Hello, Willy! Glad you didn’t fall off the edge of the planet!
While not optimal, you can try to shield the VapCap by using your body away from the sun, and wind.
Turn away and try to minimize the intensity of the source by blocking it with your body, and clothes.
A pocketable induction tube would help solve the problem. Until then, I sometimes use a torch with a nozzle in which the tip of the VapCap is inserted, thus being “windproof”. Downside, it is designed as a tabletop model.
You may try to fashion a small cone, or cylinder to shield the tip but that could be an annoyance, and
cumbersome.
As Hogni said, I too have not had a screen fall out, if seated properly. Perhaps use a Petri dish, or small plate to minimze losing it when emptying the AVB, and making sure it is securely seated, flat.
Don’t give up the ship. Look for solutions, mi amigo.
