THAT'S THE SPIRIT!
If it would ever get off the ground, it would become massive and make the creators TONS of $$$$$$$$$$$!
IF they could get the damn treehuggers outta the way. They'd probably say something lame like, "The surf generators are causing shorelines to not be eroded naturally and the fish are being pounded TO DEATH!! YAAAGGGHHH! DAMN CAPITALIST BAAAAASTARDS!!!"
Check out what the French have been doing with tidal generations without a peep from the envirno-nuts:
"Tidal energy traditionally involves erecting a dam across the opening to a tidal basin. The dam includes a sluice that is opened to allow the tide to flow into the basin; the sluice is then closed, and as the sea level drops, traditional hydropower technologies can be used to generate electricity from the elevated water in the basin. Some researchers are also trying to extract energy directly from tidal flow streams.
The energy potential of tidal basins is large — the largest facility, the La Rance station in France, generates 240 megawatts of power. France is the only country that successfully uses this power source. French engineers have noted that if the use of tidal power on a global level was brought to high enough levels, the Earth would slow its rotation by 24 hours every 2,000 years."
