Since I only pay for 1/2 hour a day and I have
not used that ever, I don't get your point.

Oh, I am sorry, I must be to stupid to understand
a system where you pump water up a hill to a resevoir
and then let it drop back through a turbine = electricity.
Gosh, that technology is so inovative I just can't believe
it.  

Actually I was expecting something a bit more creative.
like maybe you had some new type of capaciter that could 
store the power for the short term.

With these three groups backing you why do you have the

Well you don't know much about shipping do you.  All 
these passes are used for boat traffic, they are also
dangerous at full flood or full ebb.  Add any more 
obstructions and they just become more dangerous.  
Good job, save a salmon kill a sailer.

Right.  Add a tidal fence and you make the inlet 
more dangerous to boats.
