Scientists from Binghamton University in New York have created an artificial plant capable of cleaning indoor air and generating electricity. This innovative device, designed “for fun” by the research team, uses five biological solar cells powered by photosynthetic bacteria. Initially a playful experiment, the project evolved into a practical invention with promising real-world applications.
The proof-of-concept plant features five artificial leaves that produce electricity and oxygen while efficiently removing carbon dioxide. According to the researchers, the device performs far better than natural plants, removing up to 90% of indoor CO2, compared to the 10% reduction achieved by real plants.
The scientists highlighted that traditional methods of reducing CO2, like ventilation and filtration, are becoming less effective due to rising outdoor CO2 levels. This artificial plant, however, offers a sustainable alternative, using indoor light to drive photosynthesis.
Similar to natural plants, the artificial leaf requires water and nutrients. However, future models may reduce maintenance needs by incorporating multiple bacteria species. The research team is also working on scaling up the technology for broader use.
The plant generates enough electricity to power small devices like smartphones, achieving a maximum power of 140 µW and an open-circuit voltage of 2.7V. Professor Seokheun Choi, from Binghamton University, expressed his hopes for the future, stating that these artificial plants could one day become a household staple.
The study, titled Cyanobacterial Artificial Plants for Enhanced Indoor Carbon Capture and Utilisation, was published in Advanced Sustainable Systems.
