A lot of things are solvable if you don't care how much they cost

a couple of years ago it was $2m to store the same energy in the same way.
Excluding the car and heating, it's $40k for battery to store enough power to run my house for a week. Including heating at a 3:1 ratio for a heat pump compared with gas on the coldest week of the last year and it's $80k. That's less than 20% of the cost of the house. Throw in $10k of solar (about 35kWp) and even this far north - on the coldest days it tends to be clear skies and that would generate enough to recharge the battery without even touching the grid. The 35kWp wouldn't fit on the roof, but certainly would fit in a nearby field for basically zero cost for the land.

It's also crazy to think about how energy efficient it is to shorten supply chains where possible.

It'd be better to build more insulated and air tight homes (bonus if they're not single family - shared walls save on heating). Then it doesn't require so much energy to heat and cool.
That's about 10 months of power for my home and car (gas heating). A 40' container on my drive or buried in the garden would power the house through the winter. It's crazy when you think how solvable season-shifting domestic power use is.
