Them not being capable of thermal runaway is the big game changer imo. They explode, but don’t catch fire in doing so.

I think there is more to structure level battery support that you might consider which highlights why appliances with batteries could catch on faster.
I don’t need a permit to get an ac that has it’s own battery pack. The overhead and total investment (let’s say 500 for a basic AC and 1k for one with batteries) is far far lower.
You aren’t wrong at all with your current critisism. I’m just at saying that I think the benefits to end users are sufficiently high and the barriers low enough well see wide scale adoption of in appliance batteries fairly soon l.

A couple things, and to be clear I’m really narrowly focused on appliances/ immobile applications. I don’t think these heavier batteries are quite yet ready for things like phones, drones, scooters, EV’s.
I think specifically this battery technology addresses your issues directly.
Firstly, there are actual reasons why current battery technologies are not allowed to be used in specific indoor applications, and that is thermal runaway (effectively your third criticism). Generally, LiPO’s are not legally allowed for use in permanently installed indoor environments. The reason why is thermal runaway.
Here is a video of an idiot puncturing a lipo cell: www.youtube.com/watch?v=yzBFCufUDq0
Here is a video of an idiot puncturing a sodium cell: www.youtube.com/watch?v=W1ya_ls1zkA
Spot the difference? Its the fire. The only reason we don’t currently have LiPO’s acting as stores of power for current technology is that you DO NOT WANT lithium fires to happen indoors. A sodium battery will explode (see idiot A). But it will not catch fire and will not create a thermal runaway situation.
Secondarily, appliances are already heavy. Adding weight for something like a battery isn’t an issue because you don’t need to move the thing very often. The amount of additional design complexity is small, and something we’ve basically already solved in so many ways. We don’t need the portability we would need for a vehicle or cell phone.
Thirdly, I think the complexity is trivial. Complexity hasn’t stopped producers from adding what amounts to a small computer to everything from a refrigerator to a tea kettle where literally a simple switch would do.

Yet we love devices that keep their power with them.
Curious.

I don’t agree with induction roads. Its simply not necessary and makes roads far more complicated to build and maintain.
just batteries is plenty.

It just seems like almost all very reasonable upsides.

We saw a USB pack similar to this released by a Japanese company earlier this month.
If these prove to be as viable as they appear to be, the age of oil is over, because as interesting as these may appear for vehicles, mobile-ish electronics (read, they aren’t great in terms of energy density), where they’ll shine is immobile grid scale or structural scale or immobile device scale storage.
Your oven might end up with a bank of these. Your fridge. A power wall for your house that holds 4 days worth of electricity. These have way way way higher cycle reliability than their lithium counter parts. They’re good for something like 5x-10x as many cycles. But they are heavier per unit energy. But they degrade slower.
I’m trying to not get to hyped but the bits of news of these getting into consumer technology is extremely heartening. The biggest and frankly, only middling issue, with renewables is where to stick the energy in the between times. Grid scale or microscale storage is the answer, but honestly, lithium hasn’t been a great technology for that. Its good enough to get started, but the cycle time isn’t great and the consequences of failure are high. Lithium fires arent nothing to fuck with.
As far as I know, these sodium batteries basically can’t catch fire the way lithium can. There is no thermal runaway potential.
They don’t consume (as much) hard to get, planet destroying minerals like lithium or cobalt.
They’re very young, but even in these first generations, are coming in price competitive with lithium comparables. Remember how expensive lithium was in its first generations?
We’ve already spent a few decades setting the world up to run on lithium batteries. Sodium should be a drop in replacement.
- Comment on Short attention span 1 week ago:
Its stress. You need a break, even if you can’t tell you need one. I know, because I’m in the exact same boat, and I need a break too. You and I need physical rest, time to dissociate mentally with existing responsibilities, and spiritually (emotionally) reconnect with our motivations for living.
I think its reasonable to assume these symptoms are compounded by environmental factors (like having had covid, stress, getting older, etc), but ultimately, its our own behavior to be put at blame. That doesn’t preclude the need for potentially deep recovery. For example, I was extremely burnt out 6 years ago. I made a huge number of life changes, where I knew I would be overextending myself even further, with the goal of being able to real it back in at the end to a much more simple calmer life. And it would have worked if not for the complete and total collapse of American democracy.

Shit aint free.
I mean when we were over at (the bad place), people were literally donating monthly to pay for server costs. (the bad place) in the early days was basically one giant instance.
except it didnt have a working video player. for-fucking-ever.
so I donate a bit to my mortal enemy @desalines and a bit to lemmy.world to keep the project going. Maybe 5 bucks a month between the two?

Are yall not sponsoring this project on patreon or otherwise?
I pitch in something like 1-2 bucks to desalines and a few bucks to .world every month.
