Smart-City Technology Harvests Energy From Footsteps
4/22/2013

These tiles can harvest energy -- up to 8 watts per footstep -- that can be stored and used to power streetlights or other infrastructure in urban areas where there is significant footfall.   (Source: Pavegen)

The tiles -- made of recycled polymer concrete and assorted polymers in addition to tire rubber

Wow tiles build by recycled polymer and tire rubber means smart-city with go-green technolgy. This adds as a bonus to environment.

I thought that was a good use of recycled materials as well, AnandY, especially since tire rubber itself is such a wasteful product. What better way to reuse it then to turn it into something that can create energy?

How's this on the feet?

That is a great idea, but I'd like to see how it feels to walk on this material. To create electricity, I would guess it would need to have some give. If this material is anything like the recycled tire material used on playgrounds, it will be a less than desirable walking experience. Walking on the playground material is like walking in a trampoline.

Yes, it definitely has some give, from what I understand, Rob. But I don't think it's TOO sponge-y. The flex is 5mm, which isn't that much, so I imagine it would be a little bit like those people movers at airports. But I don't know for sure. I guess the only way to know is to test it or talk to someone who has.

Elizabeth,  Very interesting technology.  Any idea how early stage this company and how many installations they have already placed?  Thanks.

I'm surprised to hear that they can generate 8W for the duration of a footstep. Can you imagine how much power could be generated if you put these in a place like O'Hare Airport in Chicago?

Elizebeth very surprising technology and if it really generates 5W of kinetic energy per footstep than it can be very usefull by placing these tiles in large malls because their is usually large crowd which when walk will help to produce large amount of energy.Secondly it can also be used Near Muslims pilgimage place Kaba where thousand of people are continously moving around .

Other than this tile technology i have come across a japenese shoe technology as well which helps to generate electricity . The shoe looks like a sandal with a watery cushioned sole inside it when you  put weight on it the water sloshes to generate power ,Generator attached to each pair helps convert   the power into electric energy which helps to juice up your ipod or any electronic device .

I think there would have to be some give in order to generate the energy. A little give may not be a walking problem. Actually a little give will help walkers burn more calories, much like running in sand, but not to that extreme.

I often am skeptical about the real potential for new ideas to go platinum, (so to speak), but I agree -- O'Hare terminal, or the Manhattan sidewalk are energy sources just waiting to be harnessed.   So, while there were many engineering points not clarified, I accept that's their proprietary right as the technology is being developed.  I decided to dig a little deeper; not so much to investigate the technology, but more to see how I could invest in it.  I learned they are still privately funded, but I'm going to put them on my radar. ( I missed DSL in the 90's and 3DP in the 2000's). This could be huge.
