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

    third paragraph:

    Normally, when we generate electricity from water, we use the movement of lots of it to drive a turbine in a river, the sea or even in drinking water pipes. But water flowing over an electrically conductive surface can generate its own electrical charge through a process called charge separation. This is driven by positively charged protons of the water molecules staying in the liquid and negatively charged electrons being donated to the surface, much as you can generate static electricity by rubbing a balloon on your hair.

    charge separation is a lot more than just photoinduced charge separation

      If that was a real thing, at least in charges strong enough to harness for work, surely we wouldn’t ground sensitive electronics to metal water pipes. And metal fuel containers would be spontaneously exploding all the time. I can’t find any evidence of this phenomenon anywhere but in this article. Can you provide a source?
