The topic seems to be linked to the concept of a material absorbing energy under a load and bouncing back thus transmitting the same energy to the load (bouncing ball or someone bouncing off a trampoline). It would be interesting to investigate if more energy can be extracted from the material...

As i seem to recollect, the wheels of toy vehicles , given an initial torque, revolve much longer when held in the hand as compared to the time they spend on the ground. As mentioned earlier , rolling friction seems to be a major component even in cruise mode (or there would be slippage etc )...

As far as turbulence and vorticity are concerned, i suppose there would be a boundary layer separating the laminar flow from the turbulent which would be relevant for our purposes. Regarding the main topic, it is all about harnessing the energy absorbed by the road / track. Otherwise there...

The wind powered / propelled prototype looks interesting and would be useful in areas with constant wind (assuming that there is enough wind for people to enjoy a cool breeze !). Presumably, the wind power feeds into a system of turbines / generators that move the vehicle in the forward...

One could view the problem as that of a rotary toothed profile engaging with a linear toothed profile (which may be a mix of different pitches and which may in general , not be in resonance with the rotary profile). If an initial force were enough to keep in things in motion for ever...

But we do need traction / friction, d'ont we or vehicles would be slipping / skidding. Besides, what is miniscule at the level of a single vehicle at a single spot would be sizeable when one considers the total mileage of all vehicles along an entire highway. Besides, as compared to other...

Original Post " 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? " Reply "Originally Posted by Ivan...
