Saw one of these on Orkney this summer. Needless to say, even with a pretty stiff breeze coming in from the sea, which was turning the several normal small scale turbines in the fields, this model was doing literally nothing.

For an extra 50.00
  You can get one that produces electricity if you run it in conjunction with a pair of 250watt PV panels.
 Immediate payment up front is appreciated and they are open for orders which will be available on the next delivery date

It looks like it has been sawn out of a plastic garden chair or a cunning new design of ski drag lift system.

That pic is ringing bells. I'm sure I've seen it in the news, maybe a year or so back, it won some sort of award, competition, maybe students, can't quite remember, but I do recall it was about the size of a basketball and just a demo, and would need to be a 'tad' bigger?

I think the award was for addressing a problem / challenge or something, I don't think it was for proving the generation, it was early days then.

Nope - I'm talking ball cocks, here is the article, and they look entirely different, with or without my glasses.  Embarrassed

Inventors of spinning wind turbine win James Dyson award

Quote
A spinning turbine that can capture wind travelling in any direction and could transform how consumers generate electricity in cities has won its inventors a prestigious international award and 30,000 prize.

Nicolas Orellana, 36, and Yaseen Noorani, 24, MSc students at Lancaster University, scooped the James Dyson award for their O-Wind Turbine, which in a technological first takes advantage of both horizontal and vertical winds without requiring steering.

I see in the detail on ebag that the rated wind speed is 12mtr per second ( about 25mph) and the braking speed is 13 mtr per Sec.  Which leads me to think that this is not going to make much leccy for anyone or ever pay fot itself BUT 3 cheers for the advertisers honesty.

Not quite Andy.  It brakes itself when the wind speed reaches 13m/s.  It says safe to 45m/s.  Presumably the more windy it is, above 13m/s, more braking is produced with any excess power?

BUT that is an awful lot of energy to be harvested from about a 1/4 of a square metre!  A 200m diameter wind turbine has a swept area of 31,000 m^2.  They should be capable of c.120MW, at the same efficiency! Smiley

Remember the old days.
      When a certain Turkish turbine seller and his apprentice, posted pics on Eblag. The pics were of his assembly line in Ankara. The apprentice had a cordless drill in his hand and nothing else in view but a couple of rows of 6 turbine Alts all ready to be exported to Europe where we were waiting with handfuls of money.
The feedbacks made hilarious reading. I think a certain German manufacturer has been his new address for a few years.
