So, an engineer or physicist you're not? Otherwise, compare for us the energy density of the best battery that you can find with the energy density of a hydraulic accumulator.It is far more intelligent to use hydraulics instead of a big ass battery.

That's pretty much the idea. In an accident there are two places all that energy (and even with small vehicles that's a lot of energy) can go: absorbed by the car or absorbed by the passengers. The car is designed to crumple up and absorb the impact. Personally, I'd rather replace a quarterpanel than a hip, yknow?The Prius will fold up like a paper cup in a crash.
That seems somewhat inefficient. Why would you want to generate power to supply something to generate power to move the vehicle? Unless I'm not getting the concept here that's just adding an extra step.I think the idea is to use pumps powered by gasoline or electric motors to generate hydraulic power.:uhoh:
There is a trash truck out there that uses hydraulic accumulators to assist in powering it. Probably makes alot of sense on a vehicle that stops and starts as often as that does.Doug Huffman wrote:Michigander wrote:So, an engineer or physicist you're not?

The US military is using hydraulics on tanks, and the UPS is using it on delivery trucks. This technology has been around, but has been largely suppressed, for several decades. It is a damned disgrace that it has actually taken the US government to bring it forward. It tells you a lot about auto makers.Gordie wrote: There is a trash truck out there that uses hydraulic accumulators to assist in powering it.

No. I'm retired. I've done all the neat stuff already and made most of the mistakes that I'm gonna make. Your turn, you can start with hydraulics versus a big ass battery.Doug Huffman wrote:You're over thinking it.Michigander wrote:So, an engineer or physicist you're not?
