OT Osmotic power

Came across this. Free energy.

Ironic that some of the Gulf States use reverse osmosis for desalination.

But see this, from early last year:

Seemed like a good idea. A potential renewable energy source that would be reliable, consistent and capable of supplying some base load, unlike most renewable energy sources. Presumably just too expensive to implement.

The technology shouldn't be so very different to that of water desalination by reverse osmosis. In fact the chap who did much of the early research in that field, Sidney Loeb, worked on both technologies in Israel in the 1970's

. Israel now has the largest reverse-osmosis desalination plant in the world, at Hadera, producing 127 million m^3 of water, p.a. and scroll down to Israel, about half way down.

It was on BBC 'Coast' yesterday. But Alice Roberts presented the program from Norway, so it must be a fairly old repeat - she's been gone a while.

or

About 4 min 30 secs from the start. Doesn't show the pilot plant though, just a little model (oh, and a swollen egg!).

Pity they've not been able to follow it through. There you are Harry, even 'free energy' isn't free.
