This is a water-activated flashlight shell designed for magnesium-air battery modules. Add saltwater to power the internal metal-air cell — no charging, no regular batteries needed.
The 3D model is intended for demonstration, prototyping, and educational purposes. Ideal for use in emergency kits, camping gear, and off-grid lighting systems.
📦 Model Details:
Designed to fit a magnesium-air battery cell
Diameter: 50mm (head), 39mm (tail)
Length: 187mm

🌊 How It Works
Add saltwater (3.5–25% concentration) into the internal electrolyte chamber. The magnesium plate reacts to generate electricity and lights the LED — usable for up to 30 hours per activation.
🛠 Recommended Use
Emergency preparedness
