All I'm saying is, it's not a matter of fuel efficiency, it's a simple matter of weight ratios. A one ton missile cannot be manufactured and deployed without a comparably sized carbon footprint.
I have not done this but: literally search the post word for word. Weird to just throw out "I don't think this is real" like we're in the woods in 1945 and a plane accidentally dropped a ream of newspapers saying the Nazis surrendered.
