This one was cool. Could you also extract iron from the bacteria? EDIT: be sure to watch with the captions on, as the videographer explains what he is doing.

  You can. He has some other videos where he actually does extract the iron and ~~makes a knife out of it.~~ makes a forgeable chunk. https://www.youtube.com/watch?v=RZGAYzItazw https://www.youtube.com/watch?v=RZGAYzItazw https://www.youtube.com/watch?v=OPIUMpiV0IY https://www.youtube.com/watch?v=OPIUMpiV0IY https://www.youtube.com/watch?v=pOj4L9yp7Mc https://www.youtube.com/watch?v=pOj4L9yp7Mc

    In the first link, I understood better many things about human history... Still the guy does not sweat in front of a furnace. Obviously irrelevant, but strange!

      As someone who has fought wildfire before, I personally found that sweat does not accumulate in front of a source of heat. You start to feel damp or wet after you walk away from the heat. Perhaps it is the same with a hot furnace.

      I think he's probably sweating, but the sweat evaporates faster than it can bead up. Or maybe he's dehydrated.. I have wondered what the "behind the scenes" of his videos looks like; when he goes out into the woods does he bring modern water bottles and pack a lunch?

        He does have a video about using "cane" to make a water filter: https://www.youtube.com/watch?v=nG-rNHgFxhs https://www.youtube.com/watch?v=nG-rNHgFxhs

The wilderness he films these in is a 15 minute walk from his house: https://www.reddit.com/r/IAmA/comments/dq0zec/im_john_plant_and_i_run_the_primitive_technology/f601gxd/ https://www.reddit.com/r/IAmA/comments/dq0zec/im_john_plant_... so he doesn't really bring anything with him https://www.reddit.com/r/IAmA/comments/dq0zec/im_john_plant_and_i_run_the_primitive_technology/f61auoc/ https://www.reddit.com/r/IAmA/comments/dq0zec/im_john_plant_...

      hot, dry air has a tendency to evaporate water.
