EV never has to be recharged… Because it recharges on the way downhill.
I think it’s still pretty cool. Turning potential energy to kenetic
Yeah I was gonna say I’m pretty sure this isn’t a single use, disposable vehicle
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
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.
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 trueStrictly speaking, the energy it consumes is the gravitational potential energy of the ore they’re mining, which would be consumed anyway in the form of, well, gravity, acting on the ore on the way down. They’re just using it productively instead of dissipating it as heat from the brakes.
I think it means that the net energy consumption is zero. It can use energy, but it generates enough to offset it.
They must be hauling the load downhill, what about the ones that hauls the load up from an open-pit mine?
Very cool! It’s a pretty specialized use case, but still awesome to see.
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.
This is very fucking cool.
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.
yes it does. just going by the numbers posted operating in the space it does results in a net loss of12% battery each trip.
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.
Back in my day we drove back and forth to work uphill, both ways, and we only lost weight because we could never afford enough Starbucks and avocado toast!
Oh cool they’re using the same principle the guys at Edison are using for their logging trucks on a much larger scale
2017
At 50 tons and 700 kilowatt-hours, this truck is the biggest EV in the world Each round trip will generate 10kWh of spare electricity for the grid.
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 including loading and unloading. 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.
Damn, that shit is even hotter
Content aside, what a great video! It’s not that old of a video but it reminds me so much of early YouTube, just friends messing around and posting it with top tier song choice.
I wouldn’t be surprised if there are electrified railway lines doing the same. Regenerate large amounts of energy into the grid while descending loaded; consume a relatively small amount of energy to haul the empty train back uphill.
I don’t know about going downhill in general, but there are some that use regenerative braking (regular braking, on flat terrain) so maybe
An early version of the Petřín ropeway in Prague used to contain tanks in both cars. The upper one would be filled with
sewagecollected rainwater from the city’s hilltop quarter and the energy of the descent was used to pull the other car up. Additionally, the way up cost twice as much so there was an incentive to ascend on foot, which was about as fast despite the incline.Neat.
Paywall article, but this already exists in Australia for pretty much the same use case: https://www.railtech.com/rolling-stock/2022/03/04/australian-mining-company-works-on-infinity-train-using-gravity-to-regenerating-batteries/?gdpr=deny
Most mines are underground so for most this can’t work, but where it does they are sure to use it.
Regular trains don’t run underground. Lots of opencast mines exist .
Basically all mines have an above ground terminal where whatever you mined is unloaded from your underground trains, lifts, haul trucks or whatever else onto storage piles, then loaded onto the actual long distance trains.
If the mine entry is up a mountain, then the trip down from that point will be a net energy producer regardless of anything else.
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.
Cool EV bruh, but can the horn make a fart noise?
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)
