can we make a new thing? ie, i love what weve been able to do with USB-c as far as standardization... could we make a higher voltage, single plug 'thing'?
Relevant XKCD.
What I'd rather see is a standardization of PD installed in houses. That is, as part of the electrical installation a high capacity PD power supply is installed, and USB C sockets available on all power sockets. It would be more efficient to do a one-off central supply.
The problem is, that PD supports many voltages, so there'd need to be some way to dynamically generate those.
But, a good DC house supply would be a good thing and easier to provide some kind of battery backup for.
i started swapping out outlets with a dual usb-c model. quite bulky, and from the sounds of it not very efficient
My uninformed take on this is that its almost impossible because countries have different power standards. Of course i may be entirely wrong, or correct but with an entirely incorrect reasoning. Please people who actually know correct me below
We could make low voltage DC wiring a thing inside homes.
PoE works really well, data and power over a single ethernet cable for various low voltage devices. I have PoE powering network switches, WiFi access points, doorbells, cameras and raspberry pis.
The main problems is high amperage required to get the same wattage and the difficulty to change voltage with dc; coming from someone that has a small workshop running out of 12v dc from solar panels and batteries
It depends on what you're running, but I used to work for a low voltage lighting company. We did mostly 24vdc.
We could but the amount of time that would take would be ludicrous, and that's if you can convince people to switch. People don't like change.
Hell, the switch to USB-C isn't even fully complete. Sure, Apple finally did it after the EU twisted their arm, but some companies still release products with micro USB. Idk if it's cheaper or what, but it's definitely annoying.
i think the micro to usb-c is about supply chain. current production needs to run out the supply of the cheaper micro pieces. at some point it will be cheaper to use usb-c than micro and we wont look back.
