Regenerative shock absorber

Why not put the magnets in a tube(say 4-5 of them) north to north south to south and then wrap a copper wire around the outside to make power from the movement of the magnets? If you have 4-5 500 pound magnets that should allow you to wrap the copper pretty thick to make more power?

Oh and when I say 500 pound magnets I mean magnets that when slapped onto a iron beam it takes 500 pounds of pulling force to remove it!

If you have two magnetic fields in opposing direction and these are moved past a conducter they will produce current in opposite directions hence no electricity will be produced, it may produce a small current because differences in field strength and each magnets proximity to the coil.
Just a singular magnet in a coil will want to maintain it's position when the circuit is closed, the only issue is it would have strongest resistance in it's centre position and would lose strength as the field moves out of the coil ends.
Using a magnet between two coils may be the best idea, it could be a continuous coil but I think winding has to be reversed so current generated always flows in same direction, or each coil could go to bridge rectifier and then to a charge controller.
The biggest problem lies in the variability of voltage produced because of the infinite range of movements (speed and distance) possible, this is one of the biggest problems with usinging renewable energy sources effectively.

The tube can't be a ferrous metal. The magnetic force won't penetrate enough to induce a current in the coils. Nonferrous metal wouldn't work well either, at least not for power generation.

Watch this.

Galane, my physics professor showed us that, but I think that he had a far thicker pipe, for whatever reason.

If you held the pipe in one hand and dropped the magnet with the other, and then dropped the pipe straight down, what would happen?

That's a great looking design. The ability to not only capture "pumping energy" but also actively pump the damper oil is great, allowing them to control pitch and dive body motion during dynamic manoevers.

This would be one of those bits that would easily integrate into a vehicle's various driving modes, where in, say, Eco mode it would reduce body motion control and favor energy capture. In Sport mode it could be set to favor body control over energy capture.

I'm not sure how much electrical power the current MR damper technologies use to constantly vary the damper fluid's viscosity, but a system like this could likely perform in a similar fasion while using far less energy, and even generating energy if desired.

Neat.
