Hi All Andrew is worried about salt and wants some costs.
The salt weight we put up to offset double CO2 is about 1% of what is thrown up by waves breaking, much of which is at the beach and will fall on land. It is this which keeps the ocean salinity so constant. The only thing about our spray is that the diameter is ideal for condensation nuclei. Victorian doctors knew that sea air was good for invalids. Polish doctors noticed that people working in salt mines hardly ever had any lung disease. Asthmatic children get cured for two years by deep breathing exercises in salt mines. My guess is that the bugs are being killed by osmosis. Check out http://www.thesaltpipe.co.uk/ If the cooling to spray-rate calculation I gave in the Phil Trans paper works for water flowing to the Arctic we need six months operation of a fleet of about 50 vessels of 300 tonnes displacement and 150 kW plant rating costing £1 or £2 million each to remove the latent heat corresponding to one season's missing ice. They can go off to reduce hurricanes for the other six months.
