Well, at least that would still be some progress....
Slashdot now the home of Luddites? "Why do we need a SPACE BASE?"
A lot of people write off space 'competition' as just militaristic dick-flexing.
You do understand where ICBMs came from? There isn't a serious question that space is absolutely now a context for global-state competition; it's not dick-flexing to recognize that this will shortly expand from orbital space to really the entire cislunar sphere.
It is, in fact, one of the generally-undisputed roles of government to try to recognize a strategic vulnerability and address it proactively.
Further - and this may end up getting modded to oblivion as recounting these facts is distasteful on
SpaceX is multiples cheaper than competitives in launch cost per kg - $1500-$4000 vs $18k alternatives vs $54k NASA
To suggest "SpaceX is a slush fund from Trump to Elon" makes no sense. I want our govt to be using the CHEAPEST AVAILABLE LAUNCH capability. Are you asserting they shouldn't?
BlueOrigin is well behind but commercial launch development is *significantly* driving down costs, that's unquestionable.
As far as "publicly funded"
"It's accepted that Lithium is not rare."
You and I and some may recognize that, but the media organs have been screeching for some time about China's "monopoly" on rare earths and the west's "vulnerability" for a decade or more.
I can't count the number of times I've had to explain that yes, in fact the US has world-leading deposits of lithium. (as much as 40 million tons of reserves. vs Chinas 10)
"this process is welcome. As it has a dramatic reduction in toxic residuals from processing"
Fully agree, this would be a wonderful opportunity. Not only does this absolutely mean less toxins anywhere, this would open the chance of actually doing lithium recovery domestically (it doesn't really matter how clean the process is, I expect crowds of Earth Firsters gathering to oppose any such industry, regardless; this would just mean it has a reasonable chance of moving out of the morass of environmental protests...).
But why keep evidence of embezzlement at home?
Yeah, I think they forgot to include "stupid" in the long list of his faults.
I hate to defend the UK, and there have been some serious mistakes made, but nobody is in jail for hate speech. It's always something like harassment or credible threats. In fact, a recent case demonstrated that even criminal damage, throwing someone's phone on the ground, isn't a crime anymore, unless there is very strong evidence that it was damaged by that specific action. That incident was preceded by months of harassment too, and the guy got away with it.
The problem is American exceptionalism. The idea that America must be better than everywhere and anywhere else in the universe (including all of the black holes) is drilled into them from childhood. The problem with this is that things have become so bad in the US they now have to engage in huge, collective fantasies to make other places seem even worse than the US.
As mentioned, no-one in the UK is in jail for hate speech. That isn't a criminal offence, they're in jail for actual offences such as threats or harassment (yes doing it "with a computer" does not magically make it not a crime). Committing a crime with a hateful motivation is a modifier in court, known as a "aggravating factor" and often leads to a harsher sentence (especially if they don't even fake remorse, which is a "mitigating factor").

It's not 'offended' when some naive biologist uses this workflow engine and has a protein name interpreted as a date and then expects me to be able to fix it because they associate me with the computer.
Other related terms:
* Pseudo-quotation: Putting a paraphrase or the general "gist" of someone’s argument inside quotation marks, rather than their literal verbatim words. Acts structurally like a quote, but semantically is a summary.
* 'Fictive Direct Speech (Esther Pascual): The structure of direct speech used to express a non-conversational concept, such as a belief, attitude, or general stance.
* Constructed Dialogue (Deborah Tannen): Used for "reported speech" - when people "quote" others in conversation, they are rarely reciting a literal transcript. Instead, they construct dialogue to dramatize a stance, represent a general attitude, or summarize a complex argument in a digestible way.
Sneer quotes (also called scare quotes) are similar, in that they summarize a person's stance, but have the distinction of also being dismissive of the person / stance as well.
That's not what "sneer quotes" do.
(And the quotes in the above are neither direct quotation nor sneer quotes, but use-mention distinction quotes, which let the sentence "know" that the thing in the quotes is the word/phrase itself, not what it refers to)
(And the quotes in the above are signaling quotes, to convey that a word is being used in an unconventional manner; it's a "clever" way to distance yourself from the word)

Yeah, I've been using canisters, and they're expensive and a chore (and because of that, it encourages me to give the plants much less than would be ideal).
The basic process is potassium carbonate/bicarbonate swing absorption. Potassium carbonate absorbs CO2 (and H2O) from the air at low temperatures , forming bicarbonate, but the bicarbonate emits CO2 (and H2O) at high temperatures. So the system has two modes: one, a powerful radial blower blows air through a pumice bed packed with potassium carbonate so that it absorbs CO2 (more specifically, it first absorbs H2O, and then CO2); and in the other, the fan is shut off and a PTC heater turns on to heat the pumice bed.
I'm trying to make the whole system as passive as possible. Since the fan is so powerful (you have to move a LOT of air to capture CO2), it's designed to blow dampers shut or open that control its path, while a different path opens up when the fan is not on. The PTC heater being on will automatically force the fan off. I've also set up (cross my fingers whether it works...) a weight-based system to control fan/heater switching. The core is PPS-CF (super heat tolerant) and mounted on springs, so it should move downward as it absorbs more moisture and CO2, and when it's full, it should force the fan off (even if my greenhouse controller hasn't requested CO2, aka triggered the PTC heater). And when the PTC heater is on, it rises from losing H2O and CO2 mass, and if it rises too much, that triggers a switch to force the fan off.
I'm also perhaps overcomplicating it and making a rod for my own back, in that I've designed it so that both modes have the air travel through a system of (also 3d printed) heat exchangers (in general, heat exchangers working with air have no issue with being made of plastic, because the heat flow from the air to the wall is slower than heat transfer across the wall). So these are big and made of multiple parts, in order to not slow down the airflow from the blower too much. But the idea is that the CO2+H2O flowing outwards cools and deposits H2O in the exchanger (then a secondary heat exchanger re-heats it to drive the convection force), while in capture mode, the incoming air can use that H2O instead of having to rely just on atmospheric H2O (which is viable, but does impose a capture delay). And of course, it helps maintain a warmer temperature inside the core on very cold days that might slow down the reaction (it's designed to be able to be mounted outside; the bulk of it will be printed in ASA).
Right now I'm in that annoying phase of prototyping where you print chunks of parts out, see if they actually print right ("whoops, there are supports in this area, but I CAN'T REACH THAT!"), actually fit together right (for example, dampers not jamming in their paths), the non-printed parts actually fit (I keep screwing up the mount for the blower, lol), that sort of stuff.
Dunno, but it's a fun project, and hopefully it will work
Of course you can't flap your arms and fly to the moon. After a while you'd run out of air to push against.
