Except for such an application, you don't need a "huge" airship.
They don’t say how big the one he’s actually building is.
Being near neutrally bouyant it doesn’t have to devote thrust to generate lift. To loiter it only needs to combat the prevailing wind.
If you wanted to loiter over a metropolitan area for weeks or fly intercontinental you’d need crew quarter for two or three shifts of pilots and technicians. You’d need a massive fuel capacity. The crew might serve like they do on an oil rig, three weeks at a time.
Otherwise, yes the space for radio equipment and powering it is a trivial concern.
If I were Sergey and had money to burn I’d consider this and know everywhere the airship went it would generate hoopla...and eat Verizon and AT&T’s lunch.
