Comment by Alex2037 6 days ago that depends. transferring 1 MW at 1 MV produces very little heat 3 comments Alex2037 Reply nine_k 6 days ago 1 megavolt means huuuge spark gaps, I'd say no less than 20", given dry air. This also means very thick insulation, very bulky and expensive switches and breakers, etc.Tesla 3MW charger uses 1250V DC: https://en.wikipedia.org/wiki/Megawatt_Charging_SystemLiquid-cooled charging cables are a thing. too; one of many: https://www.mouser.com/new/phoenix-contact/phoenix-contact-5... Thorondor 6 days ago Yes, but a car can't use electricity at 1 MV and converting the megawatt back to something lower than 1 MV still produces a lot of heat. loeg 6 days ago Vehicle battery packs are 400-800V today; not 1MV.
