    Three years ago EEVBlog already published a Video why this is a terrible idea: https://youtu.be/7vItnxhWRqw

    Im not convinced much has changed since then. As a Swiss citizen it’s a bit disappointing that a apparent cash grab like this is possible.

      And this is why they only put 100m of panels, to test and validate the idea before commiting to any large scale project. As a swiss citizen too, I’m on the contrary quite happy to see those test projects to give a chance to new technologies (or ways to utilize said technologies) before any real investment.

      Tbh this video has poor arguments:

      • solar roads startups closed (no shit sherlock. Many startups close everyday)
      • dust and wires (sure. However this is an engineering problem and can be solced)
      • south corea does it as roof top (what’s the point here?) And that’s it. No real argumenr visible. Just a video for getting ad fees imho.

        This guy was never to Switzerland.

        Dust --> attach a brush infront of the train

        Im not sure we use the machine that he showed in the video to replace the gravel. At the same time it looks like the tracks stay untouched. Its not something that is done often.

        He talks about huge shipments of coal in Switzerland xd WHAT THE HELLY ??!!(the 1800s called, they want their environmental policy back)

        He wants private citizens to plaster their roofs and their soil with solar. Well they can i guess but its their decision. Just know that the cows in Switzerland usually graze on grass. The railway is 100% Eidgenossen owned.

        2% is 2%. People cry about every Rappen on the powerbill. I wouldnt mind paying 2% less and im not even a company.

        In the comments they talk about the toilet releasing the waste on the tracks. In Switzerlands trains theres WC’s (water closets). So the sun will evaporate the waste. Also we dont want to eat from the panels its just to generate electricity.

        So i found an argument against every argument of his and it took me 10 minutes.

        I respect the effort tho it was fun to watch.

              I don’t know whether their owners track their production for estimating ROI, but I’m getting 1.7 MWh/year from a 2 kWp DIY in a nonoptimal orientation with some shading, which is worth it at 0.3 EUR/kWh (ok, if your meter can’t run backwards you will need some storage, which has also a cost).
