Only if they take their three very fat aunts downhill
But if they walk up the hill they will become less fat and provide less energy?
How are they doing over there with perpetual motion?
It’s the same thing, only different!
This one works.
Guess the author can’t afford to be too picky.
It’s a job and he is employed.

And the carbon footprint to load it up each time it leaves a port. And the carbon footprint of the “at sea resupply” support vessels and logistics. Resupply of naval vessels at sea is a huge infrastructure, very much larger than the Navy it’s self.
You mean I no longer have to turn my car radio off to conserve electricity?
Only when you are running regen and the battery is topped off.
My wife’s Prius displays this info.
Crank up the volume!
Turn on the heat and AC at the same time! (defrost will do that for you).
GO APE!!! Drive it like you stole it!
But only on max regen.
Why all the cynicism here?
A guy has to have some fun!
And always a couple of Luddites, like a moth to the flame.
Don’t most quarries work the other way?
YES!
But...
Newer earthmoving equipment uses electric drive motors for better control and longer service life
Not 100% regen, but deep pits like the Udachny diamond mine would have some return.

I don’t think so.
Pls show your ciphering, so we can spot the errors?
“With the eDumper’s 600 KWh battery and its regenerative braking, the truck saves 50,000 tons of diesel each year and also reduces the CO2 footprint by 1.3 million kg every year.”
But this still only seems to mean that under 40 people’s CO2 worth is saved by all of that (Trinidad and Tobago people).
According to the CNN link at that site, it actually started at 90% and only made it back to 88%.
I have no idea where they get the “surplus energy” justification, but it’s in both sources.
Nice photos, tire chains, mud, snow...
Yes, you would want the control of an electric drive in slippery conditions!
Folks, the Green Car site doesn’t seem to properly represent the CNN report numbers:
With the eDumper’s 600 KWh battery — the same as about seven Tesla Model S 75Ds — and the regenerative braking, the truck saves 50,000 tons of diesel each year
50,000 tons of fuel???
That is like FOURTEEN MILLION GALLONS!!!
And you believe that?
You believe CNN???? Stopped clock, blind squirrels, Dumbgrunts...
Would an oil-burning aircraft carrier use that much in a year???
If it helps, I don’t believe either site.
Well come on mate - yous gotta feed dem Aunties !!!
Oopsie, I assumed your gender !
Sorry bout dat.
Don’t hiss or catcall me, I am highly sensitive and those loud noises would trigger me. Jazz hands only please !
In order for the truck to return to its starting point while overcharging it’s battery, it needs its mass increased by having an excavator or loading shovel add mass to the bed.
This is where the energy to charge the truck’s battery comes from. The extra mass allows the motor to generate enough energy to charge the battery. The amount of energy for charging depends on the amount of mass added to the truck and the slope of the downhill. This puts limits on the situations where the truck can effectively operate.
This whole scheme only works if the truck travels uphill, is loaded, then travels downhill. If the truck has to travel uphill to unload, the truck may not be able to charge enough to keep functioning.
