Literally yesterday i pitched to my wife that i cant wait till i have some personal drone that ca evaporate and deflect raindrops before they fall on me. Essentially creating a flying rain shield.

Did not expect to be a step closer today already.

Are you meaning using a laser on the drone to evaporate the drops? That causes issues. Though maybe one could just put a waterproof shield on a drone with a particularly strong motor to resist winds, to just act like a regular umbrella that you don't have to carry. Seems impractically noisy and power hungry though

The best part is when it runs out of battery and lands right on your head.

I don’t think i mean all that much. Its mostly a fantasy/dream cause I regularly have to walk through rain.

I am not expecting anything like it in at least 15 years but as fan of the whole “post-scarcity ai automated luxury gay space communism“ i can imagine a few scifi ways to do it like directly shooting individual nano-engineered artificial photons at every single drop that is calculated to otherwise hit me.

Cool idea, but I'll just go with umbrella.

Eventually when the cool factor of light umbrellas wears off, traditional retro umbrellas will become cool again. But you can't beat the convenience of light-based rain protection
