Google is Killing Its Solar-Powered Internet Drone Program (businessinsider.com)
An anonymous reader writes: Google's "moonshot" X division is ending its Titan drone program, which planned to use solar-powered drones to beam internet down to earth. Google bought Titan Aerospace in 2014. The company was developing solar-powered drones that could fly for several days at a time and take images of earth or beam down internet. When Google reorganized into Alphabet in 2015, Titan was folded into X, the Alphabet division that focuses on wild tech projects in hopes of stumbling on the next big thing.
Cleaning is important because it keeps the airfoil surfaces aerodynamically sound. Even birds groom themselves to stay in good shape
So the answer is obvious - we bio-engineer birds that clean themselves - but ALSO clean the drones!
Or we develop a drone with a tongue, basically go with whichever idea can get grants or Google pay money.
