| 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.
