Wind Turbines are placed atop towers, usually constructed of steel, of varying heights. Due to the immense weight of the Wind Turbine, the Tower holding the Wind Turbine aloft has to be constructed out of a large amount of material to support the Wind Turbine. Otherwise, the Tower could buckle at any point due to the weight above it.
In order to minimize the use of material in the Tower to support the Wind Turbine, the Tower is filled with a Lighter-than-Air Gas, such as Helium, to exert a lifting force against the Wind Turbine at the top of the Tower.
A Lighter-than-Air Gas, such as Helium, is injected into the Tower of a Wind Turbine to exert a force greater than the Earth's surface atmospheric pressure against the base of the Wind Turbine, which is inserted into the top of the Tower as a plug. The compressed Lighter-than-Air Gas exerts an upward pressure against the base of the Wind Turbine, thereby lowering the effective weight of the Wind Turbine on the Tower. This in turn lowers the amount of steel or other material needed to assure the Tower's structural integrity.
