These mechanisms would require huge amounts of electricity, which could be provided by solar panels or potentially even nuclear systems. Current designs estimate that it would take about 8 days to elevate an object into geostationary orbit.
这些机制需要大量电力,这些电力可以由太阳能电池板甚至核系统提供。目前设计估计,将物体提升到地球静止轨道大约需要 8 天。
