>> And we are stuck on AC which is a terrible and wasteful way to move electricity.
That's a really strange thing to see here on HN. Where did you get this idea?
BTW Europe having 3-phase AC to the home is brilliant. Wish we had that in the U.S.

Why is this strange? I see this kind of ignorant nonsense here all the time.
This site is absolutely full of software people who, because of Dunning-Kruger, think they're experts at everything technical. Electrical engineering isn't that far from the software world (computers are electrical, and their design is within the EE world), so software people frequently think they're experts at anything EE when in fact they don't even understand Kirchoff's Laws, much less the realities of modern-day AC and DC power transmission.
There's been multiple discussions here in recent months with these people advocating absolutely idiotic stuff like a whole-house 5V DC supply, showing they don't even understand Ohm's Law.
On a side note, it's very frequent that I see posts here from people who apparently have never heard of an ad-blocker, yet are complaining about ads.
Theres a reason why china is spinning up DC power grids while posts like mine get bashed on.
Are there three phase sockets available? I'd think you could build things like high power audio amplifiers or power supplies at radically better price points, if this were actually usable from the wall in places.
3 phase is 120 degrees out of phase. Wall power only has a single phase, 360 degrees. Via +/- rectification the situation gets more complex. The key thing, as the other commenter points out, is that there is always always power available. Where-as with wall-power you literally drop to zero voltage as you go + to - & back.
