The folks at ITT were showing off their wire rope isolator technology. What’s depicted here (which really requires video rather than a still image) is that the bucket of ball bearings and other stuff that was mounted directly to the vibrating table was bouncing all over the place (the right side of the image). The bucket to the left, containing the same items, had the wire rope isolator between the bucket and the table. This one barely moved.
This was quite amusing. I hope they weren't mocking environmental friendly cars with this because that would be so wrong. It might as well have been something to raise awareness, though I don't get the point of using a Beetle for this.
Nice slideshow Rich. Love the huggable car from Phoenix Contact. I also like the energy-grabbing dancefloor. How many times have you heard people say "I wish we could bottle that energy" when they're watching active young people. With this dancefloor, now it's possible.
I haven't experienced the energy saving dance floor-yet. I also love the people powered sidewalks. Toulouse, France tested them out a few years ago to power the streest lights but I haven't seen any news or results since.
Follow up on real-world applications for these amazing new technologies would be great!
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.
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.
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.
We still have no information on how much the floor deflects, without knowing that there is no way to make a valid evaluation. A half millimeter deflection would not be noticed, but a 2 or 3 mm deflection would attract a lot of attention. Possibly we could calculate the deflection needed to deliver the power claimed, except that we have no information about how much energy the dancers deliver to the floor, nor do we know anything about the efficiency of the capture mechanism. Without any information the very best we can do is to offer blind opinions, which, if we do that, we need to qualify them as blind opinions. That keeps us from looking foolish when the facts become available.
Concerning the dance floor... this might be a great thing when getting some exercise is whole the point of the dance... or whatever other activity could be performed on the floor. Imagine the power that is expended doing aerobics every year.
So, there might be a market in the health spa/gym business for these floors, as well as for a few other person powered generators... Stationary bikes, steppers, even lift machines could all be designed to convert the spa members' output into usable electricity, though I'm not sure that it would be cost effective.
But it might make an interesting marketing scheme... 'The Power House Gym' or 'The Green Room Spa' and like that.
Good points, RalphyBoy. Gyms do have tremendous potential for human energy to be converted to electricity. Stationary bikes, cross trainers and, yes, even dance floors could be kicking energy back into the grid.
Jhankwitz its true in order to generate more energy the more energy needed to be provided by the dancers,It is a rule you dont get anything free of cost .Havent toy heard newtons law To every action there is equal but opposite reaction
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.
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.
I beleive the concept of green car is removal of pollution and its an hybrid car .I am too very excited to watch the unmanned vehicle because i have also designed an unmanned vehicle which moves towards the desired location after receiving the address interms of latitute and longitude.Sonaar can be added to it for obstacle detection
My design, you mean to say that green energy means that energy which produces less waste and causes little changes in the enviornment ?Is this energy produced by solar,wind and other alternative sources am i correct
"green energy means that energy which produces less waste and causes little changes in the enviornment ?Is this energy produced by solar,wind and other alternative sources am i correct "
Debera, you are right up to an extent. Green energy means less pollution, ecco friendly etc, while usage and during the process of energy generation too. In that sense, solar & wind are more ecco friendly.
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???
Time was when sports equipment was made only from common, everyday, low-tech materials. But now sports equipment has a new, high-tech ingredient that is helping players take their game to the next level.
