Battery-free TPMS
The latest vehicles use a TPMS system without any little batteries in the sensors - it relies on the centrifugal action for energy. Do any of the aftermarket TPMS systems for trailers use this tech...

What I would consider ideal would be an internal sensor that had a rechargeable battery that is charged by the centrifugal action of the tire and wheel.
If there was a device that produced power using only centrifugal force, couldn't you just put a brick on top of it to get free unlimited power?
Probably be possible but not necessary. We have newer Challenger that has no battery in the sensors at all and works great.
That's the kind of thing I'm looking for.
