Considered as an artistic medium, airwaves are not neutral, nor are they immaterial. The decision to broadcast is linked to the decision to activate electronic circuits. Radio holds both propagandistic and subversive potentials. But even the most experimental broad- or webcasts rely on electronic or digital technologies. Thus, responsible radio productions cannot shy away from a self-critical, and political positioning in this regard. What political implications does it have for radio art that transmission rests on a system of energy-consuming technologies? This question calls for a theorization that nuances the idea of podcasting as an ephemeral and intimate medium. This article proposes the term weightless infrastructures in rethinking satellites as atmospheric, free-floating and free-falling technological infrastructures. This notion is abbreviated and used interchangeably with the following terms: weightless technology, weightless hardware and free-floating infrastructure.

作为一种艺术媒介，电波不是中立的，也不是非物质的。广播的决定与激活电子电路的决定相关。广播具有宣传和颠覆的潜力。但即使是最具实验性的广播或网络广播也依赖于电子或数字技术。因此，负责任的广播制作不能回避在这方面的自我批评和政治定位。广播艺术的传输依赖于能源消耗技术系统，这对广播艺术有什么政治影响？这个问题需要一种理论来细致化播客作为一种短暂而亲密的媒介的理念。本文提出了“失重基础设施”一词，将卫星重新视为大气、自由漂浮和自由落体的技术基础设施。这个概念被缩写并与以下术语互换使用：失重技术、失重硬件和自由浮动基础设施。
