Whole-home PoE for lighting might be another interesting approach!
In either case, you'd need a very beefy DC power supply somewhere to get enough current, or individual power supplies scattered inside walls, etc. which sounds like a maintenance nightmare.
- nippoo 4y agoOr keep the voltage high and step down with a buck converter in each socket as needed and negotiated with the device: there's a good argument to use ~300VDC as a future home electrics design. High-power devices (water heaters etc) will work better and more efficiently with DC, and low-power devices can deal with 48VDC with a lightweight step-down converter (5A buck converters are tiny)
- CapstanRoller 4y agoFrom a purely technical standpoint, I agree completely. However, given the debacle around USB-C cables & PD, I'd be very worried about a world where I have to trust devices to properly handle such high voltages.
