1. does anyone know the ratio of pollution from all-the-consumer-planes-in-the-world to all-the-cars-in-the-world? (i feel like military planes and tanks should be excluded, or rather included in a separate ratio for comparison.)
2. how does this pollution compare to oil spills (eg, Exxon's Valdez)?
- lief79 17y agoThe ratio is only referring to sulfur. I'm fairly sure the high octane required for jet fuel would prohibit most sulfur emissions. Additionally, the weight sensitivity would be an added incentive to reduce any unused components, such as sulfur.
- billswift 17y agoDoes octane rating even mean anything for jet fuels? Octane rating is related to knock in piston engines, is there a similar problem in jets? Jet fuel is basically kerosene, not gasoline. And even in piston engines, is there any relation between sulphur and knock?
- Andys 17y agoI calculated it out once... it turns out that planes consume a very similar amount of fuel per kilometre of travel to a person driving a car. However, the distances involved in flying around are much greater than most would attempt to drive.
