Discovery Project Earth Episodes Season 1    


Discovery Project Earth Home Page

  • Stop The Melt
    Dr. Jason Box, a glacierologist from Ohio State University wants to prevent glaciers from melting by covering them with blankets that will reflect the power of the sun. Jason is convinced that his specially chosen material is resilient enough for Arctic conditions but just how indestructible is it really?

  • Raining Forest
    Following the devastation of Hurricanes Katrina and Rita, thousands of acres of Louisiana mangrove forests were left bare. The huge swath of land presents a perfect proving ground for scientist Mark Hodges' idea to use an aircraft to drop tens of thousands of canisters, each holding a tree seedling to repopulate the forest.

  • MARS Turbine
    Fred Fergussen, a Canadian engineer specializing in airships, has designed a revolutionary wind turbine that will use the constant winds that exist at 1,000 feet above sea level to produce a renewable energy. To pass the test it will need to remain in the sky for 24 hours and provide the necessary energy to power a water purification unit.

  • Shiny Clouds
    John Latham, an atmospheric physicist based at the National Center for Atmospheric Research in Colorado, and Stephen Salter, an Edinburgh University engineer, believe that by changing the size of water droplets in clouds they can increase the clouds ability to reflect the sun and stop global warming. Their vision is to build a flotilla of ships that will roam the world's oceans and seed clouds with minute particulates.

  • Scrubbing The Air Clean
    What if 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? Canadian professor David Keith - the 2006 Canadian Geographic Environmental Scientist of the Year - believes he can with a machine that sucks in ambient air sprays it with sodium hydroxide solution and then expels it as clean air.

  • Ocean Pipes
    Oceans cover 70 percent of our planet and are the most important carbon sink we have, but the phytoplankton that converts carbon dioxide into living matter is dying off from climate change. Dr. Brian von Herzen of the California Institute of Technology will deploy five wave-powered pumps in the rough Hawaiian surf in an attempt to restore this critical natural mixing effect.

  • Space Sunshade
    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. See how the lenses are constructed and the rocket delivery system is tested in this audacious experiment to reduce the planet's warming.

  • Space Solar Power
    We could have a source of never-ending power and, at the same time, reduce our carbon emissions to virtually zero by sending thousands of satellites into space, which will gather energy from the sun and then beam them down to earth as a microwave. Former NASA physicist John Mankins puts his theory into practice.
