  • Hydropower has been with us for millennia, but the 20th Century race to build huge centralised hydropower dams in many parts of the world has caused untold environmental damage. Now a new micro-hydropower technology is working with the natural flow of water and wildlife rather than against it, to bring much needed constant baseload power to off grid areas in remote areas of developing nations.

    There are weirs for old mill waterwheels all over the UK (and presumably the rest of Europe). The waterwheels and their mills have all shut down long ago, so I was wondering if this technology could be used to repurpose this existing infrastructure. Most weirs already have salmon leaps built in and are 100+ years old, so the environmental cost is even less. Whilst all these sites will already be grid connected it could still be a way to provide extra reliable energy.

      @@b00marrows There are a few YT videos on old UK mills converted to generate power, both as private installations and as community projects. The benefit is that as the waterwheel is now generating an income, it stays serviced and becomes a tourist attraction drawing business to the area too. Depending on the state of the waterwheel, it can either be as simple as fitting some pulleys to the shaft coming in through the wall, or a costly restoration of the waterway and wheel with historical accuracy.

    Turgo turbines are well known, the main issues are reliability and maintainability. I do wonder why so many of these installations use a single unit rather than a pair of smaller ones. If you have a single turbine and it needs maintenance then you lose all power whereas if you have more than one you can shut them down separately and the parts are smaller meaning it is more likely that the locals can handle repairs themselves without needing heavy equipment.

      This is not a Turgo turbine!
      Turgo's need 15m head to become efficient and direct "jets" of water at the turbine wheel. This works by getting the whole mass of water to spin and the turbine extracts that spinning motion and adds it to the gravitic energy from the water falling through it! The revolutions of Turgo's are a magnitude higher than this too so you would expect bearing replacement to be less too!

      Micro hydropower is an attractive option for rural electrification in many countries because it can be implemented with little infrastructure. Turgo turbines are one type of micro hydropower turbine, and they are well known for their reliability and maintainability. However, there are some issues that need to be addressed in order to make Turgo turbines more reliable and easier to maintain.
      One issue is the design of the turbine blades. The blades are subject to wear and tear, and they must be repaired or replaced regularly. Another issue is the bearings, which need to be regularly lubricated and replaced. Finally, the generator must be regularly serviced in order to prevent damage from dirt and debris.
      With proper maintenance, Turgo turbines can provide years of reliable service. However, if they are not properly maintained, they can become unreliable and difficult to repair.

Solution would be to increase electricity cost (which is often hidden or not paid, like carbon tax).

When I inquired about this, we pulled over to one of these huts advertising "cold bia". The owner took us down to the river where the outboard was off but the prop was turning in the current. The alternator was providing current to a battery which in turn powered a refrigerator full of cold beverages. He produced a product that thirsty dual sporters want and that helped support his family. Plus, he still has a boat to do portaging work. Micro hydro at it's best.

    These look great for very rural areas without deep freezes and with consistent stream flow. However, the amount of energy you can get out of a given volume of water is proportional (approximately) to the difference in height between the inlet and outlet. This is why very tall dams get built, more power for a given water flow. So while these can help, they won't "replace the grid" in any area with significant power needs.
    In areas where there isn't a large drop in elevation, you are limited to micro-hydro and these look good for that as long as only part of the stream's flow is diverted and the majority of the water is left in the original channel the environment isn't changed too much.

    The comparison to the four tennis courts worth of solar installation is a bit unfair. The solar panels don't require any more space than they take up to function. The turbine is fed by a river that gets its water from a very large area in the mountains. That explains why a solution like that won't scale up very well. When you consider the entire area of land needed to provide the energy, you don't get very many watts per square meter.

