A direct-to-machine Nespresso delivery system
Coffee capsules could flow like a public utility, and we don't have to deploy pipes under the streets.
A delivery person inserts a battery of coffee capsules. They are then transported to the capsule queue using air pressure. With this, there's always a capsule ready to brew in the machine. After use, the capsule is transported to a trash container on the ground level, using nothing but gravity.
