If one accepts that fish ladders are only "somewhat" successful,
has anyone looked at the potential to wipe out our fish with 
such systems??? -- I am aware that BC Hydro did look carefully 
at this potential about 15-20 years ago, and if I remember 
correctly, it was outside consultants that showed that it was 
costly, and potential environmental downside was huge.

As for the slack times on tidal power systems, BC Hydro has 
large hydro plants now that will generate lots of power for 
short periods, (There is not enough water available to produce 
full output continuously) and can generate much less during 
periods when plants such as tidal plants are running -- in 
effect they can store energy through slack periods. However, 
even with this storage media readilly available, studies, I 
believe, showed that both wind and tidal power were at least an 
order of magnitude more costly than conventional systems.

While I am not a huge fan of Hydro, I believe that they have 
been very effective in their efforts to provide a long term 
source of energy at a low cost. Face it, even at current costs, 
electricity is cheap in BC.
