Tidal Turbines

[teacher]

Just read this in the Times. What impact will these tital turbines have on fish?

OpenHydro plans to deploy farms of tidal turbines under the world's oceans that will silently and invisibly generate electricity. The company's open-centre turbine technology allows for the generation of electricity at little cost to the environment and without the turbines needing regular servicing.

Very little in a negative sense, I hope. I'd imagine there'd be screens on the inputs and I guess most fish can swim against the tide so should be able to get clear of them. It's not like they're actively sucking water in, more it flowing throuhg them.

On the plus side, if there was a sort of exclusion zone that kept the commercials away from them, it might create a bit of a haven for fish where anglers could get a look in.

thats a good point about the exclusion zone....hopefully

a lot of work has to be done on these yet
