The amount of time and energy | he puts into making these is amazing. | neom wrote: | Totally unrelated to this video, just related to the subject | matter on YouTube. Interesting how some of these style videos are | totally bs. | | https://youtu.be/Hvk63LADbFc | | https://youtu.be/_0-uLF9PtNo | | Again just to be clear, I believe this channel is legit. Just the | genre on YouTube has some disingenuous stuff. | pawelduda wrote: | Primitive Technology is the first channel of this kind. These | bullshit channels are just leeching off its success. | rjbwork wrote: | Yep. He's the OG. I started watching him in something like | 2016 or so. | MrFoof wrote: | For a while he didn't produce videos because he was | contracted for some television shows in Australia due to | his meteoric rise in popularity, but he thankfully was able | to return to YouTube last year. I assume his contractual | obligations had been met and no longer was bound by any | exclusivity terms with the broadcast network anymore. | | His book is extremely detailed and pragmatic as well. | masklinn wrote: | Apparently the TV deal fell through: https://www.reddit.c | om/r/PrimitiveTechnology/comments/lfsq04... | | > Another post on February 8, 2021, explained that Plant | shot a pilot episode for the project but the network | wanted to change the format, and that Plant could not | share any more information. | | The /r/primitivetechnology mod had previously reached out | to Plant after worry related to the hiatus: https://www.r | eddit.com/r/PrimitiveTechnology/comments/gscvv8... | jjk166 wrote: | I was under the impression the hiatus was because he | couldn't go to his filming location for an extended | period of time for covid-related reasons. He's certainly | had to start over/rebuild many of his projects. | Quequau wrote: | For those who are hearing, there are subtitles that you should | turn on. | mike_hearn wrote: | 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. | beardog wrote: | 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. | inglor_cz wrote: | I am a huge fan of Primitive Technology. This guy would not | surprise me if he built a PC XT out of mud, slime and wood one | day. | philo23 wrote: | Also if you turn on subtitles you'll get a bit more information | on what he's actually doing and why. | [deleted] | jiggawatts wrote: | His videos are also blessedly free of unnecessary music and | shouted all-caps voice overs like many similar productions, | whether on TV or YouTube. | | They're very relaxing to watch after a long frustrating day at | work. | [deleted] | ramboldio wrote: | could this be used for 3D-printing? | martythemaniak wrote: | I present to you the best Hacker News comment I've ever read (it | was in response to another Primitive Technology video): | https://news.ycombinator.com/item?id=32697419 | nielsbot wrote: | If I get stranded in ancient times, I hope to God kragen is | there with me. | thunderbong wrote: | Man, that entire comment thread is like mind blowing! So many | things were possible but didn't happen. Made me wonder about | the number of things that are possible now but isn't! | tunesmith wrote: | That's extraordinary. If kragen is around, I've always been | curious what, if any, of our technological discovery history | has really been time-gated rather than just dependency-gated. | Like, are there certain technological advancements that simply | would have been impossible before the year X, when Y happened? | calibas wrote: | I believe this is Leptothrix bacteria, it creates an iridescent | sheen on top of stagnant water, often mistaken for oil. It's | quite common once you know what you're looking for. | 2OEH8eoCRo0 wrote: | There were videos circulating from Ohio of people disturbing | water and then seeing this iridescent sheen appear alongside | conspiracy bs. Fascinating! | markdown wrote: | 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 | something similar (ie. biofilm created by bacteria). | 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. | | [0] https://en.wikipedia.org/wiki/Bioleaching | 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. | | https://www.youtube.com/watch?v=RZGAYzItazw | | https://www.youtube.com/watch?v=OPIUMpiV0IY | | https://www.youtube.com/watch?v=pOj4L9yp7Mc | lapama wrote: | 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! | stevehawk wrote: | hot, dry air has a tendency to evaporate water. | sn0wf1re wrote: | 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. | slackdog wrote: | 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? | pcthrowaway wrote: | He does have a video about using "cane" to make a water | filter: https://www.youtube.com/watch?v=nG-rNHgFxhs | kllrnohj wrote: | > when he goes out into the woods does he bring modern | water bottles and pack a lunch? | | 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_... | | so he doesn't really bring anything with him https://www. | reddit.com/r/IAmA/comments/dq0zec/im_john_plant_... | LeifCarrotson wrote: | Not sure why this is here - I enjoy primitive tech's videos | (often imitated, never duplicated - too many imitation channels | have poorly-covered excavator tracks and chainsaw chips when the | work crew and camera crew come in between cuts). | | But before watching, be sure to enable subtitles for a | description of what he's doing! | isbjorn16 wrote: | or, conversely, turn them off before it starts and try to | figure out what he's doing and why. then when it's done, turn | the captions on and watch it again! | | our living room turns into bedlam when we do this. everyone | shouting what is about to happen or why it's happening and | we're almost always wrong. it's great! | pangolinja wrote: | I like going into t mobile stores and changing the loud TV | channels to primitive technology. it's beautiful to see the | whole place calm down. | [deleted] | tomcam wrote: | I wish I had as much energy as you | pangolinja wrote: | I like going into t mobile stores and changing the loud TV | channels to primitive technology. it's beautiful to see the | whole place calm the fuck down. | SV_BubbleTime wrote: | So... Maybe in the way back of my brain I knew there were | subtitles, but there is a good chance I'm _just now_ learning | about this. | | I think I've been watching these randomly since the beginning | just trying to figure out what he's doing. I thought that was | the game here! | skeaker wrote: | It's been a long time since I've seen anything from his | channel, but I recall that he would put out blog posts | explaining the processes shown in the videos too. | tomashubelbauer wrote: | I think the blog is dead: | https://primitivetechnology.wordpress.com | | The video descriptions and the pinned comment are also | really information dense though. | | 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. | ArcticCelt wrote: | So many people learn that there is subtitles through the | comments section after many years of watching all his | videos, probably because the videos are so enjoyable even | without the explanations. | golemiprague wrote: | [dead] ___________________________________________________________________ (page generated 2023-03-03 23:00 UTC)
