Kia pulled its EV6 GT, which basically did not sell well in the US. They only manufactured that particular top tier trim level in Korea, but the other EV6 trim levels continue to be manufactured and sold in the U.S. (Wind, GT-Line). Kinda stupid that they named their top of the line the GT and the one just below that the GT-Line, but brands can be stupid with naming schemes sometime.
now both Hyundai and Kia have stopped selling EV models last year solely in the US
They’re basically one company and they stopped importing EVs. They still build and sell plenty of new EVs in the U.S., made in their plants in the state of Georgia. They’re also currently expanding capacity at their plants, in the hopes of catching more of the growing electric SUV market.
So they no longer sell the top of the line trim level of the Kia EV6, or the Hyundai Ioniq 6, but they’re still building and selling very similar models on the same platform. The Kia EV6 still exists in the lower trim levels, and the Ioniq 6N and the Ioniq 5 and 5N, and their smaller EVs (Kia Niro, Hyundai Kona) are still available, too. Both brands launched their 3-row electric SUVs in the US, too (Hyundai Ioniq 9, Kia EV9).
A lot of companies are slowing down their EV rollouts, but I wouldn’t say that Hyundai/Kia is the best example of that.
Average new car price has gone up a lot because the average new car has been purchased by rich people who demand high performance and luxury features. And rich people have been doing great the last 50 years, so the top of the market has totally run away with high prices.
If you actually dig into specific models and what they go for, you see that the most basic cars have only gone up slightly in price, but are also much higher performing (0-60 times, quarter mile times, braking distance), more efficient (better highway/city gas mileage), more reliable (more miles/years to failure), and have a lot more standard features that used to be expensive add-ons (automatic transmissions, power windows/locks, power steering), and are generally better constructed (smaller panel gaps, better sound proofing/vibrations), and much, much safer by pretty much every measure.
Today’s cars, even the cheapest ones, are much better than the cars from the 90’s, much less the cars from the 70’s (5-digit odometers because getting past 100,000 miles wasn’t necessarily expected, bodies that rusted within a decade of normal use).
So if a first generation Honda Civic in 1974 cost $3000 in 1974 dollars (inflation adjusted to $21,000 today), we should compare what that car was, compared to what a Honda Civic is today (starting at around $25,000 for the barebones model, $30,000 for a few nicer features). Compare torque/horsepower specs, actual performance at 0-60/quarter mile, gas mileage, all of that. I’m not entirely convinced that the people of 1974 were getting a better bargain on their cars than today’s new economy car buyer.
I hate that cars have gotten so big, and that the SUV is basically the American default at this point. But I don’t think that car prices have actually gone up that high in the 30 years I’ve been driving. And cars from before I was driving just…sucked.
If you were already going to use the heat later in the day when fossil fuels are burning again, then whatever you can do to reduce that future consumption, through storing some thermal heat produced now, can still reduce that fossil fuel consumption overall. Water heaters, warming any living spaces that might need to be heated at night, etc.
It doesn’t even have to be efficient when prices are literally negative. All it has to do is be somewhat effective at reducing later consumption.
We should always look to nature, yes. A lot of aerodynamic designs seem to look a lot like the world’s fastest birds. Trees really do seem to optimize for capturing solar energy in an easily encoded blueprint.
But also there are a few areas where we should recognize the limits of scope of the solutions nature has provided, or recognize the path dependency in how evolution might optimize for a particular pathway that no longer should continue to pose a restriction (the giraffe’s recurrent laryngeal nerve, for example).
We’re allowed to mix and match. Just gotta be careful and recognize just how powerful billions of years of evolution is, as an optimization method.
They are clearly mathematical.
Sure. But they’re also philosophical. The categories aren’t mutually exclusive. Basic set theory (which is both mathematics and philosophy).
I see philosophy as a place to make nonrigorous arguments.
Wait do you think Bertrand Russell and Alan Turing and Kurt Gödel weren’t making philosophical arguments?
Exactly.
HERE’S A THEOREM: IF IT’S PROVEN, IT’S TRUE EVERYWHERE, FOREVER
But at the same time, even if it’s true everywhere forever, it might still not be provable, because Gödel.
Solar needs active maintenance, including personnel of varying skills. All projects have ongoing costs, especially if they’re gonna sit outside in the weather.
