disco_tracy writes "Lithuanian amusement park worker and current PhD candidate in London's Royal College of Art's Design Interactions department, Julijonas Urbonas, has made a design for a hypothetical coaster that could be the future of humane euthanasia. Urbonas says that it is engineered to give a person a way to die with 'with elegance and euphoria.' From the article: 'The three-minute ride involves a long, slow, climb -- nearly a third of a mile long -- that lifts one up to a height of more than 1,600 feet, followed by a massive fall and seven strategically sized and placed loops. The final descent and series of loops take all of one minute. But the gravitational force -- 10 Gs -- from the spinning loops at 223 miles per hour in that single minute is lethal.'"
