This is an eco-friendly LED lamp jointly designed by scientists from Yansei and Stanford University. The lamp's electric energy is obtained through biological reactions. A 30-nanometer-wide electrode is inserted into a bottle of seaweed chloroplast in a conical bottle. Seaweeds produce electricity when they carry out photosynthesis, and seaweeds reproduce very quickly. If they are placed in the sun to supply carbon dioxide, water can grow rapidly. This device can store the current generated by it and provide it to LED lamps for use as electrical energy lighting.
