Using electro gravity tiles, there is an emerging technology that can generate electricity from moving vehicles. If we continue to populate the highways and roads, we might as well extract energy from their motion. How cool is that? "

This is completely bogus. The energy from the tiles comes from petroleum powering the cars. It would be an extremely inefficient means of converting petro energy to electrical energy"
My Thoughts :
A car expends energy in moving forward (and overcoming friction). Unless the car continues repleneshing its energy sources (through the accelerator), it is going to come to a halt eventually, even without braking (Otherwise, one would keep moving in a state of uniform motion or skid)
So at every moment, the car is imparting some stress to the surface of the road. I feel it should , in principle be possible to avoid dissipation of energy as heat if one could have transducers below the road surface converting the pressure / strain energy to electricity and storing the same (even on straight stretches)
When considering density / tonnage of traffic on busy highways, this should translate to a sizeable amount of energy over a period of time. I guess efficiency etc is a matter of engineering and / or demand / economics / mass production.
Possible applications :
- Lighting up highways at night
- Controlling speed of cars (by tuning the amount of energy absorbed at different sections of the road) and reducing need for braking and / or making braking easier
- Auxilary source of power for track electrification in case of rail traffic.
