Beginning of electricity
When electricity began to be used in the USA it was direct current rather than the alternating current that is now used.
This was because a person who was regarded as the “one who knows” said DC should be used.
Currently our “one who knows” about electric cars is the Tesla guy.
So will electric cars always be running on batteries or will hydrogen fuel cells become the dominant electricity source for them in the future.
Oh, to be able to live forever. This being mortal has severe disadvantages.
