I see. I obviously missed that point, not having seen any reference to burning
brakes, although I use regen all the time to save my own.

But the point is, it is -far- less than the loss of a huge diesel running at
idle on the way down and burning up all the potential energy in heat in the
brakes on the way down. Bob

I'm surprised that no one has brought up, literally and figuratively, the
energy involved in making that big truck work "better" going downhill.
Doesn't the description of the activity imply that elsewhere (top of the
mountain) is a loader or loaders filling the vehicle up with potential energy?
There would be payloaders, belt systems, some form of huge dispenser of mass
creating or moving the material that has to be moved to the bottom.
As with water generated power, there has to be a source. In this case, the
source is overlooked, but that's okay.
Also, there's no reference to inherent efficiency losses. That aspect is all
too often ignored, especially from people who tell me I should build a
generator into my spare tire and run it while I drive, to recharge my battery
pack!
I'm sure everyone here recognizes that there is still a net loss and in the
case of the loading equipment, I'll venture to guess that it's a severe net
loss.
