Innovative Algal-Based System for Nearly-free Sustainable Energy Generation and Air Purification

Abstract

In this world, living organisms such as plants, algae, and some other creatures play a crucial role in producing oxygen through the process of photosynthesis. This process relies on the unique ability of green plants and algae to use light energy to convert water, carbon dioxide, and minerals into oxygen and energy. By using the pigment chlorophyll, found within these organisms and giving them their green color, photosynthesis is carried out. During this process, these organisms absorb carbon dioxide, water, and sunlight, utilizing them to produce energy and oxygen. They retain the energy for their own use, while releasing oxygen into the environment for other living beings to consume. Algae, for instance, produce oxygen bubbles at the bottom of water bodies. These bubbles remain stationary until buoyant force, resulting from the weight of the liquid, causes them to rise. Once released, these bubbles ascend slightly to be collected and periodically or in batches released into cavities connected to a vertical belt located above the release base. This belt, connected to the cavities on one side, is pulled upward. This upward pull generates rotational mechanical movement, which is then used to produce electricity. In this way, we have successfully innovated an additional eco-friendly and free method for generating energy. This system is registered with the Portuguese Patent Office INPI under the number 119528 dated 15/06/2024.
