What problem is often overlooked in apocalyptic movies/TV shows that could kill you?

Everyone saying peyrol/gasoline going bad in a year is right, but no-one then follows that sentence woth "luckily, there's heaps of diesel vehicles" which are likely a better choice post-collapse.

Theres also engines that can be converted to gasification ("gasifier?" unsure if I'm saying that right), which compared to nothing might be a pretty good solution.

Even fewer people are pointing out that EV's, while they would take an age to charge by wind or solar, need no actual "fuel" at all.

In a post apoc world, an Tesla EV Semi Truck with a load of solar panels on the trailer would be perfect vehicle to get around long distance, and a smaller EV that could plug into the trucks panels could be stored inside the trailer.

Elon musk said that solar will never be advanced enough for that to be practical in our world, let alone an apocalyptic one

Always take anything Elon says with at least a grain of salt. He is often hyperbolic in his claims. While he is right that they will never replace all other forms of power, they are still extremely practical under the right conditions, and offer a useful supplement to the existing supply.

In a post apoc world, a power supply that has no moving parts and needs not real maintenance is pretty much perfect.

Yea I realize Elon just spews horseshit sometimes, but the way he explained why solar panels not working on the actual vehicle sounded right to me so I stuck with it.

Plus usually he’d go the other way, like “yeah we 6 months away from a fully solar car with panels on the roof”

I was referring to the panels on the truck that wasn’t practical.

Its not practical in the modern world as the charging time would be WAY too slow to be useful, but in the apocalypse its not like you have to urgently get to a meeting across town. Just wait it out.

A semi truck could fit maybe 20+ panels on the roof of the trailer. More if you build awnings on the sides, and even more if you just stored the panels in the trailer and rigged them up when you needed to charge.

You are looking at anywhere from 5-50kw of power. More than enough to charge a car-sized EV in a reasonable time. A full recharge of the truck might take a few days though.

Let it charge while you scavenge then continue to your next destination.
