Binghamton University Researchers Develop Bacteria-Powered Indoor Plants.
Researchers at Binghamton University in New York are transforming their work on bacteria-powered biobatteries into artificial indoor plants that produce oxygen and generate electricity.
Professor Seokheun Choi and Ph.D. student Maryam Rezaie initially created an artificial leaf. They later expanded their project to a plant with five leaves after discovering the leaf could capture carbon dioxide and produce oxygen.
Choi highlights that building materials, carpets, and daily activities like cooking can release harmful substances. Their research indicates that the World Health Organization (WHO) views poor air quality as the top environmental health risk globally.
The artificial plants utilize cyanobacterial CO2 fixation to generate oxygen and bioelectricity through photosynthesis, functioning as a compact version of carbon capture technology for indoor use.
These plants rely on indoor light for photosynthesis, achieving a 90% reduction in carbon dioxide levels. Choi notes that while power generation is a secondary benefit, he aims to improve the technology to produce over 1 milliwatt, potentially enabling it to charge devices like mobile phones.
The team is also exploring upgrades, such as incorporating multiple bacteria species for long-term viability and minimizing maintenance needs.
Globally, researchers are seeking innovative solutions for indoor air quality, especially since the COVID-19 pandemic. Professor Brendan Crabb from the Burnet Institute stated that Australians spend up to 90% of their time indoors, and better air quality can reduce illness spread, increase productivity, and foster community support.
“With some fine-tuning, these artificial plants could be part of every household,” Choi says. “The benefits of this idea are clear.”
