The country's medical review board has authorized the use of the Sarco Suicide Pod, which is a 3-D-printed portable coffin-like capsule with windows that can be transported to a tranquil place for a person's final moments of life. 

Conventional assisted-suicide methods have generally involved a chemical substance. Inventor Philip Nitschke of Exit International told the website SwissInfo.ch that his "death pod" offers a different approach. "We want to remove any kind of psychiatric review from the process and allow the individual to control the method themselves," he said. "Our aim is to develop an artificial-intelligence screening system to establish the person's mental capacity. Naturally, there is a lot of skepticism, especially on the part of psychiatrists."

The pod can be activated from inside and can give the person intending to die various options for where they want to be for their final moments. "The machine can be towed anywhere for the death," he said. "It can be in an idyllic outdoor setting or in the premises of an assisted-suicide organization, for example."

To qualify to use the pod, the person who wants to die must answer an online survey that is meant to prove whether they are making the decision of their own accord. If they pass, they will be told the location of the pod and given an access code.

Once inside, the person intending to end their life will have to answer pre-recorded questions and press a button that will start the process of flooding the interior with nitrogen, which will quickly reduce the oxygen level inside from 21 percent to 1 percent. "The person will get into the capsule and lie down," he said, adding, "It's very comfortable."
