The scientists proposal of using cloud ships to launch clouds into the sky via 1,900 unmanned wind-powered ships criss-crossing the oceans, sucking up sea water and spraying it from the top of tall funnels to create vast white clouds was interesting. The Copenhagen Consensus Center estimates that it will only cost US$9 billion to launch in the next 25 years, compared to the US $250 billion that many countries plan to spend on climate change every year. It's mind boggling, really. The question is, will it work?
