I personally wouldn't but I could see the appeal. 24 kWh would run my house for 3 days in the middle of January. Paired with solar I can see the appeal for dealing with power outages compared to a whole-house back-up generator ($4,000 for my house)

The tesla power wall is a rip off.
If you only want backup power a generator is better.
If you want to go off grid and live in a manor that resembles normal life you don't want a power wall.

If figure my leaf battery will hold around 20kwh and only cost me a deposit charge or around $1,000 to $2,000.
So far that's the cheapest way I have found to get kwhs.
Lead acid about $200 per useable kwh for a used forklift battery.
When I say useable kwh that really means 2 kwhs because if you regularly use all your batteries kwhs it will be dead in about a year.

$200/ usable kWh is greater than Tesla cost to build Li-ion packs. If you can get a Leaf pack for $2,000 then it's half the cost of Pb. I just don't see the cost/benefit working out for lead if it's regularly used considering the relatively short lifespan and high initial cost.

Electronic devices have gone from unreachable sci-fi marvels to throwaway disposable gadgets within a few decades. Cars aren't there - yet. But they will be.

The idea that you'll take a part of your car out to fix it will be unthinkable at some point in the future. Maybe there will be car-fix lifehack movies on Youtube's future counterpart.

Yes, the consequence of increasing automation is increasing disposability of goods. As the price to produce a given component, module, or entire device decreases, the need for serviceability also decreases.

We're living in an increasingly disposable culture because the initial investment into the product or relationship is so low that little is lost by starting over new.

But while whole cars aren't there yet, the parts that make up a car are.
Tesla integrated the electronics into the battery pack for a reason - that way the integration and reliability could be improved while the overall cost can be brought down. It makes it harder to fix part of it, but as costs come down and reliability goes up that ceases to be an issue.

The PowerWall establishes an upper bound on the market.

Maybe you want line conditioning more than backup power.

If you line in a manor and live to excess you can have two PowerWalls and a genrator

I would rather have generators, UPS and a dedicated off grid power. No power wall.
I could do a lot more with $5,900 than what a power wall gives me.

I wouldn't say that they 'dart out'. The videos I have seen (dashcam) and my limited (thankfully!) personal experience is that they decide where they want to go and then go there at the pace they decided to go. A noisy, well-lit vehicle does not appear to dissuade them much.

They are large animals and can move quickly if they decide to
