In an experiment, one tube produced 440 microwatts. When the researchers used four tubes at once, they could power 12 LEDs for 20 seconds.

This isn’t a terrible idea, and it could be useful as a source of emergency power in places that have high rainfall (paired with a battery system). From my background, I just don’t see it as viable for general use.
I also wonder about stacking them, particularly in places with a lot of rainfall.
Somewhere that has lots of drop, sure. But hydro relies on head pressure. Which is why most dams are a resevoir with multiple turbines.
