A system and method is described generally for providing a high altitude conduit the high altitude conduit includes a first material layer forming an elongated duct. The high altitude conduit also includes a second material layer outside the first material layer. The second material layer defines a space between the second material layer and the first material layer. A gas has a density that is less dense than that of the atmosphere outside of the second material layer. The gas is disposed in the space between the first and the second layer. An introducer is configured to provide the gas into the space between the first material layer and the second material layer. The gas causes the conduit to extend in an approximately upright orientation.
