> It’s a 3-D printed capsule, activated from the inside by the person intending to die. The machine can be towed anywhere for the death. It can be in an idyllic outdoor setting or in the premises of an assisted suicide organisation, for example.

> The person will get into the capsule and lie down. It’s very comfortable. They will be asked a number of questions and when they have answered, they may press the button inside the capsule activating the mechanism in their own time.

> The capsule is sitting on a piece of equipment that will flood the interior with nitrogen, rapidly reducing the oxygen level to 1 per cent from 21 per cent. The person will feel a little disoriented and may feel slightly euphoric before they lose consciousness. The whole thing takes about 30 seconds. Death takes place through hypoxia and hypocapnia, oxygen and carbon dioxide deprivation, respectively. There is no panic, no choking feeling.
