"Tesla correctly saw AC as the wave of the future"
I see what you did there :3
There's another movie called 'The Current War' which is finally (somewhat) released after having been shelved for years because of Weinstein's bs. Very good film. Westinghouse was a very interesting man. Invented air brakes for trains, built affordable housing for his workers. When he couldn't invent something, he bought somebody else's patent, and made it work. There's lots of history of the company available, but probably not much in the way of info on the range of small appliances they made.
