All they basically do is delay the tide a few hours in and out. http://www.severntidal.com/info.html The small difference in level also facilitates the safe passage of salmon and other fish species through the special turbines, something that is not possible with conventional turbines with their high pressure drop and sharp edged high-speed runners (rotors). There is nothing to suggest that there should be any more risk (possibly less) from a salmon passing through a turbine than from ascending a natural obstacle of similar height in a river such as a set of rapids, with sharp rocks and high turbulence. |
i dont fear for the adult fishes, but those places are most of the time the ground where fish lay down their eggs..
if its safe, hell yeah, bring it. but till then, we shouldnt risks to much. marine wildlife is allreay massivly under presure.

There are fears on wildlife for the electro magnetic fields that wind turbines create though. Also whether the vibrations that they create also do any harm. We don't really know a lot about any of it at the moment.
But to me Tidal does potentially look like the least disruptive and most reliable source of renewable energy. :)

the electro magnetic field does nothing to animals or humans, thats just a trick argument of stupid people who dont like windturbines. same goes for infrasonic waves. the only real problem are birds that get killed. but those numbers will go down over time because birds will adept.
but im against wind in the german and danish northsea too, thats one of the most important region for young fish, and other sealife and we shouldnt build huge buildings into the mud.
