Trying to regulate 5V across 14Ga wiring isn't anything anyone would do. If 48V became some sort of DC standard then devices would work off 48V. That might not make sense of course and how much sense it might make could depend on line voltage (120V vs 240V).
There is a cultural thing here too. If you live in a place where all heating is done with combustion then there is no particular reason so not do everything with low voltage DC. Now that lighting is LED based there wouldn't be anything that would need the higher voltage and power.
- simcop2387 11y agoNo it's absolutely not what someone would do, but it is what the grandparent proposed, that's why I addressed it. I'd love to see it used for more efficient lighting, as if it was done correctly I think you could get some pretty nicely efficient and long lasting lights that way with a bigger better current driver for the leds. This might be a good idea to move Track lighting to since they'll have more freedom on the sockets and interfaces. As far as other devices needing the AC power, you've got hair dryers, kettles, vacuum cleaners, air conditioners, water pumps, etc that all need more power than would be reasonable with low voltage DC (some might need 25-50 amps to run at the same power they currently use). All of that just means you'll still have the AC running through the house for a very long time anyway, so you'll end up with nothing changing.
