| Jun 23, 2015 at 4:52 | comment | added | Mike Nichols | @Burki Increasing the pressure of the atmosphere will increase the buoyancy of a lifting gas linearly. Doubling the pressure of the atmosphere will double the lifting power. This is because the buoyancy is related to the difference in densities between the air and the lifting gas. By doubling the pressure you double the densities of both and thereby double the difference between them. en.wikipedia.org/wiki/Lifting_gas | |

| Jun 22, 2015 at 18:15 | comment | added | Henry Taylor | Another way to achieve what you desire is decrease the quantity of lifting gas within the bag without decreasing its size or weight. With our current science, we use the pressure of lifting gas to maintain the inflation of the bag. If instead, you somehow froze all the molecules of the bag in their current shape (maybe a stasis field), you could then pump all the air out, leaving a vacuum which would provide maximum potential lift for your planet's existing atmospheric pressure. I made this a comment because it attempts to answer your need rather than your question. | |

| Jun 22, 2015 at 14:05 | comment | added | Burki | you would need (more) heavy gases in your atmosphere. Increasing the pressure would not help, since you would have to increase the pressure of your lifting gas (or compensate with a more rigid, and thus heavier, shell) | |
