Inspired in part by jebatty's Modest Proposal in the Ashcan (yeah, you really do have to act on your beliefs), I'm asking for suggestions about where to go for good information on the latest technology for using the tides to produce electricty. I live on a tidal river and I'm really thinking about the possibility of a local municipal power company involving the four towns that border the river. Tidal power was harnessed in this part of Maine as early as the 1600's to run sawmills and grist mills. The possibility of using tidal energy to produce electricity on a relatively small local level, seems to me to be closer to green, renewable base load electricity production than any other alternative. The massive tidal project proposed (and actually begun) in the 1930's (Quoddy/Dickey-Lincoln) for northern Maine, New Brunswick/Nova Scotia was to be the TVA of the north. According to legend at least, it was scuttled by intense pressure from Eastern coal and oil interests. The concept of tidal power was brilliant in 1930 and remains so today. Smaller local utilization seems to me a real possibility.
