It depends. When I was around there, they had some trouble with solar panels. Talking to them, they had no clue at all about electricity (just like many first-world dwellers I guess - and probably not enough money to get somebody who has to come fix things). If a techie teamed up with them, they could make so much stuff, like powering a generator with a water wheel in the river - easier to understand, and all the problematic parts are what they are good at.
