How did the Brits make buses run on coal?

Heck, we Yanks have aircraft running on coal.

Since you mention that, does the water injection they use on planes like the 52’s have any application in internal combustion engines? I've seen homemade rigs used water or alcohol to prevent knock at either high compression ratios or under forced induction, but can you get any more power out of a piston stroke by adding water vapor?
