Doesn’t burn, really hard to wear out, you can just dig it out of the ground, easy to shape and repair.
Except it kills people, and it hurts the whole time they’re dying.

It is a fantastically useful material, except for all the mesothelioma.

This one is only really bad because the asbestos companies kept it secret when they found their product killed those exposed to it.

We are in Australia. The company that mined the stuff was found negligent as they kept selling it for decades after they knew it was deadly dangerous

That and lead in paint and gasoline all worked amazingly.
HelixDab2@lemm.ee 4 weeks ago
Lead in gasoline was a stop-gap solution. If I remember correctly , it was added because we didn’t have the technology at the time to refine gas sufficiently to get the octane levels necessary to prevent pre-ignition of fuel (which causes rod knock) at a reasonable cost. Tetraethyl lead effectively increased the octane level/resistance to pre-ignition. As a side benefit, the lead slightly lubricated the valves and valve seats so that they lasted for tens of thousands of miles, instead of needing to be reground every few thousand miles.
It was a stupid stop-gap though, esp. since the dangers of lead were well known by then.
ColeSloth@discuss.tchncs.de 4 weeks ago
You’re mostly correct. It was an additive to raise the octane rating and did lubricate. However, it wasn’t a gas refinement issue that caused the need. An octane boosting additive has been needed ever since, right up to today. Now the octane booster used is ethanol, mostly.
Race cars and many airplanes still use lead. We’re still making people dumber. Just at a lesser scale.

If you want a sad rabbithole, look at the cancer rates around small airports, which are often much closer to where people live.

You can absolutely get high octane ethanol-free gas; there’s a place near me that sells it. I know that a lot of people with motorcycles use it, because inline four cylinder motorcycle engines tend to be high compression, and motorcycle people tend to be almost religious about not using ethanol. (Which is unnecessary; assuming your motorcycle is fuel injected, the only risk with ethanol is storage for several months at a time with a full tank of gas. If you do that, then you’re going to end up with water in your gas, because ethanol is hygroscopic. As long as you keep riding regularly, or empty your tank and run the motor dry before storing it for more than a month, you’ll be fine with ethanol in your gas.) I know of at least once place near-ish to me that sells 110 octane ethanol- and lead-free racing gas. Ethanol-free high octane fuels tend to be about 25-50% more expensive than fuels with ethanol.
Avgas is another story. The odds are pretty good from what I can tell that any prop airplane is going to need gas with tetraethyl lead. To me, that sounds like a good reason to remove them all from service in favor of jets, but I think that jets have a higher stall speed, which can be a problem, esp. in backwoods areas.
(Jet-a and jet-a1 are kerosene derivatives, and don’t have lead.)

You’re getting something done to your engine every few thousand miles?
HelixDab2@lemm.ee 3 weeks ago
You misunderstand. Before tetraethyl lead was removed from gas–in the 70s, I think?–engines were not nearly as good as they are now. My dad was doing really, really well to get 100,000 miles out of a car in the 60s and 70s; you used to see a service station attached to every single gas station, because of how much service cars needed. Now, 200,000 miles is close to the minimum that people would expect with only preventative maintenance. It’s nearly unheard of for people to need to replace valves and regrind valve seat now, except for high compression, high RPM engines (esp. supersport motorcycles). But that was just normal before the mid-70s. My dad has done multiple full teardowns on engines before the 80s, replacing head gaskets, piston rings, valves, and so on. These days that’s almost unheard of.
I think that the most intensive valve maintenance that I’m aware of that’s common right now is cleaning carbon off for some of the direct injection engines. I know that it’s an issue with Volkswagon cars, but most cars don’t do DI. You’d have to check technical service bulletins (TSBs), but most cars are very trouble free compared to what you could expect prior to the 80s.

Seriously, except for the horrific issues with the stuff, it would be an essential material for various applications.
Its resistance to fire, heat transfer, etc would do wonders for insulation and construction.

Makes me wonder if it could be treated in some way to make it not-so-inhalable. Though maybe we have better synthetic alternatives by now.

As I’ve understood it, the problem is primarily for the people having to manufacture products using it, and at rest it’s supposed to be inert.

Don’t forget about when it’s time to un-make it.
Tearing down old building or tiles containing asbestos is also a huge issue.

It’s supposed to be it tends to get brittle and fracture creating airborne shards that you can breath in but your body can’t break down and that continuously damages the cells leading to cancer.
