I do use crank LED flashlights. One in my bedroom, one in my car. Has been 100% reliable so far, very efficient. Having said that, I don't know how long of life cranking recharge systems have. If I started using them every day, they might wear out pretty fast.
Solar powered flashlight, I think there will be use for it, but not if you are going to stay on the move for reason Evan noted. But if you are staying in one location, I guess you can find a spot where you can leave the flashlight to get a consistent charge. Maybe not the best technology for me(Oregon) or Evan(UK), but Shorty seems to be in California, so....... they have sun there.
Guns are useless because I'll just run out of ammo. Ammo is also a lot of weight to carry and will slow me down so knives are a lot more handy and useful and won't come as a dead-weight.
I do understand where you are coming from, because yes, ammo will eventually run out, they will weigh a lot, eventually, they
might corrode, rust, etc. But two things:
1) How do you plan to hunt with a knife?
I've never hunted, but it seems like there are very limited game you can hunt with a tool with such a short reach. Maybe a snake?
2) Ammo would not be impossible to come by, as some of the common rounds like .22LR, I don't think will every run out in our lifetime, at least not in the United States. I don't buy them, haven't bought them in a long time, and I have over thousand rounds. Most of my buddies who own a .22(guns) have just as many rounds, if not more. My coworker has ten thousand.
Even if you run out of your personal stock, I'm pretty confident something like that will always be available for trade. Same goes for the 12-gauge. Dirt cheap & abundant.
I personally prefer him to Grylls by a massive margin. As imakuni said he's much more understanding of his surroundings in that he reads up on what the locals do, uses really good bush craft and doesn't do reckless things that Grylls does for the cameras.
Couldn't find a video, but here's the gist of one of my favourite methods
I just saw one of the videos, while I couldn't find the one you were referring to either...... He really did remind me of Survivorman(Les Stroud), whom I really enjoyed when he had a survival show. Netflix I think had 3 seasons of Survivorman, but he reportedly had to end the show due to filming taking too much toll on him, as each episode, he was on his own for one week, while filming the show all on his own. God, it's still my favorite survival show. I look forward to Ray Mears on youtube. Netflix doesn't have his show.
