The longevity numbers on these are abysmal, though. Like nearly useless after a year.
I'm not interested in hearing about perovskites breaking efficiency records when the longevity issue isn't solved.

How about an HP NC523SFP? Keep in mind, this is HP enterprise stuff, not consumer level. Dual SFP+, pulled from server hardware. Doesn't work on FreeBSD.
Relatively speaking, perhaps. In practice, modern cars are pretty damn reliable, at least mechanically. Tons of cars end up in the junkyard with perfectly working engines.
I can't seem to find the reference now, but there are some studies out there showing every single brand is more reliable now than the best brand 20 years ago.
It's almost like forcing a majority of the population to drive a 2 ton vehicle at over 60mph was a bad idea that has no real fix. Maybe we should make some changes so cars aren't the default mode of transportation anymore?
Probably fine. Nissan's problem isn't reliability so much as being boring and outdated.
And what always gets lost in these discussions is if that old Unix stuff was so amazingly good that we should automatically assume Linux is inferior for not doing it. Even though all the old Unix vendors are basically dead now and replaced by Linux. That might have happened for a reason.
Wish they didn't. DIY opnsense/pfsense boxes are much harder for finding compatible NICs because they're on BSD. Conversely, used enterprise-level NICs often have better drivers on Linux than Windows.
There's some EVs that are integrating the battery into the frame in order to save weight. And it does save weight, but there's no way to replace the battery.
These aren't in a lab. They're being manufactured right now.
There's a toxic positivity in battery tech news. So many things only end up being practical in a lab, but the news headlines sensationalizes every single one. Its led people to believe that no advancements are coming. But the truth is that batteries improve 5-8% in kwh/kg per year, and that compounds over time to some real gains.
Well, hurry up and pull yourself up by your bootstraps.
Every time I see a headline about perovskites solar cells, I ask "what's the longevity?" Efficiency is nice, but it doesn't mean anything when perovskites degrade hard in less than a year.
The idea would be that they're so cheap that we can plaster them on any surface that gets a bit of sunlight. Higher efficiency is better than lower efficiency, of course, but it's not such a big deal when they're so damn cheap. But they have to last.
This article doesn't even seem to answer the longevity question.
