mostly hype ?

An interesting feat of engineering, but practical ?  The article suggests that these micro windmills could charge a smart device, but doesn't list the power output - possibly nano-watts ?  As stated in other posts;  a small solar cell may be more effective, and more cost-effective.

I was reading this and immediately though of the same wristwatch mechanism.  Even when that mechanism was very effective when the watch was used daily or at least every other day, the evolution towards electronic watches together with the substitution of the power hungry LED display by more efficient LCD made possible and very convenient to use small batteries, eventually reaching or surpassing a full two year duration (albeit at a heavy price in regards to creating very toxic waste!).

Now, the interesting thing here is about the many questions the article does not answer, like effective power, efficiency, construction details and how much power is available per square inch or so of exposed area to the wind, and at which wind velocity.  At first sight it would appear that a good quality solar cell would be more effective, working satisfactorily with any kind of light and not only solar.  This development is undoubtless, very intriging, but it looks more like a technical feat.  I cannot imagine it producing anywhere the power needs of present day phones and other devices.

The Specs

It's very cool, but as always, I have to ask for the specifications.  How much energy can you get out of one of these?

Not obvious

Cabe, the rotation part of the windmill is obvious.  What is not is how the microdevices turn that rotation into electrical energy.  Do you know how these micro mills actually generate electricity?  Are there actual micro generators with windings?

Also, how many birds will be killed by these 'wind turbines'?

It probably requires more energy to manufacture one of these things than it will ever convert from wind during its' life cycle. As for generating nano -watts of power by waving my arms about - I could brobably do that more efficiently by blowing on a small fan. 

I wear an automatic (self winding) watch. That, too , haversts the energy in my natural movements. That technology is about 80 years old.

The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.

For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
