Seven-league boots
I’ve been thinking more about the idea of the boots.
The hydrogen/oxygen might be a problem, because the hot cylinder internals might cause them to prematurely ignite.
I’ve been thinking of a diesel engine, which would get its ignition power from compressing the fuel. It can’t ignite from the hot cylinder. The disadvantage of this is that there isn’t any way of controlling the ignition timing. The cylinder might fire when your leg was still coming down, which wouldn’t work very well. It might fire too late and bash the footpad into the pavement and knock you off balance.
An ordinary gasoline engine might still be a possibility. The disadvantage of the petroleum engines is that you have to factor in the fuel injection equipment/carburetor.
I need to find an expert at small, linear engines.
