LOL…. cats are……You’re a good neighbor. 
I like many cats, but some cats are jerks. 
1. Generator: I borrowed a Honda EU22i 2.2 kVA last time there was a power outage for days. This helped keep a fridge running.
2. Power wall: LG have some cheaper cells coming onto the market but it’s still pretty expensive. There are government subsidies to pay almost half the price. This might be appealing if you already have a subsidised solar panel installation.
3. Portable battery backup: I have a 10,000 mAh power bank, a 20,000 mAh power bank, and an XTAR PB2S charger / power bank. The power banks are useful for keeping mobile devices powered. I also have a bunch of 18650 and 21700 cells. The cells can be used in my XTAR PB2S power bank or in laterns and flashlights etc.
Without a generator, I probably wouldn’t be able to work from home. Our laptops would run out of power quickly.
Luckily we use gas for hot water and cooking. Water was contaminated (i.e. overflowed and wasn’t treated) for 90+ suburbs during a storm / power outage. We couldn’t drink the water without first boiling it.
I ordered an BLF LT1 after a recent power outage so that I didn’t need to bounce light off the ceiling with a flashlight while having dinner.
Large amounts of power storage (over 500Wh) is tricky with the solutions we have so far. A Tesla Powerwall would be great but its very expensive.
Hence small amounts of power are doable, LED flashlights/lanterns, a powerbank for phone/tablet charging.
Something in a powerbank that could run a fridge, furnace, computer would be nice if the price were reasonable. And if it could be recharged with solar power.
7kv Kubota diesel genny.
Many power supplies up to 500w.
500 plus flashlights. Over 500 lithium batteries.
And more than 40 lanterns (I collect them both.)
Still nothing is enough when a hurricane hits.
The house can lose the roof, or the house itself
can be thread to pieces. Then no preparation is enough.
Or impossible to reach.
I also have a bigass ax in the bedroom. To go thru
debilitated walls, an out to the total chaos outside.
Cheers.
We have no ethanol “recreation fuel” here, which I use on all small engines. Also, up in many of the boating areas on the great lakes, stations like Mobile, their 90 octane fuel has no ethanol. Usually, if it’s 90 octane, there is no ethanol. If 92 or more octane, it has ethanol.
I’m guessing your water heater uses a thermopile which generates a small voltage (sub 1 volt range) needed to turn the electrically controlled gas valve on and off. The thermopile is heated by the pilot light.
I have about 500Wh stored in multiple powerbanks 
Mmmm, that’s what I figured, as it’s right near where the fire is, down at the bottom.
Nice, simple, self-contained…