Better to just compare all costs, across the projected lifespan, and compare replacement costs if one source lasts longer than the other.
Doing all that tends to show that building new nuclear isn’t cost competitive. Not big reactors, not small reactors.
nuclear does better for utilities level power than solar.
Define “better.” Personally, I think nuclear is too expensive to be a current solution. Let all the existing nuclear plants continue out their useful lives, and extend them as feasible, but constructing new nuclear plants is probably not worth the cost, even compared to solar + enough grid scale storage to cover multiple nights of demand even when days are cloudy.
Terrapower just got approval to build their $4 billion, 345-MW reactor. That’s $11.6 million per MW.
NuScale canceled their 462 MW project in Utah when it became clear that the total cost was going to exceed $9 billion. That’s $19.5 million per MW.
Solar plants are about $1 million per MW. Grid scale 4-hour batteries are about $750,000 per MW.
And the costs of solar/batteries keep dropping, while nuclear tends to increase in cost over time.
It’s for showing off the engineering. Lots of robotics competitions focus on different things (throwing balls, kicking soccer balls, moving fast), but BattleBots is definitely the one I’d be most worried about advancing a dangerous line of killer tech.
A humanoid bipedal foot race shows off balance, speed, power efficiency, and things like that.
Exactly.
The whole reason why lithium is such a good material for cathodes in car batteries is because of its very low mass per cation. So for a Lithium Iron Phosphate battery, the the cathode material is LiFePO4, where the Lithium itself is only 4.4% of the overall mass of the cathode.
So it’s important to remember that although the lithium constitutes a small amount of the total mass of a battery, that swings both ways so that not much is actually needed to build the next battery out of recycled materials.
Your solar power storage expert is named Sun? Sounds lot like sun.
Maybe that’s why she became a solar power storage expert!
Also, I’d push back against the subtext that work experience gives skills. Plenty of people work a job for 10 years without having the adjacent job skills to be able to progress in that career or jump to another.
Critical thinking skills are the most important thing, and it’s possible to get a 4-year degree without actually picking them up or strengthening your skill sets in that area. But it’s also possible to work for 5 years without developing critical thinking skills, either.
In the end, no matter what you do with your time, only a small percentage of your effort is going into improving yourself. The people at work are trying to get stuff done for their employer, and the people at school are trying to get through the curriculum. It’s possible to do the work while the employer/school or even yourself cheats you out of the real long term benefits of actually learning during that time frame.
they could have bought a <$25k used EV last year and saved $4k with the EV tax rebate.
The people who were in the market for a car last year are by and large not the same people who are in the market today.
Plus let’s not forget, the actual EVs on the used market 12 months ago were different than today’s. Someone looking to buy a 3-year-old car today has to look for something originally sold in 2023, whereas 12 months ago they were looking at 2022 vehicles, with fewer models available and significantly fewer vehicles actually manufactured and sold.
For everything the Trump administration has done to make solar and wind power less economically feasible, it turns out his war in Iran has done way more to make fossil fuel consumption less economically feasible as well.
There really was a huge increase in the number of EV models available between model years 2018 and 2023.
So now, when you’re looking to buy a 3-year-old car, you have so many more EV options to choose from even compared to just 2 years ago.
You can choose different form factors (small cars, sedans, wagon/crossover/small SUVs, medium SUVs, literal pickup trucks), and basically any price tier from economy to ultra luxury high end.
Not every ecological niche was filled in the past 5 years, and some still need a bit more competition, but even with some pullback over the last year there are still plenty of new EVs hitting new categories (e.g., true three-row SUVs and minivans) that will feed into tomorrow’s used market.
And not every model will survive. The future of all-electric full size pickups looks pretty grim. Some entire companies might not survive the EV transition (looking at you, Honda). But overall, the used market will fill out with what was hitting the new market 5-10 years ago, and we’ll start to see a lot of consumer preferences start showing what the future of cars will look like.

Kinda depends on the rock, right?
California is famous for having different emission regulations. They have an exemption from the national law that they’re allowed to make stricter emissions and gas mileage regulations. None of those should prove to be a burden for anyone who wants to sell a battery EV in California, because there’s no standard that applies only in California to EVs.
