If these cells are not too costly, they could also be installed in the area of shock absorbers or springs of vehicles to provide battery charging for them.

A couple of years ago I had seen a news article which described a similar product which was meant to be installed on the surface of walkways in malls. The electricity was produced by the walking force of pedestrians. It seems that the principle is the same. I haven't seen any reports on that product since. I wonder if this present product is linked to the mall device. I think that, in theory, the highway "buttons" would work. However, I wonder about overcoming the constant wear-and-tear provided by multi-ton vehicles. Also, I'm sure that retrofitting existing highways would be prohibitively expensive. The most feasible situation would probably be to install the system when installing new highways and when resurfacing highways. Altogether, I think this has merit and I would like to see it pursued.

there is not a free energy available. basically this will cause you to lose energy thqat has to be replaced out of the gas tank. I would say it is ok on the down hill side of the road where you would be using the brakes anyway.
