mapsontheweb:Global Tidal RangeThis map shows the patterns of tidal energy played out acrossthe surface of the Earth as lines of force. The colors indicate wheretides are strongest, with blues being weaker areas and reds beingstronger. In almost a dozen places on this map the lines appear toconverge, as if pulled together like a purse. Notice how at each ofthese places the surrounding color–the tidal force for that region–isblue. These convergent areas are called amphidromes, places wherethere is little or no apparent tide. This is not to say that the surface of the ocean in theseplaces doesn’t move, doesn’t rise and fall with wind, momentum,inertia, and other forces acting on it. But for the purposes of studyingthe tides from space in an effort to understand how energy is conservedand distributed, these areas a mathematically still.… and where you have that good tidal action, you can build tidal lagoons and barrages (which can incidentally be people-amenities while they do their main thing of generating an inexhaustible supply of clean energy. Swansea tidal lagoon is projected to have output greater than the consumption of the city. That’s a small city, but still a respectable amount of energy.) -- source link
