No where in the original article or any of the links is the number 12kW mentioned. At Slashdot, don't assume the article synopsis has anything to do with the actual content. I would assume most modern houses could handle an additional dedicated 220V/20A circuit for the slow charge, but don't underestimate the hassle of plugging in the car every night. Ooops, forgot to plug-in last night, now I can't make it to work this morning.
