I'm hearing $6 diesel in some places. That's very bad.

incredibly, the industry can absorb it for awhile. but long term high diesel costs will put half of trucking out of business, happened in 2008 also.
@Evil_Bender
Of course that would happen the year I start CDL training.

If you get a job with a big trucking company, sooner or later they're gonna put you in a Tesla...
doubt it, there's no infrastructure for it, and the speed the governmwnt works it will be 25 years
It doesn't matter if there's only one charging station every 50 miles, they'll give you a route that has you stopping where they are.
Charge time doesn't matter because you already have mandatory breaks, and if you pull a lot of grades, you'll actually make better time because that thing has a thousand horse power unit.
10 years ago, EVs were experimental slop subsidized by greenies, now it's production stuff being bought by bean-counters.

@cjd @Evil_Bender @pepsi_man I have never seen an electric truck, and I rarely see electric cars, sounds like cap to me
The thing is they're expensive, say like $250k.
But if you're getting 8 MPG with your diesel and an electric gets 2 kWh/mile, if you're paying 20 cents per kWh then that's $3.20 per 8 miles, so you're saving like $3 per 8 miles.
If you're averaging 500 miles per day, you're saving $187/day.
Your driver's $300/day and you're gonna amortize that truck over 5 years, so that's costing you about $166 per working day (lets figure the truck is moving 300 days out of a year).
Now you take that and you look at maintenance and repair on these DEF/DPF shits and at the end of the day it just makes sense.
The sad story is gonna be for all the owner-operators who are driving their 1990s detroit diesel with no emissions, and they're gonna get fucked over on fuel and the big companies are gonna eat their lunch on freight rates.

@cjd @Evil_Bender @pepsi_man maybe in theory, but the whole charging infrastructure hasnt been proven with massive fleets of electric trucks, the whole thing is just theoretical at this point
> charging infrastructure hasnt been proven
It's not like you have to prove that the chargers will work, like as if they might mysteriously not start up and we need physicists to figure out why...
It's just a question of whether there are enough of them on the routes you want and if the price of power at the chargers is economical.
Now there's a lot of short haul shit, and for that they're just gonna charge it at the warehouse. Long distance you have to actually find the chargers and confirm the price of power and so on, but this is classic work for an office worker at a large trucking company.
If you're small, you go on trucking dot com and you find a contract and bid. If you're big, you know your main routes, you know basically how many trucks are gonna go over interstate 5 (for example) in a year, so you're gonna put electrics where there ARE chargers and where you're doing a lot of driving.
Like I said, this was theoretical 10 years ago, at this point it's pretty much inevitable...

@cjd @Evil_Bender @pepsi_man I'll believe it when I see it. They said this about cars too and it didnt happen
With cars, the math is different.
I have a diesel car and I have no reason to buy anything else. That's because the amount I drive is very little so fuel cost is marginal compared to amortization of the vehicle.
A lot of people did buy electrics, they're like 90% in Norway, but that's more a lifestyle purchase, like buying a Harley Davidson. Norwegians are rich enough they can throw down for a Tesla.
But in China, EVs are 20% of trucking, and 50% of cars so it's not like something needs to be proven at this point...

ive been a diesel tech almost a quarter of a century. I dont see any practicality to a battery operated vehicle moving 40t at 70mph for 770mi in 1 DOT allowed per day trip.
A ford lightning f150 can barely haul its 7500lbs capacity 80mi before its dead. Its a pointless technology.

and where was it this winter that got a bit cold and the electric cars all died, or California not letting you charge because of increased energy demand?
@Evil_Bender @cjd @medievalwars The fundamental flaw with EV tech, as I see it, is EVs solve no problems while introducing a whole host of new ones.
Here's the rub: The elites really REALLY want EV tech bc muh climate change. We're going to have to deal with it for now.
Long term, I bet we see EV box trucks making deliveries in cities. Think of something like an electric F-350. But eventually everyone will see the hype for what it is and that's hype.
> EVs solve no problems while introducing a whole host of new ones
If you're Europe or China, they solve a big problem: You need dollars to buy gas and if you try to work around that, the US get bitchy
> Long term, I bet we see EV box trucks making deliveries in cities.
My wife bought a phone and the guy who delivered it was in an electric van, and we're not city at all.
> But eventually everyone will see the hype for what it is and that's hype.
It was hype up until 2019 - which was the last year "muh climate" was a thing. Ever since then it's been 😷 💉 and then 🇺🇦 , 🇵🇸 , etc. Even Greta had to get a new job.
But then 2020 was the first year that EVs actually started getting traction, see chart. Everybody who trades in when their warrantee expires doesn't care about reliability or repairability, if the price difference between gas and power is bigger than the price difference of the car, they just buy the EV.

