I like the idea behind this. I feel like far too often, the solutions we build for poor communities involve specific materials that can't be manufactured locally, so it just creates more dependence rather than self-sufficiency. It's one thing to build and ship 1000 bicycles to a poor village, but it's another to teach a village how to make bicycles with random spare pipes and materials they can find anywhere. That wa…

I strongly agree that it's incomparably more important to teach a man/village how to fish/build a bike than to give them one. Unfortunately most people who focus on "helping" are grossly incompetent and have largely misaligned incentives (and oversight). As for local innovation, it think it very much depends on where. I've visited and lived in many communities in developing nations in Latin America and there's a dist…

When I went to South Africa last, we went through a few slums.

It was comical to see the celebrity "assistance" in the form of e.g., a music production studio + school set up by skrillex, neighboring areas where people lived in shipping crates with stolen electricity jumpered directly from main, and with water tapped off city lines and bucketted in.

They dont need djs, they need plubmbers, carpenters, and electricians first! Fires and water loss were endemic. Almost everyone lived off government assistance, stole / smuggled resources, and blocked traffic/protested when the illegal resource taps were shut down or a government job didn't manifest. The people who made money where they lived usually washed cars or sold trinkets to tourists or brewed bucket beer.

I think, largely, both options should be used in tandem. Give the hungry some fish, they need it, but while you're there teach them how to fish

I've been following this guy a couple of years now (as well as many other mentioned in the comments like LowTechMagazine, Simplifier, OSE, etc)

I always liked the WiFi catenaric (instead of parabollic) reflector for it's simplicity,though I think drawing parabolas shouldn't be that difficult either to get a more directional reflector

it's very easy to verge into OLPC type thinking with this, you probably should just give them normal bikes instead of trying to come up with some bespoke DIY-able system

the OLPC was the "send them bikes" disguised as the DIY-able system. They designed what they thought would be the best computer for impoverished children when in reality those children had no real use for a computer

My wife came across the Jean Pain compost water heater recently, and I've been really intrigued by the idea. I haven't found a great compact design though, and most of the information I see online treats it more like a fun project than something that could be iterated on and refined. Would love to find somewhere to trade ideas on this and potentially replace some or all of gas water heater. Here's a decent post about…

You might want to look at biogas digester design - I met farmers near Hanover who were running big biogas digesters, and using the excess heat to heat their homes and pools all winter…

Oh thanks! This is exactly what I was thinking!

Sort of in the same vein, I've really enjoyed this book: https://www.goodreads.com/en/book/show/76998.Reader_s_Digest... Lots of really interesting tidbits, and a great lemonade recipe, among lots of other gems.

For a more academic approach see the Foxfire Series:

> I strongly agree that it's incomparably more important to teach a man/village how to fish/build a bike than to give them one. Unfortunately most people who focus on "helping" are grossly incompetent and have largely misaligned incentives (and oversight). It goes deeper than that if you ask me. It's rarely about "helping" in a lot of cases in the first place, and there's no incompetence at play either. Just look at…

The White Man's Burden by William Easterly covered this in some detail quite a few years ago.
