How will the studio receive power? Is it just hooked up to the power grid or does it have a solar farm?
I'm sure they'll say that Jehovah will see to it that the worlds power grid and satellites are left intact and that his Holy Spirit will enable our clever brothers and sisters from around the world to keep them operating.
At the same time, they'll ignore the fact that all the studios and printing facilities of the world could also be left intact and at their disposal and they don't need to build this new one. Not to mention the likelihood that all the TV and radio stations could also be left intact and they can broadcast JW info all day every day.
