Sounds epic! Picture a tiny turbine tucked into a repurposed tin can, the water sloshing past its blades like a drumbeat. You could line it up with a small battery pack made from old phone parts, then run a LED reef light on it—give those coral buddies a glow while the tide does the work. Grab some driftwood frames for the kiosk, paint them with reef‑safe paint, and attach a solar panel on the roof to keep everything humming when the tide’s low. Just make sure the turbine’s blades aren’t too finicky; a bit of rubber for dampening won’t hurt. Ready to get your hands dirty?
