Libyan climate change initiative

Gaddafi would be proud of this idea - maybe a good follow up on his Great Manmade River project -

15km diameter greenhouses in the desert with a central 'chimney' vent to create a steady inward wind around its circumference and surrounded in turn by rings of wind turbines. Sounds interesting but is it credible?

A scientist named Muftah Elarbash, leading the Libyan Initiative at the Conference of the Parties (COP17) meet at Durban, claims that his country has already prepared the "draft engineering" to cut carbon dioxide emissions down to zero by 2021.

Presenting his proposal at the COP17 meet, Elarbash said his scheme is to harness solar energy from the Sahara and the Arabian deserts to create "permanent low-pressure zones", which would trigger continuous winds to generate zero-carbon electricity.

He proposes to develop ten 300-gigawatt low-pressure zone plants each year, between 2014 and 2021. According to him, a total of 71 such plants would in essence phase out carbon fuel completely and "achieve zero CO2 emissions."

As for the cost, Elarbash said zero carbon emissions by 2021 would cost $20 trillion in a best-case scenario -- that of halving emissions by 2050, as proposed by climate control negotiations, which would still cost $45 trillion.

lived in a desert for a few months. was calm up to about 2 or 3 each day then the wind would start blowing from the amount of hot air rising, i can see that there would be huge potential energy in these winds.

This idea does not depend on atmospheric wind - as long as the sun shines an artificial wind would be generated as a result of the temperature difference between the covered greenhouse area and the surrounding land - thermal rising of air through the vents creates low pressure at the centre of the installation. The proposers claim very significant power output in a reliable and predictable form.

Or why not just make solar panels ? Or aim lenses at boilers to make steam like that project in Spain ?

Dont know - what power output would you get from an equivalent area of panels or solar furnace?

Maybe the Libyan just love grandiose projects.
