Even looking at the actual paper [1] I think no raindrop ever touched such a device during their experiments? In their extremely brief experiments section, they say "The water droplet was generated by the commercial infusion sets" which I think means ... they sprayed one of their devices with a hose? There's nothing which seems to indicate anything about droplet size, or rate of simulated rain. Did they use a pressure washer? Not describing the actual amount of "rain" they sprayed on the device also makes it unclear whether their "5 times higher" number is an apples to apples comparison, esp since 200W is a _lot_. > When the area of the raindrop energy harvesting device is 15 × 15 cm2, the peak power output of BAGs is nearly 5 times higher than that of the conventional large-area raindrop energy with the same size, reaching 200 W/m2 I think perhaps the most important sentence on the posted article is (emphasis mine): > Christopher Plain is a _Science Fiction and Fantasy novelist_ and Head Science Writer at The Debrief.
