"If you are on your computer while using a light bulb to light your room thank Tesla. He pioneered AC and the way we deliver electrical power today."

Oh, so Telsa is responsible for that energy wasting device? AC is NOT the best way to deliver electricity, in fact most devices in your home are converted to DC. AC is only a good way to distribute power within a city, but from the power dam to the city, it's all (mostly) HVDC transmission, then converted to AC for inner city delivery. If your home recieved DC from the pole, you'd be able to make better use of DC power generating cells, like solar cells and battery backup to reduce your dependance on the power company. Most ALL household appliances can run on lower volt DC power (they do anyway- AC power is converted to DC). A 12 volt car battery can light your entire house with efficient LED or florecent lights. During the day you could store enough DC power to meet almost all your power requirments.

AC is what the power transmission grid is, not DC. DC can't be run hundreds of miles (the limit in Edison's time was six miles), and AC can.

Some home devices (electronic ones) do indeed convert AC to DC. Motors are almost all AC.
