What's your contingency plan for the apocalypse? (lemmy.zip)

Say ww3 kicks off and power goes off - how are you keeping your servers up? Solar panels and batteries?

What if there's a biblical flood and you dont have the means to build an arc? All your servers are destroyed beyond repair?

What if you heard the Feds are coming to cart you and your servers away cos they suspect you of bad mouthing Emperor Tromp? (you're on the run or subject to months of torture and yeah, you're never getting your kit back)

What if theres a war and Luxembourg (you know, the enemy) let's of an EMP pulse that kills your servers and all the infrastructure (power, internet...). How do you access all those cherished pics on Immich?

I'm not suggesting any of this will/can happen, its all just for lols, but have you made any contingency plans? Big binders full of printouts, bug-out bags, those flower-type solar things that track the sun, Faraday cages....

Sounds like a nice setup. I'm jealous :D

But shouldn't that only be a 1.3kWh surplus with the fridge drawing 30W*24h=720Wh?

You're right.

Well, still enough juice to pump all the water we need and heat our meals.

We'll just have to limit hot showers to once a fortnight. Needs about 800Wh to heat the hot water tank.

I don't mean to criticise but if you can add anything more (like the other 200w space) I suggest you should. 👍

Yeah, I mean apocalypse scenario is not my main goal. But it's nice to have a contingency plan if shit would hit the fan.

This is my second season with the caravan, I had an apocalypse sailboat before that. I put 2x100W on it for the first season, added another 2x100W this season while going from 160Ah lead-acid to 300Ah Lithium. It's a night and day difference there already.

I'm plugged in most of the time, either for air conditioning or heating - the Mrs wants her comfort. There's a three-way absorption fridge (220V, 12V or gas) that draws like 110W. I can still be unplugged for three nights or so with that running; which makes long distances or overnight ferries possible without ruining food.

And if we want to stay somewhere without shore power we can flip the absorption fridge to gas and be cooking with gas as well. The compressor fridge chest that sips 30W usually sits in under the awning in front anyway.
