Pres. Obama
recently ridiculed persons opposed to his program of depending upon wind energy.
He likened those opponents to believers in a flat earth until Columbus
discovered America.
I point out that when Columbus discovered America he used three wind-powered sailing ships. Wind-powered sailing ships no longer have commercial value. Wind power is used on sailboats for recreational purposes. Essentially all commercial sea transport now uses oil. This is come about through a transition from wind to coal to oil. The reason for the change was to reduce transportation costs.

It appears that Pres. Obama doesn't understand this.
Wind power for ships absolutely has a value and the value is the cost of oil it saves by transporting goods without burning oil. Sail assist technology is reducing the ammount of fuel burned and the ammount of polution produced by the shipping industry.
