On Mars or Earth, biohybrid can turn carbon dioxide into new products
Tue, 31 Mar 2020 13:00:31 EDT
Chemists have created a hybrid system of bacteria and nanowires that captures energy from sunlight and transfers it to the bacteria to turn carbon dioxide and water into organic molecules and oxygen. On Earth, such a biohybrid could remove carbon dioxide from the atmosphere. On Mars, it would provide colonists with raw material to manufacture organic compounds ranging from fuels to drugs. The efficiency is greater than the photosynthetic efficiency of most plants.
