Comment on USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray!
ShadowRam@kbin.social 9 months ago_ I don’t think USB C PD could handle a hairdryer though_
Of course it wouldn't. The idea would be get rid of USB-C and PD completely.
You'd have 110VDC@15A available for your hairdryer. Heating coils don't care if it's AC or DC, and the blower fan would be a brushless fan.
You're compressors for AC or fridge would be freq drives, which are cheaper because they could drop the rectifier circuit, and highly efficient.
The only real concern about having DC in the home as standard is the safety aspect of DC doesn't let go if you get shocked.
But that is already being worked on in general as many homes have high-voltage DC circuits from solar panels.

But different devices need different voltages. Does every outlet in my house have to have its own connection to the central rectifier? It’s a lot of re wiring.

PWM DC to DC dropping voltage to what you need is easy/cheep.
So instead of a big transformer + rectifier that each device has now, it would be a much smaller/cheaper step down

This doesn’t seem better.

Well, I mean if you don't understand electronics I don't see how you can make that statement.