let me know when electric can pull a 12k lbs trailer up the mountains and not stop for 300mi and only long enough to fuel, piss and grab jerky.
I want a diesel-electric hybrid for that and I'm hoping someone like Edison will eventually have an e-axle setup that can go into GMT400/800 frames.
Hybrids have really weird economics. All of the big OEMs went all-in on hybrids a decade ago and they all got buttfucked by Tesla because they were building two drivetrains and Elon was only building one.
And as battery costs came down, everything they had done got blown to shit.
There are SOME places where hybrids could make sense, but I don't know if anybody has a stomach to go into them right now - outside of niche bespoke players like Edison.
The problem is, it takes you 5-10 years to do the engineering and release the product, build a market, fix the issues that arise, and so on - and while you were doing that, battery prices fall by 50% and suddenly your idea doesn't even make sense on paper...

Correct, I'm basically describing a corner case that is much closer in application to a vocational truck role (heavy towed loads, medium distances, limited/nonexistent charging availability)
This is a very different use space than guy that commutes to work 30-40 miles over mostly flat pavement, an ideal place to have a simple EV.

Yeah, super tricky b/c right now the Tesla semi long range version is 500 miles. Battery nerd shit that's in the lab now may be able to double that, so anyone who is trying to do a hybrid is racing the battery industry, and that a race that a lot of people tried and lost.

The problem is charging time though. Gas "charges" quickly. You can refill in minutes, and a single gas station can serve hundreds of customers a day. EV takes hours. So you have to litter the world with charging stations and wait a long time to drive.
Current best battery chemistry (currently) can charge 0-100 in 6 minutes.
You have to send The Wrath Of God through that charge cable, but the Chinese have figured it out.
They use big buffer batteries to charge from the grid and then dump them into your car when you connect.
There's new chemistry can do 3 minutes, but at that point it's so much power that you need a different charge plug.

Yeah. Tech may catch up, but it's not there yet. They also have to take price into consideration, and without excessive subsidies, which we pay for anyway.
By way of analogy.... even here with our high electrical prices, the math on solar still doesn't work out.

Solar does work, China and India are deploying it like it's the end of the world. Nothing works in California because everything is illegal except crime.
It's the price that's the issue. It's not worth putting in the capital. The return isn't there.
I won't get into the nightmare markets / agreements this had created, like fly-by-night contractors with unenforceable warranties, roof easements, problems selling real property because the solar lessor won't sign off or can't be found, leaky roofs, etc. I've seen it all.

Yea, somebody I know was a sales guy for this, in Cali.
But I mean the price people are paying for this stuff is not The Price.
India isn't paying more than 10 cents a watt for their panels, and you look at putting in a 10kw system in the US, that's not $1000.

I wish we could use those micro-systems, the ones you can throw up in the yard on a sunny day and plug into an outlet. I could see those coming in handy in some cases, and they are cheaper, but they're illegal here.
Here it's common to use a non-grid-tie inverter w/ a battery and use the grid to top up the battery in case there isn't enough sun, but otherwise just run off the battery.
Here's like 6k€ for 11kw of capacity, plus another 11kw of spare solar panels because they sell them by the pallet.
Is it just impossible to get those kind of prices in the US ?

$3.5k+/kw with battery etc. This doesn't include risk, e.g. warranty, failure before end of useful life, leaky roof, etc.
3.5k per kw is INSANE.
I don't care warrantee and insurance and shit, that can cost like 50% of the hardware, that's legitimate. 10x the cost of the system is theivery.
Anyway, there's the explanation of why it makes sense in India and not in California...

I grew up in operations. Every dollar is projected and risk taken into account with tolerances. A lot of people make the mistake of looking at pure monetary outlay alone.
Given my experience with solar companies and related issues, risk is a major factor here.
If the math worked out, that could be dealt with, since the local contractors I trust would then do the work.

I think you solve a lot of risk just by not putting the panels on a roof. If you're thinking about it like a utility, it's land and hardware.
1970s / 80s set backs are typically 10 to 15 feet on a .25 acre in the burbs, but they're starting to build near zero now. There's really no where but roof on most houses. Maybe I should make an all solar panel fence? 😏
It might just make no sense.
But still you can easily do the math in your head of how if you're a utility, you go buy a great big field of trash land that doesn't grow anything, it's dirt cheap, you hire some cheap labor to throw a bunch of panels on it, and you're making real money...

