>> Edison clung to direct current long after the advantages of Tesla’s alternating current was known.
As if to suggest he was an idiot for doing so.
Whatever, Donovan. The art of discovery is inevitably a factor of dogged ignorance.
Hail the wisdom of the beneficiaries... /s
Edison was half quirkiness, half tech genius. Doggedness helped him formulate the best light bulb filament possible with the technology of the time. Only when tungsten became feasible was it beat. But he was fighting the laws of physics with his visions of a DC power distribution system. AC yielded the option of being able to distribute the same power with less loss, and being able to stabilize end user voltages whether near or far. Since Tesla also had quirky, quixotic visions that had nothing to do with what we know as the engineering advantages of AC — like transmission of power for free through the air — this could have complicated Edison’s perceptions.
