The “Euthanasia Coaster”: Art, Ethics, and a Roller Coaster Designed to Kill

A Ride Like No Other — and Never Built In 2010 Lithuanian artist-engineer Julijonas Urbonas presented a provocative concept: a steel roller coaster engineered to end a person’s life “with elegance and euphoria.” The design (a scale model and technical sketches) proposes a 500-meter lift and a fatal series of seven decreasing-diameter inversions intended to generate sustained ~10g forces, causing prolonged cerebral hypoxia and, ultimately, death. The project is a piece of conceptual art and theoretical engineering — it was exhibited, discussed, and critiqued, but it was never constructed . Wikipedia +1 How the Concept Would Work (At a High Level) Urbonas framed the coaster as an engineered way to induce cerebral hypoxia (insufficient oxygen to the brain) by applying very high, repeated G-forces so that riders would progress through grey-out, tunnel vision, G-LOC (loss of consciousness), and — in the concept — irreversible brain oxygen deprivation. The ride’s geometry (progre...
