Tesla passes U.N. battery tests - 0 views

  •  
    The lithium ion car battery created by Tesla Motors has passed a battery of certification tests that effectively remove another hurdle in the path toward selling products. Because they can burst into flames, lithium ion batteries are classified as dangerous goods, according to Erik Toomre, Director of Manufacturing Programs. "Before we ship it to the public, we have to demonstrate that it is safe," he said.

    Last week's news that widening a stretch of the M6 motorway will cost £3bn, or £1,000 an inch, was depressing not just because of the huge sum but for what it says about the government's spending priorities.

Thinking Pink to Produce 'Green' Solar Energy - 0 views

  •  
    When it comes to producing earth-friendly solar energy, pink may be the new green, according to Ohio State University researchers. Scientists there have developed new dye-sensitized solar cells (DSSCs) that get their pink color from a mixture of red dye and white metal oxide powder in materials that capture light.

Printed Electronics World.com: When Will Organic Photovoltaics be Viable? - 0 views

  •  
    The benefits of non-silicon photovoltaic materials are many and varied. Some are transparent, permitting the face of a wristwatch to generate power, the power source having zero footprints. Some, such as Dye Sensitised Solar Cells printed by G24i in the UK, generate electricity at narrow angles of incidence and even with polarised eg reflected light. DSSC designs can use light of all visible frequencies, not just sunlight.

Energy Search Goes Underground -- Courant.com - 0 views

  •  
    When tremors started cracking walls and bathroom tiles in this Swiss city on the Rhine, the engineers knew they had a problem. But the 3.4 magnitude tremor on the evening of Dec. 8 was no ordinary act of nature: It had been accidentally triggered by engineers drilling deep into the Earth's crust to tap its inner heat and thus break new ground -- literally -- in the world's search for new sources of energy.

And the Web site outage culprit was... Hitec | Tech news blog - CNET News.com - 0 views

  •  
    A week after a slew of popular Web sites were knocked offline temporarily by a power outage in San Francisco, the data center for the Web sites has finally disclosed what went wrong. Basically, backup generators made by a Dutch company called Hitec failed to work, according to an update posted to the Web site of data center 365 Main. Here's what happened: transformer breakers at a San Francisco Pacific Gas & Electric power station unexpectedly opened, causing a power surge that cut off electricity to a portion of the city. (PG&E does not know why the breakers opened.) Three out of 10 of 365 Main's 2.1-megawatt backup generators failed to start up, cutting power to equipment of more than 40 percent of the data center's customers for up to 45 minutes.

The Energy Blog: Natural Gas Civic Beats Prius - 0 views

  •  
    Honda's natural gas Civic GX, which debuted in 2006 in California but is now becoming available in other parts of the country, just may be the cleanest mainstream car on the road. At least the American Council for an Energy-Efficient Economy (ACEEE) thinks so. The nonprofit group . . . put the Civic GX at the top of its 2007 environmentally friendly car list, edging out Toyota's hybrid Prius. The natural gas-fueled Civic scored slightly better than the Prius on fuel economy and reduced emissions in ACEEE's battery of tests. It also scored better in terms of the pollution generated in the manufacturing processes.
