Improvements in electrode technology.

He said "relatively" unchanged. Electrode technology is the same as it was 300 years ago. It's just more efficient. Just as the combustion engine remains relatively unchanged - it mixes fuel and air together to make an explosion that drives a piston within a linear shaft. - since the Model T days. 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.
