Alien Wind Power – Grok via Astrobiology.com We suggest that the large-scale deployment of wind turbines on an M-dwarf planet could produce observable technosignatures. Motivated by observations of hypersonic wind

Generic structure of the taxonomy of potential biosignatures (PB). The taxonomy consists of three generic categories (chemistry, structure, activity) thought to represent universal attributes of life. Each category comprises two
