I recall predecessors to this idea from the 1970s, which probably implies I heard about them from Futurist Magazine and/or the book Small is Beautiful. It has always been suggested that engineers could do something worthwhile by inventing very simple yet useful things that could realistically be made in poor/underresourced countries or villages.

[sublinear]

As other comments have implied, but not explicitly said, they do their own engineering already with what they have.

Since materials can be scarce and inconsistent, much of it is improvised. That in no way diminishes their efforts, results, or knowledge. If anything, that's way more impressive. Lots of engineers in the first world will throw a tantrum if they can't have things exactly their way and probably still make something that doesn't work as well. Entire businesses have shit their pants and gone bankrupt the moment a part is discontinued.

Trying to do better than the people who live there is not only arrogant, but it's own variation of Chesterton's Fence.

EDIT: I can't help myself and have to post an engineerguy video. It's too important of a topic to not drive this point home crystal clear by someone who is far more respected than me.

Over here in the UK I've seen some pretty original bicycle adaptation with electric motors and even a 2 stroke engine added to aid propulsion.

In India there is a word for this kind of thing Jugaad

As someone who has spent some time in sub-saharan Africa, I can tell you that there is lots that can be done if just seeing the possibilities.

Not everyone everywhere are "engineering oriented", and having people with the skills and eye for practical solutions based on available materials, can help tons, and also open up people's imagination for what can be done.

In fact, this goes for northern Europe too, just that more people can manage without home-built solutions and can "buy away the problem" here.

Also, people where immensely thankful e.g. when my quite clever and crafty father managed to repair a water tank tower that'd been broken for months and years, by sourcing some local material, coming up with a repair design, and having local welders create it, etc etc.

[sublinear]

I've never been to sub-saharan Africa, but I did grow up broke enough to be on the receiving end of people with good intentions.

I'm not saying you're necessarily wrong, but the realities of a situation guided by those who more deeply understand it can very quickly prune the possibilities that an engineer sees. Many engineers would just get frustrated and give up. Many leaders would become impatient with those engineers.

I think to get people's heads out of the clouds and produce real results requires a very special kind of engineer. That is most likely going to be someone local, not an outsider. One can definitely help on the education side of things for the locals, but I'm not convinced that's where the real problems are. It's more likely political and economic. Not even the best engineers in the world are going to solve that.

I suspect you've never spent any meaningful amount of time in the local environments, or you wouldn't have made this comment.

As I elaborated on in another comment, it is commonplace to find that people who have little to no education and resources are missing countless opportunities to implement simple improvements to almost everything.

This mindset of "locals know best" is, frankly, toxic. (just think about the locals wherever you live to see how incompetent they are as well)

What is needed is genuine collaboration and communication between people living in whatever situation and others who are fortunate to have more access to information, resources, education on critical thinking etc...

> This mindset of "locals know best" is, frankly, toxic. (just think about the locals wherever you live to see how incompetent they are as well) [...] others who are fortunate to have more access to information, resources, education on critical thinking etc...

This is insane.

[nchmy]

Care to elaborate? (and not cut out the most important context from my comment)

[AnthonyMouse]

The trouble with your premise is that it doesn't just apply to local people, it applies to people in general. Incompetence is all around us. Notice that everyone is a local in the place where they live.

But local people at least have the benefit of knowing their own situations, which puts them ahead of some other rando who doesn't even have that and presumes to know better.

[nchmy]

And hence, AS I SAID, people should collaboratively work together. There's no presumption - despite you recognizing that incompetence is all around us, you'd be amazed at how many completely obvious things are not done, and other things done very poorly

[nchmy]

What do you figure happened, such that people largely haven't done this?

[stdbrouw]

One aspect is perhaps that simple things aren't necessarily cheap. One Laptop per Child struggled to get costs down, whereas a mass market solar panel is not self-serviceable but at their current cost, who cares. Even in the developed world, you get noticeably more bang for your buck if you buy a cheap, basic car than if you buy a cargo bike that could replace it, because of the fierce competition and huge economies of scale for cars. Touch screens are cheaper than seven segment displays. And so on. (Not a snub on the Open Source Low Tech community, their designs look great!)

[nchmy]

Yeah, I agree with this. Though, I think you could make bikes for much cheaper with some ingenuity. Certainly some bike-powered appliances.

Also I think OLPC was a misguided project, as most of these things are. Its out of stem with maslows hierarchy of needs. Folks who are subsistence farmers with drought, smoke filled homes and stomach parasites don't need a laptop and academic education. They need practical and actionable tools and techniques to better meet their basic needs, a state from which they could better pursue academics etc

[JuniperMesos]

There's not actually all that many useful things that can be made in poor, underresourced countries and villages. It's cheaper to buy them from a Chinese factory that is highly specialized at making those useful things in huge quantities and send them via container ship to the place where they're needed. This is as true for random poor people in Africa as it is for me when I buy stuff cheap on AliExpress.

[CurtMonash]

No scale at which it really took off. Village-wide stuff requires a bit of politics, and anyhow there are donors out there for capital equipment and even a bit of organizing help. Factory-level stuff -- well, the product idea isn't the hardest part of a new business, is it? Etc.

[justinmarsan]

It doesn't make anyone money...
