generating electricity. In a new study featured in the journal Biotechnology and Bioengineering, lead author Andrew Kato Marcus and colleagues César Torres and Bruce RittmannThey mentioned that they are using the tiniest organisms on the planet—bacteria—for this purpose. They added that they are looking forward to commercialization of a promising microbial fuel cell (MFC) technology. The microbial fuel cell will generate electrical energy by using any kind of waste, such as sewage or pig manure.

Stanford's nanowire battery holds 10 times the charge of existing ones - 0 views

  • Stanford researchers have found a way to use silicon nanowires to reinvent the rechargeable lithium-ion batteries that power laptops, iPods, video cameras, cell phones, and countless other devices. The new version, developed through research led by Yi Cui, assistant professor of materials science and engineering, produces 10 times the amount of electricity of existing lithium-ion, known as Li-ion, batteries. A laptop that now runs on battery for two hours could operate for 20 hours, a boon to ocean-hopping business travelers.
