SOLAR BOTTLE BULBS

 A solar-powered light made of used plastic bottles is called a solar bottle lamp. By replacing the bottles' old plastic caps with 3D printed solar lamps, the concept aims to repurpose discarded plastic bottles. Almost all soft drink bottles can fit it in.

Recycling certainly contributes to the sustainability of plastics, but occasionally recycling may not be as carbon friendly as we would like it to be, so why not try upcycling? Upcycling is the act of giving goods a new life by utilizing them in a way they were not necessary meant to be used, as opposed to throwing them out or having them recycled.

Even in regions with limited access to dependable energy, sunlight is still available. A single, straight, narrow light beam would enter through the hole alone, but the water in the Solar Bottle Bulb bends the light so that it may illuminate a wider area from all sides. By limiting the growth of algae, the bleach maintains the water clean.

How does a light in a bottle function?

Depending on the quantity of solar insolation available, the water's refractive qualities guarantee that the sunlight that enters the bottle becomes omnidirectional like an electric light bulb and emits the same amount of light as a 40–60 W incandescent bulb.

Innovative lighting solutions for households in places without energy include solar bottle lights. Aquatic Bleach The water light bulb is easy to use and affordable. Clean water and 10 milliliters of bleach are added to a 2 liter bottle to slow the formation of algae over time. The benefit of employing solar water lamps over just drilling holes in the roof is that sunlight coming through a hole illuminates a small portion of the room like a spotlight. More light is captured by placing a water-filled bottle in the hole because light changes direction as it passes through denser than air materials like water.
