Sorry your reply with question somehow missed my radar until now.
I still say we are on the cusp, because we have run out of usable energy. Now we have to take it from the source Tesla was proposing, the sun. Because the source of energy is in the form of Joules per second, then money representing it has to be tokens per second, which is different from money representing any kind of capital (stored) energy, like that in fuel, or in any kind of kinetic energy already deposited on Earth (Just Joules), and it is received for free, then it follows we must issue free money, in order to realise the value of that freely received energy, which means mathematically that capitalism is finished, since no-one will need capital, with infinite free money. You can check out my recent "Money-fuel Tree" story if you wish more information.
Do you have a link or reference to the source of information indicating the issue you mention, of Tesla maybe not understanding the nature of energy fields?
