again, simpler and cheaper electronics for everything

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 at like 99.8% efficiency
Yeah, but frequency drives/inverters were still pretty pricy things back then to for high powered motors for compressors/blowers/etc.
But the cost and efficiency of those things have dropped SIGNIFICANTLY in the past decade..
_ 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.
No, it's got nothing to do with power over ethernet.
It's simply having only one high power rectifier at the breaker box.
And removing all those rectifiers from every device in the house.
We don't need AC in the home anymore. Every device is now using DC, and any other device will still work with DC.
The only thing really left are motors, but even those are going brushless and we can chop half of the inverter out of the equation of those as well.
And every device won't even need smart electronics for PD either.
It would also solve the North America 60Hz and EU 50Hz issue, where the AC coming in doesn't matter. We all standardize on a DC output.
And when people want to add alternative power (Solar/Wind/etc), it's a HELL of a lot easier to just push the DC into the existing system without having to worry about frequency matching.
This is exactly why I op'd for Kbin over just Lemmy.
Lemmy + Mastodon support.
I don't get, even if you are part of .world and they are federated with threads.
Can't you just personally block all threads?
You personally can defederate without it affecting anyone else.
Because Boomers don't even know what CS is?
powerful DC-DC
No, are you not aware how these work?
A step down DC-DC is nothing compared to a transformer rectifier or PD electronics with communication with a USB-C.
