'''Basic Concept'''

As it stands right now there is little to no widespread usage of DC loops in a home, most instead rely on inverters from a battery bank or dc power source to an AC wall outlet. Even worse some then plug in inverters to charge their devices batteries. This is a very inefficient system. In order to increase electric efficiency, as well as convenience, we should develop/popularize a standard for DC power at a mains electricity level. This isn't intended as a replacement for AC power, but a complement, and efficiency booster.

'''Current Standards'''

1. "Cigarette Lighter/Barrel" style socket:
-typically 12V
-large and cumbersome

2. "USB type A female gen 1 or 2"
-typically 3 A 5 V 15 W maximum voltage
-much smaller than barrel socket
-becoming more universal, but has many different forms requiring many different cables

3. "USB type C"
-typically 5 A 20 V 100 W maximum volage
-similar size to "USB type A female gen 1 or 2"
-very universal;only one form and cable is identical on both sides.
-can also be thunderbolt 3 which has more power transmission capabilities

4. Power Over Ethernet (POE)
