Meh. Not what it looks like to me.

240 in the neighborhood - i.e., that’s enough to distribute from the pole to a few houses. Of course you have higher voltages to go longer distances. This is equally true for AC vs DC. Thus, the idea that it takes a looot of copper for DC is erroneous.
In fact, where conductor size is relevant is that you can use smaller conductors for DC, because of the skin effect.
Wiring: Split phase, that is also usable as 240 for large appliances. So, the latter.
There’s a HACS integration called ‘variable’ that might help. Create the variable, then just:
This game is absolutely fucking solid.
Negatives:
Yeah. Basically, the biggest reasons for AC have to do with voltage stepping up and down, and for instant grid load knowledge. Well, and of course, existing infrastructure.
Both have solutions, but aren’t as cheap as they are for AC. But, aside from that, DC has a lot of benefits, particularly in end usage efficiency and transmission over distance.
Back in the day, the capability to easily bump up or down the voltage of electricity just wasn’t there for DC, so AC was the distance winner (high voltage is needed for distance, low voltage typically needed for usage).
I mean, you need a lot of voltage to make voltage drop irrelevant. Like, 120 or 240 volts. If distribution is voltage is the same dc/ac, we could use the same wiring (but different breakers, and everything else).
So the wiring argument doesn’t really hold up - the question is more about efficient converters to reduce voltage once it’s at the house.
I.e., for typical American distribution, it’s 240 in the neighborhood and drops to 120 in the house. If the dc does the same, the same amount of power can be drawn along existing wires.
Best description.
If it helps, it’s supposed to be a drop-in replacement.
Yep. And decommissioning time? The sodium is all recyclable without major effort, and the Prussian Blue analogs can be discarded.
Lower price and longer life.
50,000 complete cycles. That’s 136 years of complete empty to complete full. Most of these will outlast their mounting hardware.
Meh. Lemmy’s ephemeral, and there’s no way Google can tell that a link on lemmya.ml and on lemmyb.xxx are actually the same Lemmy post.
tbh, this is a lemmy issue.
Not only that, they’re terrible on the toxicity front.
No. He leans back, and blazes music like a bonfire into the night sky.
Trees are technically a green, renewable fuel (if humanity used them that way). The carbon dioxide released is that which was sequestered during the tree’s life.
But oil is gathering material that accrued over vast amounts of time, and using that, dumping huge volumes of co2 directly onto the air. There’s no cycle happening there - just pure extraction for our extinction.
May as well give up then.
I mean, not so very long-term (like, now) there’s also sodium-ion prussian blue batteries. That’s some damned good tech right there, and it’s at the beginning of its development arc - there’s a lot of room for improvement, and it’s already good.
You say “do something” and follow or with “protest”?
Beep beep coming though!
