I think those could also be called art - they're cool looking and, I think, add some visual appeal to the building.

Notice the lights that shine on the turbines at night from below. Looks pretty but will consume power.

Years ago a company was going to build a highrise in a urban area NY city if I remember correctly and for mostly for style they were going to have the building sitting on pillars leaving pedestrian traffic unimpeded across the property but wind tunnel tests showed that on breezy days the wind going under the building would be at hurricane force. The building went up without the plaza. The point being that if instead of making the wind farm an afterthought you design the building around it you could achieve a much greater energy output without affecting the practicality of the building.

Bahrain World Trade Center has some MW turbines integrated.

wow, no talk about off grid

re; Eric Malatji
To go off grid you have to produce power equal to use The press release states that this is not so.

Looks like a bizarre mutant barber shop. More show than go, I would suggest.

How about the Pearl River Tower in China ? It is almost self sufficient in its energy needs.

Sadly another scam as these vertical wind turbines as all other VAWT's can't because of basic physics every be cost effective because they put out little power/$ or lb.
So far only 2-5 blade normal HAWT's have a shot at cost effectiveness and even then they have to be really good.
If RE is going to be big, and it will because when done right is already the cheapest electric source for homes, buildings making their own, we are going to have to weed these scammers like this company out and even put them in jail for fraud as it's just stealing by a different name.
