The generator is loaded with four litres of LN2. On activation, nitrogen will be produced at the rate of ~35 litres/ sec for ~4 minutes. Within 30 seconds, the oxygen concentration in the capsule is < 5%.
Sarco has been created for use by adults of sound mind: peo- ple who have ‘mental capacity’. At the current time, mental capacity assessment is conducted by a psychiatric review (by a psychiatrist). Exit believes that this person-to-person assess- ment could be replaced with an online artificial intelligence (AI) test.
On successful completion of the AI test, the user could be is- sued with an entry code that activates the keypad. The code could be time-restricted, expiring after 24 hours. The AI test would then need to be retaken and a new code issued. The AI component of mental capacity testing will be addressed at a future stage.
The Coffin
While the Sarco capsule was initially conceived as a coffin (suitable for burial), the concept is now more centred on a make-once, use-often approach: especially given the increas- ingly ecologically-friendly means of body disposal that are be- coming available (eg. aquamation).
