R-12 did not take dominance over R-11. Until they were both banned, R-12 might have been more commonly used in lower temperature refrigeration, but R-11 was the most common refrigerant used in water-cooled centrifugal chillers and R-22 was the most common in positive displacement (piston or screw) air-cooled systems.
Back then, we had MUCH more manufacturing here in the US, we could not only come up with the ideas, we could BUILD it then.
We had more manufacturing jobs, and probably more manufacturing, but we're still the world's no. 1 manufacturer (maybe no.2 by now). It's just that we've given up on manufacturing the cheap crap that can be made cheaper in cheap-labor countries, and we've automated away many of the rest of the jobs. (Automation, by the way, has given us very high labor productivity, which is one of the reasons labor is so expensive here.)
Yes, China steals a great deal. BUT, that does not mean that China's innovation is not up and coming.
According to someone I know who lived in China for a few years and visits frequently (his mother-in-law is a Chinese citizen), we don't have to worry about China out-innovating us. Their culture is too much about staying in line with the group-think and out of trouble with authorities and not individualistic enough for the risk-taking type of innovation that happens in the US and other developed, democratic countries.
Even if true, this, of course, could change in the future.
If the doctor even suspects a small chance of melanoma they are going to biopsy the tissue and send it to pathology where the pathologist tells them what it really is to the best of out knowledge. No dermatologist is going to treat a melanoma without a biopsy. The only important detail here is that the number of false negatives be as small as possible.
From personal experience, this is true. Diagnosing from a single picture is just wrong, other than to alert to the obvious cancer, in which case a biopsy will still be done before treatment. If the doctor decides not to remove something, they will have you come back in later to compare and see how it might be changing. And even when removing a mole that the doctor is absolutely sure is benign, it will get sent for a biopsy; to do otherwise is considered malpractice.
Middle aged is generally defined [merriam-webster.com] as 45 to 64.
That would make a 44 year-old a young adult, which I won't go along with, even if they would be young compared to me.
Childhood is 0 to 18, young adult about 18 to 36, middle age 36 to 54, mature adult 54 to 72, old person 72 to 90, and borrowed time 90 and up.
Ok, I know that's more arbitrary than accurate, but still better than saying a 64 year old is middle aged - I'm 62, in relatively good health, and I'm definitely not feeling middle aged anymore.
My thoughts are similar.
If a very high percentage of the streamers are male, and very few streamers make real money, then those few top earners are probably male, and there is a good possibility that those few skew the averages.
The questions are there on the website linked in TFS. They ask if students are taught coding / programming, and specifically state that does not include HTML, CSS, or use of applications. Not that it would prevent clueless people from getting it wrong, anyway.
Class action doesn't seem like the best option, though, as lawyers are typically the only ones that win.
So having dozens or hundreds of trials (or, in this case arbitrations) with lawyers for each one would be better than a class action with a only few lawyers involved?
Even if you go to "real news organizations" for your news, you're going to get biaised opinions and "facts" aligned with the parent company's CEO political choice.
You're conflating Fox News, MSNBC, et. al. with news organizations.
Real news organizations, such as the better news papers & magazines, report facts and leave the editorializing to separate pieces.
Most "real news organizations" tend to promote whatever gathers the most attention, almostt regardless of politics.
Do they not plug airplanes into "shore" power when parked at the gate?
Yes, planes are typically hooked up to power (and HVAC) at the jet bridge when they dock; running on jet engine power is terribly expensive. (When planes are in the air, the electric power is often generated by turbines that run on bleed air from the jet engine compressors) The electrical hook-up requires specialized converters and wiring, as most planes use 400 Hz power.
And as far as the GP goes, what is "the same fuel everything else on the airport runs"? I've been involved in the design of fueling systems at airports. The jet planes use jet fuel. Most trucks and cars use gasoline or diesel. Baggage carts and the like are often electric, sometimes propane. And aircraft tugs can be electric or diesel.
18 MW is the capacity of the emergency generators being installed at O'Hare airport. And they have enough diesel on site to power them for at least 48 hours (I doubt the batteries would last that long.), and can get more diesel delivered if needed.
18 MW is large compared to the needs of a lot of buildings, but not much on the scale of a grid.
So you're saying that a Democratically controlled congress and a Democratic president got together and *agreed* to pass a law but not enforce it?
It was a Republican majority congress at the time (though many Democrats voted for it, too), and it was never signed by the Democratic president (though never vetoed by him, either).
tl;dr version: This law is stupid virtue signaling.
Actual TL;DR version: Homeowners pay more for electricity than it costs the utilities, therefore residential savings are more expensive than if the utilities installed solar plants, instead.
Which really makes no sense.
What nobody (including me) seemed to question was the premise that our spies knew what they were doing and had some understanding of how the world worked.
The spies in the field knew what they were doing and argued that the evidence that Iraq had wepaons of mass destruction was not credible. But the political appointees and neocons re-wrote the reports to justify "liberating" Iraq. Beware of Bolton, the new appointee who is a proponent of going to war with Iran. He was one of those pushing for war with Iraq in the bush administration.
Target levels are typically 700 ppm above the outdoor air CO2 levels. I'm looking at an old edition of ASHRAE 62.1, so they may have increased some of the requirements somewhat since then, but getting from 1100 ppm indoors (400 ppm outdoors + 700 ppm) to 600 ppm indoors would essentially more than triple the amount of outside air required. For most HVAC systems, that amount of outside air would significantly exceed 100% of the system design supply air. There's no way that would be practical in the heating or cooling seasons.
"Typical"* indoor ventilation is supposed to be designed to hold the indoor CO2 levels below 1,000 ppm, or, in more recent codes, designed to be no more than 700 ppm above the outdoor CO2 concentration.
But the CO2 measurement is just a surrogate for measurement of other indoor pollutants, and really only measures how much outdoor air you're providing compared to how much respiration is going on in the space.
*"Typical" in quotes, because most ventilation systems don't measure CO2 concentration, but are based on certain prescribed airflows, and also because some well-ventilated offices & classrooms will be well below 1,000 ppm and others will be well above.

No, no. I can remember the '70s just fine. It's what I did 15 minutes ago that I have trouble remembering.

Yes, they have, from the very beginning of anti-trust actions.
They just haven't done much of any anti-trust enforcement lately.
Bernie is not even a member of the Democratic Party, he's an Independent.
Contrary to your claims, if you google aircraft tugs, you will find a large number of electric tug models being manufactured and sold.
Yes, planes are typically hooked up to power (and HVAC) at the jet bridge when they dock; running on jet engine power is terribly expensive. (When planes are in the air, the electric power is often generated by turbines that run on bleed air from the jet engine compressors) The electrical hook-up requires specialized converters and wiring, as most planes use 400 Hz power.

More and more of the tugs are electric nowadays. But you have to have the infrastructure at the airport to charge them, too.
Remind me to never go on a road trip with you.

For most HVAC systems, that amount of outside air would significantly exceed 100% of the system design supply air. There's no way that would be practical in the heating or cooling seasons.
Yeah, but it degrades into water and carbon dioxide.
"Typical"* indoor ventilation is supposed to be designed to hold the indoor CO2 levels below 1,000 ppm, or, in more recent codes, designed to be no more than 700 ppm above the outdoor CO2 concentration.
