Less funny when you consider that the Tesla press release submitted here for discussion says, "The Powerwall consists of Tesla’s lithium-ion battery pack, liquid thermal control system and software that receives dispatch commands from a solar inverter." The inverter, of course, converts battery DC current to household AC current so that people can continue to enjoy AC power in their homes. http://electronics.howstuffworks.com/gadgets/automotive/dc-ac-power-inverter.htm http://electronics.howstuffworks.com/gadgets/automotive/dc-a...

That raises a question: if one were to build a new house with solar and battery integration present from the start, would it make sense to run DC appliances?

Well obviously. Everything runs off AC, no one would buy this battery pack if it didn't have an inverter.

  That didn't look at all obvious when I replied above, because I was replying to a comment that said, in so many words, "Funny that something called Tesla Energy brings back direct current to the home." No, Tesla Energy is not bringing back direct current to the home. It is providing battery backup for continuing provision of alternating current to the home, which is strictly necessary in a world of appliances that run on AC current. I took the trouble to read the fine article before replying the first time, after first reading the previously posted comments. (My late dad was an industrial engineer for a company that manufactured electric generators, so this issue immediately jumped into my mind when I saw the comment I replied to. The difference between AC power and DC power was dinner-table conversation in my home when I was growing up.) Does anyone think that my comment above was in any way harmful to the community or to the discussion here?
