Since being bit by an AC appliance many years ago (before 3 prong grounded) I never trust Ac power. I recently found Thomas Edison didn't like it either! Anyway since so many things are DC now and DC motors are more efficient than AC and appliances can be made for DC, do you think sometime in the future that power companies will use converters from AC to DC off the AC transmission lines and then use that for household power instead of AC? A 48v DC standard or thereabouts could be used, sure current would be a little more but I'd rather get a burned hand than have a few milliamps of AC that cause the heart to go into cardiac arrest! Anybody agree with me that household 120V AC must go!
