The Propulsion Lab is where we assemble Comets and Planetoids into Drives. My research into human culture has revealed that a “song demo” may be a more familiar term for Explorers here from Earth. These are roughly formed musical ideas that can be shared with interested parties.
Fueled by Comets and Planetoids, Drives are used to power Ships.
Explorers with sufficient Creative Energy Units may access individual Drives for enjoyment, investment, and collaboration.
