Nice, being able to collect battery material with equipment powered by the same type of battery could be great for furthering public confidence.

In order to power all the electric cars we have t go back to coal. This current administration is a king it harder to pull natural gas and they want to further strain the grid. Idiocy

Until I personally feel the "strain the grid" in the backs of my knees I don't believe it is happening. Carry on.

It's all about YOU then. As long as YOU didn't lose power, there's no such thing

And yet being “charged” my a fleet of diesel generators for days is more of a laughingstock, while the diesel powered trucks will work full work schedule shifts. But hey, it’s an option. Doesn’t mean it’s a good one. It’s like bbq fund raisers for PETA

Obviously this is just for testing, in daily usage they would be charged from the power grid because electricity is way cheaper than fuel. Also EV is perfect for vehicles that make short trips in a single area.

Energy generation will obviously through market forces alone become sustainable. If you look at any trend over the last 10 years it is beyond obvious. Even dirty generating power plants are more efficient than in vehicle combustion.
echoshadow5 t1_ixszswy wrote
Market forces? Ok simple math problem Which of these market forces generates energy the same as a gas powered power plant? Which vehicle are we talking about? A hybrid? A PEZV vehicle, or how about a diesel simi truck? For how long? A year? A day? An hour? Please do tell where that info you got came from? A study or just from a tiktok clip or a tweet?

Tony Seba over at RethinkX does great work and has a proven track record. Plenty of charts in his recent talks, but go back 5 years there and it's damn accurate to today.
It's about cost per kwh, not about effectiveness of one building.

Ok, I did not expect a market analyst presentation. I wonder what his thoughts where with crypto.
BLSmith2112 t1_ixtaoi6 wrote
Not sure exactly, my focus of research over the past 5 years has been mostly on energy/automotive, haven't read anything from his opinions outside of those two.

Electric mining equipment is nothing new. Giant crawlers have existed powered by massive electric cable tethers.
This just cuts that cord. And even if they are recharged on site by diesel generators that is still more efficient in the end. Diesel/electric hybrid technology has been around for decades
Why are you so threatened by EVs?
HAHA_goats t1_ixqr9hp wrote
Gotta quibble that efficiency claim.
Gensets have pretty poor efficiency. It's not likely to be more efficient than the on-board engine. You get some benefit when scaling up, so one big generator is better than multiple small ones if you have a consistently high demand. That leaves a little room for gains if you'll be constantly recharging multiple trucks. But that will almost certainly be offset by losses in the batteries themselves.
Fossil fuel power plants on the grid just use a much more efficient heat cycle than diesel. It's hands-down better to charge vehicles from the grid or renewable.
edit for the stupid: I am not arguing against battery EVs. I'm just pointing out that charging them with diesel gensets isn't beneficial.

This is simply a stupid take. This is obviously a test piece and eventually renewables will take over and the power grid will become clean. Arguing for any other way forward is idiotic, for the life of me I will never understand why people are so enamored of old technology.
echoshadow5 t1_ixsrr6v wrote
So any kind of criticism is now offensive and counterproductive? What renewables are you taking about? Let’s just clear the air. Is the current way better? Fuck no. Can it be better? Hell yes. Old technology built this modern world. Improving old tech with new tech is the way forward. Case point: Asbestos. Everyone and their momma rave and ranted, it was all over Popular Mechanics, and countless Engineering articles. A few decades later what have we found?
crazyjames1224 t1_ixssc1a wrote
Definitely not what I said, I never implied all criticism was bad, I only said that your point was stupid, which it was. Also renewables are largely solar, with some wind, hydro, and geothermal mixed in where appropriate. Solar is everywhere now, and it’s big money because the utilities can buy the power from a solar farm cheaper than they can generate it from fossil fuels.
echoshadow5 t1_ixsyuvx wrote
Oh good solar. How good is your math? Simple math problem what is the output required to recharge an EV? How many hours in the day is it good for? Wind power: it’s a good source, if space is available. Geothermal, who has it? Hydro, that is actually very sustainable. Yet it’s geo locked to rivers and flooding a good size valley. You should be able to answer that right. It’s simple.
crazyjames1224 t1_ixtxjw1 wrote
Jesus Christ do you know what a battery is? I literally work in Solar the output is whatever you want it to be based on the field size and whatever transformer you’re using, with a battery storage system it can output all night too. I have no idea where you’re getting the idea that EV’s have this crazy charging requirement that can’t be met, it just isn’t true.
echoshadow5 t1_ixty6a5 wrote
So you don’t know math is what you are telling me. It really is a math problem. You clam to work in solar, are you a salesman? Must because you can’t answer a math problem. I’ll help you out a bit. How much kWh can 1 solar panel produce in a day. Now figure out what size kWh battery you want to charge. Do the math. You can do it. I’m rooting for you.
Oh you didn’t try to answer the other renewable energy questions. At lest name one geothermal power plant.
crazyjames1224 t1_ixtz41c wrote
You clearly don’t know Solar because you’re asking about mWh from a single panel, then you’re asking about the battery size? The battery is sized to the field. If it’s a 500 megawatt site (which is a small one competitively) then the battery will be sized accordingly so that the site charges it during the day and then discharged at night to keep power flowing into the grid.
An EV will take about 50kWh to fully charge, and that can be done with a single 50kw string inverter and about 150 individual Solar modules (panels). So with a single inverter (there are literally hundreds on some sites) I can fully charge an EV in less than 30 minutes with a super charger.
And before you give me shit saying about the dumb wall charger taking way longer, yes but it will use the same amount of power overall to charge the vehicle because it’s still the same amount of wattage.
You keep acting like there’s some magical math equation that makes you right and there isn’t because you’re not.
