“We were able to show through our hair samples what the lead concentrations are before and after the establishment of regulations by the EPA,” said demographer #link(“https://profiles.faculty.utah.edu/u0030780”)[Ken Smith];, a distinguished professor emeritus of family and consumer studies. “We have hair samples spanning about 100 years. And back when the regulations were absent, the lead levels were about 100 times higher than they are after the regulations.”
Note for everyone that it’s not in fuel for turbine engines, it’s in fuel for piston engines (though progress is being made).
bullshit.
They could have mandated E85 two decades ago. they just kick the ball forward with studies and consultations. E85 is 108 octane rated.
Ferrocene might be a better drop-in replacement, since it wouldn’t affect the fuel’s vapor pressure.
Still though, I agree this should have been handled decades ago.
What are you calling bullshit on? Doesn’t look like your comment correlates with the above one
So pretty much personal aircraft only not commercial.
Some small piston engine aircraft serve remote communities in places like Alaska, as well as things like research stations and some remote infrastructure.
Although its mostly personal aircraft, yeah.
