Artificial Photosynthesis: The Key to Sustainable Life in Space Colonies.
Artificial photosynthesis may be the key to sustaining life beyond Earth, as it can produce oxygen and recycle carbon dioxide in one device using solar energy and water. This technology could complement existing life support systems and reduce the weight and volume of space exploration equipment. The devices could also be used to produce hydrogen or carbon-based fuels, opening up a green way for the production of energy-rich chemicals. The insights gained from designing and fabricating these devices could also help meet the green energy challenge on Earth.
