re: Purest humbug
The U.S. consumes over a hundred times the electrical power Denmark does. Heck, Bulgaria consumes more power than Denmark does. A slightly more robust solution is required.
It would take about 20 of the 100 MW ocean power plants to equal the output of the Diablo Canyon reactor here in California. That does not mean there isn't a place for such ocean power plants, but they can't be the only solution across the U.S.
