While physically possible to "recover" energy in the act of slowing down a vehicle, at the of the day, it is probably not economical.

Yeah, right, we all love bumpy roads, don't we. . . The transportation engineer who brought this idea to the table would be out of work sooooo fast.

Aside from safety and comfort considerations this idea id essentially a tax on transportation. There are safer and more direct and less complicated ways to do this through legislation.

The principle behind this is interesting. I have recently come across health gyms that have linked their treadmills and steppers to power generation equipment to run the lights in the gym. Your idea is very similar and I don't doubt that there are other applications of the same concept that make use of otherwise unused energy.

How about extend this to other traffic areas, such as the flooring in the local mall. Or maybe recapture some of the energy from the teens down at the arcade that dance on that pad. I see lots of potential here. But as mentioned before, making it economical is the key. <tg>

Good concept, but I cannot imagine any chance that we could capture enough energy to pay for the device.

A similar idea, in the real world:http://www.hughesresearch.co.uk/index.htm

And if people have a pace maker? interstim? or other electrical implanted device? Seems like you haven't thought this one through

There was a report on the tv last night about a fella in India that built just such a device. I consisted of "fins" that depressed in traffic and spun a generator. It produced enough power to flicker a light bulb on & off. It looked like a serious road hazard to me but I suppose it was only a prototype.

There is no "free" energy. In this case, you would lose energy over-all because the cars would require more power to push themselves over the vanes or bumps, etc.
