No better than what?

CRI is defined as how closely a light source matches the spectral emission of a thing glowing at a specific temperature. So, for a light source with a 4000 k color temperature its CRI describes how closely its emission matches that of an object that's been heated to 4000 k.

Because incandescent bulbs emit light by heating a filament by definition they will have 100 CRI and its impossible to get any better than that. But the emission curve of incandescent lights doesn't actually resemble that of sunlight at all (sorry for the reddit link). The sun is much hotter than any incandescent bulb and it's light is filtered by our atmosphere, resulting in a much flatter more gently sloping emission curve vs the incandescent curve which is extremely lopsided towards the red.

As you can see in the above link, there are certain high end LED bulbs that do a much better job replicating noon day sunlight than incandescents. And that flatter emissions profile probably provides better color rendering (in terms of being able to distinguish one color from another) than the incandescent ramp.

Now, whether or not you want your bulbs to look like the noon day sun is another matter. Maybe you don't want to disrupt your sleep schedule and you'd much rather their emissions resemble the sunset or a campfire (though in that case many halogen and high output incandescent lamps don't do a great job either). Or maybe you're trying to treat seasonal depression and extra sunlight is exactly what you want. But in any case I think CRI isn't a very useful unit (another reddit link).

There is already a Chinese EV that uses a sodium ion battery, the JMEV EV3.

It's a tradeoff of range vs price. The EV3 only has 155 miles of range, but thanks in part to its sodium ion battery it costs only $9220 new. Which is a price that will probably drop even more as more sodium ion plants come online and economies of scale kick in.

EDIT: even if your commute is 40 minutes long, driving 60 MPH the entire way, that range is enough to get you to work and back using a little more than half your charge. Given that it's also generally cheaper to charge an EV than pump gas, and there's less maintenance costs, I think there's absolutely a market for such a car.

Trying to create a cheap microwave burrito that's also healthy and filling seems like a pretty noble (if difficult) goal to me. Making it vegetarian also decreases its ecological impact (though I don't know whether or not Adams cared about that).

Trying to fortify each burrito with 100% of your daily vitamins was a really stupid idea though. It was unnecessary (just take a multivitamin if you feel like you need it), it made the burrito taste worse (Adams described it as "chalky"), and it was potentially unhealthy if someone were to eat multiple burritos per day (and thus receive multiple times the recommended daily dose of... everything).

An arch user defines "doesn’t break all the time" as "I have to read the news before every update and apply a manual intervention a few times a year, and there's only been like one time in history that an update made people's installs unbootable despite them taking those precautions".

A Debian user defines "doesn’t break all the time" as "I have a cron job running that periodically runs sudo apt update. I have no idea when it does this or what's changing when it happens and nothing bad has ever happened to me".

Like, the fact that unattended-upgrades comes pre-installed and enabled by default (for security updates) in Debian GNOME vs the fact that informant exists to force you to read the news in Arch before you update should tell you that the two distros exist in two different universes.

Adding on to what GreyEyedGhost said, since the year 2000 the price of solar power (per watt) has fallen by more than 50x. Because of this huge drop in price the installed solar capacity has been doubling every 3 years. That means that in the time since 2020 we've built more solar capacity than we did in the previous 20 years combined.

If that's not good enough then idk. Imagine holding any other technology to that standard. The model T came out almost 100 years ago for an inflation adjusted price of $27,000 and with an MPG of 7.5. ICE cars today are better in a lot of other ways but they are not 50x cheaper and they are not 50x more fuel efficient than that.

Huh ?

What information are you trying to convey by quoting that sentence from the article?

You can buy sodium ion cells online right now. It's not the next phase, it's here.

If the tank were made of a carbon fiber composite it would make it a little less scary. CF's high strength and brittle failure mode mean that the tank would "open up" on a seam when ruptured, but would stay mostly intact. Additionally CF's low density would mean that any small pieces of shrapnel that were created would have limited penetrating power and range.

Still I'm not sure I would want to stand next to it. At 10,000 PSI a small hole (or opened valve) in such a tank would produce a gas stream with enough energy to seriously injure or kill you (leaks in 4000 PSI steam lines can cut your flesh and create gas pockets inside you). The entire tank letting go all at once would surely create a shockwave that would obliterate you.
