One of the most intriguing (but too briefly discussed) ideas at DARPATech 2007 was the use of hydrogen sulfide to induce a state of suspended animation. Such a state would primarily serve the purpose of buying time: even a brief period of suspended animation after a fatal hemorrhage would allow time to transport a fallen soldier to safety.
Hydrogen sulfide gas can shut off an organismâ''s need for oxygen and induce hibernation. Given that the toxic gas is responsible for the odor of flatulence, Iâ''m not shocked that the two are related.
This is not a new idea. Check out this February 2007 interview with Tony Tether at Danger Room for more on the topic.
