The Peaceful Pill eHandbook Why Liquid Nitrogen (LN2)?
If one is to fill a volume much larger than a plastic bag quickly enough to induce a rapid loss of consciousness, then com- pressed gas is not an option. Compressed gas is too bulky and, on rapid release, far too noisy. Liquid Nitrogen, however, of- fers a very effective alternative. The Sarco uses just over 4 litres of LN2. On activation, the oxygen level within the cap- sule will silently drop to less than five percent in less than one minute. On deep inspiration, loss of consciousness and death will occur within a few minutes.
The Sarco base and capsule are 3D-printed in two parts. The capsule is biodegradable and able to be used as a coffin. The base containing the liquid Nitrogen evaporator can be reused.
Access to the Sarco will ultimately require the successful com- pletion of an online medical capacity test (using artificial in- telligence). This test is still in development and is likely to be the final stage of the Sarco project. Successful completion of the mental capacity test will generate a four-digit access code. On entry, activation will be by touch screen. A stop button and a fracture panel in the canopy will allow for any last minute reversal of decision.
Manufacture, Distribution & Plans
The first Sarco was 3D-printed in Haarlem, Netherlands be- tween November 2018 and May 2019. As large-scale, 3D printers are not yet easily accessible, Exit is currently explor- ing the ways and means of pre-manufactured Sarcos being made available. Once 3D printers are ubiquitous, the Sarco plans will be published in the eHandbook. The costs for a Sar- co will then stem only from the cost of the 3D-printing and the cost of obtaining the liquid nitrogen or LN2.
