That looks like way more than $50 worth of parts.
Nice. Has anyone successfully moved off grid with these micro domestoc generator type setups? Maybe not a single unit, but a series of water, wind, solar etc…?
I can’t speak for the one in the video–although that inventor is a Scottish guy who seems to work in impoverished areas in Africa, Panema, Tibet, etc. so I presume his design works as he keeps using it–but Kris Harbour (https://www.youtube.com/@KrisHarbour) is a homesteading guy in the UK who is running his homestead on a combo of solar, water generation, and wind power.
Kris Harbour’s latest video is him installing a waterwheel for a client, although he himself uses a little water turbine on his own property. He has videos of both up.
That’s the thing. I’m thinking of small omnidirectio al wind turbines, drain flow turbines (like the one in the article) or waterwheels for rivers or drain flow, maybe a small solar installation… would love to give it a shot it if it’s viable for a modern suburban household.

I would say of all of that, solar is probably the easiest to do for a suburban household. For hydro you’d need land with access to a stream or something, and for wind you might run into local ordinances about noise or the height of the structure or the like, in a suburban area at least.
Speaking of ordinances, given that solar has taken off so much, depending on where you live I have heard you might have to obey local laws about installation of that too?
I am in NO WAY an expert, but as I understand it (assuming I wasn’t misled by my reading), when households are feeding into the electrical grid (instead of just the utility company), an electrical utility worker who is working on something and has turned off power from the power plant coming down their particular line can be surprised/hurt by electricity coming from the residential side of things if it’s feeding into the grid and isn’t supposed to be.
So that’s why areas where solar power on residential homes are regulating solar installs if the electricity from the solar power feeds into the larger grid, so folks working on the lines have a clear idea of what’s being fed into them.
MrHydrohead has a series of videos on their multi-year renovation project for their off grid domestic micro hydro power system. While not taking an existing on grid system off grid they renovate their failing off grid hydro system from 1996.
There are 3 short project summary videos the have notes that show which project video covers the topic they are discussing so you can find more information. One Two and Three
I think if they did, I’m not super sure they’d be the type of person posting on social media, but 🤷
I thought this was super-cool–full build video to make a little water turbine to generate electricity.
This is cool, and really like the idea behind the channel. The concept and design of this particular method of using water as a gravity to spin a turbine via fan seems less efficient than a water wheel though, no? Horizontal spin vs vertical. Maybe I’m missing something.
The guy’s channel revolves around solutions that are super-cheap so that someone handy in a poor country can easily source the materials to build the thing. So I imagine some of his design decisions are based on his knowledge of what materials are locally available to relatively poor people in various places in Africa, or Panema, or Tibet, or wherever.
I was watching another one of his videos, and he was trying to get a bike chain to act as a belt for his wind turbine, and his rationale was that bike chains are easily accessible in poor countries, but he had to fall back on a car drive belt that was cut down and modified because he couldn’t get his first option to work.
Oh, for sure. I watched quite a few of his videos after seeing this one. They had a lot of problems getting the fan in this type of layout to stay in one piece, so that’s why I thought it was maybe not quite the most efficient way to spin something with water. I guess the vertical shaft and fan design has a faster spin potential than a horizontal force applied.
