We all now chortle about the flying cars that always seem to be just out of reach and not all that likely, but it is still fun and interesting to see a new idea that really floors one that seems somewhat plausible.   There is a real nugget of information that was an eye opener to me and I test asked a dozen really smart people and no one have a clue:   More than 1/2 of all seafood used by humanity comes from less than .1% of the entire ocean area that is naturally fertilized.   Moreover  a scientist-entrepreneur named Russ George has experimented with incredible results distributing iron sulfate into previously barren offshore water  and tripled his catch of salmon in one year.     Once I read the book I will put up a review, but I thought it worth sharing for now.    This sounds better than blasting off into space!!   Rick
