 Optimal Mixtures For Diving:
After discovering Dalton's Law, we used the Periodic Table Of Elements to create, in theory, a perfect diving gas. This is composed of: 20% O2, 20% N2, 20% Hydrogen, 20% Helium, and 20% Neon. A regular human's inhalation of air is 20% oxygen (so this mixture gives the exact amount of oxygen per breath we normally breathe). Two, Neon and Helium, out of five gasses are Nobel Gasses, meaning they won't react with any other gasses in the compound. These other molecules are common to the human body, and aren't poisonous at high pressures. Neon, a gas unfamiliar to many people, is in the atmosphere at 1 part per 55,556, and is cheap to get, because it is produced from bird guano. It is a Nobel Gas, and is non-toxic to the human body. The weight of the theoretical mixture is 11.039 Atomic Units, where a Nitrox mixture is 15.03035 Atomic Units. This means our theoretical mixture is 27% lighter than the most commonly-used diving mixture today. That is less than 3/4 as heavy! Because there are more partial pressures to compose the compound, getting
"The Bends" would also take longer. In theory, this formula is lighter, helps prevent "The Bends," and would only be slightly more expensive than the most common diving mixture today, Nitrox.
