| Again just to be clear, I believe this channel is legit. Just the

| Yep. He's the OG. I started watching him in something like

|
| His book is extremely detailed and pragmatic as well.

| If you're new to Primitive Technology then it's worth starting
| from the oldest videos and working forward. These aren't just
| random tasks he sets himself. He starts by going into the
| Australian jungle with absolutely nothing except cargo shorts
| (not even shoes) and then proceeds to build himself a series of
| shacks and houses, starting with nothing more than a sharp stone
| and various plants. Then he starts building kilns and firing clay
| he digs out of the river bank (with a stick) making pots, bricks
| and roof tiles. Then he starts making charcoal and building a
| forge, so he can turn the iron bacteria in the creek into actual
| forged iron objects. He's been at it for years initially as a
| hobby and now he earns enough to make it his "job". He doesn't
| attempt to recreate the paths taken by ancient people - he's
| willing to use modern scientific knowledge - but he does appear
| to live by his rule of not taking anything with him and just
| using only the natural resources around him.

| It is also very helpful to enable captions. He does not speak
| in his videos but he adds detailed captioning to describe what
| he is doing.

| Also if you turn on subtitles you'll get a bit more information

| His videos are also blessedly free of unnecessary music and

| whether on TV or YouTube.
|
| They're very relaxing to watch after a long frustrating day at

| There were videos circulating from Ohio of people disturbing

| I don't think you see this bacteria in the Ohio climate.
| gruez wrote:
| Maybe not this specific kind of bacteria, but AFAIK it was

| antibasilisk wrote:
| i've always found iron bacteria fascinating, is it possible to
| cultivate and farm it?
| jjk166 wrote:
| It is, but the bacteria live off iron already in the water,
| increasing the amount of bacteria won't extract more iron.
|
| More generally though, there is an entire field of
| bioleaching[0] which does use bacteria to either mine material
| or more often recover extra minerals from mine waste products.

| tomrod wrote:
| 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.
| rjbwork wrote:
| 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.

| I think he's probably sweating, but the sweat evaporates

| The wilderness he films these in is a 15 minute walk from

| Not sure why this is here - I enjoy primitive tech's videos

|
| But before watching, be sure to enable subtitles for a
| description of what he's doing!

| I think I've been watching these randomly since the beginning

| It's been a long time since I've seen anything from his

| I think the blog is dead:

| The video descriptions and the pinned comment are also

|
| And John Plant, the guy running Primitive Technology, has
| published a book, which I've not read but could be of
| interest to people who like this kind of content and
| would like more of it in the text form.

| So many people learn that there is subtitles through the
