It is always good to have backup plans, even if they aren't practical now, they might do in a pinch. (Or in extreme environments). It is amazing that food and fuel are as cheap as they are right now. All sorts of things can go wrong on a global scale, it has happened more than once before. The best way to have a backup is one that has already been tested, even if its on a small scale.

Thanks for posting this. I'm done with having my examples picked apart, so I'm not going to do it with him. The fact is that it's less crazy than it used to be, which is a good trend.

I subscribe to many channels like this on youtube, and sometimes interesting things show up years later. I expect at some point I'll need to weld 2 incompatible things together, but by then the folks at "Impulse Manufacturing Laboratory at Ohio State" will have figured out how to do it, for example.
