As a sailor and one-time worker in GE Power Generation, I have always marveled at our inability to harness the power of the seas. It looks like technology is finally getting to the point where we may see it happen. I have seen predictive articles for years, but this one http://www.popsci.com/science/article/2013-05/future-energy-water shows some real promise and commitment. Imagine, unobtrusive, to us at least, power generation equal to 1/3 total US energy usage from the tides – no dams, no fights over views, no waste. Time will tell what environmental impact studies will say about how these interact with fish and other sub-sea creatures, but it is very promising on the surface (literally!).
