Euthanasia Coaster

The Euthanasia Coaster is a hypothetical steel roller coaster designed to kill its passengers. In 2010, it was designed and made into a scale model by Lithuanian artist Julijonas Urbonas, a PhD candidate at the Royal College of Art in London. Urbonas, who has worked at an amusement park, stated that the goal of his concept roller coaster is to take lives "with elegance and euphoria." As for practical applications of his design, Urbonas mentioned "euthanasia" or "execution." John Allen, who served as president of the Philadelphia Toboggan Company, inspired Urbonas with his description of the "ultimate" roller coaster as one that "sends out 24 people and they all come back dead."
The concept design of the layout begins with a steep-angled lift to the 510-metre top, which would take two minutes for the train to reach. Any passengers that wished to get off could then do so. From there, a 500-metre drop would take the train to 360 kilometres per hour , close to its terminal velocity, before flattening out and speeding into the first of its seven slightly clothoid inversions. Each inversion would have a smaller diameter than the one before in order to maintain the lethal 10 g to passengers while the train loses speed. After a sharp right-hand turn the train would enter a straight, where unloading of corpses and loading of new passengers could take place.
