I don't really hate DC, it has it's place. I do side with Tesla, and see the advantages of AC, especially for long range power transmission. I do think we gave up a lot of efficiency by limiting our selves to 60 HZ. 400 HZ has less inherent losses, is not as dangerous to the nervous system in case of accidental contact and is easier and therefore cheaper to filter into smooth DC supply power. 400 hz transformers can be designed with smaller iron cores, making user devices lighter. DC does have advantages for battery power low current draw digital circuits.
Opps, sorry, I misunderstood the question.
