100,000 sq mile Sunshade to Stop Global Warming?

Posted on Sunday, March 1, 2009 posted by posted by Mak @ 8:09 PM

A giant 'sunshade' consisting of trillions of mirrors fired into space to reflect the sun's rays could be the answer to global warming. That's according to astronomer Dr Roger Angel from the University of Arizona, who claims the method is "guaranteed to work".A cannon with a barrel measuring a massive 0.6 miles across would be needed to shoot the mirrors one million miles above Earth – not to mention some £244trillion to fund the project.And, being 100 times more powerful than conventional weapons, the gun would require an exclusion zone of "several miles", reports the Telegraph.

but there was no oil Then, from algae came oil.

This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
