Pretty impressive how much power these things can produce!
If you don't want to watch 19 episodes spanning a few years, he put up three summary videos of the project starting at episode 20: https://www.youtube.com/watch?v=61lZn1sUkzE
I can't even...
It's fairly popular in a wide range of applications, mostly either machines with too much current or too large areas to reasonably measure temperature or parts that are too small (vape coils for example can be used in a temperature coefficient mode).

Though the really impressive part is the shirtless picture of Gabriel. Dude is shredded from what I assume is solely from manual labor. If true, incredibly impressive.
There is also a book in German called "Leben auf dem Lande" (How to live in the countryside) describing how to do all sorts of things in agriculture. It cured me of any desire to live on a farm and really makes me hope badly that there won't be some sort of incident that makes me have to become a farmer or do other basic things, like building my own power plant.
Edit: of course I am also impressed by the people who built this thing in the article. It is just that it makes me realize I would be unlikely to be able to copy their feat.

I miss this. I actually miss the joy of the page downloading. I miss the unqiueness of the websites and the content. What we have now for a global internet is great and the tech and the content is beyond amazing but, we have also lost something too.
It's actually refreshing to see someone doing their own thing, like, truly their own thing.
That said, the dude could use some CSS-skills.
Although I can totally imagine the reaction of someone like that to modern web frameworks. He might be inspired to roll-his-own... he did with EDA CAD as the creator of KISSCAD.
No way you'd be able to just DIY it either - some of the permits will require licensed contractors.
- decreasing the amount of water available downstream.
- changing were the downstream water ends up.
- changing the speed of water downstream.
- changing the variability in the stream’s deficit the downstream.
- making it harder/impossible for animals to move along the stream.
I would think this does do the last, and, likely, also the next to last.
It might modify where the wetter parts of the area are, but I don't think that equates to destroying it.
Additionally, there are some definite issues with sedimentation during construction. They excavated the channel to the intake and put all the dirt from the excavation into the stream for it to "carry away". This would not be allowed in most areas I know of - essentially, fish can't breathe if there's too much dirt in the water. Then several times it overflowed and eroded the channel - more sedimentation. The author even admitted using concrete liner would be the better choice, but opted not to because it was expensive - essentially, this externalized the cost of sedimentation to the ecosystem.
Nature minus humans endlessly causes the same sort of change, but to second an earlier comment this would be a nightmare to try to do in a lot of areas. In my area the most dire thing to touch is the flow of water -- with three layers of government/protection agencies monitoring it with a very close eye.
It's not primarily an ethical thing. We're just trying to prevent this place from burning itself to the ground. That requires everyone to have a certain discipline with their angrier impulses here.
(Your comment would be just fine without the last sentence.)
The only disappointing thing about his projects was the house he built. You go out to live in paradise... and decide to make your home in a cave SMH.

fyi: I'm also Chilean.

quite an inspiration!
Is it an impulse turbine (which I believe is the most efficient?)
Besides the legality of it, in Northern Ontario, the land I had there had a fair sized creek running through it but over the 400 meters that the creek intersected the property the height difference was only about a meter and a half. You'd have to do major engineering to make usable power from that, the cost of the tubing and the turbine might be just low enough that it would compare favorably with a windmill.
It definitely is a great way to make power though, as long as the creek does not freeze (and as long as your precious tubing and Pelton wheel don't freeze) they'll make continuous power and that is really neat.
> Another restriction is that there is no power at this place. Bringing power here would require a 350 meter long transmission line through dense forest, or else installing a solar panel, battery and regulator. Due to the low head available between the intake dam and the forebay, a picohydro system to provide some power is hardly feasible. Solar power is quite restricted too, because the place is in a deep valley and gets only about 3 hours of sun a day. Furthermore, in winter there is often no sunny day for a full month! So panels would have to be dimensioned to run on diffuse light from the clouds, and that needs big panels to produce only a little bit of power.
On a direct-sun day, they generate 4 kilowatts, but under heavy cloud I'm lucky to get 500w
I would expect a lot of red tape, but depending on local jurisdiction that might be very doable in Europe if you're willing to buy the right place for it.
On the other hand, older mills are often covered by the protection of historical monuments and can therefore not be altered as you like. This should really be looked into before buying anything as it will be an absolute showstopper with no way around it.
And if you try to do what the guy here did you'll most likely run into water way authorities with requirements for fish ladders and so on.
It's doable but it's not as easy as laying some pipe through your garden.
And the communes take the state of their waters very seriously as well.
You'd likely also upset various environmental groups due to a lot of protected species living around.
From a UK perspective theres quite a lot of paperwork. You have to get surveys for flow rate over the year, and theres limits to how much you can divert.
Both those combine to mean that it isn't really worth it unless you're off grid, and in the right location, with enough land, and water.
So solar wasn't an option here though likely would have been cheaper and definitely easier.
