One of the buzzwords doing the rounds in the past few years is ‘personal fabrication’. The idea that in the foreseeable future we all will be able to fabricate our own stuff. And although the founder of the fablab phenomenon, MIT professor Neil Gershenfeld, is pretty nuanced about it (watch his TED talk on the subject), some are actually talking about upsetting the traditional supply chains for manufactured goods. It actually is one of the stated goals of the Global Village Construction Set project by Open Source Ecology. The heavily ajective-laden newspeak of their website, this is actually a cool project. Watch Marcin Jakubowski’s TED talk about it. Also read Far McKon’s rather thoughtful criticism of it on his blog. The snark in me prevents me from omitting that the Open Source Ecology are doing everything in imperial measurements. Which aren’t quite useful for your stated target audience: farmers and villagers in the developing world. Get with the program guys, use metric!
Other than that, I find any ideas on reducing our interdependencies a bit interesting. There are a few snags here and there. First of all, economies of scale matter. They matter a great deal. Actually, a lot of the activity in hackerspaces would be impossible weren’t it for the fact that China has become our global workshop. There is no way other than massive robot usage in which we can ever dream to meet the current price-performance ratio of the Chinese manufacturing base. Also, do not forget that current shipping all over the globe is probably one of the last things to survive through the permanent oil crisis we have just entered. Simply because the energy expended lugging that container full of stepper motors for your repraps from Shanghai to Rotterdam or San Diego is actually pretty low. A shame that those massive container behemoths burn really dirty oil for that. Not even the next leg, either inland shipping over the river Rhine or over rail from San Diego elsewhere in the USA (granted, electrifying US rail networks would be a big win and will be inevitable). It is the last hundred or so kilometers that are the really energy-intensive part of those steppers’ journey.
Personal fabrication only makes sense for niche products such as spare parts and when access to the world’s supply chains is not really affordable. Which indeed means the developing world, but perhaps also rural communities in a not so distant future in which the world has stopped shrinking and has expanded again because oil is not so cheap anymore.
All of this does not mean that the GVCS is not an incredibly interesting idea that doesn’t deserve support. It also doesn’t mean distract one jota from the fact that affordable CNC-machines and additive manufacturing will make craftmanship accessible again, without the five years minimum you have to spend to get a skillset need for say, advanced woodworking. In the past lots of us had great ideas that would require the collaboration of several disciplines and therefore execution would be difficult. Now that lasercutters,CNC-mills and 3D-printers are within reach of hobbyists and hackerspaces, these barriers are crumbling. Atoms may or may not become bits, but lasercutters are cool!
