Orichalcum Flywheel

This highly advanced energy storage device combines a frictionless vaccum tube with the time-warping properties of orichalcum to hold kinetic energy. These finicky batteries only operate safely within narrow circumstances but cunning engineers and artifactors have effectively utilized them to revolutionize industry within Granmont. Most notably they're the keystone component of Riverboats, but they've also been applied to Golemlore and mining.
