NOVELTY - A balloon has an outer compartment (4) bordered by an outer wall (1) and an inner wall (2), and inner compartment (3) contained within the outer compartment, and supports (20) supporting the inner compartment away from the outer wall as such that when both compartments are filled with gases, the gas, such as inert helium gas, in the outer compartment surrounds completely the inner compartment. The gas in the inner compartment may be a quench gas, preferably hydrogen.    USE - Balloon for supporting load in air. Uses include but are not limited to a wind generator (claimed) such as a wind turbine (claimed), as well as a cellular tower replacement, an observation tower, a meteorological station, a localized tri-axis reference point serving as an alternative to global positioning system, a broadcasting tower, a mobile generator, a fire-fighting apparatus, a rain-inducing technology, and a transportation device.    ADVANTAGE - The helium gas in the outer compartment serves as a barrier between the hydrogen in the inner compartment and the oxygen present in the atmosphere, ensuring that, even when an ignition source punctures the outer wall of the balloon, any flame or combustion will be extinguished upon contact with the helium, and that hydrogen will not ignite upon mixing with the oxygen. Providing two or more inner compartments for hydrogen minimizes risk of contamination by gas leakage in event of puncture of one of the compartments. Controlled descent of the balloon can be realized by venting hydrogen from one or more of the compartments rather than having to vent from a single large container. Keeping the hydrogen in separate inner compartments improves safety since it is unlikely that all compartments will be punctured in event of a projectile hitting the balloon. Applying non-stick material to the surfaces of the compartments minimizes aerodynamic drag and prevents adsorption of gas molecules or contaminants on the wall surface which may result in weakening of the balloon structures. Use of helium gas in the outer compartment also avoids gas adsorption and allows natural convection currents for keeping gas circulation within the compartments. The supports are formed of fiber-reinforced or carbon fiber-reinforced polymer or aluminum to enhance strength.
