Because the Earth's tides are ultimately due to gravitational interaction with the Moon and Sun and the Earth's rotation, tidal power is practically inexhaustible and classified as a renewable energy resource. Movement of tides causes a loss of mechanical energy in the Earth–Moon system: this is a result of pumping of water through natural restrictions around coastlines and consequent viscous dissipation at the seabed and in turbulence. This loss of energy has caused the rotation of the Earth to slow in the 4.5 billion years since its formation. During the last 620 million years the period of rotation of the earth (length of a day) has increased from 21.9 hours to 24 hours; in this period the Earth has lost 17% of its rotational energy. While tidal power will take additional energy from the system, the effect] is negligible and would only be noticed over millions of years.
PS: Powerbouys utilize "wave" power as opposed to "tidal" power.
Was he aware of the pending LOK news?
No commercial wave power plants have been built yet, but there are roughly 100 concepts for their realization. "Less than ten of these will reach the market within three years," Etter predicts. That’s because making a new form of energy feasible on a large scale is a very complex undertaking.
Since ocean waves are caused by wind, you have your good locations and your bad locations. Where are the wind farms in your neighborhood? Now, when are you going to start making any sense of this?
I gained 35% on the last run. There's big money to be made here if you play it right. Still watching on this run.
