to burn hydrogen produced by stationary wind turbines ashore is an ingenious

obvious question is if the wind can produce electricity that can be used to
produce hydrogen, which can then be burned to achieve propulsion, all through a
series of expensive machines, why can’t a mast and a sail produce the same
answer is simple, though two-fold. Even modern technology can’t produce masts
and sails the size necessary to propel large vessels, and the cost of labor in
today’s market make the operation of a sailing freighter or tanker commercially
aside the pollution caused by the production of the complex machinery necessary
to utilize this energy source, the use of wind to create hydrogen could allow
very large vessels, even those approaching the present 500,000-ton limits, to carry
commercially practical quantities of cargo with little or no pollution. That’s
something the “direct harvesting of wind” can’t do. But the cost of the
technology would inevitably drive up the cost of transportation, and some
people would die from the rising cost of food. (Even today, most of the world’s
basic food stocks are carried on ships rather than grown locally.) However,
we’ll all die later from pollution and global warming unless something is done.
