I think the problem is the lack of a standard. In from of me is my laptop charger and a phone charger. One is 19V and the other is 5V. So you would still need loads of transformers for your different bits of kit. Also I think there are issues with resistance in electric wire and overheating and houses buring down and the like... but you'd have to ask a real electrical engineer for that one. I think it will be an interesting one for the future though. Hi Daniel, thanks for the comment. I think the problem is the lack of a standard. In from of me is my laptop charger and a phone charger.

As I look around me I see rectifiers that turn AC back to DC, my laptop my cellphone charger, computers etc. It seems to me that there would be some case to be made for installing a DC circuit in your house. It would be interesting to see would removing the combined inefficiencies of the inverter and rectifiers in the about set up lead to a more cost effective system. For instance I know my laptop powers supply is inefficient because of the amount of heat it generates, you could fry an egg on it! In addition DC lighting and other services are well proven in boats and trucks. Daniel One of the things that strikes me about a household set-ups like the one above is the use of an inverter.
