  • Liquid electricity for cars of the future

    The reason why electric cars aren’t everywhere is simple — at the end of their range, they have to be stationary for hours while the batteries are recharged. This is a pity, because even cars recharged from ‘dirty’ power stations are three times more environmentally friendly than conventional vehicles. That’s because only 20 per cent…

  • Cheney accused of blocking Californian bid to cut car fumes

    The US vice-president, Dick Cheney, was behind a controversial decision to block California’s attempt to impose tough emission limits on car manufacturers, according to insiders at the government Environmental Protection Agency. Staff at the agency, which announced last week that California’s proposed limits were redundant, said the agency’s chief went against their expert advice after…

  • Nanosolar: Power to the people

    Cost has always been the burdening factor weighing down the mass application of solar technology at nearly $3 per watt. In order to compete with the energy produced from coal solar has been in need of finding a way to shrink its costs down to $1 per watt. Nanosolar’s cells use absolutely no silicon as…

  • Vertical garden

    Office walls alive with greenery are now possible with vertical gardens invented by Joost Bakker, an Australian sculptor, who uses raw steel and discarded objects among his construction materials. “I’m not really into luxurious finishes, I like using things that people perceive as ugly”, says Joost.

Although we can’t read Swedish, it appears that the site where the digital…

  • New World Record Achieved in Solar Cell Technology

    A concentrator solar cell produced by Boeing-Spectrolab has recently achieved a world-record conversion efficiency of 40.7 percent, establishing a new milestone in sunlight-to-electricity performance. This breakthrough may lead to systems with an installation cost of only $3 per watt, producing electricity at a cost of 8-10 cents per kilowatt/hour, making solar electricity a more cost-competitive…
