  I watched the video, and it’s pretty impressive so far, though for specific use cases i.e. not in all rivers at all spots, AT ALL. But for Fast moving spots in rivers that have the required depth (which is not a ton of depth), These seem to have a lot of potential for very low impact power harvesting with few drawbacks. They slow down the flow of water a bit but for areas that are somewhat steep that is probably more of a benefit than a drawback. They are clearly way way less impactful than for example building a dam. And so far they seem to be fairly thoughtfully designed to avoid contaminating the area or harming the existing fish and so forth.

    They slow down the flow of water a bit but for areas that are somewhat steep that is probably more of a benefit than a drawback.

    Slowing a river down raises the water level, which can risk flooding. Every section of river has to let through a certain amount of water per second, and slowing the water down means you need a bigger cross-sectional area to get the same throughput so the water level rises. This can create a feedback spiral because a higher water level slows the river down further because there is less height difference with further upstream and thus less force driving the water downstream against the friction of the riverbanks.

    Luckily it seems these turbines can be removed quickly, so unless the engineers fuck up they shouldn’t increase flood risk.

  @poVoq how can I get more information about this? I wasn't able to watch the video from Germany

    What’s really amusing about this is that the name of the YT poster is “German Science Guy”.

      @WhoIzDisIz yeah that's what I thought too ^^

  I’m all for creative ways to harness cleaner energy, but not quite sure this seems like the way. Just worried that filling waterways with a ton of small devices will end up resulting in more pollutants/microplastics down the road.