      I can see the angle you are coming from. Honestly I think you raise quite a valid point, this definitely can't work everywhere. Although, these turbines solve the problem of intermittent power attributed to solar panels.
      These turbines work off of the principal that they aren't leaving a large, man-made footprint on the planet.
      When taking that into consideration, I feel that the length of the river is irrelevant considering that where these turbines will work are places that no one is going to remove the river unless you are planning on putting a large scale hydro-electric dam on site.
      I would also like to point out that I disagree with Sebastian as I don't think those comparisons of logic made much sense. As I said, I feel you raised a valid point. However, I don't think anyone is going to remove a river in the effort of ecological conservation.

Eventually I did, but the river is just a tiny stream, although I'll take the free water to irrigate my lands, thank you very much. I did have to pay a small premium for the land, being close to the river, so there's that hidden cost.

People living near rivers made their own hydro, usually from the alternators taken from their standed cars and DIY water wheels, mounted on a small anchored floating raft in midstream, and driven by the flow past the wheel. One design looked like a Mississippi stern-wheel paddle steamer heading upstream "pulled" by its anchor rope.
    People could light their homes with 12V lights (not at full mains brightness but still usable) run a radio. Beauty was the dead car also had a regulator and battery that could be repurposed to control the output of the alternator over a huge range of revs.
    Not efficient. Not cost effective in normal life, but in a situation where normal city utilities failed it made survival that bit more comfortable and using only what was already present in an city when it went off grid...

    This is definitely a contender for becoming the most popular type of hydro generation in the future!
    A string of these spreading the length of a river would give a large output for a low (relative of course) cost. It would also have the advantage, if interlinked, to allowing interchangeability!
    If you (or a group of you) own say a dozen of these you could afford to have spares on hand at 1/12th of the cost of only owning one. This would allow you to take one out of production and replace it with the spare unit and repair/ replace the original at leisure!
    The relatively low cost could allow communities to grow their production or just make a private distribution network and keep it all in house. Flexibility!
    As has been commented by others on this thread there are many ex-watermills around the UK (and other countries) that could be repurposed to give a more diversified power network, thus stabilizing the grid. This can be eather load balancing or frequency stabilization. That has got to be better than the current idea of having generators dotted along the motorway network to cover peak loads ...... or battery farms!
    TBH I can see the case for firms setting up to do this as a business model. Back in the day (pre-privatization) Norweb used to have it's own bio powered electricity generation plants (methane fueled engines and Hydro) .... but all that was lost in the sell off by United Utilities! This was one of the reasons electricity prices stayed static for so long. All the money generated from the different parts of the company went directly to offset the cost of purchasing energy from the generating companies! I am certain the other REC's did the same.

    10 years ago my company manufactured a 5kW, low head, small scale hydrodynamic screw at relatively low cost which is still working! With proper maintenance it will continue to work for many years to come. I think a major problem is the need for an abstraction licence which requires many hoops to be hopped through! Great vid!

    Very cool you made a video about that. I saw that about a year ago and i love that system. It is perfect for many places that has even a medium flow of water with a rather low hight drop. I was even think to put one at my fathers place where there is a water stream in falls-winter-spring.
    Good to know they are expanding and helping for these good causes!

    I live in British Columbia, Canada and currently there is a large dam, called Site C, under construction on the Peace River. It will provide 1100 megawatts of capacity and 5100 gigawatt hours of electricity each year. The project has been controversial with cost overruns and conflict with local citizens, including Indigenous First Nations people. BC is fortunate to have a large percentage of its electricity supplied by hydro and its relatively low GHG emmissions, but there is always an environmental price to pay regardless of the type of generation. I'm very conflicted by site C, but long term I guess it's for the best, although it's easy for me to say as I haven't been displaced by the flooding. I have really enjoyed your channel and am glad I discovered it

    So I live close to a river and now thinking about acquiring a lot close enough I could try this. Sounds really good. Very interesting video. Thanks for bringing so much thoughtful content.

    Really enjoyed this one, gives us hope that there are brilliant people out there striving to overcome and actually thinking about the negative impacts of renewable energy systems in order to work with nature not against it👏
