A world where all cars are EVs will need many changes from the world today, but we have decades to make those changes. Take the grid capacity problem. Household electricity usage has already increased by a ton throughout the history of electrification. The grid can adapt. It takes a long time to build out this sort of infrastructure, but we have that time. Grid capacity needs to increase by 20% over the next 30-50 years? Ok, and?

The article also can't seem to make up its mind about whether EVs are suitable for long distance travel. It talks about how highway charging stations will have to be much larger than gas stations because charging takes longer. Then a few points down, it says that range and recharging time are incompatible with charging while traveling. Which is it? If it's incompatible, then you don't need highway charging stations in the first place....
Mandatory transponders on drones might not be the worst idea. I'm sure soon enough police will learn to look for the signals.

Many drones are 2.4ghz something something. What if airport police monitored the frequency around the airport? Then use signal finding to capture controllers?

Oh, I agree. I was saying that today's "autonomous" vehicles have professional testers ready to take over. That certainly doesn't work in the general case. You can only automate so far until you have to turn over control entirely and that's a long way out. (Google has effectively recognized this with it's steering wheel-less vehicles.)

Curbside chargers.
I have an electric car, a leaf. I also have solar power from Solar City.

I live in sunny MA, where in the winter we average 15kWh generated to the summer we average 50kWh. My commute is 60 miles per day which is around 6-8kW depending in traffic and weather.

Also, my local power is a mixture of nuclear and wind.

So. Can we please stop rolling coal burning power plants into the electric car equation as if it is universally applicable.

The car was affordable: $12k second hand. The solar was $0 down and half the national grid per kW. My commute is at the edge of viable for a first gen electric car (really looking forward to the 200mile range of 2nd gen).

I do the vast majority of my charging is at home. My only issue is that the current system (sic) takes DC power converts to to AC only rectify it back to DC in the car. There is still a need for charging stations, but for rare 100 mile journeys. Drive 80 miles charge for 20 minutes, drive 80 miles. 2nd gen it's 160 miles, charge for 40 minutes. We have family in Western MA, which is 150 miles away. With a 200 mile range we'd do it in a single charge and recharge at their house. The use of a charging station is really rare, not part of the routine of ownership, like it is with ICE.

We don't have the infrastructure? We don't need the infrastructure. You can run an electric car almost entirely from energy reclaimed from the environment around your house. It will even store it for you in those handy, replaceable lion batteries it has, solving some of renewable energies gnarlier problems.

Whilst I understand that electric cars don't work well for people who travel more than 100 miles without a 20 minute break, that number is about to shift to 200miles... and that is virtually nobody. The infrastructure problems are solved by local generation (either municipal renewables or home solar). The recharging problem, even at 100mile range isn't a problem, you just charge it at the end of your journey.

The adjusted price reference you made is axiomatic. Adjusted prices simply subtract the dividend. It does not reflect market value. You'll notice the open on the day after the dividend, the stock actually went up $0.40 from the closing price.

When shorting, you only pass the dividends through. The company sends you the dividend, you send it to the original owner, you could still profit from the drop in share price.

> Only if you redefine the word "freedom".

No. The GPL removes my freedom to sell something that I've created.

> The only difference is that the developers don't have the "freedom" to enslave their users.

This is where I think your entire argument falls apart: Offering users the choice to buy my software is not enslaving them. If it is, then so is the GPL because it's a choice that users can buy into or not...just like the choice that the GPL offers to developers.

You can't have it both ways. If commercial software "enslaves" users by simply offering the users a choice to buy the software, then the GPL must also be enslaving developers by simply offering them a predatory contract.

Cycles per byte is pretty standard for crypto algorithms, and tends to give consistent results across an architecture. It is usually measured with dynamic frequency scaling disabled.

Do you have a source for use of AVX2 automatically reducing clock frequency? I found this:

"Because Intel AVX instructions generally consume more power, frequency reductions
can occur to keep the processor operating within TDP limits. [...]
Performance of workloads optimized for Intel AVX instructions can be
significantly greater than workloads that do not use Intel AVX instructions even when
the processor is operating at a slightly lower frequency"

Which seems to indicate that it would only trigger when you're doing a fair amount of work with it, which should be giving you a total performance benefit.

There's no particular reason you can't install curbside chargers. It's just a matter of convincing the powers that be to allow it, and that is just a matter of EVs becoming common enough for there to be demand for it.

I still think JetBlue was a better fit. Alaska's a west coast, all 737 fleet. Now they own another west coast airline (i.e. they overlap) with a ton of Airbus. Alaska's probably getting something good for their $2.6b, but I haven't figured out what exactly.
Problem 2:

Electric cars are charged at home most of the time. Let's assume that it takes 10x as long to charge a car at a supercharger compared to filling it with gas. (3 vs 30 minutes). But if you charge at home 90% of the time, then refueling stations can be the exact same size. And I'm fairly sure that people will be charging at home or at work much more than 90% of the time -- it's probably closer to 99%.

