Watch as some of the world's leading scientists put the most ambitious geo-engineering ideas to the test in order to tackle global climate change. From covering acres of Greenland's glaciers in protective blankets to constructing space rockets to sending tiny reflective lenses into orbit, these experiments push the boundaries of science and technology by exploring eight creative ideas that just might reduce global warming.   

Could humanity have a source of never-ending electricity and, at the same time, reduce carbon emissions to virtually zero? This is the astonishing vision of former NASA physicist John Mankins. His plan is to send thousands of satellites into space, which would gather solar energy and beam it down to Earth as microwave energy. The microwave energy would be collected by antennas on the ground and then converted to electricity. Can Mankins make this all work?
