Scientists at Binghamton University have invented an artificial plant that can simultaneously clean indoor air while generating electricity.
The artificial plant uses biological solar cells and photosynthetic bacteria to remove carbon dioxide from the air and produce oxygen, similar to natural plants. However, it is much more efficient at CO2 removal than natural plants.
It works by using light to drive photosynthesis in the bacterial cells. In tests, it achieved a 90% reduction in indoor CO2 levels, far exceeding the 10% reduction of natural plants.
When multiple leaves are connected, the plant can produce enough electricity (around 140 microwatts) to power a smartphone by generating a voltage of 2.7V.
It requires similar maintenance as plants, like water and nutrients. Researchers hope to further optimize it to require less upkeep over time.
The researchers believe with refinement, these artificial plants could be incorporated into homes to both improve air quality and provide sustainable energy on a small scale. It represents a potential “dual-function system” according to the scientists.
