Just saw this video that uses a car alternator and a small 220 watt engine to produce power. Would this actually work?

No!
It slows down eventually (because of friction) but it's a nice experiment.
Perpetum mobile does not exist.

I imagined this when I was 13, then learned physics.
Plus, it violates the 2nd law of thermodynamics, so it's unlawful

Ah. I get it - the little engine is one of those that used to be used to power pushbike lights, yes?

Its possible to convert wood or straw in to gas for running a petrol generator. Similar to how gas was made from coal in hot air baloons before compressed lpg.

Another thing to keep in mind...

If you do pressure cooking, then you can eat the product cold, so there's no need for cooking after storage. You can just eat from the jar. (Though, there are a few batches I have which are a couple of years old now, and I'd want to cook again after opening just to be on the safe side.)

I read over on the ol' canning thread that you'd ideally want to boil your pressure canned meat for 10 minutes to kill any suspected botulism. Of course, this safety tip only applies if your future reality includes the option to cook your food!
