Probably way better and way more expensive.

What’s the point if they still have AMD, Intel, Nvidia, Qualcomm, etc. chips on them?
I’m a sucker for any connector that has a nice solid spring load mechanism that pops into place when properly connected. It should sound like a movie sound effect of a gun being reloaded.
I’ve also used some really nice quick release steering wheels, like on race cars or racing sims, where they have a spline connector with a tight fit and a good spring load.
The carbon free rock is replacing limestone in the manufacturing process, not the sand. Sand is added to cement, along with rocks and other aggregates, to form concrete.
From what I can tell, the way this might be bad is that the carbon free rock may not exist in significant quantity. If it does, it will be mined in the same way as limestone, so that’s just a wash not a bad thing. If the rock they need doesn’t really exist they have to buy it from someone else who makes it from readily available materials. In that case, it could be green washing, where the company can claim “our process doesn’t release much carbon compared to the traditional process” but in reality the total carbon released to create the cement - from mining to processing to pouring - could be similar.
Tbh you might be able to come back go pocket casts. They added a bunch of functionality back over time. Can’t remember what it used to be like anymore, but it works for me.
I have a free account and do have access to the filters. You can filter by podcast, started/not started, duration, etc. It may still not work for your needs though.
On one had we’ve got links to the department of energy and to Wikipedia. And just some hand waving on the other hand.
If we’re talking approaching fundamental limits, Hydrogen fuel cell is not a great comparison. A high pressure tank can only get so light, even with linerless ultra high strength carbon fiber pressure vessels, the mass of the vessel is maybe 6-10x the mass of the hydrogen it carries. To increase specific energy there you need to go to cryogenics which is a whole technology leap and has its own set of challenges.
Battery tech has been improving more than you have seen, clearly. Since '08, lithium batteries have increased energy density by 8x (https://www.energy.gov/eere/vehicles/articles/fotw-1234-april-18-2022-volumetric-energy-density-lithium-ion-batteries). The best LiPo batteries are around 0.9MJ/kg right now, but there’s no fundamental reason a battery couldn’t achieve 9MJ/kg. Lithium-air batteries could theoretically achieve way higher energy density than that even (https://en.m.wikipedia.org/wiki/Lithium%E2%80%93air_battery), and have already been demonstrated in a lab to achieve more than 5x what current commercial automotive batteries are doing.
I think the point that is counter to yours is that we are nowhere near the fundamental limits of energy density for batteries. It’s probable we are near a fundamental limit for LiPo, but the point is that battery tech improves by changing technologies/chemistries. BEVs couldn’t exist at all when the best rechargeable battery tech was lead-acid, but were enabled by LiPo. Theres most likely a type of battery you can’t even imagine that has yet to be invented that could store >10x or more energy than current LiPo per unit cost or mass.
I don’t think closing threads is a great idea or in keeping with how this all works. I think it’d be nice to be able to mute a thread as an individual, but by its nature these discussions are open and shared with many instances. If we close it on kbin.social, other kbin instances, lemmy instances, and even places like mastodon and pixelfed could keep discussing, if I understand activity pub correctly.
And we’re already posting screenshots of reddit posts that are screenshots of tiktoks. Awesome
Sounds like they fucked up training the AI then. For a user it doesn’t matter whether the AI is designed poorly or trained poorly, it’s behaving poorly.
