There's no citation for that, so it could be what WP calls "original research". It is, however, pretty likely the right OOM. That would put the storage capacity at around 1000x, and, if the estimates of the cranes' gener

I would expect a signficant limiting factor to be the cost of dam construction (which is going to go up at least geometrically with height, assuming a V-shaped opening), not the height of the already-constructed-by-nature surrounding walls.

I was thinking the airports in question would be large ones for connecting flights. I would be very surprised if one were ever stuck at such a small one for 12 hours. Presumably one would just return to town and be stuck there, instead.

I'm confident that situation is far from unusual, and it's my theory as to why AWS is so wildly succussful. For all the lip service given to "you have to do a cost comparison", it doesn't happen in practice.
