I believe he suggest to establish a chain of smoke signal towers transmitting the bits of our holiday photos to our distant relatives. During the day and when there is no wind of course.

There is no alterntive between storing everything in the cloud and smoke towers.

(still, I assume not the cloud storage is the most energy intensive thingy out there - but perhaps the processing of those for whatever agenda, and else - but the w3 signals are mixed the least. Perhaps this is from some sort of common corporate script book distributed in the MBI courses, from the chapter "how to pretend being serious environmentalist", mixed with the other one "deflect inconvenient/expensive steps into the infinite future or never by forming an interest group")

Probably suggesting that cloud storage and cloud server products use energy less efficiently than a more simple setup
