The oceans that provide bookends for North America offer almost unlimited supplies of energy related to the movement of water. Many demonstration generating projects are on the way. These resources raise jurisdictional questions and logistical challenges.

  • Salt water weights approximately 68 lbs per cubic foot. An oceanic waves just 3 feet high by 6 at the base 100 feet long should weight approximaly 61,200 pounds. If we multiply that by the thousands of waves in the sea, the overall weight pull of the moon on planet earth's surface or its oceans is mammoth. A person weighing 180 lbs. disperses about 1.77 cubic feet of water verses about 900 cubic feet of water in such a wave. Should we not be floating on air at a weight of just 180 pounds?
