Right. Out of the 330 million people in the US (not counting the broader market, there's "nobody" who wants a gun that can't be accidentally picked up and used by their young children or an intruder. Literally "nobody". Yeah, totally believe you.

They have a niche. You want to prevent them from filling it.

Actually, that is a concern. Li-ion batteries don't have lithium metal in them unless something goes wrong. Lithium-air batteries always have lithium metal in them, by design.

In practice, you'll probably see a bit of the energy density given up in order to beef up the casing to prevent rupture/fire.

Thankfully, lithium-sulfur batteries don't use lithium metal, just lithium polysulfides. The max energy density isn't as high, but it's still quite good. They're already on the market, albeit in small quantities for applications that require the absolute highest rechargeable energy density (mainly aerospace).

Yes, cue the standard "Batteries haven't advanced!" stuff from people carrying around cell phones with significantly more amp hours in a smaller battery profile than the last generation phones that they owned.

News flash: every time a new tech advance makes it into a product, they don't mail a letter about it to everybody who read an article about it years earlier. Example: hey, remember all of that stuff about breakthroughs in silicon anodes several years back? Yeah, they're in batteries now. Even Tesla is starting to use it in their higher-end packs.

It's good for the NAO. When you're pushing the boundaries, anything over 50% is good.

For long-term climate models, things like the NAO average out across many years. For short-term weather forecasting, you have a week or more before the system diverges enough to cease to be useful. But it's tougher working on those in-between scales.

Should be well worth it in terms of things like planning for agricultural products, natural gas supplies, etc.

The real issue however is that they've validated it with hindcasting. Which is certainly something, but isn't as ideal as you'd want. It's trivially easy to fit any arbitrary past dataset to a statistical model if you have enough parameters that can be tweaked, but that doesn't mean that you're actually capturing the underlying dynamics. That said, from the sound of it it's built around a physical model, so that increases the odds that it actually is, rather than just fitting to some arbitrary curve.

I used to follow some of what The Jester wrote. There are a number of people out there who think he's overrated, more brag than anything else. Still, I saw some pretty clever things out of him. For example, at one point he was going after some other hacking collective (I don't recall which one), and he announced a successful attack against them and posted a list of all of their names and real IP addresses. Only, the list wasn't real. Instead, anyone who tried to download the list had their connection logged and probed, an exploit used to trigger the computer to make a (real) TCP connection back to one of his computers, and a number of automated attacks launched against targets it considered particularly suspect (for example, if there was evidence of being logged into a known member twitter account). I.e., it wasn't actually a list of suspects, it was bait to build a list of suspects. I think he did the same trick with QR codes later.
