<p>An object is supported freely in space without requiring an anchoring point connected to ground, by attaching the object to a support structure adapted to float in air when filed with a gas having lower specific gravity than air at a controlled pressure that provides sufficient buoyancy for different weight objects. The support structure is released together with the attached object so as to reach an equilibrium position where a buoyancy force of the support structure counteracts a combined weight of the enclosure and attached object. The object may be integral with the support structure and may be a self-powered electrical device operating on a battery or solar energy. The enclosure may be a floating platform or may be part of an object.</p> |
