Basically, it's a water dish for dogs that has a cowling over it that looks kinda like half an eggshell to provide shade to keep the water cool. There's a solar panel on the outer surface, and as the sun moves, the cowling rotates around a track on the rim of the bowl, to maximize the light on the solar panel and thus maximize shade on the other side of it.-- 21 Quest, Oct 07 2023 What is the advantage over an umbrella or a fly over the water dish? Maybe incorporate a clock for the humans and/or something the dogs would like.-- minoradjustments, Oct 07 2023 An umbrella is too prone to damage from wind gusts or the dog itself being rough with it.-- 21 Quest, Oct 07 2023 Fortunately dogs tend to ignore moving bits of plastic.-- Voice, Oct 08 2023 That was a cynical voice.-- pashute, Oct 12 2023 random, halfbakery
