Which contributes more to carbon dioxide pollution -- all the coal-fired power plants in the U.S., or the industrial ships on the world's seas? Answer: the big ships. Clearly, one thing being overlooked in the fight against greenhouse emissions is the shipping industry.
Imagine a big shipping magnet putting his ships under the power of sails. Don't laugh, some ships already are sailboats. How about hulls coated with air bubbles to reduce drag, sleeker bows, and more efficient engines and propellers.
Oh, yes, and how about doing away with ships that leave such a large carbon footprint? Bring on the sailboats; bring on green ethenol; bring on liquid hydrogen.
