Tidal power, finally!

This is exciting news: tidal turbines may be leaving the experimental phase and heading to production soon. Those dreams of offshore tidal-powered data centers and powerhouses for the (stormy) world are a step closer to reality.

Offshore power has always been a challenge - thanks to the harsh marine weather conditions. It is certainly exciting to see a first turbine pass the tests, but also leaves some interesting questions open: are such turbines compatible with marine ecosystems, or will we be eliminating too much wildlife along the way? What is the life span and maintenance costs of such a generator, and will it be able to recoup its costs without government subsidies? How can these generators be most effectively tethered to the powwer grid?
