21. There are tidal streams , eddies, races and heavy overfalls both in the east and west flowing streams of the tide. 22. The tidal range in this area may exceed 40 feet while tidal streams may run at more than seven knots. 23. All tidal stream turbines constantly need to face at the correct angle to the water stream in order to operate. 24. Tidal stream generators are the cheapest and the least ecologically damaging among the three main forms of tidal power generation.25. The bridge could produce 200 MW of renewable energy from a tidal stream system, enough to power over 400, 000 homes. 26. Inshore hazards include the strong tidal stream around Godrevy Island and the tidal current at the mouth of the River Hayle. 27. In March 2008, the construction of the world's first commercial tidal stream turbine, for Marine Current Turbines, was completed at the Belfast yard. 28. Cavitation has also become a concern in the renewable energy sector as it may occur on the blade surface of tidal stream turbines. 29. The tidal stream is going to be there and it is going to be exactly the same, you can predict it at all times, 30. It may be associated with the Monoceros Ring a long tidal stream of stars that could have been formed from a disrupted dwarf galaxy.
