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.

I hope OpenTTD devs consider adding gravity-based electric transportation of heavy loads as an option

No one commenting on the fact that the first paragraph says it doesn't even CONSUME energy????

[-] frayedpickles@lemmy.cafe 3 points 1 week ago

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.

Very interesting use case but kind of dependant on this very specific setup? I feel like an even more efficient and low maintenance method would be like... a ramp.

[-] finitebanjo@lemmy.world 2 points 1 week ago* (last edited 1 week ago)

Well sure but if you just dump ore onto a ramp/chute then you're constained to high angles and material so it can't also double as a drivable road.

Marl is an earthy material rich in carbonate minerals, clays, and silt. When hardened into rock, this becomes marlstone. It is formed in marine or freshwater environments, often through the activities of algae.

Does it discharge extra energy into anything else? Does it burn off extra energy as heat to maintain regenerative braking?

[-] Ferrous@lemmy.ml 5 points 1 week ago

Great question.

That is definitely one of the big caveats of BEVs over diesels. A battery on an EV can only take in so much energy. Once you hit that ceiling, the battery won't take in any more current. Fun fact, having a super charged battery in a BEV causes all sorts of headache and can cost you performance.

You either have to switch back to service brakes or, as you mentioned, burn off energy as heat. Not sure how they're doing it with this truck, but on other BEV loaders which I've worked on, we add a hydraulic valve whose only purpose is to create flow, pressure, and subsequently heat. It basically just adds a dummy load. I suspect they tapped into the dump hydraulics and added such a valve for this truck.

It powers a massage chair for the driver

Stupid title. It recharges every trip.

[-] Allero@lemmy.today 6 points 1 week ago

It is very obvious they meant it draws no power from the grid. And it doesn't, indeed, acting fully autonomously.

I'm no phycisist but I'd bet that the claim "it consumes no energy" is almost certainly false. I get what they mean but this isn't exactly a honest way to describe it.

~~energy is converted and never destroyed so it's true~~

Oh cool they're using the same principle the guys at Edison are using for their logging trucks on a much larger scale
