Aquatic Super Power

Articles like this one in New Scientist sure do make me hopeful... using the ocean's thermal differential to generate power seems so obvious... and of course (as the article says), people have thought of it before... but maybe now there will be the will and economic incentive to overcome the (pretty substantial) technical difficulties and make it happen... I like the way they're planning to produce hydrogen to power vehicles as well. Bye bye oil companies. We won't miss you!
