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

    I wonder if this could be used with existing solar arrays to kind of use the panels as rain collectors to funnel into something like this. Would have the benefit of giving some extra power when solar is weakest.

      Yeah, seems like having solar, wind, and rain energy gathering devices would be useful for small-scale applications.

        You cant gather more energy out of the rain than its potential energy from you roof to the ground.

        Even at 100% efficiency it wont do anything.

            No, true.

            But factoring CO2 emitted from manufacturing + transportation from factory to your house, it will be net negative in emission. Even from transportation alone.

              Actually, Randall Munroe did the calculations for his “What If” series. It is net positive in cost over a long enough time, which means that it will eventually be net positive in emissions, assuming it lasts long enough.

                Yeah, the line for when its net positive is key. Otherwise we cant really draw conclusions.
