basically it seems that DC eats significant power loss over long distances unless it's in the megavolt range. it's potentially more efficient to transmit extremely high voltages in DC rather than AC, but then you run into two problems:
1. existing infrastructure is not designed for that so you'd have to convert back to AC for local grids and
2. it is both expensive and inefficient to convert HVDC back to AC, or if we were to switch to a purely DC grid it'd also be both expensive and inefficient to step it down to usable voltages unless you ran 750kv directly to homes
doesn't really seem practical with current tech
The article I copy/pasta-ed that from mentioned electric trains/trams used to be on 750vdc but they changed it to 25,000vdc (with the train stepping it down with a transformer) as it was much more efficient that way. -

That’s not how electric distribution works
Electricity isn’t “returned” to them you dumbass. It’s already been generated at the plant, what you’re paying for is the load that you draw from the system.
What the fuck are you even babbling about? -

Well in some instances it's fed back to the grid.
"On a grid-tied system, homeowners with rooftop solar panels generate the electricity they need, feed the surplus to the grid, and only turn to the grid when their systems aren't generating enough to meet their needs."
My dad gets a check ever quarter for like 30 quid for the electricity his solar system feeds into the grid. -

2023-10-13 at 8:26 PM UTCYou are metered for your electricity before it even gets to your device. Electricity always returns to the source of the power supply (a transformer or substation).

Yeah that’s people with generation on their property like solar, and if you do that gets metered going the other direction so you get reimbursed via a bill credit.
I’m just talking about your random Joe Schmo’s house. The power company generates a certain wattage and increases or decreases it depending on the peak load requirements of their service area.
But it’s not them sending power to your house thru your meter, then taking it back and using the same “piece” of power and sending it thru your meter again. Like it doesn’t even make sense what he’s talking about lol I can’t even wrap my brain around what he thought he was trying to say. -

You are metered by the load draw on the system. If you have a 1000 watt device and run it for an hour, you get metered for 1 kWh.. what are you not getting? -

You were wrong...
We know the device is bullshit but "TECKNIALLALALALALY" the grid IS capable of accepting 'returned' electricity. -

The point was you’re not being metered for it over and over again which was spectral’s point, who we all know is fucking brain dead and has no idea what he’s talking about. Not sure why you’re somehow defending his position when you ALSO know absolutely nothing about it. You’re middle management at a factory. Go back to jacking off on work hours Homer… -
2023-10-13 at 9:24 PM UTCYou’re only being metered for what your devices draw and what’s lost to waste heat, that’s it. Spectral says otherwise and I disagree

I mean, people with solar panels can - with certain providers - sell energy back to the grid. This is a thing that happens, I'm pretty sure. Without a solar bank you could still, depending on the provider, offset some of your bill by banking charge during low demand hours of the day and selling it back during peak demand (assuming your energy pricing is rated by demand @ a given time of day, but I suspect the margins on this would be slim-to-nonexistent and you'd probably be better off just using the power you banked during low demand yourself). 🤔 -
2023-10-13 at 9:33 PM UTCA set-up like that would presumably require a pre-existing agreement with your power company and a lot more infra than a shitty little thing you plug into the wall though. Talkin' more... like... a massive battery bank. Like, an electric car's worth of batteries type dealie, plugged into your 240v utility outlets.
I think Technology Connections on Youtube had a video about this actually. -

Yes I understand all that… me and spectral are having a totally separate conversation. He seems to think you’re being charged for electricity thru your meter that you are not using, which is not the case.
I’m not talking about bill credits and selling power back to the grid and shit like that, that’s a totally separate conversation.The following users say it would be alright if the author of this post didn't die in a fire! -

Sorry, my bad, I noticed after I poasted.
But yeah idk what spectral is sayin' - a capacitor'll just de-noise your electricity, clean up the "signal" you don't care about. I'm assuming this is actually a vital part of how LAN over powerline tech works, but it's not useful for saving energy. -
