Nitrogen Asphyxiation - simply the cleanest, cheapest, safest, painless way to execute someone. Strap the condemned down, place a mouth and nose breathing mask with two feeds. Feed one is normal air, feed two is 99.5% industrial nitrogen. Valve between the two should be either 1 or 2 and should be triggered electronically.
Add a brain wave monitor to determine when the brain activity stops. Set the valve to switch between 1 and 2 when the clock runs out. Wait till there is no more brain wave activity for 5 min. Done. The condemned just goes to sleep.
“Nitrogen Asphyxiation”
Three employees working in a windowless room at a facility I worked at died this way. They were unaware there was a nitrogen leak. No symptoms at all, apparently.
I suspect, though, that there must be some legal reason that executions are carried out the way they are. Any lawyer types out there who can explain why there’s a dearth of options?
I was nearly asphyxiated by nitrogen displacing my breathing space once.
I didn't have a clue till I started feeling light headed and getting tunnel vision.
Fortunately I recognized it and made it to a nearby door.
Absolutely no pain or shortness of breath involved.
