That 2 cents will go towards buying a filter that will remove the eggs and larva. Then there is boiling/sanitizing by other methods that are much cheaper than a nuclear desalinization plant. There is a lot of really crappy water - parasites, diseases, pollution (biological, chemical, heavy metals, etc), low pH, high pH, crocodiles, hippos, warlords, terrorists, dictators, etc. Nuclear desalinization will not save the world. By the way, where did you those 2 pennies?
