A drone can lift itself only through the power of a solar panel
(thelemmy.club)
Some amazing engineer built a drone that can lift its own weight using only the electric power that it gets from an on-board solar panel and nothing else (no battery).

I wonder if a large network of solar powered drones could one day be deployed to counter the affects of urban heat islands.
Yeah, that seems like a better solution than trees.
I would prefer forest canopies...
Doubt it. The energy collected by the panel is turned into thermal energy by the spinning propellers. Maybe if they can bank some of it in a battery to use later?
I meant as mobile canopies that could be deployed to shade urban areas during extreme heat events.
