It’ll become rarer, but will never go away. As long as diesel is being made, heavier duty trucks will have a diesel option.

Even if it becomes a solely biodiesel option. You’re just not going to beat the efficiency, energy density, and quick refueling of an internal combustion engine until you can have a battery 1/15 the mass for the same energy, and can charge the thing in under half an hour, and doesn’t cost more than the vehicle itself when it’s time to replace it.

ICE engines, and diesels in particular can run for millions of miles. The record for a semi mileage is just over 3 million miles on the engine. You’re not going to find a battery pack that can go anywhere remotely close to that long. Especially in a heavy use vehicle like a truck that will be constantly going through charge cycles.

Just looking at the Tesla semi, the 500 mile range battery is 900kWh. A 100kWh model S battery costs $15,000 to replace, with $13,500 of that being the battery itself. Scaled up, the semi battery would be in the $90-100k range to replace.

The average semi runs around 100,000 miles per year. If you can get 1,000 full charge cycles out of the battery, you’d be replacing one every 5 years to the tune of nearly $100k each time. Not to mention replacing the electric motors themselves at several grand pop, and those don’t tend to last as long as the battery. Especially in a truck hauling 82,000lbs.

For a freight train you absolutely couldn’t. Even high power lines aren’t powerful enough to power the electric motors on a locomotive through the standard way that things like light rails operate.

That locomotive example I used has a 4.5MW electric motor output. It would be next to impossible to get 4.5MW from the line to the motor using a third rail or something. The power draw would be too great for a freight train with say 6 locomotives. I live 50 feet from a rail line and 6 locomotives is about the average I see per train.

And just for scale, there are over 26,000 Class I locomotives like that in service. If each one ran for only 12 hours per day on average, that would eat up half a trillion kWh of power per year. That would be 12% of the total US electricity production per year, assuming no losses in transmission or efficiency.

Most if not all freight locomotives are diesel electric as well.

You’re just not going to beat the energy density of diesel. 1 gallon of diesel fuel has roughly 40kwh worth of energy in it. Modern diesel motors are around 35% efficient.

So you’re looking at ~14kwh of useable energy from 1 gallon of diesel, weighing 7 pounds. So 1kwh is around 0.5lbs.

1kwh of EV battery currently weighs ~13-14lbs based on the model 3s battery capacity and weight as well as the Hummer EV.

So on a train or truck with a 5,000gal tank (just using the AC600X locomotive as an example), you’re talking 35,000lbs of carried fuel and 70,000kWh of useable energy.

To carry the same energy, you would need 910,000-980,000lbs of batteries. Twice the weight of the locomotive itself. Even if we increase the density by a factor of 10, you still need almost 3x the weight of batteries as you do diesel.

And the time to charge a 70MWh battery would be insanely prohibitive. Like a few days each time. With a 1MW charger you’re looking at minimum 70 hours if you could run at peak power with no losses. Realistically more like 80 hours with how chargers slow down as the battery gets full and charging losses.

Natural gas could used to be a little bit cleaner, but CNG vehicles use 12-15% more fuel to get the same power than diesels so it would really be a wash on CO2 emissions. And you would have to replace every diesel engine out there along with all the infrastructure just for a less efficient power source. Natural gas is phenomenal for large scale power plants, not as much for ICE vehicles.

It’s the same issue with large ships. You just can’t beat the energy density of petroleum. And ships use the nastiest byproducts of oil refining already because they’re so cheap. Banning using bunker fuel would just cause them to switch to diesel for a little more rather than go full EV. Going back to sail boats is going to happen before EV boats lol.

Same with planes. Batteries are just too heavy for aircraft in any large capacity. Plus it’s not like we really want a bunch of giant flying lithium bombs overhead. Putting out an EV fire is already insanely difficult. Imagine trying to put out the fire from a battery 10x larger that crashed in the woods somewhere.

Diesel isn’t going anywhere any time soon. I would imagine we start producing more biodiesel before the really heavy machinery goes full electric. And as long as there is diesel in use, it’s gonna make its way to consumers in large pickups because diesel can’t just sit around forever and companies are gonna do whatever they can to keep production high to make money.

Definitely not. Passenger cars will go EV relatively quickly, but you’re not going to see ICE go away in your lifetime.

Heavy duty trucks, aircraft, ships, etc all use petroleum combustion. That’s not going away any time soon. And as long as that’s still around they’ll still be making diesel.

You’ll end up seeing EV half ton and quarter ton pickups, potentially EV replacing the gas option in 2500+ trucks, but they’re going to have a diesel option for decades.

Huh I guess 4 guest appearances on a soap opera outweigh her entire musical career, including 2 Grammy nominations this year.

Just like when they banned shared accounts too I bet.

And has been doing it for years with the Ryzen G series chips. They have built in Radeon graphics chips. Not as powerful as a discrete GPU, but enough for a lot of people.

And if you spend a couple hundred bucks on insulation, you don’t need to preheat anything in your garage either.

Cars have had remote start for a long time. But you can’t just leave a gas car running in a closed garage. That’s a good way to accidentally take the forever nap.

Gonna be real fun to see the crash test rating.

Without crumple zones, all of the kinetic energy goes into the occupants.

He’s always been a shit head like this. He just got rich enough that he thought he could get away with showing his true colors.

The dude comes from a family of slave owners and was born with a silver spoon up his ass.

The difference is HBO is a media company that largely operates in the US, and Jon Oliver making fun of them isn’t going to hurt their business at all. Apple is a hardware company that also makes media. And selling hardware in China is critical to their business. Since the CCP owns China, they can get their panties in a twist and just ban Apple. Like they did with government devices.

As a publicly owned company they have a legal responsibility to maximize profit for shareholders. It’s the same reason why Twitter had to agree to the sale to Elon Musk and why they had to force it. It was a terrible move overall but since Elon was buying all outstanding shares and taking it private, the board literally had no legal choice but to take it since he was offering well over market value.

Public companies don’t get to take moral stands when there’s money on the line. They legally have to put shareholders first.

That’s got nothing to do with Microsoft though. Their reactor wouldn’t be used to power other people, only their own data centers.

They currently buy that from the grid, and they don’t really have any control over the source of that electricity generation. We should absolutely be pushing the power generators to go with renewables, but Microsoft isn’t a generator. They’re a customer like you or me.

They’re looking at moving to small reactors eventually because of the cost of buying from the grid, not for the environment.

You comment has one minor flaw.

Small modular reactors are a thing now. NuScale has already had their VOYGR SMR plants approved for use in the US. Westinghouse has one that should be ready for sale in the next few years too.

Large nuclear plants aren’t economical for profit generation right now, but SMRs definitely have the ability to be economical for huge power users like Microsoft.

And only the key operated ones. Push to start are not affected.
