From wiki - cause that was the easiest place to find the tornado info on BF....

I used to go on "girl trips" to Europe with the woman who is a Sr VP for TVA. She oversees the water levels of the entire system. She does everything she can to avoid cameras or publicity events.... people can get really irate about the water levels on the lakes. She doesn't want anyone to know who she is.
One of my favorite subjects, water power Take a trip up the New Hampshire and Maine coast line. Our area is just the begining of the Bay of Fundy and when the tide goes in and out twice a day in some areas the tide receeds for a few miles. Dependable, there are 3-4 other places in the world where the land configuration has this power.
There it sits, right in front of our face and those that wish to harness the power that is free do not do so. Too much compartition from big business would loose too much money were this power be converted to electricity.
Up north in Maine it is awesome to see docks built a story or so above the mud flats. When the tide turns the water comes in faster then a horse can run, When the tide goes out I found that I have been grounded on the mud flats faster the I can paddle or sail.
The amazing power of the tides and what the Moon phases that control the tide------ properly built just a few plants to utilize the tide would and could light up most of the East Coast for pennys on the dollar.
The tides have more power then any 30 nuclear plants and are dependable to work 24/7 twice a day.
I was raised on the river that has a bridge that Sparky must cross to get home, when the tide is out it is way out, when the tide turns in one hour the water line can be be up 6-8 feet or more, depending on the Moon. here, up North the tide raises 10 feet or more .
