No, no, no. You’re thinking about this wrong. We need to send Stormlight along journeys, not to destinations.
The rest of my post is more serious, I promise.
Also, I think there are already methods to transfer Stormlight from one Gemstone to another, as @Karger said. I think putting these in aluminum pipes like @Oltux72 said would probably keep it super efficient.
In my mind, all we need is a way to cause a “pressure” to make Stormlight flow and aluminum pipes to direct it where we want it to go. The gem transferring method might work as a “pressure,” but there is probably a better way to get “pressure” to make the Stormlight flow.
