Water-generated power that doesn’t give a dam in Minnesota
From MPR, an interesting little piece on the nation’s first hydrokinetic power station, now under construction in Hastings, Minn. This differs from traditional hydroelectic power, which we have been making for 100 years or so, in that no dam is required, just the natural current of the river, in this case, the mighty Mississippi. Think of it as an underwater wind turbine.
