Diesel vs. gas isn't "apples to oranges", it's "apples to typewriters".
While there are issues in a comparison of Diesel and gasoline fueled motors the similarities are so much closer than 'applies to typewriters' that your statement leaves me shaking my head and doubting everything else you've said.
Both convert fossil fuel to motion.
Both use fuel/air mixtures under pressure to create combustion.
Both use pistons and crankshafts.
And I could go on and on.
Apples grow on trees and provide a good source of food energy.
Typewriters are mechanical devices used to put symbols on paper.
They both have beneficial uses but further comparisons are few and far between when compared to comparisons of Diesel and gasoline.
