I read the story.
I saw the comments on the story
I laughed at the pedantic slapfights happening in the comments.
I came here to comment on the neat story and poke fun at the silliness, to find the same pedantic slapfights here.
Sigh.

yes it does. just going by the numbers posted operating in the space it does results in a net loss of12% battery each trip.
EV never has to be recharged... Because it recharges on the way downhill.
"World's largest EV never has to be plugged in" is sufficiently click-baity without being so dumbly self contradicting
Yeah I was gonna say I'm pretty sure this isn't a single use, disposable vehicle
More like “never has to stop working to charge”. It is novel that its charging mechanism operates as a function of doing its primary job.
Not novel. I think there was a train somewhere in Africa, that transported some ore from mountain to port. On the way down with ore it charged and uphill it used charge.
Is novel for a dump truck to use this. Of course it’s not a completely new concept entirely.
That’s genius. Who cares if thermodynamics wins, it weighs less on the way up so works out just fine.
Just like the example in TFA.
Reminds me of some guy with a OneWheel that was saying he'd never charged his board in like a thousand miles as his daily commuter.
He lives near the top of a mountain lift, so he takes it home and just runs on pure regen lol.
So he's just breaking? What a silly thing to claim. I bet he's not even regening a lot. When i ride up a mountain until my battery is down to 40% or so and ride down i regenerate around 1% or something. It might even be in the 0.6% or something
I think it's still pretty cool. Turning potential energy to kenetic
It's slightly less impressive when you realise they could have built a massive slide instead and got mostly the same result.
Guess it's better than a massive diesel truck though.
"World's largest EV"
Blatantly untrue. Larger EVs have been in use for more than a century at this point in the form of EMU trains.
The emus have trains now?!
Yeah we're proper fucked tbh
Take that Australia!
It was part of the treaty. That and the Great Dingo Barrier.
We truly are lost...
Bagger 288 is also electrically driven. Even if it is connected by cable to a nearby powerplant.
I'll pick up the pedantic torch. Trains are made of train cars, I'd argue each one is a separate car or vehicle even though they're strapped together.
I feel like The ISS ticks a lot of the boxes for a vehicle though, how big is that?

The dump truck, at 45 tons, ascends the 13-percent grade and takes on 65 tons of ore. With more than double the weight going back down the hill, the beast's regenerative braking system recaptures more than enough energy to refill the charge the eDumper used going up.
I guess it all depends on the physical layout but this seems like a very complicated way to get material downhill.
So the energy this truck uses is harnessed via mining and loading... Essentially this energy was stored in the ore via geological processes.
This truck uses continental drift as his fuel.
The truck has a penis?
Or in physics terms, potential energy.
Since everything seems to be going downhill right now, how would I harness that power? You telling me the crystal peddling influencers were right all along? 🤣
I've seen a cable lift that worked basically like that. It transferred ore down the mountain, so heavy buckets going down lifted the empty buckets back up.

Kinda like the mine in the UK that use a cableway without a motor to bring ore down and empty buckets up

Reminds me of this ropeway thing that Tom Scott covered that doesn't require power input either, for similar reasons:
Niche application but still cool.
ARGH Why did you have to remind me that Tom Scott is still missing from Youtube!
Is that just a gravity battery that just so happens to be a dump truck as well?

No one commenting on the fact that the first paragraph says it doesn't even CONSUME energy????
I think it's clear they are sensationalizing it due to the unique nature of the energy used, which is external potential energy that needed to get down the hill whether it's a gas or electric truck.
Technically it would be impossible to consume energy unless converting it into mass (or time I guess but thats purely theoretical)
Amateurs.
The 1963 Černý Důl – Kunčice nad Labem aerial ropeway is over 8 km (5 mi) long, over 30 m high in places and carries 135 tons of limestone every hour from a quarry to the nearest train station. Its 120kW 3-phase synchronous motor requires power for a few minutes at the start and end of each day when most of the 800kg-capacity trolleys are empty, and spends most of the shift generating mains electricity and acting as a speed governor. Unlike the EV, it is fully autonomous most of the way, only 5 people are required to operate it. (Loading, unloading and timed dispatching is automatic, arriving/leaving carts just need to be checked; a safety latch has to be manually dis/engaged on trolleys passing the check.) The quarry will continue operation as long as it pays off, then the ropeway will be scrapped (projected 2033). A dude illegally rode the way up on it somewhat recently. He could have fallen to his death if he pulled the latch.
There's also one in the UK Tom Scott did a video on.
I know, this one is shorter and has mechanical brakes. Not as great but I imagine the Czech one, one of the largest in Europe, has very few English-language sources that could have pointed it out to him. I don't know whether the Claughton one cannot be ridden or Tom is just squeamish about safety (see description) but the Černý Důl one definitely can, that's how they do routine inspections.

Till elon finds out that if he manages to cover the sun, he can charge us on sunscription
Pretty sure its also not solar. The machine gets loaded with weight at the top of the hill, its regenerative brakes store power on the way down, it drops the load off, and the lightened machine stored enough charge to drive back up.

You just toss it when the battery dies and get a new one.
Just like a vape stick.
