This new lighting design was posted on Treehugger by Petz Scholtus. It’s essentially a streetlamp that is surrounded by a tubular tank full of micro-algae. The algae need light and carbon dioxide to survive, and while the light is part of the structure, they pull their CO2 out of the air, purifying it. The inventor claims that the micro-algae will pull as much CO2 out of the air in a year as an average tree will over its entire lifetime. I can’t say I know much about the science, so I’m going to trust this guy; what I know is the design, and so I want to discuss that. The light coming from this thing is sort of cool and eerie, but not terribly strong. It could be used for pedestrian-scale lighting and architectural accents, but I’m not sure how feasible it would be for roadway lighting, as the video…
