Imagine The Walking Dead started in 50 years from now. The way things are going now, picture this scenario:
>A survivor is walking down a lonesome road.
>They arive at a small resort and there’s a car covered in dust and dirt in the parking lot.
>They approach the car and check whether it still has some bio fuel left in the tank.
>Still plenty.
>They look around spotting a decayed body close by.
>They search the body and are lucky to find a ‘keyless’ key belonging to the car.
>There are no door handles and the battery inside the key corroded away.
>They break the glass and open the door from the inside.
>Finally inside, there’s still no way to start the engine without the key.
>They have an idea.
>The digital wrist watch on the body should have the same battery as the key.
>After a bit of tinkering with some tools they get the key working again.
>They press the ignition button.
>The displays light up but the engine remains quiet.
>The displays show error messages:

Wait, you can’t make ethanol from wood? I guess that would make sense, because otherwise you’d see a lot more wood liqueurs, I’ve only ever heard of alcohol made from maple syrup, birch, and pine (but that last one was from a rural Austrian town and they aren’t allowed to sell it elsewhere, so it might be a little more poisonous than the others). This is going to be a rabbit hole.
Edit: you can, but it’s not the traditional way of turning wood into alcohol, and an efficient method has only recently been developed.
