These devices were discovered by archeologists. They estimated their date of creation to have been somewhere between 250 B.C. to A.D. 500. There is enough of them in The Great Movement Chamber to keep Castle Heterodyne active and semi-alert from the time it was attacked by The Other until just before the Siege of Mechanicsburg by Klaus Wulfenbach and a great many other plotters and Sparks. Faustus Heterodyne either rediscovered how to make them or had somehow learneed about them because he equipped Castle Heterodyne with them as a backup power system.
