This too is incorrect. If a vehicle is made with for street purposes, it can never have its emission devices removed. Even if it used as a dedicated race car
As you probably know, I was referring to custom built race cars, such as Indy or Nascar. But yes there is a very tiny set of cars that were once street cars that have been modified and now only race and never, ever, even for a minute, drive on the roads.
Maybe in terms of CO2, but turbines also don't burn as completely as most piston engine cars. 10k is probably an exaggeration , but the pollution is much worse than the fuel economy indicates.
Similarly, my chain saw probably pollutes nearly as much as my new Honda truck even though it only gets a few gallons of gas per year.
But nobody drives their Ford F-250 10,000 miles a week. It's not about the energy efficiency of someone's mode of transport, it's about the total emissions from their transit habits. You know, the actually important metric when measuring an individual's impact on the climate.
A Gulfstream G700 carries 22,407kg of fuel (about 6,100 gallons at 800kg/m^3 ) and a max range of 14,353km (8,918.5mi), for 1.45mpg. Closer to 10x, by a bit. Using the 12,316km high-speed cruise range manages to bring it down to 1.24mpg, just under 10x worse.
Yes but an F250 does not use leaded gas like many planes do, has much more complete and efficient combustion, and likely produces far less particulate emissions.
Just curious, where in the wikipedia article does it say Private jets don't use leaded gas ?
Just searching the article for "lead" only gets this quote: "The possibility of environmental legislation banning the use of leaded avgas (fuel in spark-ignited internal combustion engine, which usually contains tetraethyllead (TEL), a toxic substance added to prevent engine knocking), and the lack of a replacement fuel with similar performance, has left aircraft designers and pilot's organizations searching for alternative engines for use in small aircraft."
Also a reference to "Planemakers challenged to find unleaded fuel option - The Wichita Eagle" a 2009 article which has a dead link.
Curious to me why you would cite an article that says the opposite of your assertion and then repeat the definitive statement. I must be missing something.
Jets don't use avgas (which is still available with lead), they use jet fuel.
The planes you are thinking of are mostly used for hobby flying or some short haul commercial flights, e.g. float planes. These have piston engines, more like your car ICE.
It's funny watching you all use different words and think they mean the same thing. Turbine powered aircraft, whether jet, fan or prop (a Citation is a turbofan powered aircraft) use Jet-A which is basically diesel (OK, OK, it's kerosene but they aren't that different). Piston planes (of which there are plenty) mostly use 100LL - high octane, leaded gasoline. Now that we're done with the pedantry, please continue with your argument.
And furthermore, it matters where non-CO2 pollution is released. Particulates released from a jet at cruising altitude, particularly over an ocean, are less harmful to human health than a truck belching pollution next to a kindergarten.\
I'd also add that two wrongs don't make a right, and while not strict enough there are emissions regulations for aviation.
I think you're probably rather exaggerating the difference here, but nonetheless, sure, let's regulate or the tax the shit out of private jets too, I'm okay with that.
