… there are still large hurdles to overcome before tidal energy can be adopted more widely, such as dealing with regulatory issues, potential environmental effects and conflicts with other ocean users.

I was wondering about that. What happens to the weather, animal habitats, and everything if you slow tides and currents with a larger number of these things? Still gotta be better than burning fossil fuels.

It’s very hard to take what is essentially a wind turbine normally found on land and put it under water, said Fraser Johnson, operations and maintenance manager at MeyGen. The record-setting turbine should keep going for at least another year before it needs to come out of the water for maintenance, he added.

With a sample size of ONE (okay, maybe four) that projection seems optimistic, but I’m hoping he’s correct.
