The more energy captured, the more energy needed to be provided by the dancers.  Yes, they could make it a very stiff floor, but they would capture very little energy.  So, it becomes a matter of how much extra energy dancers are willing to provide.  It will be hard to balance the two to get maximum return on investment.

jhankwitz, I made a similar comment on a different blog just a while back. Whar we don't know is how much the floor actually deflects, which would be the major way that dancers would observe the energy being captured. If the deflectio is very small, say less than 0.025 inches, or so, probably it would just be taken as a slightly cusioned floor. But if the flex were a lot more, say 0.125 inches, then it would certainly be quite obvious and it would feel like a drag. So what we need is more information. And while it may work very well in dry weather, it is not so clear how the sidewalk would survive in our slushy salty southeastern Michigan winters. Of course, any energy capyture mechanism does need to last a while, so durability really matters.

I agree on wanting to see these examples of new technology in action, Nadine. If these technologies meet their PR promises, they could make some very positive changes. I expect that many of the new technologies we're seeing on the Design News site will find positive real-world applications.

Instead of using a Beetle they should have used one of those old two seater V-dubs, then you could call it a Chia Ghia.  ;-)

Maybe Pheonix Contact is trying to make a point. The use of "Green" for many things that obviously aren't. And some of the hated non-green things have a much smaller footprint over their lifespan than do the "green" things. Green has become a sales buzzword and really means nothing. It is used to push many impractical "technologies" rather than to make a real difference.

 

How many of our supposed "Green" projects are really just an excuse to collect a subsidy, and really have very little "green" benefit?
 Is it really "green" or is it just a way on getting the public to give mw money so I can play with the latest fad???

Dancers would avoid an energy dance floor because it would drain too much of their energy.  Basic Physics states that you can't get something for nothing.  Dancing on this floor would be like jogging on a sandy beach instead of hard pavement.

A different green car from Phoenix Contact

I prefer the Green 1970 El Camino that Phoenix Contact did:

It was at an engineering open house that I went to last year.  It has a nice setup for tailgate partying.  :)

I believe the idea was to reduce environmental pollution. Isn't that what "green" usually refers to? 

Conversion from mechanical-to-electric is an old practice and we see this examplified in car batteries.

Rich, the idea of green car is diluted by green color. Whether it can save energy and minimizes the environmental pollutions? The piezo electric effect (converting mechanical energy to electric) is so common and now a day's such appliances are deployed in public places.

Rich,  Definitely missed a few of these during the Fair.  But definitely remember the VW bug.  Thanks.

Latest Analysis
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
