That's my feeling, because this article is garbage. There's nothing special about LFP batteries. They are cheaper, last more charge cycles, can usually sustain higher charge rates at higher states of charge, but are substantially heavier, and have lower energy density both by volume and by weight.

I don't really see this as an improvement except in the low budget sector.

This isn't newsworthy. LFP batteries are not uncommon in electric vehicles. It's also interesting that this article only talks about the positive points of those batteries, but skips right over the fact that they are significantly heavier, and that their energy density both by weight and by volume is significantly lower than that of NMC and NCA chemistries

Also, it's not NCM, it's NMC. While we're on that subject, I wasn't aware of that most electric vehicles didn't include Tesla, who does not use NMC. Tesla uses NCA and LFP chemistries.

Imagine. Having parents monitor their kids. its not that hard. If I saw my kid with signal on his phone id wonder why he has it. No point in tryna limit signal. Another one will just pop up.

LMAO, also (no offense to any Police in here) but the whole keeping a key only for when it is approved to be used. 🤣 What a joke…

Just like they did with Cellebrite?

Abuse.

Guilty until proven innocent here in the US. Witnessed it first hand myself….even if you fought and bled for your country.

You’d need more than that, Western Australia 45% of all domestic rooftops have solar, we cover most of Our needs from solar, but it’s the storage that’s the issue for night time. It can be done, but battery tech needs to get cheaper and it is. In Australia you can buy a 6.6kW system with a battery for 12k USD and it would cover most house holds needs.

> Solar is doomed as a full replacement for carbon until a cheap battery (sodium maybe) that can be recharged 1000's of times and recycled can be developed.

Iron Redox Flow Batteries are being deployed at grid scale (only two 75kwh batteries to start) for the first time this year. Super cheap, recyclable, and can last 50-100 years. Now we just have to worry about running out of iron, salt, and water.

Well me hearty, when 98% of the market defaults to you that’s a monopoly. Businesses and the government largely aren’t on the others. Government shouldn’t use a private monopoly of a platform (twitter and YouTube for comma and google for finding info)that isn’t neutral for official communication.

It’s obvious we won’t come to a consensus, but it’s been nice having a discussion that didn’t include ad hominem attacks or bring up certain mustachioed men.

Good day!
