    The world's first air battery (runs off oxygen)

    World's first battery fuelled by air
    The world's first battery fuelled by air - with 10 times the storage capacity of conventional cells - has been unveiled.

    Published: 8:19AM BST 20 May 2009
    Scientists say the revolutionary 'STAIR' (St Andrews Air) battery could now pave the way for a new generation of electric cars, laptops and mobile phones.
    The cells are charged in a traditional way but as power is used or 'discharged' an open mesh section of battery draws in oxygen from the surrounding air.

    This oxygen reacts with a porous carbon component inside the battery, which creates more energy and helps to continually 'charge' the cell as it is being discharged.
    By replacing the traditional chemical constituent, lithium cobalt oxide, with porous carbon and oxygen drawn from the air, the cell is much lighter than current batteries.
    And as the cycle of air helps re-charge the battery as it is used, it has a greater storage capacity than other similar-sized cells and can emit power up to 10 times longer.
    Professor Peter Bruce of the Chemistry Department at the University of St Andrews, said: "The benefits are it's much smaller and lighter so better for transporting small applications.
    "The size is also crucial for anyone trying to develop electric cars as they want to keep weight down as much as possible.
    "Storage is also important in the development of green power. You need to store electricity because wind and solar power is intermittent."

    Global Warming Cure?

    Hey Doc,

    I wonder if the
    porous carbon and oxygen drawn from the air
    would bring about a solution to Global Warming, Climate Change or what ever the flavor of the month (that is the most recent extension) to Ecology.

    Would if irritate Conservatives or Liberals more?

    I believe that solution to Global Warming will be multidinous. It will involve a reduction in total use of carbon-based fuels, recapture of CO2 that is released from use of carbon-based fuels, and less use of energy. The first and the last are beneficial to our country even if less carbon dioxide were to accumulate and contribute less to global warming than anticipated.

    Wise.
