The technology is the same, but today's engines have learned to maximize, relative to the early 1900's, the efficiency of that technology. The change in technology would be the Wankel rotary engine, which as near as I can tell, works on witchcraft. (I keed. )


A radical change in electrode technology would be to change the basic way in which that technology works - - i.e. something other than a positive / negative electrode doing the work.
