They braved the harsh conditions in the middle of the night to set up a
large searchlight with specially designed reflecting optics to
generate a gigantic light sheet next to the 130 - meter - tall
wind turbine for illuminating the snow particles in a 36 - meter - wide - by -36-meter-high area.

Atmospheric science professors Nate Brunsell and David Mechem in KU's Department of Geography are co-authors of a new study just published in the Proceedings of the National Academy of Sciences by an international research group that evaluated the effects of
large wind farms on atmospheric flow and its implications for how much renewable energy the
turbines can
generate.
I think that in a sustainable energy economy of the future, most electricity will be
generated, stored and used locally, and
large centralized
generating stations (which by then will be predominantly
wind turbine farms and concentrating solar thermal power plants, coal and nuclear having been phased out) will play a much smaller role.
The country's
largest wind farm to date is expected to start producing power this summer; the total of 54
wind turbines due to be installed by 2010 will be able to
generate up to 135MW.
The technology, which EnviroMission calls a Solar Tower power station, uses the sun's heat to warm a
large body of air which then rises through a vertical
wind tunnel causing
large turbines to spin and
generate electricity.
This is not surprising, since a
large, advanced design
wind turbine can
generate $ 300,000 worth of electricity in a year.
And because they are now 100 meters tall, instead of less than 40 meters, they harvest a far
larger, stronger, and more reliable
wind regime,
generating 20 times as much electricity as the
turbines installed in the early 1980s when modern
wind power development began.
Another option is to install of the small
wind turbines (like a Air X) and use it to see how much power a
larger wind turbine would
generate.
Although small
wind turbines may look like miniature versions of
large turbines, there are important differences in technology, purchase decisions, application requirements and value of
generated electricity.
Based on
wind - speed measurements, researchers at MIT, led by Stephen Connors, director of the Analysis Group for Regional Electricity Alternatives, calculated that
large turbines located far offshore could ultimately cost less per power
generated than either land - based
turbines or near - offshore ones, even factoring in extra costs, such as much longer underground electricity transmission cables.
