I see the problem now: you're an asshole with no life experience and no functional knowledge.
Powerwalls are an expensive luxury compared to PV solar panels, which do go as long as the sun is shining.
Solar doesn't work during a power outage:

You're a fucking idiot who has no idea how residential rooftop solar works.
And why leave home? Is it cooler outside?
Go to a hotel with working AC so my newborn baby and son with asthma don't die. Because vulnerable people die in extreme heat: https://www.cnn.com/2023/07/10...
You're a fucking idiot who has no idea how the human body works.
You can afford Powerwalls (two!) but not insulation??
Two Powerwalls installed is about $17,000. The cost to fully renovate a 35 year old home to achieve anywhere near 1 or 2 ACH50, including replacing all existing insulation, air sealing and ventilation system install, replacement of all windows and doors with modern energy efficient ones, duct sealing, foundation insulation, etc. is between $70,000 and $90,000. And even doing all that won't help the loads of thermal bridges present in the original construction, so you'll still see massive heat exchange when you're looking at a 30+ degree gradient. Yeah, I looked into it.
You're a fucking idiot who has no idea how home construction works.
Survive? OK, now you are getting ridiculous. You know AC is a recent invention, right?
You know hundreds of thousands die each year due to heat related causes even today? Including plenty in the US in places that are used to seeing high temperatures like Arizona: https://www.azfamily.com/2023/...
Particularly when you look at vulnerable populations like the elderly, newborns, and people with respiratory issues like asthma.
You're a fucking idiot who has no idea that people die every single day due to heat and have for as long as humans have been a species.
Mammals have survive for tens of millions of years without freezers.
Groceries are expensive, which you would know if mommy and daddy didn't buy all yours.
Boobs produce milk on demand, last I checked.
No they don't, ya fuckin' retard. That's not how they work. Again, no life experience.
Milk supply can drop suddenly: https://onewillow.com/blog/wha...
It can even stop with little or no warning due to stress and lack of sleep: https://utswmed.org/medblog/de...
Further, if a mother is working and exhausts the available time off, but still wants her baby consuming what every bit of scientific research on planet Earth has said is best, she needs to have a stockpile of breastmilk available.
So, again, you're a fucking idiot who has no real experience, no real knowledge, no real concept for how humans, houses, or technology work. Do the human race a favor and go win yourself a Darwin award before you infect the gene pool.
