This is the website of CD3WD which is a compilation of DIY info for 3rd world countries on EVERYTHING useful: agriculture, animal husbandry, food processing, water purification and sanitation, how to make different kinds of stoves, how to recycle various materials (not just how to put them in a bin, but really how to recycle them yourself), small scale mining, pottery making, dyeing, brick and tile making, construction, health and diseases, refugee healthcare, "family planning", vaccines (!), education, business, economic development, economics, metal working, woodworking, electrical, electronics, computers, auto mechanics, biogas, soapmaking, all kinds of homesteading and permaculture stuff, etc. etc. You can either browse their website, download 34 Gigs of info, or pay them $24 for DVD's of the info. They will also send the DVD's free to any third world country address for the shipping cost.
It goes without saying that this is really useful info for anyone wanting to get off the grid, raise their own food, or after the crash when we're all standing around saying to ourselves, how do we do all this stuff now that our infrastructure's gone to hell and we can't get it at Wal-Mart anymore?
