If you are unfamiliar with the morbid purpose of Julijonas Urbonas' Euthanasia Coaster, you should watch this short presentation which details this device's devilish purpose.
It is essentially a death machine. Designed to effectively kill numerous people in a very humane fashion. Described on his website as a hypothetic death machine in the form of a roller coaster, engineered to humanely – with elegance and euphoria – take the life of a human being.
Julijonas Urbonas was an engineer and Ph.D. candidate at the time and he conceived this idea as a unique method of mass murder. It was designed to kill using extreme height. The rider will experience a series of intensive motion elements which will induce various unique experiences: from euphoria to tunnel vision, loss of consciousness and eventually death.
It would appear the the ride upwards to the apex would take roughly 120 seconds at which point the initial downward decent would be 10 seconds. Falling at a speed close to the terminal velocity you then enter the first of a series of continuous loops. As Urbonas describes:
Breathing requires more effort, as the ribs and the rest of the internal organs are pulled down, which empties air from the lungs. But most probably you are already unconscious, as this force rushes the blood to the lower extremities of the body, thereby causing oxygen deficiency in the brain. It is exactly this cerebral suffocation, also known as cerebral hypoxia, that is going to kill you.
Considering that such a device can be easily constructed and the once taboo subject surrounding population expansion becomes increasingly familiar in our public discourse, exacerbated by global poverty, conflict, resource exploitation and disease ......how soon could we start to see such macabre manifestations in our conflict and violent prone civilization?
In addition, knowing how the principles of groupthink and mass idiocy function, we could see many voluntarily try this for entertainments value........there might possibly be a new reality series with full Network support - once society is sufficiently socially engineering to support mass euthanasia. Budweiser and the latest Apple products would be heavily advertised, paying top dollar, if fiat still exists for a 30 second clip of airtime.