I think the OP is overselling the following problems and/or failing to understand the problem EVs are relevant to:

1) Grid strain - By the time EV cars are popular enough for this to be an issue, installed home solar capacity is likely to be large enough that it is likely to look more like this:

2 kW worth of solar panels
1 Battery Pack (possibly interchangeable with the car)
Battery pack is drained when you get home and charge the car.
This will cost you ~$15,000 which is cheaper than the car and will last ~20 years (minus the battery pack which you'll need to replace every 5-10 years). This might go as low as $7.5k depending on technology improvements, incentives, sunny days, etc.
On cloudy days, it'll just charge from the grid over 6-8 hours while people are at work.
You'll want a system like this with 1+ EVs simply because you'll be using enough power it'll start making financial sense in most of the US.

2) EVs are primarily commuter cars so as long as their battery back lasts long enough to return home, it'll work. The rare instances where you'll need to recharge at a station will largely be irrelevant for day-to-day activity. Cars used for long distances ( 180+ miles ) regularly will likely remain hybrids or fossil fuel for decade(s).

4) Sharing will largely also be a non-issue since even when utilization goes up, we are talking ~3 hours of drive time to ~1 hour of charge time. You'd need to have greater than 50% utilization before charge time is likely to create issues. Similarly, as tech improves, that ratio will improve.

6) This is largely solved by the fact EVs are primarily going to be local commuter cars. Replacing commuter cars, in and of itself, is a worthy goal as it improves city air quality substantially which is linked to problems like asthma and cancer. I honestly don't care if long distance trucks which largely are spending their time in rural areas remain fossil fueled. I care about city air quality.

The usual opinion is that they all got rich with state contracts building stupid and expensive things that young kids would do in no time for nothing.

As a government agency, of course one would not prefer to hire kids, but these countries, they have good IT persons, they have universities that are struggling with funds and finance(as education is for free there and state universities are way beyond the private factories of diplomas that are known as private universities).

Instead of throwing that money, they could have helped education and develop infrastructure in the same time. Nobody has bloody consciousness any more!

Their core point was if you're discussing people who buy new cars, you're already skewing away from the poorer demographics. People spend less on average to buy a car, than they do to buy a new car.

The tesla 3 is a little above the average price that people pay for a new car, among the fraction of people who buy new cars. Which most people don't do.

Let me know what you think! I'd be happy to hear from you.

That line of hyperbole also justifies ignoring any value or good the state can and has provided.

If that infrastructure can be provided without the state, why hasn't it?

You are positing a hypothetical system that exists without taxes against a real, concrete system that exists and you take part in everyday. That system right now is dependant on taxes and you're throwing it out for a nebulous ideal world that is stateless and exists only in your head.

> I want nothing from the state except its utter annihilation. By choice, I take nothing from the state, and never will.

Do you drive on public roads? Enjoy protection from crime by the police? Enter buildings and eat at establishments that are inspected for your safety? Ever have to use the state to uphold a private contract? Have you used a telephone, cellular or landline?

Do you use the internet?

How can you realistically say you take nothing from the state and never will?

If you are as serious as your rhetoric, there are virtually stateless places in the world where you can actually live out your dream of taking nothing from the state. Areas of Somalia are among them.

I want public transport and walkable cities to win over electric cars. A lot of people take the need for cars for granted, and gush over the electric car future as optimum. This means that their transport utopia is something where you have these wide streets, click a button in your phone, and an Uber-Tesla picks you up and drops you off anywhere.

For me, this is the "faster-horse" of transportation.

I want more radical changes towards walkable cities with more space for people and less space for vehicles. Roads take up an insane amount of space, and self-driving electric cars don't make things much better.

Well, the stock price might have changed because of some news or general market sentiment. I guess I could have found a better example, a stock where the dividend is much bigger (percentage-wise), the effect would be much clearer then.

No, shorting doesn't work that way, obviously. "Shorting" means you sell he stock, so the new owner gets the dividend, not you. That's one reason shorting equities is very risky long-term.

Quite so. The Honda Accord, or Ford Focus family car that takes the kids to school, a 30 mile daily commute and a few trips to the shops is the low hanging fruit. They're easy to replace.

If you need something to haul a big caravan for holiday, or trailer for a move. Just rent - the rental shops will expand to fit nicely. Probably a nice big diesel.

The v8 offroader that actually works offroad, the truck, and shipping are on diesel for the forseeable.

I don't even see the space requirements to cater for EVs charging needs as much of an issue. We already have service areas on motorways in Europe. Huge spaces with a petrol station in the far corner. We'll have to adjust to 500 mile journeys including a couple of rest/coffee breaks. If you have young kids they already do. Only difference is plug the car in before going inside.

We might have to resurrect a few diners (with charging) along the way on rural or non motorway roads. I think I like that.
