24/7 production,

Only notionally. It varies with the tides and peak production may not be
when you need it.


I'll pick you up on that one (only). Tides around the UK are such that
you can always be making tidal power _somewhere_ regardless of the state
of the tide. Of course, you do have to cost in the grid to move it
around, and overcapacity so you still have enough at neaps - but I think
it may have a place.

I was specifically addressing DD's suggestion that the entire power supply
for the UK could be derived from tidal power in the Irish Sea. I agree that
distributed systems around the UK would alleviate the problem, but I think a
lot of work still needs to be done on the effects of the lagoons on marine
environments.
