It’s a direct quote. But you mean well.
Well damn I'm sorry now I'm curious - a direct quote from what?

I believe liability is an issue too. In aviation (as compared with autos) the manufacturer is often found partially liable for an accident, so they can be on the hook even if it was mostly the fault of the operator.
It's worse now, people are doing "51% Build Assists" (most famously Vans and Sling aircraft) to save money where the factory would give you an IKEA plane kit and you will maybe put in a few screws and decals and install the avionics panel and you will sit in the room and watch them assemble the rest of the plane "under your supervision". Then the whole thing will get penciled whipped as an Experimental Owner-Built ai…
And yet, because these experimental owner-built aircraft are free from many of the burdensome certification requirements, they're also free to use newer and better tech at a lower cost.
Who is safer? The person who "self-built" (but actually allowed the trained factory folks to build) a Kitfox with a full glass cockpit, modern engine, and dual FADEC, or the person who buys a 1972 Cessna Skyhawk with steam gauges?

Then you don't know anything about the man. He intentionally inhaled large quantities of leaded gas to prove it was safe to on lockers. He would then spend months in Florida recovering from lead poisoning. He knew, and he didn't care.
Yeah, that kinda reinforces it. He knew about the acute effects, but not about cumulative damage. I don't think that cumulative toxicity started entering the public mindset until well into the middle of the century.
He's not 'the public' but a highly educated and experienced leading expert in the subject. You have no idea what he knew (afaict) and even if the chronic problems were indeed unknown to him, anyone, even a member of 'the public', could infer that the acute problems certainly risked long-term problems

LPG had the same problem as electric cars. In the early years there was no infrastructure and so if you buy one you're an early adopter and you can't actually go anywhere. It took a while to get that infrastructure and now electric cars are useful for most trips. You can use LPG cars to go for most trips in the US even today. However, you better plan ahead because finding a place of fuel is going to require some effo…
LPG was really popular in Holland, that wasn't the problem. You could get it everywhere. It was cheap too. There were just some artificial issues: - The government didn't want LPG owners to be cheaper off (it was much cheaper per kilometer) so they raised road tax substantially making it only economical if you drove a lot - There were no cars running on LPG off factory. You always had to deal with an aftermarket inst…
Engine performance is actually increased on LPG if you do it properly. It's less energy dense, so you use more of it, but you get a bigger slower bang, giving you more torque. You need the timing a bit different.
The tanks are far safer than the leaky plastic yoghurt pots that people carry petrol around in under their cars. They can't explode, they can't be ripped open, they can't even be dented. I have attempted to knock a hole in one with a 16-tonne excavator and only succeeded in squashing it a little bit. I've taken LPG tanks out of burnt-out taxis that were still half-full.
They're not even under any pressure, they're at 8 bar or so. The main danger if the gas gets out is that it's really really cold!
It's still a fossil fuel causing CO2 release but it's a fossil fuel that would just be burnt in a flare stack if you didn't burn it in a car. No-one is going to stop making propane, as long as we make plastics and fertilisers.

#14525 years ago in the UK, leaded petrol was being phased out but still pretty common. The UK Government was giving people grants to have existing cars converted to run on LPG, so they'd only run on a coke can of petrol for a minute or so on startup then switch over to gas. Catalytic converters? Don't need 'em! There's no CO or unburnt fuel in the exhaust to catalyse because they run as lean as a vegan's dog! CO2 emissi…
LPG and CNG had a consistent niche, but they weren't transformative and ended up not being significantly cheaper either. And recently we saw the problem with natural gas supply availability. With EVs, all of this goes away and you can charge at home, including off your own solar panels. The technology has finally got to a tipping point, thanks to a couple of decades of phone batteries. > you didn't get the Scrappage…
Even down south here at 56°N I'd need a set of solar panels about 100m x 100m to charge even a very small car in less than a day.

:) Baron. some 300hp effective little turbines with non-ridiculous fuel burn would be a "shut up and take my money" moment for me.
I would prefer a twin high wing with the existing TP-R90s. Unfortunately manufacturers don't like dual high wings :/
That Eggenfellner dude on zuckbook has been spamming a continuous stream of his dream twin highwing and it looks nice. I hate his spam but love his mockups, I want it to be more than a paper airplane so badly. :)
