  • LFP is only typically about 15% less energy dense than NMC. You’re dead wrong about EV manufacturers moving off NMC. LFP is cheaper to make and lasts way longer. Only the US has more issue, because we’ve pissed off everyone else and getting lithium can be a potential supply chain issue.

    The tax credit didn’t get killed off until the end of 2025. Way after Amazon had already purchased the batteries from a South Korean manufacturer, that was chosen because they have a fab in the US and it was going to meet the EV full tax credit (this is well known and documented. Go see for yourself).

    You also don’t know that everyone will buy the bigger battery option. The range is supposed to be like an extra 100 miles, but Amazon hasn’t given price differences yet. If the base model is $25k, but the extended range model is over $30k, the smaller model may very well sell good. They’re just being made as city trucks. Neither battery is big enough or charges quickly enough for long road trips, so a lot of people may not care about the extra range. Depends on pricing.

    The 100k battery replacement is pretty spot on. Smaller batteries means more complete charge cycles done faster. NMC noticably degrades after around 800 cycles. The batteries will start needing replaced at 10 years and 100,000 miles.


  • Lol. No it isn’t. The batteries are only 53kw\h in size and they’re using shitty NMC batteries instead of LFP (or other) batteries because they want the full $7,500 tax credit. $500 would more than make up for the aerodynamics. No manufacturers want to use those batteries anymore because they only last like 2\5 the charge cycles compared to LifeP04, and it get even worse compared to other batteries coming out right now. Really, putting those batteries in something with only a 150 mile range is kind of a shitty move, IMO. You’ll need a new battery after 100,000 miles. Fine for a cheaper option I suppose, so long as the batteries are easy to replace and it won’t cost $5,000 in labor.

    You know it isn’t supposed to take that long. It “clicked” earlier for all the older generations due to how fucked the younger ones are. That’s why you probably didn’t buy a house before you were 25 and haven’t been going on one or two cool vacations a year. You also never bought a new car on a 3 year note (or just paid cash for one).









  • When I was 5 my grandparents got me a sapling to take home (a rental house. Totally don’t think we got permission) and planted it in the back yard.

    That was over 35 years ago and it’s now good and massive. Every few years or so if I happen to be back in that city I’ll go drive on by it, to check on my tree. Always hoping that it’s doing well.




  • I’m not anti solar, dude. I HAVE solar. Solar is a great thing. I just don’t believe it is the end all be all of power creation. I think fusion should be better. Smaller footprint. Safe, short term radioactive waste left, no battery storage needed, creates power 24 hours a day instead of 10 hours if it’s sunny. Honestly, it’s kind of a no brainer. Especially for urban areas\densely packed cities.

    Stay off trying to debate ev vs ice over this. When all the vehicles are ev, you’re going to need a LOT more solar panels and batteries to keep up. A whole lot more.

    As for the creation of nuclear waste from fusion; it doesn’t make radioactive waste like fission, it makes less and what it makes has a much, much, shorter half life.

    Plus, imagine re-blanketing the planet in all those solar panels in a 30 year loop as they age out. Solar is great for local stuff and your house. Fusion will be the ultimate energy source, so long as it can be perfected.
