"chemical solutions stimulate algae’s luciferase-luciferin reaction... 250 mL concentrated culture produces roughly 1,335 lumens, nearly identical to 100W (almost 100% light rather than heat) incandescent bulb... absorb CO2 during day/ glow at night... naturally shut down glow during day saving energy... smart culture systems automatically feed/ refresh for months/ years of life...  Hamburg/ Paris algae-powered streetlight pilot programs... replace lightbulbs, autonomous robotics, water toxicity/ nutrient level sensor"
