2.  Tidal power is:  -The us of the rise and all of tides involving very large volumes of water of low heads to generate electric power.  Has potential for generation of very large amounts of electricity, or can be used in smaller scale.  Tidal power is not a new concept and has been used since at least the 11th Century in Britain and France for the milling of grains.

3.  -Barrage at a bay on the gravity of the moon to move tides up and down.  Utilizing the fast flowing marine currents by tides action.

4.  Renewable  Renewable, relies on the gravity of the moon to move tides up or down.

5.  Cannot be depleted like fossil fuels.  Tidal waves are predictable, and this predictability is also one of the advantages that tidal waves gad over other energy sources.

6.  -Variation in tidal range cause the output to not uniformed throughout the day.  -Maintance of machinery is difficult when performed underwater or at sea.  -Tidal fences in order to mitigate fish migration would be maintained.

7.  -Norway  -Ireland  -Canada  -Austrila  -U.S  U.K

8.  A strong economic case for generating electricity using the open center turbine. Currently, the cost of generating electricty using open center turbine is compose to that of offshore wine.
