I don't think you understand the significance of that.
MurgatroidMendelbaum - 2016-07-31 Technology develops at an exponential rate.
This time next year, he'll have developed multi-core integrated electronics powered by refined fossil fuels.
Lord_Crocodilicus - 2016-07-31 He claims to have invented that spin blower, which is cool. I've seen how the Africans do this, and it requires basically an entire village to make one iron hoe using 2 goat skin forge blowers.
I'll go ahead and submit that video.
glasseye - 2016-07-31 Yeah, double bellows are a lot less work and provide more consistent flow if you can build a big enough set.
Tough American Bouncer - 2016-07-31 But building bellows is much harder. You would need a good skins and good leather crafting skills. I could not build a bellows with valves using primitive means, but I could probably build this blower.
Oscar Wildcat - 2016-07-31 It is too small by about an order of magnitude to be of much use for iron. That's the problem. Otherwise, very clever!
SolRo - 2016-08-01 It would work way better with 10 curved blades and some vibration sensitive LEDs.
Simillion - 2016-07-31 i love this stuff. I used to mess around with iron and homemade backyard forges during high school. I appreciate this guy's work