There is a related issue here to... and it's that having utilities guarantees that power is supplied to entire areas. Making the owner purely responsible for electricity, especially with no standardized installation (unlike internal electrical which is simple, cheap, and old as time), can lead to blight house by house.
they wanted $70k to put a 98% system on my home and it couldn't operate as a standalone when power went out. I was also required to be plugged into the grid and supply to others.
it wasnt worth it here for solar either
it wasnt worth it here for solar either
Yup. The "free" or "low cost" installers are a scam. Sometimes people actually pay via a solar loan and get the same shitty arrangements anyway.
As I see it, if a regular lender won't cash out refi or construction loan, so you can put on solar, it's not adding value.

a generac that runs off propane is $10k or less
You could in theory get 4-5 houses to pitch in on a 50kw generac backup and be fine. When I was a kid during the floods of 93 I remember a rich neighbor bringing in a huge generator from an out of state location that ran our whole neighborhood
What’s crazy to me is how little consideration has gone into using a car engine to power house current. It is absolutely powerful enough to run a house, probably several; but basically nobody ran that way with it.
This sort of thing has been done before, use a diesel engine as the home furnace and it makes heat and electricity. Lookup "CHP" (combined heat and power).
I think the biggest reason why it's marginal is because the hardware is quite expensive, and the cost of diesel makes the power more expensive than most grid power.
Diesel is the best you're gonna do in terms of efficiency, gasoline / propane / etc is always worse because those engines are less efficient. Diesel has 10kwh/liter chemical energy, and they're 40% efficient, so 4kwh usable, 3.745 L/gallon, so 15kwh/gallon. If you're paying 5$/gallon, you're paying 33 cents per kwh, which unless you're in California, that's higher than the grid price.
Also internal combustion engines do break down. Reliability is much lower than a classical furnace, and when they break down, people have no sympathy for why it broke down, they're just pissed and ready to throw it out.
There is some interesting stuff happening in the space, but it's pushing in a couple of directions:
1. Wood fired -> much cheaper than diesel
2. Sterling engine or turbine -> much higher reliability than an engine
Picture 2 is a wood pellet sterling furnace, 10kw of heat and 1kw of electrical power.

I don’t know the future, but one thing I do see a decade from now is a lot higher proportion of woodgas powered vehicles in rural areas

Woodgas is such a pain in the balls, the tar is super dirty and clogs things up. You can afford the scrubbers if it's a stationary installation, but if it's on a vehicle it's even worse. Then the wood needs to be perfectly shaped and dry enough.
If you're off-grid, you already need a solution to make power - so going with an EV means you just scale that same solution up a little bit more. Thomas Massie is off-grid and he drives a Tesla.
That sterling CHP is a good direction, but you want to be able to run on any wood, not just pressed pellets. It also needs to be more efficient because 1kw power 10kw heat is pretty bad. China has a thermoacoustic sterling that hits 30% so the tech is there.
And summertime = just use solar. The economics of generating power w/o moving parts or fuel is unbeatable.

Right right, hey that reminds me - do you know about Jeremiah Ferwerda’s Thermodynamic Transformer ? He had a big run-up starting in abt 2022-2023 or so, and posted pretty frequent updates at first — but has just sort of “fizzled out” last I checked.
There's a lot of that stuff out there, search the name Dennis Lee if you want a good laugh.
A lot of all that stuff comes down to "Oh wow, that's amazing, you must my mining so much bitcoin... Oh, you're not? Okay, have a nice day sir."
A lot of all that stuff comes down to "Oh wow, that's amazing, you must my mining so much bitcoin... Oh, you're not? Okay, have a nice day sir."
It's funny because actually on the topic of Free Energy, I have an idea that best known physics says ought to work. I feel like it probably won't, but even just TRYING to make it work will lead to learning something new...
I really like the concept behind the Thermodynamic Transformer - and I’m fairly certain it’d be a thoroughly excellent rig for a stationary tesla turbine power plant; I just don’t see any reason it’d go over-unity. Nevertheless the plain physics of increasing the temperature differential between either end of the turbine’s fluid path should increase its overall efficiency. That being said, I guess dupes won’t throw money at you unless you make huge promises 🤷🏻♂️
Is this the thing where you harvest energy from small temperature differences between, e.g. a river and the air?
AFAIK the problem with those is the temperature differences are so small that you need massive heat sinks to move thermal energy and still the power output is pretty bad.
I was thinking it might make sense in frigid cold where you have water access since the water is 0C and the air might be -30C, but according to GPT it's still not a very good temp difference.

