On a third hand, electricity is just movement of electrons. While DC is driving electrons down the line, AC is basically just when you vibrate them around. Anyway my point is the field (no pun intended) may change drastically in the increasingly electrified future. I'm personally excited for more wireless power in areas, and the concept of ambient energy - harvesting power out of the already vibrating electrons in the static in the air. |

Think of DC more like you're trying to pump a frozen ice mixture drink (trying to avoid any of the major brand names) down a straw. If you melt it, that's loss to heat. If the pressure gets there that's DC current.
The AC vibrations are the same thing except it's like the lever action on a steam locomotive. Translating the motor's spin into a back and forth wave in the line.
This is why AC is rather useful for making other things spin or vibrate to the point of being emissive.
