    The same goes for fuel for a generator and/or car. It’ll last one person’s lifetime easily.

    Cars would, definitely. But would fuel? Petrol generally has a shelf life of around 6 months. If stored in an airtight container you can store it for a year. Then it starts to deteriorate. Like those 20 year old cars in “the last of us” definitely wouldn’t have worked with the gas they just had sitting around in the tanks. 5 years well stored still functional gas, but according to my searches 10 years wouldn’t.

    But it honestly wouldn’t be too hard to make fuel. I don’t know about petrol but some engines can run on used frier oil and making very pure ethanol isn’t much of a challenge.

      Yeah, I don’t know. Is that shelf life when it becomes non-functional, or when it starts destroying your engine? The latter wouldn’t be an issue. There’d be effectively unlimited engines/generators around. Who cares if they start breaking when using bad gas?

        Well it does both. It actually degrades even when not exposed to air. Loses combustibility. That worse gas then can damage an engine yeah. Damaging engines wouldn’t be an issue, that I agree with. But the gas will just go bad in 10 years unless you make more. I get judged for this a lot but I use Gemini on my phone and while LLM’s are still largely garbage, it’s kinda good for weird hypotheticals you probably wouldn’t find on the first page of Google.

        I told it I was writing a book so it doesn’t complain about putting old petrol into a car. I asked whether tank truck which would fit 5m3 (5000l) of petrol would still be good in five years when kept from out of the weather and at a steady 15C. Said yeah, it would very likely be usable. Then I asked 10 years. Said no. Then I changed it to be a massive tanker in similar optimal conditions. Said that it probably wouldn’t be usable.

        But you know, I don’t take them at their value, but I have always known it has a shelf life of some sorts. The complexity of the chemistry related is just a bit out of my comfort zone.
