Thanks. I always wondered if that was what that meant. 35 mph is really good gas mileage. Gas trucks don’t get that

Oh yeah. Sounds like you’d be a good candidate for it.
My wife charges for free at work, so we kinda considered it too (charge at work, and backfeed to the house when she gets home). It’s a bummer they’re so damn expensive.
One thing you’ll wanna keep in mind is that if you’re only producing an extra 2kw and you’re charging at 7kw (L2), you’re gonna be pulling 5kw from the power company. So you’ll probably want a charger that you can limit to 2~3kw…. We do that by only using the 1.5kw charger that came with the car and plug it in to the 110v outlet.

Actually thinking about it, it might not be a moral panic thing. It could be that if people use midjourney for pornography, that will play a roll in its training that could screw up the searches for others. Its like using google search with safe search turned off; even a perfectly innocent search can still result in NSFW results. So they exclude the porn searching while the AI learns so that it doesn't pick up bad habits while its in the early stages of its training
Also the company might also not want their AI to get associated with porn. That's just not good for PR

Pop in salt cooled latest Gen nuclear reactors and that footprint goes way down.

What about using photosynthesis to create a ton of biomass stored energy in the form of plants that can be used as kindling to warm up the house at night?

of course it's converted to AC.. you need to do that to use it in your house anyway.
Well DC is only used for HVDC lines as far as I know, at least day to day for most people.
people without batteries rely on net metering. They use to solar panels during the day to either reduce the amount of power they get from the power company or they even produce a surplus during the day and send some back up the line for local distribution. This reduces their power bill but they still rely power company for power since for safety reason they have the aforementioned power cut off so line workers aren't zapped. So no you generally can't use your panels if you are grid connected with no batteries though in theory you would just manually disconnect from the grid and power the house during the day depending on how much you generate and how much you need.
For those with a battery but are connected to the grid it's a bit different. They of course use the panels to power their house but also charge up batteries for later use and once the batteries are full send power back to the grid. They of course use the batteries at night or during inclement weathers when there isn't much sun. If the power from the grid goes out they can instantly switch to solar, battery or a combinations of the two depending on the circumstances.

1st Gen ioniq EV. It’s been an amazing little car.

Well, you by your electricity in United of kilowatt-hours (KWh). 1000w for 1hr is a KWh. In order to compare it to gas costs, you need is miles/kWh. (I’m assuming you’re in the US where you don’t calculate gas as Liters/100km).
The simplest thing you can do is take the range of the car, and divide by the size of the battery… (the EPA range you see here in the US is a good place to start)
So. We have a 1st Gen ioniq, which has a 38.5KWh battery, and it gets 170 miles per charge. So the math goes:
170 / 38.5 = 4.4 miles/kWh. (Which is really good)
(In reality, commuting at lower speeds we usually average 190miles/charge.)
Anyways, now that you have your miles/kWh, you go to your power bill and look at how much you’re paying per kWh. And how much gas costs.
So in our case we pay about $0.28/kWh and gas is $5.00/gallon.
So then you do ($gas) / ($kWh):
$5.00 / $0.28 = 17.8 you can buy 17.8kwh for the same as a gallon)
Next you multiply the kWh you can buy with the miles/kWh.
17.8 x 4.4 = 79 mpg based on epa mileage. And local electricity and gas costs.

Good points. 4 things come into play here. 1) we have a solar roof that overproduces, since we’ve made other energy cuts. So I’ve got a little “free electricity” to use. 2) we’re about 60. As described by the 06 vintage of our current vehicles, we run them into the ground. So our time is now, not next Gen. 3) my wife REALLY REALLY doesn’t want a small vehicle. 4) With the kids out of the house we’d like to go to 1 vehicle. We’ve passed the age where the minivan is the perfect vehicle. Since we still enjoy our yard work, the pickup becomes the perfect vehicle. In truth we rarely push the reported 300 mile range. So yeah.. when they were first reported at 40-60k I wanted to take the risk. Last year the model I liked was 70k. So we’re putting it off, for now.

This is much better than a centralized solution. From a defensive point of view, if you keep all your energy infrastructure in one place it makes the whole country vulnerable to an attack. However if you used this roof top idea it would be fully decentralized making each unit area independent of others, isolating attacks

Probably not even all rooftops. Just focusing on the large flat commercial rooftops would be huge, and lower installation/maintenance costs

What about old chemistry....did we abandon it for this new generation hip chemistry.
On a serious note, progress is awesome

LFP struggles with range and cold weather performance. The energy density of the chemistry is very poor compared to high nickel based chemistries, and leads to very heavy and expensive packs to meet range targets (more cells to hit the same energy).
It's primary advantages are in it's comparatively better thermal propagation performance and in cost - although the need for additional cells to meet range and the piss-poor recycling economics (LFP costs more to recycle than it's individual components are worth) eat into this financial advantage.

But in this specific case, if they knew masks would be in short supply they could have recommended cloth coverings as a placebo that wouldn’t actually be harmful. The government is demonstrably not infallible.

If you read the article, you'd see that the new chemistry is LFP - Lithium Iron Phosphate - which has been around forever and is still a lithium ion based chemistry.
