- Non-existant: A two-gas system would be enough trouble that no one
- is looking into it. As for 1 atm, it really isn't necessary: At 8.5
- psi, you don't have problems with pre-breathing or the bends anymore.
- High pressures do, however, usually limit the mobility/flexability of
- a suit. The current (unfunded) goal is for a 8.5 psi "no pre-breath"
- pure-oxygen suit. One of the proposed designs (the Ames Hard Suit)
- doesn't suffer at high pressures, so in theory it could go all
- the way up to one atmosphere (although this isn't currently
- planned for...)
