I do too. If I remember correctly hearing that his experiment was trying to balance and send out 110v across the wires only a few miles.

But if he produced high voltage and ran his wires over 100 miles he might have shown how the losses are indeed less than ac in the same setup. Our cable technology is very different from back then too

Dc can be transmitted any distance but is only more efficient over ac in the very long distance range (with appropriate infrastructure = $$$). Our current grid uses ac as there are less losses to do so (arguably in certain areas) due to the smaller length of transmission.