I think I know what you’re referring to as a “thermoelectric generator” - which uses the Seebeck Effect and is a pretty neat way to magnify the brightness of a candle tenfold 
But in my case I’m just talking about Ferwerda’s experiment - which looks pretty cool honestly even if I doubt the over-unity claims. But essentially he’s spinning a tesla turbine by reducing the temperature at the outlet to cryogenic temps, while using hot water on the inlet side - so, not even boiling. At least that’s how I understand it. It’s pretty fascinating imo - but I’m not buying the PR 😆
Interesting, never heard of that.
> reducing the temperature at the outlet to cryogenic temps
Unless you have cryogenic temps for free - like e.g. if you're in the arctic - you need energy to make the cold side to begin with.
And if you are in the arctic, then you need quite a lot more energy to get the water hot... So it doesn't sound like it would be that useful...

Right, it’s not free of course; I think his claim is something like if you get it started, it can then generate enough electricity to keep the temperature down, with some left over. And it would be quite a find, and explains the over-unity talk; I just don’t think it would have fizzled out a couple years ago if it was really something
In order for something to give you free energy, you'd need some kind of physics anomaly to exploit, and I don't see anything about that setup which is anomalous.
My little free energy idea is based on Biefeld-Brown thrusters. They've been replicated quite a lot, so we know how to build them, but they're not well understood from a physics perspective. As best we know, they seem to have a fixed thrust per input-power ratio.
Well, output power is thrust times speed, so if you get them going really fast, like in a circle, then you should be able to get excess power.
Video: Other people who experiment with these things have had that thought too, they're kind of sheepish saying it because physics considers this quite a heresy...

I recall one guy who put in a battery array and charges from the grid during non-peak hours. That does math out here, but I'm not sure about the legality.
Now we just need generation capacity, and boomers are terrified of nuclear.
I think the military doesn't want nuclear. They're afraid that if we get into a war here at home, enemies will use them as dirty bombs.

Ahh okay, you guys are talking about work pickups.
Same basic logic, just scaled down.
See below, cute chart from 2021 predicting evolution of battery price. Battery you can buy right now that's 50€/kwh.

Can you fit 400-500KWh of battery into the frame of a 3/4 - 1T truck, and still have any payload capacity?
Current commercial (cheap) cells are like 180 kw/kg so if you're trying to hit 500kwh (which is WAY more than any EV has currently), that's gonna be 6111lb. An F350 will handle 8000 so ... you have just about a ton left.
I'd probably go for 200Kwh and it'd be 2444lb which would give about 2.7 tons of capacity.
F150 lightning only has 130kwh so even 200 is being reasonably generous.

My question was a volume one rather than a weight one though 6111lb added to a pickup probably exceeds the axle weights. A full size longbed scales around 6000lbs empty with a gross weight rating of 11-12k depending on the year and axles.
My number is based on 38KWh/gallon * 38 gallons @ 35% mechanical conversion = ~500

Nothing is as energy dense as diesel fuel, and gasoline is pretty close.
We MIGHT have batteries that are denser, in like 20-30 years, never say never, but for now energy density is The Tradeoff...
The battery I looked at is an EVE MB31 which is 0.00258 cubic meters of volume and holds 1kWh, so like 1/2 cubic meter for 200kWh. IMO it'll fit between under the hood and all of the space in the frame once the driveshaft and exhaust is gone. The real issue is weight.

most 3/4t have a payload capacity between 3,400-4,400lbs. Even a longhorn adding 6,110lbs to the frame leaves little for towing safely
There's a 360wh/kg battery being used in Chinese flying car thingies, and there's a 700wh/kg battery in the lab.
So 360 you cut the weight number in half, and 500 it's now about 1/4...
This chart is also why nobody bothers investing in anything other than batteries anymore, because by the time you get it to market, batteries eat your lunch...

Correction: "and 500 it's now about 1/4" -> "and 700 it's now about 1/4"
BTW diesel fuel in a 40% efficient diesel engine (typical) is 4KW per liter, and it's 0.84kg/liter, so density is 4760 wh/kg. This is the true mark to beat, but it's almost never really important outside of aviation.

I'm legitimately surprised that ''electric with a generator" isn't a more common option outside of trains. Diesel-electric is really common with them.
"Range-extended EV", couple of problems with those.
You actually need a pretty big engine because you expect to be able to pull hills with a dead battery...
So now you have a hybrid, and that always costs more than an electric because it's got more moving parts.
And the other guy is just waiting for batteries to get more dense, which they do, and then the applications which required your vehicle can now be serviced by the pure EV, and you lose.
That said, an electric that can be charged while driving would make sense, since you can put a genset in the bed, or trailer it, and it's a whole separate thing from the truck...
