What nobody talks about is that much of the lithium electrolyte in lithium ion batteries is in the chemical form of lithium hexafluorophosphate (LiPF6). Burning produces nontrivial amounts of hydrogen fluoride and clouds of hydrofluoric aci

"Neoliberalism" is Reaganomics, a series of beliefs about the world: * The government is generally the problem [with our economy], not the solution to our [economic] problems. * Low taxes, low regulation, and low barriers to trade

I appreciate the comment. What obstacles remain in the way of taking over the commercial market?

Specific corridors in the US are quite populous and quite ready for modern infrastructure. We just aren't in the mood to pay anything for it, unless it's more highway lane-miles.

We used to call this an "Industrial policy" or an "Economic development policy". Back in the golden era when a strong labor movement coexisted with a Red Scare. 78 years after Taft-Hartley and 44 years since PATCO, not

No. You're not. Blind people are. At least, insofar as we still have the ADA. One thing these companies are doing is charging blind people extra. Phrase it that way and you can maybe move some policy levers.

Yes. Sure. But before the mining operations? Probably not very polluted. It's the mining doing the polluting, not the belt of pyrite simply existing.

Phone batteries are lithium polymer pouch cells, the least durable type commonly used. Car cells with lithium ion NMC cylindrical cells are much better, and LIFEPO4 in turn is several times more durable than that. You would be wise to insi

I'm not sure the belt of pyrite is best labelled as the cause here. It might have something to do with the inferred activities of Rio Tinto, a transnational corporation that is one of the largest mining firms in the world.

This seems backwards. The tailings do not become nuclear waste when we decide to use them for something.

I don't see that accommodating this behavior is prosocial or technically desirable. Can you think of a use case? All sorts of bots want this sort of access, but whether there are legitimate reasons to grant it to them on a non-sharded

Farming does not need to be that way. It's very amenable to electrification. Long haul aviation needs high energy density. You have heard critiques about farming that focus on very specific uses of corn and soybean under conventional

Yeah. Except it isn't so unbelievably terrible on both capex and opex as mechanical DAC.

Aviation fuel has a trivial replacement in renewable biofuels, and three nontrivial replacements in liquid hydrogen combustion, liquid hydrogen fuel cells, and for short flights in battery power.

I had a wide panel at one point after a statistically unlikely health event. It was something like 300ml of blood spread over ~40 vials. They tried to charge me $7500. It did lead to a diagnosis.

We have a rather high overhead ratio in play. 1.1 million Physicians made a median salary of $239,200 in 2023, or around $263M. U.S. health care spending grew 7.5 percent in 2023, reaching $4.9 trillion or $14,570 per person. That's a

This is not obvious to me, and nor should it be to anyone who didn't program these AIs (and it probably shouldn't be obvious even to the people who did). I think you both should try testing the hypothesis and present your results
