Birds may be alerted or warned with ultrasonic sounds or possible microwave chirps in license free bands. (Feathers act as antenna is a known fact) So Wind Power can be done safely when moving. Subject to local testing & verification. (ask me if consultant needed)
In recent months the Wall Street Journal has reported that the bird kill count due to wind power machines was on the order of 444,000. Although this swaps the bird kills due to oil drilling, the Justice Department has started a law suit against several oil compainies over the matter of less than 30 bird kills. Any bird kills are regretable, but these reports and actions have provided a little perspective on wind power generation, whether backed by batteries or ultra capacitors.
FWIW, I think the article does a very poor job of explaining that the ultra caps are being used in the pitch control system. In fact, I find nothing that actually says so!
Being a bit on the suspicious side, I wonder if it deliberately gives the (false) impression that they are being used for load leveling.
I admit to being curious about this technology, but have so far been put off experimenting by the cost.
If I understand this right, the grid senses and adjusts to power potential on any part of the grid (automatically or manually). Since batteries tend to "trickle" out their power over time, it is harder to absorb this into the grid fast enough to prevent battery overcharging. (when there is a lot of wind) Capaciters give enough time to absorb the extra power potential at a higher rate and timely manner so very little is lost from a high wind period.
The article stated that the capacitors are used for supplying power to the blade pitch control mechanism, and it explained the advantages of using them there (longer life, more charging cycles, quick response to load, etc.). It didn't say that capacitors were being touted for large scale energy storage.
Ultracapacitors are in fact a storage device, yet no one is claiming to try to use them for 1Mwhr, because they are not cost competitive for such large energy requirements, as you have pointed out.
For those such applications, lead is, and will be the less expensive option, beating even lithium ion.
However, when you look at power requirements, how well do those lead acid batteries cycle?
If you were to use the lead acid option for such a large installation where there are cycle requirements,
you would replace the lead acid semi-annually.
In high cycle applications, such as wind turbine pitch control and hybrid buses, ultracapacitors are replacing lead acid and other battery technologies at a rapid pace. The demand for ultracapacitors is growing globally from a number of different applications, while the market is general has a CAGR of 42%. There is a reason that the market is growing,
and it is not because of "scammers". It is because ultracapacitors are being used to replace the
True, ultracaps aren't an economic solution just yet, but the technology may grow in time. When I was in college we were told "you'll never see a 1F capacitor because it would be as big as this room."
So much bull here. UC's are extremely expensive and almost useless in real life. The only ones pushing them are those trying to scam money/grants from others.
To show the point would the author please cost out a 1 Mwhr UC storage array and contrast it with an identical lead battery version. Please include all nessasary power electronics to make a 0-2.7vdc/cell work?
Next cost out a 12vdc 100 ampr UC storage unit with nessasary electronics, Lead is $60/kwhr for comparison I buy all the time.
Until you can do that your post is a bad joke. Please prove me wrong?
Now add the fact the grid demand is far more variable than even wind. And they handle that fine. 5+ different battery type can now do storage for under $10/kwhr/yr or under $100/kwhr. Yet rarely are these already for prime time batteries use in grid storage, Why?
UC's have some utility in electronics, inverters, etc but as for storage, not a chance. Why was this article allowed here?
A new battery design, which replaces lithium with abundant and low-cost elemental sulfur, is still in its nascent stages but shows real promise for giving batteries more energy potential.
PTC will offer a virtual desktop environment for its Creo product design applications, potentially freeing engineers to run them from remote desktops on a variety of operating systems and mobile devices.
The push to achieving more intelligent, integrated manufacturing is putting a strong focus on networking and connectivity as key enabling technologies.
Now that solar and wind harvesting technologies are a thriving market, researchers are seeking other environmentally related energy sources for which they can create harvesting devices.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
