3E-ROI evokes the progression in human evolution as it has transitioned from a biological mode to technological. The Extrasomatic Evolution and Energy Return on Invested (3EROI) is evolution in technology and culture – evolution outside of our bodies. Advancements in technology yield increased energy efficiency, which in turn allows technology to advance further. 3E-ROI charts the evolution from sticks and stones to alloys and polymers. Standing 50 feet long, 25 feet high and incorporating dynamic light, sound, and video elements, this sculpture embodies the path of Extrasomatic Evolution and Energy Return on Invested, mimicking the exponential curves associated with our explosive growth in population and technology. 3E-ROI prompts the question: what’s next in human evolution?
