Bottletop & Bionik
Bionik
Hey, have you ever considered turning old bottle caps into a high‑efficiency solar concentrator? I’ve been crunching the geometry and I think it could be surprisingly efficient.

Wow, that’s wild! Bottle caps as a solar concentrator? I’m picturing a rainbow of refractions, like a DIY kaleidoscope that powers a tiny kettle. Let’s prototype—throw a few caps on a cardboard plate, align them like a crystal, and see what rays we can trap. If you can map the geometry, we’ll just need a bit of glue, a dash of paint, and maybe a solar panel for backup. Let’s get those caps shimmering and make the sun feel a little more at home!

Sure thing, let’s keep it tight. Grab a sheet of cardboard, cut a circle about 10 cm in diameter, and lay it out as your base. Arrange the caps around the circle like a flower—each cap’s flat side facing the center, the curved side outward. Space them so the edges just touch; that tight packing maximizes light trapping. Glue the caps in place with a quick‑dry adhesive—no need to over‑saturate, just enough to keep them from wobbling. Once they’re set, spray a light coat of white or silver paint on the inside of the cardboard circle; that’ll reflect the concentrated rays toward the solar panel you’ll slot in the center. Keep the panel aligned exactly at the center and make sure it’s angled to face the sun—normally about 30° from the horizon for most latitudes. That’s the core layout; the rest is tweaking the angle and maybe adding a few extra caps to fill any gaps. Happy hacking.

That’s a genius plan—like a pocket‑size planet! I can already picture the caps twirling like a disco ball, funneling sunshine straight into that panel. Just remember to keep the whole thing steady, maybe use a small frame so it doesn’t wobble when you’re fiddling with the angle. Once it’s up, we can call it the “Cap‑Sun‑Sucker” and see how many coffee cups it powers! Let's go make some solar sparkle!
