To be fair I have far less problem with Under water turbines than I do with windy ones.
They are out of sight and the tide is far more reliable and predictable to hundreds of years in advance.

The whole Renewables thing seems to be dying a quiet death. Look how the 'The Global Renewable Energy Index' is doing. Not too bad until 2008...  But then...  In the last month...  RENIXX Website said: The RENIXX® (Renewable Energy Industrial Index) World is the first global stock index, which comprises the performance of the world´s 30 largest companies of the renewable energy industry whose weighting in the index is based on the market capitalization (free float).

Very interesting to see the charts, thanks.
Continuing the good news for greens...
What Is Behind The Fall Of Germany’s Green Energy Minister?
Norbert Röttgen, Angela Merkel's Environment Minister, was - until a few hours ago - the face of Germany’s green energy transition. He aligned himself with a goal which can be stated politically, but which cannot be reached technically. His sacking was therefore inevitable. He is the first political victim of the green energy transition but he will almost certainly not be the last.
Peter Heller, Wissenschaft kritisch hinterfragt, 16 May 2012
For the German Chancellor, the green energy transition is probably not something that she does out of conviction. She has - as so often – only adopted a policy in order to neutralize it, to give her opponents no point of attack, no room for distinction and no potential for mobilization. What she needed was a minister who followed this plan in a way that was politically communicable but would not lead to major upheavals in practice. What she got was a man of conviction. No mechanic of power. She got someone who was apparently deeply convinced not only of the need but also of the possibility of a switch to renewable energy sources combined with significant energy savings. Someone who actually thought this would be good for the industrialized nation Germany.

awaits flaming The aforementioned maintenance and replacement budget might be a bit steep for the benefits to be gained but I'm sure the Government will find the money from somewhere - probably a specal tax on gas extraction at some point after it has become the mainstay of energy generation. And they will be a good way to prevent anyone invading us by submarine, so dual purpose. At least in the sea there are no creatures for the propeller things to injure. Oh, hang on though, what about the creatures of the sea. Will they be able to avoid the blades like the birds and the bats do ....?

Einion Yrth said: There goes the 2nd law of thermodynamics again. Not really. Having read the article, the inventor claims that the fan helps with the recharging and is not claiming that it's a perpetual motion machine. Yes, the fan will create drag but of you could gear it to drive a big enough alternator, you could probably extend the range of a small electric car quite a lot. It would in effect be "free" energy like regenerative braking.
