Was close to being carbon neutral by then I had a stroke vnow my wife has decided she’s happier than with a propane boiler in lieu of a wood gassifier which is a boiler it used about half the amount of wood than my old boiler did.
Imagine being the person responsible for making an entire generation dumber on average. That’s a sad legacy to leave behind.
Dont worry, the Flat Earth Society doesnt have to imagin
@Actually, Movies yea. because you were born after the clean air!
The freon problem was difficult to anticipate (if not impossible), but lead was an obvious problem. Hard to believe a less poisonous anti-knock agent has not been discovered.
Orrrrr, go electric. Geez!
@Fuseteam ꧂ Here in US. ethanol is cheaper than gas. Isn’t that the same every where?
I noticed the super unleaded gas and stuff is more expensive than regular “unleaded” gasoline.
We use his other discovery – ethanol in fuel. If you go to a gas station, you’ll frequently notice it mentions the fuel mixture contains at least 10% ethanol. To assist with the costs, this is also part of the reason why the agricultural industry will receive many government subsidies, especially for corn to be turned into ethanol for the express purpose of being added to fuel.
The irony of him poisoning himself, poisoning others, then dying from his own contraption. This guy was the grim reaper.
But he was stupid 🤑 Rich! 💀
He was definitely cursed.
Yeah. He just didnt get the memo.
@Old Man Doing High Kicks Only In Black Socks no the people who butchered his ideas and implemented a shitty version deserve it
Karl Marx has him beat easily.
Already saw this story few years ago but I still can’t believe how insane this is…
It’s seriously wild how many stories there are about people like this selling the human race out for a couple bucks
I remember being 5 years old and filling our old Commodore with leaded petrol while other children also did the same. This really makes me wonder how much damage all of us received during these times. I also wonder if lead poisoning could be the reason some smelter towns here in Australia have high violence(especially domestic violence) rates as they currently blame work/life balance and alcoholism. Usually more predominant is copper towns.
@The Berserk Horse There is no reason to bring race into this lol
You have to remember that it was a prison conley for awhile and the some of people don’t have the best gene pool in the past.
Australians are way more aggressive than the average person worldwide period (except the southern states of USA). It’s like almost everyone in Australia is a “cracker”. I’m from Canada and when I visited Australia it was insane to me the difference in temperament even in the more civilized places in Australia. Why do you think this is? I could not imagine growing up in Australia, everyone is so in your face.
No I don’t think every death they caused was accidental… negligent at best.
Incredible story by the way, thank you for another amazing video.
@Lunatic 0verlord you mean midgely
@Captain Chair stop apologizing for Mao.
My thoughts to.
Cosmos: Possible Worlds (2020)
I gonna watch the whole season now 🙂
Dude… you just blew my mind with the lead exposure graph. The fact that you can correlate the Greek and Roman empires? That’s so freaking cool!
“Accidentally” seems like a generous way to title this guy’s story.
It’s interesting that the person who caused the harm in this case did so much of it and did it with a huge amount of support. Meanwhile, the person who tried to undo it had to go to great lengths to prove there was a problem and was still seen as extreme at the time.
