The taxi and car-rental businesses might merge into one automated pick-up and drop-off service : gm has already shown a prototype of a two-seater , battery-powered pod that would scuttle about town , with passengers summoning it by smartphone .
Each pod will be able to hold four guests and two astronaut-pilots .
每个吊舱将可以容纳4个游客外加2个宇航员。
Typical assignment : design a lunar pod to support four nasa astronauts on a 28-day stint
典型的任务:设计一个月球吊舱以维持4个美国航天局宇航员进站28天
But the rolls-royce azipull has the propeller at the front of the pod rather than the back .
但是劳斯莱斯azipull是在前方有螺旋桨荚而不是后面。
The space hotel , which popsci covered when it was first announced in 2007 , would start out as a single pod capable of holding four guests and two pilots .
