There's a big "it depends" on these kinds of things:I also saw an article a while back that mentioned the development of regenerative shock absorbers. The concept alone is pretty awesome. As long as it doesn't negatively impact the range, every little bit would help, no?

As long as it doesn't negatively impact the range, every little bit would help, no?
Yes. Every little bit helps. The answer is always that every little bit helps. There's still plenty of wasted energy in an EV, and any research into recovery of that energy is a step in the right direction. Certainly there are some practical matters/hurdles to address, but as long as those issues approached as a problem to solve, progress will be made.
Maybe the recovery of energy from the tires causes slightly higher rolling resistance?
Could be, but if its a net gain on energy (see swengl's comment on not negatively impacting the range), its still a Good Thing. Will this tire ever come to be? Who knows, but hopefully they don't get discouraged by people that are just poking holes.
I'm trying to figure out how you can get a net gain of energy while still retaining ride comfort.
1. All the energy used in a Tesla comes from the battery. (Remember, regen just puts back some kinetic energy already spent by the battery.)
2. Due to flexing a certain amount of heat is generated (which causes the tires to increase in pressure).
If you're taking energy out of the tire, then either the heat generation is reduced or the battery has to supply the additional energy.
I don't think Goodyear's solution will have anything to do with tire pressure.
I just have difficulty seeing how that will work.
Now the question of course is does capturing this heat negativity impact the driving dynamics of the tire? And due to the unsprung weight increase from the thermo-electric generator in the tire do we really end up with a net gain at the end of the day? And is it worth is cost-benefit wise (the obvious parallel is PV panels on the roof of the car).
Absolutely. Those are problems to solve, and it may turn out that current/near term technology won't allow the practicality trade to close.
It's not a huge deal if they can't make it work now, because it will be feasible at some point. When it comes to energy, you can start with more, use less, or recover more. These tires attach the first and last.
I Look as this concept like the 'cover your car in PVs' idea. At some point that will make total sense...it just doesn't today (mostly because of mass/cost).
Could be, but if its a net gain on energy (see swengl's comment on not negatively impacting the range), its still a Good Thing. Will this tire ever come to be? Who knows, but hopefully they don't get discouraged by people that are just poking holes.
If everyone spent their time drilling into the top items on the 'wasted energy' pareto, we'd miss out on a whole lot of what Progress has to offer.
It likely would not even add that much. A mile driving uses roughly 300wh. If these produce 50Watts (doubtful), you'd have to drive for 6 hours to gain 1 mile of range. After 6 hours, I'm pretty sure you'd already have to be stopped to charge, so the extra mile won't really make much difference.Could be. Even so, if the electric tire of the future behaves and costs exactly like the non e-tire of the future, there's zero downside. Why wouldn't everyone want another couple miles range for free?
