    Wind-powered car breaks record: 126.1 mph or 202.9 km/h
    last edited 2009/06/04 08:45 (*)

    A British engineer from Hampshire has broken the world land speed record for a wind-powered vehicle. Richard Jenkins reached 126.1mph (202.9km/h) in his Greenbird car on the dry plains of Ivanpah Lake in Nevada with a wind speed of just 30mph (48km/h).

    So, what's the MPG (miles per gallon) or the Liters (of gasoline) per 100km of that vehicle? Before you come up with some numbers, consider this: the Sun heats the Earth, due different heat storage qualities of the landscape (ocean and land mainly) and the natural green house effect of the atmosphere winds occur, and those drive the vehicle. So - there is an energy usage, yet, none which comes from the planet itself, but from the Sun. So, in this sense, every wind powered device is essentially a sun powered device.

    Shell quits alternative energy investments
    last edited 2009/03/30 19:32 (*)

    According to The Guardian , the UK-based energy company Shell quits wind, solar and hydro power investements - as if it was just too good to be true to have an oil company to metamorph into a "green" company - so we are back in reality, Shell is and was always an oil company and will end as such as well.

    The same week Obama announces to invest more into wind farms and bring US back to leading development in that area of expertise, which in the last 10 years was dominated by europeans. Isn't this odd, one quits, another starts to invest more in the same technology?
