I had a similar thought, but kept it to myself..... looks like a monument to the French Tickler!

This has to be one of the dumbest things I have ever seen, in any number of ways.  I am beyond words, so I'll leave it at that.

ONLY IN SWEDEN would somebody come up with this. Just consider the logistic challenges of collecting the power generated that way. And the comments about dirt collection are certainly valid as well. In addition the thing looks sort of obscene.

That last point is a great observation!

Not only is this ugly, but it will be an ugly duster. Is this area prone to any siesmic activity? Nothing like shaking the dust off the duster (especially if the duster is the size of a building) to create a photogenic moment.

@cwoodhouse, I agree, the windows wouldn't take long to become opaque, and materials wise, the covering would soon start shedding like a puppy.

@Ratsky - If only it happening, we'd actually do something about it. I like your point about wind energy and I believe Chicago can serve as a good starting point for a venture of this nature.

Wind load and other issues
eafpres   5/31/2013 1:43:49 PM
Along with the already mentioned issues of abrasion, ice, and questionable power output, I add:

a) The conversion of wind energy to electrical in PZ devices is relatively good, The overall efficiency would include the effectiveness of coupling wind into movement of the devices to generate force on the PZ materials.  My guess is that compared to, say, 80% overall efficiency for a good wind turbine, this will be much, much lower.

b) If somehow a very high coupling of wind into mechanical force were acheived, then it would signficantly add to the wind load of the building, requiring heavier construction.  This would need to be accounted for in a total life cost calculation.

c) Most tall buildings require regular washing.  The fact is, there is a lot of dust and it settles on the vertical surfaces (windows) and must be washed off.  This thing will attract dust like crazy, and will be very difficult to clean.

"There is so much wind energy to be harvested in cities...."  That reminds me: Chicago is known as the "Windy City" not because of its climate, but because of its politicians!  THAT is the real energy that needs to be harnessed.

a.saji, I've noticed that industrial design and, to a somewhat lesser extent, civic design, doesn't always follow good artistic principles. On the very small scale, my commercial-grade dehumidifier does a great job, but since it was designed for maintenance operations of a business, no thought was given to making it look nice, and it's really ugly. OTOH, it sure gets the job done, unlike the pretty but relatively useless dehumidifiers designed for people's homes. My point is that design esthetics are often not considered, especially when coming up with new technologies and/or using new materials for existing uses. I can understand all that from the POV of limited budgets and/or development time. I only hope that a later rev will take esthetic concerns under consideration.

Good point, Constitution Man!  Being from Southern California, I completely forgot about the possible effects of ice!
