A capacitor has ~1% of the storage capacity of a battery of similar power rating.
Saying its storage performance is better because its holds a larger % of that capacity at low temperatures is nonsense because its storage performance objectively sucks (and not what it’s designed to be good at)
It’s like saying a Tesla is better than a 747 because it can go from 0-60 faster. A technically true statement but a meaningless performance comparison.
30-50% of my energy is the EV. About 20% is 120V plug loads (computers, fridges, home server), ~5-10% lighting, ~15% large equipment (dryer, electric range, electric water heater), and the remainder (15-30% seasonally) is HVAC (heat pump)
Any gas appliances would bring a lot of those numbers down
American House with an EV, all electric, and no solar, I use about 1200 kWh/mo (1.2 MWh/mo) on average. This could only carry me through about 3y. Even if I had access to good public infrastructure I think best I could do is 6y (again, all-electric home).
But I digress. Lithium ion as purely load shifting is a pretty reasonable, I’d argue critical, solution for covering day/night loads, but starts to fall apart completely when it comes to seasonal (summer/winter) loads.
But what makes this plant interesting is the addition of super capacitors. The combo battery/SC plant is less about day/night load shifting and more about providing stability to a shifting grid. As supply and demand grow increasingly decoupled, and we try and shift away from expensive peaker plants always on standby, systems like this can dramatically help smooth grid performance.
~90 MW of peaker capacity is small potatoes currently, but this is a big step towards a more reliable grid future.
Supercapacitors provide ultrafast response times – specified at 0.001 seconds – and maintain over 85% capacity at –40°C, significantly outperforming lithium-ion batteries in extreme cold.
Outperform how? At being a capacitor? That’s their whole point.
On the energy side, 85% of 29 MW-min is 0.41 MWh. Even if the batteries lose 99% of their capacity at -40 °F, last I checked .42 MWh > 0.41 MWh.
These are two different tools for two different purposes, I’m not sure how you compare their “performance” under this metric.
I’ll run a backup and restore when moving to a new device, because why not. But regular backups? Meh, the ether can have my messages if my phone dies.
That said, depending on how this new system is rolled out, I may subscribe just to support the Signal foundation.
(I get that corporate environments are often off the table for this).

We created a totally secure and definitely unguessable (Probably Unique)™ identifier system - an MD5 hash of FirstnameLastname-DOB
Oh also with this new totally flawless system, you’re now legally obligated to recite I’m full your (Probably Unique)™ 32-character hash to any ICE agents who request it. Failure to do so will result in detainment.
For immigrants, we will happily tattoo your (Probably Unique)™ hash on your wrist for your convenience.
Did you try getting rid of the old one and putting the new one in its former place?
My understanding is many of the ones that are only rated for water have additional nooks and crannies where the liquid you are carbonating can get trapped, yielding nastiness over time.
I think there’s a lot more to it than cost. Men, even with considerable health care resources, are often very averse to mental health care.
Thinking of my father in law, for example, I don’t know how much you would have to pay him to get him into a therapist’s office, but I’m certain he wouldn’t go for free.
This is genuinely inspiring to me, may be my new ADHD hobby for the next couple of weeks.

But if one person buys a book, trains an “AI model” to recite it, then distributes that model we good?
Great, you stole my domain. Now I have to come up with a whole new brand for my new line of travel sized fleshlights.

Certainly sounds familiar, my tip to him is to try and write recipes down and get in the habit of mise en place-ing (prep chopping / pre-measuring) when you know what you’re gonna cook. Once the food hits the hot pan, any semblance of a plan goes out the window
(but also know “sticking to habits” is hard for us with ADHD, as it frequently goes against our nature, so don’t be shocked if he struggles there)
I tend to be the one to cook the “whatever’s leftover in the fridge” dish, which is a guaranteed source of a little chaos. In those instances it’s always helpful to have my wife around to pass ingredients or do some prep tasks on the side so I don’t lose focus and burn the onions.
Also, if you don’t already have recipes written down, having someone help build out a recipe book as you go can help smooth out future cooks.
Shout out to Recipe Keeper - after a first cook, usually from a website or book, we put everything we like in there for future reference.
