I think the wonderful thing about Hammerfest Strøm's tidal power generation project is that, unlike wind and solar power, tidal currents are constant and predictable, also with little negative environmental impact. Not much help to those countries without a seacoast, but for those of us in northern foggy climes, where solar energy is of little benefit, hurricane and gale force winds are a constant occurence in stormy winter months and hydroelectrical dams on rivers cause major natural and human disruption, this is an incredible alternative. Besides moonpower is romantic. *BG*

From what I have read so far, the cost per KWH for power from this source was calculated at .05 cents US and this cost was given prior to the benefits of mass production of the units.
