Instead of inverters, there should be a push for DC network.
Virtually all SMPS would be able to to work with DC (right now) and they won't even need active power factor correction either. Washing mashines with brushless DC motors, most ovens would be fine too. When I think almost everything that I have home, save for geothermal pump and three-phase appliances would be ok powered by DC(0). DC has its own issues: galvanic corrosion possibly being one, arcs too (no self-extinguish 50/60 times sec) but it has no issues with inductance, hence lower transport costs.

- m463 6y agoI see DC used in electric cars, general automotive and RVs. I will say 12v is not very useful, except maybe for LED lighting. It has high losses to travel any distance. To power anything of significance requires higher voltage (or enormous cables). I do agree that it would be really good to use DC, but I kind of wonder what the reality of efficient and useful DC would be like.
- xxs 6y ago12v DC is not even useful for LEDs as it requires current limiting resistors - hence power wasted to heat. The proper (efficient) way to drive LEDs is via constant current source. I meant DC as in 230-330V DC for home/office use. I meant generally replace AC (high voltage) lines with DC ones.
