I made a brain storming, but hope that someone would be able to point out what I may have missed out. Assumptions - atmospheric pressure is 3 atm, but molar concentration of oxygen is comparable to earth. The rest is mostly nitrogen.
(there are a few more assumptions like tidal lock, a bit lower gravity or a bit higher CO2 concentrations, but rather skip them for now)Consequences:
1) changes in the air transport, that were mostly discussed in the following topic:
https://www.physicsforums.com/threads/dense-exoplanet-atmosphere-choice-zeppelin-vs-plane.797461/
2) Vehicles would really have to be aerodynamic and better slow because of heavy drag (unless there is some good reason to burn fuel more generously). Do I get correctly that a car designed for Earth would for the same speed use 3 times more fuel, while the same fuel efficiency would get while driving [Earth speed]/[sqroot(3)]?
3) Water boils in something like 126C degrees.
4) Maximum range of guns - divide by 3 (?), effective presumably not as much reduced because that part of effective gun range is defined by aiming problems, which would not be affected.
5) More native, airborne creatures. Earth chicken would turn into a formidable flier. ;) (any design including insect like, flying fish like)
6) Milder climate than otherwise because of heat retention and better distribution.
7) Winds with greater force (so boost for any sail ships). But shouldn't the speed actually go down?
(Any other ideas? Suggestions?)
