A Liquid Tree? Scientists in Serbia Make Incredible Innovation

Dr. Ivan Spasojevic, Ph.D. in Biophysical sciences, and one of the authors on the project from the Institute for Multidisciplinary Research at the University of Belgrade, developed an innovative tool for reducing greenhouse gas emissions and improving air quality: the liquid tree. Also dubbed LIQUID 3, the novel creation is Serbia’s first urban photo-bioreactor, a solution in the fight for clean air. It contains six hundred litres of water and works by using microalgae to bind carbon dioxide and produce pure oxygen through photosynthesis.

The microalgae replace two 10-year-old trees or 200 square meters of lawn. . The advantage of microalgae is that it is 10 to 50 times more efficient than trees. 

Very interesting, especially in urban contexts that can’t support / be reconfigured to support more trees.

I imagine a Solarpunk world where each one of these is sculptural - a work of public art.
