I have seen this years ago on the bottom of the Hudson River in New York, where it was for a super-market, the first one broke of, that is how strong the current of the Hudson River was, I remember it snapped the wings right off!
Does any one either know about this or worked with this system especially in big rivers and currents like oceans and tidal wave energy comes to mind?
We have never worked on such systems, but I can shed a little light on the subject. The process is called “Hydroelectricity” the production of electricity through the falling or flowing of water. Dams, run of the river or tide are all examples of generating electricity through water flow. Remember electricity is produced by magnetic induction, in a nut shell, magnets being turned around coiled wire, a “dynamo”. Something has to turn the dynamo. In the case of a small home generator a gas engine turns the dynamo. In the case of some large power plants they use Dams to harness massive water pressure to turn the dynamos. Under water turbines are nothing more than aquatic propellers, using the rivers water flow pressure to turn, thus turning the dynamos to produce electricity. On good thing about tide power is that you don’t need to create dams. Dams can often hurt the environment when the lake is created behind them.
P.S. The good old “Water Wheel” on some farms is yet another example of generating electricity from the flow of water.
