Re: So What IS ruined after an Apocalypse?

Cloudy weather will also have a major impact on the amount of energy produced, rain will also have an impact even if the sun is shining directly on the cells through the clouds. Extreme circumstances can cut production down to 10-20% of normal during the midday. The lowered production (including that caused by snow) should still be a concern in a cinematic setting. But cold itself does not noticably reduce the energy produced. The amount of sunny hours is the most important factor, and the number of daylight hours available to a location does not change due to an apocalypse. You should be able to find averages for energy production for every season in whatever locations the party visits if you're that interested, but for a rough estimate a daily bell curve (with a peak at solar midday) adjusted for season is good enough for most purposes. As far as the size of an installation goes, a Super Gadgeteered installation could probably provide double or even tripple the power output of a real world modern one. This makes powering a house is quite feasible if there's some sort of power storage system installed. Solar power becomes a lot less attractive without storage, since the cells won't generate power during night time. |

Re: So What IS ruined after an Apocalypse?
Converting isn't that difficult in a carbureted engine. It is complicated mostly because of a) the prevalence of electronics in newer cars which would need to be bypassed or modified, and b) emissions regulations that would require each vehicle and conversion kit combination to be individually tested.

The fun sized individually sealed cans of ethanol free gasoline for weedeaters etc might last significantly longer

It's not something I'd consider an insurmountable task for a Super Gadgeteer, but it is another component that requires maintenance and could be a target for sabotage. |

Re: So What IS ruined after an Apocalypse?
As far as wind power goes, remember that it involves moving parts, which will significantly reduce lifespan, particularly if in use. Note that many of these things also apply to other mechanical devices, such as bicycles:
Anything actually in use will suffer wear and breakdowns. Axles, gears, etc, that are exposed to moisture will tend to corrode and lock up. Liquid lubricants (grease, etc) will congeal and/or sublimate. Graphite and similar solid lubricants might settle but otherwise won't change. Cables and belts made of plastic, rubber, or organic fibers will become brittle and weaken. Metal belts (like bike chains) won't, though they have the problems above. Seals (used to hold liquid in or out) will also become brittle and weaken or fail. Liquids (contained in pipes or tanks) will probably evaporate, leaving residues. If there is an ongoing source of liquid (drains, condensers, etc) becoming clogged is likely. |

Older style canned goods with heavy well sealed lids , properly stored have been said to last much longer, FDA says many many years but they literally don't make them like they used too in many cases. In some setting apocalypse prepper can goods might exist, they'd be ultra sterilized and/or irradiated and in heavy stainless steel cans probably good a century or two. Mormon staples (rice, wheat, honey, salt) stored correctly last a very long time, salt and honey indefinitely Ammo has a lifespan of up to a hundred years, fifty is the top limit for high reliability as people here have noted, it tends to degrade a bit over time. YouTube has quite a few videos on this topic . I'd make bad storage double its effective aging and very careful storage, half it Largely in a serious apocalypse in modernity, most of the population upwards of 90% will have starved to death or died of disease within a very few years anyway. Survivors will be well armed communities of farmers , a few raiders here and there , well prepared survivalists with farming experience also in groups and probably many metahumans , especially any with powers that would be useful in a community for taking what they want or who just don't need anything. This suggest that depending on the cause of the apocalypse there might be a lot of salvage. Decades or centuries worth depending on needs or method of kaboom In GURPS terms , regular skill rolls for scrounging or a specialized skill (mechanic, auto for car parts, armory for guns) should turn up something. It's a matter of time vs danger I guess I think After The End 2 has rules that might help and its "mutants and mayhem" 80's style is pretty fitting for a Supers setting as well. |

Re: So What IS ruined after an Apocalypse?
It's a while since I read it but this book: https://en.wikipedia.org/wiki/The_World_Without_Us went into some detail about how long stuff lasts without us.

Re: So What IS ruined after an Apocalypse?
My experience with Mark VII .303 ammo from 1943 is that it works fine if stored in reasonably temperate and dry conditions (i.e. in a drawer in a non-leaky house), as long as you check each round and discard the ones that have become corroded for whatever reason. Lacquered military issue ammo (not all countries do this) lasts very well as long as the coating isn't damaged, even in less than perfect conditions.
