Accidentally?
Shame on Veritasium - that isn't even clickbait - it's plain wrong!
Thomas Midgley knew what he was doing - and didn't care about the human consequences.
By some strange fate, Midgley contracted polio in 1940 and, because he was so clever, he invented a complicated pulley system to help him stand up - it duly strangled him in 1944.
Try to understand how many decades it took for the legal authorities to make such genius products illegal. And they are not illegal because you or I could knock them up in our garage, and hence do untold damage to our neighbours; no, the laws were to stop corporate scum from poisoning the whole planet. They have other products now.
As it turns out, ironically, the polio vaccine may be responsible for killing millions more. Dr. Bernice Eddy discovered a carcinogen, SV-40 (Simian Virus-40) in the vaccine. Of course the other researchers, driven by the profit motive, called her "a hysterical woman" and now the Boomer generation has one of the highest cancer rates in history.

Boy do we keep falling for the same BS over and over again. If it benefits industry, it's probably not good for us.
yep, abhuman alert.
but they were never sent to an asylum for therapy, instead they got rich poisoning life with their brain-damaged ideas.
🤬!🆔
Reminded me of this A-whole

I just watched this yesterday. Leaded fuel for all! No wonder we get dumber generation after generation.
But also notice that toxins are only removed when (a) the evidence is staggeringly obvious, and (b) there is some other toxin to replace it. eg unleaded petrol is far from "healthy", indeed, the recent concerns about graphene oxide often forget that such molecules are also formed from exhaust fumes.
I actually had time to watch this video. I learned a lot from it.
I remember my HVAC instructor who also was part owner of his contracting business he gave to his son was ecstatic one day as he found another contractor going our of business and bought a lot of canisters of R-22 refrigerant. He got a steal on them because the lack of manufacturing was daily decreasing what one could use. They were pretty much limited to whatever was being salvaged out of units being replaced.
I mention this because as we see time and again, it isn't so much always about cleaning the environment, you still can as long as you can pay the right folks, lol.
Also amazing how many people refer to refrigerant as Freon when that is a brand name.
Even more troublesome is I was never able to get work in the HVAC field. They somehow failed to mention no one hires a man quickly on his way to being old when there are so many young bucks coming out with the same degree who can put in the years of grunt work in installation before going to the gravy side of repair. Yet I was able to pass that test and am one of the few who have a universal EPA refrigerant license despite never once having worked on any system. But to the EPA even if you need a chiller worked on, I'm your man, hahahaha.
I'll ask for your help next time! lol. New aircon unit - with funky almost-new R32 - crashes with P3 error code. lmao. Very unlikely that outside is colder than inside. Anyway, found this gem:
WTF. If that's how they think it works, I shan't be buying anything from Perfect Aire!
Yeah, the title and cartoon made me think it was gonna be shite, but I did actually watch it - just not much point restating everything the video says. lol.
All 19th C tech into the 21st C.
Mind you, most of my students (most people, I suspect) think the copper tubing brings in the cool air!! I should really write some Phantasy Physics posts.
I can get that although it makes me laugh. I mentioned in my other comment I had to train myself to think of it in terms of an ac unit is extracting the heat which results at the end with the cooler air. I can understand how one could think that however, as before my schooling it would have been dismissed by myself in casual conversation if someone would have insinuated such a thing.
I saw an interesting post the other day. It was talking about how they have dumbed everything down. It made a comparison with old car owners manuals and new ones. The claim was that the older ones told you things like how to set your points. The new ones tell you not to drink the antifreezed, lol.
In a very simplistic way that isn't inaccurate really. They didn't mention the evaporator or condenser, nor how pressure is manipulated to change the saturation points to achieve this. But as with many things, descriptions have been dumbed down for the masses.
To simplify it for myself I grew to think of it as it throws the hot air from inside outside and is returning the air minus the heat it extracted in the evaporator. Then it sends it to the compressor to change the pressure to heat it up by changing that saturation point. Then to the coil to allow that heat to be thrown outside. Then to a valve to decrease the pressure so it can once again change its state to allow for the now cooler coolant to be returned to inside.
The compressor does in fact change it from liquid to gas, and then is returned to liquid inside the coil to be sent back.
Still a simplistic explanation I offer as well, but has been many years since my schooling and I've forgotten much of the sub par training they gave me with only having 9 weeks of actual internship at the end with an actual company that does the work.
On a side note, when I say subpar I mean subpar. The way they arrange the classes in order is almost criminal. The first class I had to take was for my EPA refrigerant license. So I passed for universal by sheer memorization, without ever once having seen the parts I was naming nor how they were connected. I was totally ignorant (still feel I am as one begins really learning once in the field). All that class/test demonstrated was my ability to memorize information.
But I felt all the classes were lacking. Even the shop parts of the class. Somehow however I was able to pull off a 4.0 in the core classes of my program, despite feeling very unsettled with the knowledge for any practical usage on my part that I was told I was acing.
I don't even want to get started on the stupid sheet metal class for making locks. Yet when I came out of the program that was probably about the only aspect I felt I could potentially do without much oversight.
Overall I think that gas is bad to begin with and burning lead is just stupid.
Not much I could add except Ethanol to Gas to make it cleaner... or go straight ethanol.
I had some HVAC expertise back in the day before having to leave due to health...
The product I helped inovate went on to become https://bluon.com/
stranger days ahead!
ah, I thought it was gonna be some bromomethane toxic liquid - it's an app!
a plethora of jokes - I shan't...
There is some bromomethane toxic liquid behind the app ... Called Bluon ... Can't remember how we made it... Hit my head and left that life far behind... Their App came later... After the success and sales of an r22 replacement 😎🥓
