Mike at Timmynocky has posted a link about an exciting new development based in Norway which has the potential to supply green electricity by exploiting the chemical differences between salt and freshwater to produce a kind of battery based on the reverse osmosis principles now in use at desalination plants. The technology, if practicable, would be appropriate for most large estuary's worldwide. Lab tests have been run and the project managers are ramping up for full scale tests. Click the title bar or better yet, visit Timmynocky to delve a little deeper. Seems promising, but I am not a scientist or engineer. All opinions will be given space here. Let me hear from you.

Hi Thomas,
Thanks for passing this on.
I have to admit to a bit of self interest when I posted the article.
My boat is moored in a mud creek, just off the Severn Estuary here in the UK.
Proposals have been put forward for erecting a barrage, down stream to take advantage of the large tides and strong tidal streams.
The advantages put forward in favour of the barrage, besides the ‘green’ electricity include the stabilising of the tides and the benefits that would have for leisure boating.
Unfortunately it would also probably have a devastating effect on the wild life.
And that would spoil some of my enjoyment of the area.
I shall be spending tonight on board, looking forward to first light tomorrow morning, as it will coincide with the tide coming back into the creek. And drifting in with it will be our winter resident flock of about forty or fifty Teal.
The exposed mud banks will be alive with Red Shank and Dunlin.
Three young swans, part of last years brood will be hanging around the back of the creek annoying the Mallard and that old Heron might even stop by for breakfast.
In a month or so the Teal will be off as the Shell Duck arrive to breed and there is at least one pair of Curlew who relies on the exposed mud banks to help feed their young.
And then there is the Samphire which grows along the high tide line that helps feed me in late summer.
Ah, I’m getting carried away, I’d best sign off before I get started on the fish, the eels etc.
Best regards
Mike
