The Goodyear blimp Columbia (see Fig. l5-20) is cruising slowly at low altitude, filled as usual with helium gas. Its maximum useful payload, including crew and cargo, is 1280 kg. How much more payload could the Columbia carry if you replaced the helium with hydrogen? Why not do it? The volume of the helium-filled interior space is 5OOO  m3. The density of helium gas is 0.160 kg/m3 and the density of hydrogen is 0.0810 kg/m3.
