Serg2000 is Hydro. Banned for not admitting it.
This is what I
really like about the moderation here. Nothing is ever perfect, and if one admits to an error, and promises to not repeat the problems in communication, they can get a second chance. But, if they do not and just repeat by creating a new account, they get banned. This is how it should be, because as humans, we make errors, but can also change how we interact with others. (Using a pseudonym helps with that, because it reminds one that others do not react to your
person, but to your
output. For some personality types like mine, this is very important.)
There is obviously something fishy about the project this thread is about, because of the games with the poster identity. We cannot know whether it was intentional (as in trying to use EEVblog forums as a harebrained way to gain credibility for something the authors know is basically doomed to fail), or unintentional (someone so blinded by their own idea that they cannot communicate about it without sounding like a single-minded fraudster), but the whole scheme reeks of something rotten underneath.
There are lots of projects for small-scale damless hydropower, from waterwheels to underwater stream turbines. The common factor in these is that only a tiny fraction of the energy in the water flow is harvested, so the stream/flow is minimally affected; plus the electricity output is very modest; overall, comparable to smallest wind turbines. There is nothing wrong in starting a yet another project like that, but you do need to 1) do your background work diligently, to find out about similar past projects and their wins and failures, and 2) be open about all that. None of this will be a huge commercial success, because the field –– hydropower in general –– is
centuries old by now. Everything easy or simple or obvious has been done again and again already; any successful product will have to combine the best features of both existing designs and existing manufacturing capabilities, to be successful. The project here did not do either.
(I have done some online research on underwater flow turbines, but their major problem is that any debris or water plants tend to clog them up. My root idea was a hubless turbine with permanent magnets at the tips, and the coils in the enclosing double funnel tube. For something like charging your phone from a small stream for the night when camping/trekking it should work (with very limited electricity output!), as it ends up being cleaned daily, but for anything longer-term, they just are not suitable. My own conclusion was that a portable wind turbine would perform much better, especially if you could prepend a hand-cranked gearbox in front for emergency charging.)
