The summary implies that remote deactivation is not that difficult, that does not appear to be the case.
I'm not really familiar with Tesla vehicles, do they have remote deactivation? Does any other car manufacturer have that?

I'm not familiar with the iPhone setup, but that is simply not realistic with Android systems. Android devices come with a number of apps providing core functionality, Samsung Android devices come with an additional set of apps providing alternatives to the ones Google supply (and some of them are actually better).
I find it annoying that I can't delete apps from either set, apps which I don't need, don't want, and only notice when Play Store updates them every few days. At least crap like Facebook, Instagram and TikTok are not in that list - they were on a previous phone and all I could do was "Force Stop".

Actually, what will happen is that people will move away from places that do this, or they will continue to drive, but more slowly, or they will ignore the speed limits and pay the tickets.

The only way to shorten trips is to increase density, and that can't just magically happen.

Walking and biking are fine if you are only a couple of blocks away from where you are going. They don't work for long distances. So they don't solve the problem, either.

You either have urban density or you don't. If you do, then cars don't work very well. If you don't, then alternatives don't work very well. There's a grey area in between where neither one works very well.

I'm thinking about my rural hometown in west Tennessee, and imagining middle school kids biking to school for up to an hour each way while carrying books, musical instruments, gym clothes, etc., and I'm laughing at how well your "magic cure" would work. It's the sort of thinking I'd expect from someone who has never lived somewhere with fewer than half a million people.

+1. As soon as you get out of the core of Paris and its inner suburbs (Hauts-de-Seine), a lot of metro Paris is suburbia with zero-lot-line single-family houses.

Mind you, it's not "a hundred houses all alike" suburbia, because it was built up before folks started doing that sort of mass development, but it's still suburbs.

I think you missed the joke, which was that you can delete two words from the quote and get "I believe you are a racist."

Bets about whether they stop working with HomeKit in February of 2026?

The forecasters don't know where you'll be when it matters. That's why it's your job to look up the data yourself.

Why do you say that? TV forecasts are averages over a region. That's by design. Do you really want the TV weather presenter to rattle off rain and temperature and humidity numbers for every block in every city in the whole state you live in? No, they just give indicative data. It's not going to apply to you. It's a guideline.

If you want to know if you're going to be rained on, go get a radar image map with rain data updated every minute, and work out if the clouds will cross your street at the exact moment when you will be standing on it.

Just got email yesterday from Belkin, to tell me Wemo devices including their hugely popular Wemo mini plug and Wemo wall switch, outdoor switch and 3-way switch were on a list to be shut down in January, 2026. They're yanking the cloud server support required to make them work, and saying the only thing they'll still do after that is work on a LOCAL network via HomeKit.

It's not just Apple. Any of these vendors of "smart" devices get to dictate when they kill off the functionality. If it requires cloud servers, then all you did was buy some hardware that works with THEIR systems, on THEIR terms and conditions.

I use an Arlo video doorbell on my front door, and initially? I was fine with not paying for their optional monthly subscription that allowed uploading video to the cloud. I was content to use it so I could view live video when someone rang the bell, and to get push notifications when people walked within range of it. Well? After some relatively recent update they did, it seems I lost the ability to configure the zone the camera monitors for motion. They just monitor the whole darn thing if you don't pay for their subscription to "unlock" that capability. Worse yet? There's nowhere in their software to configure it to just stop alerting for motion. I had to suppress it on my iPhone app via the phone's own application settings.

It sucks but I don't see any alternative except buying only devices that give YOU full control over them on your home network. And a lot of those reduce the usability and convenience vs ones utilizing the "big cloud" offered by players like Apple, Google or Amazon.

In practice, storing energy for a longer period of time is basically never done, with the only real exception I can think of being space travel. And it's not how long the storage period is that matters. It's how quickly you need to get the energy when you're done. Sure, if you store a year worth of energy in a day and dribble it out over a year, a tiny fuel cell and a huge tank is great for cost. But literally space travel is the only practical application of that. For every real-world application other than space travel, you need to be able to dump the entire contents of the fuel cell in at most maybe five to ten times the period of time over which it was built up, if not less. That means either big fuel cells or a lot of fuel cells.

See above. And to that, I would add that converting electricity to hydrogen with electrolysis of water and back is likely to result in a loss of somewhere around 60% to 70% of the energy that you put in. So even if you somehow manage to find some rare edge case (e.g. trying to do solar in Alaska or something similarly nuts) where you really do want to store power long-term and spread it out over a long period of time, the loss of energy is still going to be around 5x as high from fuel cells as lithium ion batteries even factoring in the self-discharge rate over several months.

And that's before you factor in the additional losses from having to pressurize the hydrogen, which adds further the losses. In fact, you'd actually be better off building air tanks and pressurizing them and using the air pressure to turn turbines than doing electrolysis, pressurizing hydrogen, and dumping it into a fuel cell. That will give you a loss of only 25% to 50% of the energy that goes in. Sure, it will take up more space, but you won't have hydrogen making the metal brittle after a few years, requiring you to replace the whole system over and over again, so it makes *way* more sense.

When I say that IMO, there is literally no case where hydrogen fuel cells make sense other than space travel, I mean that. It is utterly terrible efficiency-wise, so much so that almost anything is better, including things that are way simpler and cheaper than hydrogen, like a giant air tank and an air turbine.

I would still expect it to be less efficient than electric arc furnaces, but maybe not, so I'll grant you that this might be a very narrow use case, solely because burning the fuel source is actually important for that. :-)

Fuel cell efficiency is at best about 60%. So no, you do NOT have 80% round-trip efficiency, unless you've found a way to violate the first law of thermodynamics.

60% efficiency times 68% is 40.8% efficiency. Yeah, that's slightly better than 34%, but in much the same way that a s**t sandwich is slightly better than s**t. :-)

And this will still be capable of running on natural gas, which probably means it won't be optimal efficiency-wise for either fuel.

The losses from electrolysis alone make it a bad idea, even if the next step were 100% efficient. It just gets worse from there.

The basic rule is: don't do the crime, if you can't do the time.

Copyright exists, for better or for worse. It's no excuse to claim you can't determine copyright attribution because of the scale of your stash. This is true for anyone, whether you're a company looking to infringe for profit, a nonprofit looking to infringe for humanity, or a person looking to infringe for personal convenience.

Go kick the butt of the supreme courts who impose rules if you don't like the status quo, or go live in a country where the rules are different. There are some.

All you achieve when you act like a scofflaw and a whiner is that people dismiss you, quite rightly. Generations before you managed to follow the rules,. The problem isn't the copyright law per se, the problem is you are not doing your part in changing the law, citizen. It's your job to leave your country a better place than you received it.

You forgot that this is about gas turbines. They're going to BURN the hydrogen. Divide that 68% number by two, and that's still probably wildly optimistic. More realistic numbers are probably more like 20%.
