      ...require people somewhat more "on the ball" that those I've suggested, but if you've got them, capable engineers are definitely a plus for any major energy project. And your suggestions do look intriguing.

      Obviously, I also threw out the above article for anyone who has almost nothing in the way of design or technical expertise -- villagers with limited equipment watching rising seas take their fields... But if you can refine this concept into something more effective, then more power to you.

      And literally, at that.

      ...the Wells turbines in the upper illustration would be subject to ferocious corrosion in the salt air.  Better to isolate them from that by using two large flexible air bladders, one on each side of the turbine, both filled with dehumidified nitrogen or some such.  Thus the air would be "squeezed" from one bladder to the other by wave pressure.  

      The system could be monitored for leaks via an air output line on each side, whereby pressure between the two should always add up to the same figure: if averaged pressure between the respective sides went out of balance, that would indicate an air leak and alert maintenance personnel to change out the bladders with new ones and repair the old ones for future use the next time a swap is needed.
