But such a great idea. It would take a ton of people to get on board with this, and lots of planning over many years, but the potential is well worth it, if not just to stop us from lugging transformers around for each of our devices.

1. Develop a universal standard around 12 volt dc for all electronics.
2. Develop a standard wall plug or distribution system for 12 volt DC.
3. Provide a secondary wiring system in all new houses at 12V DC.
4. Revise our current wiring codes to reduce the number of 110V outlets and circuits required.
