[quote="wangi"]What's the story with the compressor?
As I understand the idea, when the installation is finished, the buoys, (which are currently inflated & free floating), will be weighted down & will not float automatically until the tide fills the mini-sub and the displaced air fills all or some of the buoys (selection governed by a valve mechanism). The idea was that at the full moon the complete circle would be inflated, at a new moon only a partial sliver of buoys will rise! The valve turns with each rising/falling tide (the engineering has been one reason for the delay).
PS: Thanks for link to paddling pool info - I think PP was granted. I just hope that we don't need a high fence to protect our windaes from enthuiastic basketballers.
