A balloon for supporting a load 5 in the air comprises a primary compartment 4 for receiving a first gas and one or more secondary compartments 3, for receiving a second gas. The secondary compartments are contained within the primary compartment and supported away from the wall 1 of the primary compartment by support means 20 such that when the compartments are filled with gas the first gas completely surrounds the secondary compartment(s). The supports may be made from fibre-reinforced polymer, carbon fibre-reinforced polymer or aluminium. Surfaces of the primary and secondary compartments may be coated with a non-stick material such as PTFE. The balloon may be used to suspend a wind turbine. |
