They should really be looking at the whole Bristol Channel/estuary.

Massive environmental impact and enormous cost. A better alternative
surely are marine turbines. Less impact, less cost, and installable
over a large part of the estuary, as you suggest. But still no leccy
at slack water, the weakness of all tidal systems.

All tidal power is crap because the tides themselves are high entropy.
Ergo massive expensive structures causing huge eco impact to achieve
very little.


Once you look at entropy and energy density, assessing renewable energy
is simple.

And you always get the same answer. Its all crap.

Interesting comment, which I won't claim fully to understand, although
I have an inkling (thermodynamics was never my strong point!). Do you
have a link or book reference that gives a bit more detail, without
being too heavy or theoretical?

That article was an excellent treatise on the madness of anti-nuclear
and pro "renewable" energy policies currently being pursued in the UK,
Europe and America.

I've downloaded it for future reference, it was _that_ good. My
thanks to you for providing that link.
