Comment Re:Just saying (time and heat) (Score 3, Insightful) 124

Technically, it probably is being subjected to that temperature for a small fraction of a second.

The confusion here is "temperature vs heat." You can have incredibly high temperatures in things like plasma, but the moment a thin plasma touches a solid surface, it transfers that very small amount of heat to the metal, without any real damage.

If you wave your hand quickly through a candle flame, for a fraction of a second you're subjecting your skin to 2500 F or so - without harm. If you move a stick through that same flame at a slower speed, you'll coat the stick with a thin layer of soot - without catching the stick on fire.

They "determined" that it was a wetland - but it wasn't.

It was a big flat stretch of sandy ground that occasionally (every few months) had water flowing over it for a short time (i.e., when it rained a lot the water drained across it to the lake). This fit absolutely zero previous definitions of "wetlands." It was a gross overreach by some bureaucrats, who needed a nice hard slapdown to make them stop.

The EPA has also claimed that other places were covered under "Waters of the United States." For example, a ditch. That didn't drain to anywhere else. That was just big enough to float a canoe, maybe. And no, that's not an exaggeration.

For reference, "Waters of the United States" was supposed to be about _navigable_ waters like lakes and rivers, not every creek and pool they can find (or imagine).

Basically, the Supreme Court decision was "stop trying to expand your powers through BS and fantasy."

Comment I worked in a computer lab once, long ago... (Score 1) 119

I had a whole bunch of undergrad programming students convinced I was a genius.

They'd ask me for help. I'd walk over and look at the code for a moment, and say "you left out a parenthesis."

After a bit, they'd curse and fix the problem they finally found.

(I was counting the left and right parentheses, and if the numbers didn't match. Yes, that was the whole trick. They wouldn't remember if I couldn't see the fix, but they were in awe of someone who could "find the bug" in just a few seconds.)

Definitely.

If we follow the (incredibly optimistic) roadmap to widespread use of electric vehicles, we're going to need a LOT of lithium. And other elements, from nickel to cobalt to the rest of the long list that goes into that sort of tech.

As in "three or four times as much mined per year as current production."

So we either open a lot of big lithium mines, or we don't get that many electric cars and trucks any time in your lifetime.

Of course, if we don't start building even more electric power generation, the cars would be a waste of time...

Comment Re:Old equipment... (Score 3, Informative) 73

Except, of course, the equipment that used R-12 and R-22 is mostly gone already in the developed countries, and the leftover machines that still have some in them are getting rare. Nowhere near enough "careless scrap" left to make a difference. In the US and some other nations, R-134a has been the major viable option for replacing R-12 for quite a while now. R-22 is still used in developing nations, though.

As the MIT study pointed out, some of those old banned refrigerants (R-11) are still being made in China, "off the books." Other reports show that India has been making some old CFC versions, too.

Of course, the other (positive) thing that isn't mentioned in the story is that we've been seeing marked improvements in the ozone layer, which shows the original claims were a bit overblown. You see, those refrigerants are very long-lived in the atmosphere, and the 1980s predictions claimed that we wouldn't see _any_ improvements in the ozone layer until at least 2050, and probably closer to 2100. That was all predicated on "shutting down the old refrigerants completely with zero new production." Which (as we now know) didn't happen.

Here's one for you - not a paper, just the BBC:

The Wuhan labs were doing gain-of-function research on bat viruses, funded by the NIH (through a group called the EcoHealth Alliance). This was admitted, publicly, by the NIH in late 2021. No study needed, this is just a plain fact.

Note that the letter which showed up denying any such research was organized by the guy who ran EcoHealth Alliance, and almost all of the people who signed on were financially tied to the Wuhan lab - basically "this didn't happen because we'd be in trouble if it did").

Fauci denied this ever happened - which is just a plain old lie. Then he said that the gain-of-function research wasn't "really" gain-of-function research, which was also a lie.
