The synopsis:
Five of the world's top scientists propose five radical scientific inventions which could stop global warming dead in its tracks. The ideas include: a giant sunshade in space to filter out the sun's rays and help cool us down; forests of artificial trees that would breath in carbon dioxide and stop the green house effect and a fleet futuristic yachts that will shoot salt water into the clouds thickening them and cooling the planet.

The sunshade was great, he wanted to put 16 trillion mirrors (each 2ft across with onboard positioning computer and they would have to weigh only 1g) between the earth and the sun, the cost was something like 4x the US GDP and they would have to build a giant electromagnet powered cannon inside a mountain to launch each module of 1m mirrors! now that’s blue sky thinking
