Ideas to Cool the Earth

Visit Discovery: Project Earth which promotes its newest series Fridays, starting Aug. 22 at 9 p.m. ET/PT. "See what happens when "what if?" meets "why not?" Discovery Project Earth re-engineers the planet's possibilities and literally spans the globe, pinpointing areas of both concern and opportunity in confronting climate change."
Ideas include:
Dr. Jason Box, a glaciologist from Ohio State University, wants to prevent glaciers from melting by covering them with blankets that will reflect the powerful rays of the sun.
Scientist Mark Hodges believes he has devised a way to reforest large areas of Earth from the air by using an aircraft to drop tens of thousands of canisters, each holding a tree seedling.
Atmospheric physicist John Latham thinks that by changing the size of water droplets in a cloud they can increase the cloud's ability to reflect the sun and stop global warming.
Canadian engineer, Fred Ferguson, has designed a revolutionary wind turbine that will use the constant winds that exist at 1,000 feet above sea level to produce energy.
Astronomer and professor Roger Angel thinks he can diffract the power of the sun by placing trillions of lenses in space and creating a 100,000-square-mile sunshade.
NASA physicist John Mankins plans to send thousands of satellites into space, which will gather energy from the sun and then beam the solar energy down to Earth as microwave energy.
Canadian professor David Keith believes we could solve the problem of global warming by just scrubbing the air clean of carbon dioxide, before it has the opportunity to add to the blanket of greenhouse gases smothering the earth.
