They don't get to claim the moral high ground.

True, and neither does Hamas. For that matter, neither the Israeli nor the Palestinian people get to claim the moral high ground, since both overwhelmingly support the actions of their governments. Both are in the gutter, and digging downward. A pox on both their houses, and I don't think we should support either one. I am okay with humanitarian aid to starving people, though.

There's a third and fourth reason too: 1. Fewer charges per year. It's a minor but still useful additional convenience to only have to plug in once a fortnight instead of once a week

I suppose. I prefer to plug in every time I park, then I basically never have to pay any attention to range except on long trips.

2. Fewer charge-discharge cycles per year, so the battery should last longer

Yeah, that's another side of my second reason, though cycles really only begin to bite when you get close to full or close to empty. Oscillating near the middle is fine.

Comment Re:FALSE impression - LOOK at the charts (Score 1) 214

The charts clearly show that the 100% is only hit for a few brief minutes at the top of the day with solar panels at max output. For 2/3 of the 24 hour day, those "renewables" are not even managing to produce 60%... which means that for the vast majority of the time, traditional power is MANDATORY to prevent extreme blackouts.

You're missing the point.

The point is that CA has now gotten to the point where storage is a real requirement to continue growing renewables, at least if they don't want to simply be discarding a lot of renewable generation. That is, CA has now gotten past the easy part of renewable growth, where the renewables are cutting into but not fully replacing fossil fuel generation. From here forward, it's going to be harder, and the state is going to have to be breaking new ground.

This is both a major milestone and an inflection point in the difficulty of converting.

because the renewables are getting in there for their chunk of energy supply (at the time and volume convenient to THEM) the traditional sources must adapt - which makes THEM more expensive

Even that is not enough when renewables generate >100% of consumption for significant parts of each day. Then you have to start figuring out how to store that excess production. In the short term they can probably sell some of it to other states, but as other states transition their own production that's going to become less useful, especially for solar. Time to start building out storage!

I used my Leaf quite happily for years. My daily commute was only about 25 miles, so the car could make the round trip easily. In the winter making the round trip without charging got me closer to empty than I liked, but that just meant that I shifted from charging only on the L2 at work to also plugging in the L1 at home. The only real problem was that I often got home with low enough miles remaining that we couldn't take the car very far in the evening if we were going out to eat or something. So then we'd have to take the Durango. This was in Cololrado.

Then I moved to Utah (where I'm from)... but here I work from home. The Leaf was fine for running errands as long as you didn't have too many stops, too widely separated. In a pinch, there is a Nissan dealership with a Chademo charger not too far away, just at the bottom of the big hill I have to climb to get home, so sometimes I had to stop there for 5 minutes to make sure that I had enough juice to get home -- where I had installed a 10 kW L2 charger. Two of them, actually, because then I bought a used Model S and sold the Leaf to my son. By then my lease had ended (after being extended twice) and I bought the car for a steal. In total I only paid $14k for the car.

My son still uses it to get to school and work. He doesn't live far from me and has to climb the same hill, and the car has lost some range, so in the winter he always has to stop and charge on the way home. He seems fine with that, though, and even prefers to charge more than he needs to because the Nissan dealership's electricity is free.

But if my battery has lost 10% then all the joy will be gone out of using it. I'll just be thinking about how to pay for the battery replacement every time i get in the car.

Unless the battery was too small to begin with, you won't even think about it. I normally only charge mine to 70% anyway, so the difference between 100% of capacity or 90% is completely irrelevant on a daily basis. For long road trips it's also irrelevant, since it's most time-efficient to charge to only 70-80% -- charging slows way down as you get close to full.

So, why not get a smaller battery if you rarely use the whole thing? Two reasons: First, so that losing a little capacity or charging to 70-80% is still sufficient range. My first Tesla, a 2014 Model S, only had 200 miles of range when charged to full, and that meant that time-efficient road-trip charging required stopping every 100 miles, which is too often. Second, because using the full range of the battery causes it to lose capacity faster. So, you buy an EV with a battery that's 30% larger than "needed" in some sense. Losing some of that doesn't matter.

So, you wouldn't think about how to pay for a replacement every time you get in the car, because you wouldn't plan to get a replacement, ever.

Yeah, specific battery packs can be faulty. It also depends a lot on whether the car properly manages battery temperatures. My first EV was a 2011 Nissan Leaf, and the Leaf has no battery cooling so in hot climates the batteries often die quickly. That said, it's 2024 and that 2011 Leaf still has about 60% of its original range (my son bought it from me). We live in a temperate climate, but it does get pretty hot in the summer.

Comment Re:But not practical everywhere (Score 1) 164

I live in rural America, and an EV charging infrastructure is largely non-existent. In concept, EVs have their merits, but in execution, they are not usable everywhere.

I live in rural America, and EVs are great here. Oh, public charging infrastructure mostly doesn't exist, but that's fine because I have electricity -- get this -- at my house!. I even have flush toilets, 'cause we're high class. The nearest Supercharger is ~100 miles away, but I have a garage, and a barn, and I put EV chargers in both. For normal daily driving, it works fine to just charge at home -- car is fully charged every morning -- and when I go on a long trip, well, the Supercharger network has me covered.

Works perfectly.

So you are willing to pay out another $10K eventually for a battery just so that you can plug in at home?

It's not clear that will ever be needed. EV batteries don't just stop working (barring some unusual fault); they just gradually decline in capacity, and the decline is very slow after the first 1-2 years. So expect to have 95% of capacity after two years, 80% after a decade, 60% after two decades, 50% after three, etc.

So it's just a question of when the capacity drops so low that the vehicle no longer has enough range -- but over time charging infrastructure is going to get better and better, so long range will become less and less important. Also, batteries are going to get cheaper.

So, yeah, it seems entirely reasonable to me to replace the battery in 20 years (if you haven't replaced the vehicle by then). Especially since the fuel savings over that time will far more than cover the replacement cost, even if the replacement cost hasn't come down, which it will!

Comment Re:These people are hallucinating (Score 1) 315

An implication of a physically implemented "superintelligence" would be that it needs to have much more computing power than a human brain. There are scientifically sound indicators (not proof, just plausibility) that no such device can be built in this physical universe, hence a machine that is a "superintelligence" is not physically possible.

What are these scientifically-sound indicators?

I suppose some of that may be down to the difference in the value of the change. It was worth about 2.5X what it is today back when I was working convenience store night shifts, so people might have cared more about getting it correct.

Even more, people at Starbucks are paying $7 for a cup of coffee, so they're clearly not very price-sensitive. If the customer doesn't bother to look to see whether they got the correct change, should the cashier waste everyone's time getting it right? I think yes, but I could see where people might disagree.

I know people at the convenience store got pissed when they got shortchanged, which is why cashiers who couldn't count change out got fired pretty quickly. They might last longer at Starbucks today. Especially since most customers don't pay with cash.

Anyone who IS actually valuable with a rare skillset in high demand does not fear deportation. Before you can deport them, they already have another job, potentially in a hostile country,

The fact that they can get a job in another country easily doesn't mean they don't fear being required to leave this one. Most immigrants like the US and don't want to leave it, and even if they didn't care about the US in particular they've often built lives here that they don't want to uproot. I've seen several really smart, talented people get booted out of the country over bizarre rules or immigration snafus, even with help from expensive immigration attorneys. It's stupid.

And, of course, many more are willing to be abused by their employers in order to stay. I don't see that problem so much, because although I work with a lot of people on H1Bs, my employer (Google) treats them well, pays them the same as citizens, etc. But it make sense that there is a lot of abuse in the broader industry.
