First Commercial Sub-Sea Tidal Power Station
daksis writes "New Scientist is reporting that the first commercial sub-sea tidal power station has gone online in Hammerfest Norway. 'The power station, which resembles an underwater windmill, began generating electricity for the town of Hammerfest. Although still largely a prototype, the generator is the first in the world to harness the power of the sea and be connected to an electricity grid.' If they can make the technology commercially viable, then we'll have yet another weapon in the arsenal for producing cleaner energy."
10 meter blades that they have are spinning quite slowly - I'm sure the fish could easily swim out of the way. I'm sure they also wanted to avoid seaweed and have some sort of filter/fence to prevent stuff from clogging up the blade.
