The “Euthanasia Coaster” is a hypothetical euthanasia machine in the form of a roller coaster engineered to humanely and elegantly take the life of a human being. Riding the coaster’s track, the rider is subjected to a series of intensive motion elements that induce various unique experiences: from euphoria to thrill, and from tunnel vision to loss of consciousness, and, eventually, death. This ‘kinetic sculpture’ is in fact the ultimate roller coaster: John Allen, the former president of the famed roller coaster builders Philadelphia Toboggan Company, once said that “the ultimate roller coaster is built when you send out twenty-four people and they all come back dead. This could be done, you know." From Design Interactions Research. More here.
