I'm sorry, but I didn't see the point of all of this. What is the use? No pollution for an hour? Or just another facet of the global warming hype? It still isn't sure what causes climate change, and if they are right about the carbondyoxide theory, do you really think we can undo the damage done in a lot of decades? The best thing we can do overall is to start using durable energysources, and prepare for the consequency's of climate change. Those are the onliest options.
