Application

• Eco friendly street lighting

Description

In the environment, algae can be found in ponds, lakes, streams, and oceans, but for a variety of applications (not just street lighting), algae are often intentionally grown up in ponds and farmed.One thing that most algae have in common is that they use photosynthesis to obtain their energy. Photosynthesis is the process by which organisms use sunlight to convert carbon dioxide and water into oxygen and sugars, which organisms use for energy. Effectively, photosynthesis allows the algae to store light energy in a form of chemical energy that they can use – or that ingenious scientists can convert to electricity.

Pathway Description:

The process used in this project involves algae's natural photosynthesis to convert sunlight, carbon dioxide, and water into energy. The algae produce chemical energy, which is captured by electrodes to recharge a battery. This stored energy powers the light source in the lamp. The process allows the lamp to remove carbon dioxide from the atmosphere, contributing to environmental sustainability.
