Cleaning sea water is expensive
Not particularly. Desalination costs about 65¢ Australian per cubic metre (that's about 43¢ US)
Burned carbon cannot be recycled.
Yes, it can. For about $1.40US a gallon operating cost, in 2007, if you're making gasoline from it; Rather less if you make methanol. That is, according to
the paper I have linked several times in these discussions.
Nuclear has pollution problems too
Does it? Could you be more specific about these "pollution problems"?
Nuclear power is the only industry in history that completely manages its waste stream; In normal operation, nuclear power plants produce zero pollution - unless you want to count the exhaust from the workers' vehicles.
your rose colored view of the future is starting to get annoying
I don't have a "rose colored view of the future". I fully expect humanity to fuck it up massively.
Where we differ is that I recognise that all of the technological advances required to avoid this are already made; Our problem isn't that we don't have a way to stop the damage, or a way to fix the damage; Our problem is that the world is full of adherents to the appeal to nature fallacy, who are hell-bent on preventing any actually effective solutions from being implemented. Apparently for no better reason than that they require technology. And technology is bad. And scary.
Pretending that we can fix the problems with windmills and sunshine is beyond fucking stupid, and requires an incredible ignorance of the scale and nature of the problems we face.
But politicians are so scared of the effect the N word has on their popularity, thst they will do anything rather than face up to the fact that nuclear power is by far and away the best solution to almost all of the environmental problems we face.
Seventy years of propaganda is remarkably effective.
The single person most responsible for environmental degradation in history is probably Jane Fonda; Certainly her actions have caused millions of unnecessary deaths.
