 - [?] What are Stirling Engines? #MARVEL 
+Stirling engines are

+Anyways, MARVEL also uses an interesting drum based system to do power control.
+They use one big central 'insurance' rod, but also have four drums around the cylindrical 
+core. These drums have a poison side, whose angle of incidence on the reactor plays a large part in how much neutron fission is allowed to happen. These drums have a fail-close state, that if something
+were to happen to the controller, they would passively return to a shut position. To keep the poison
+faces from killing with the reactor, the controller must actively apply force to the drums to prevent 
+them rotating. 
+
+These drum based control systems have a significant advantage that they don't create a 
+longitudinal imbalance in reaction rate, compared to a typical control rod. Since they face / shy from
+the entire core equally along its length, they can probably be more efficiient, and take up way less 
+space. The insurance rod is a typical rod however, as it would not be possible to put a rotating
+control drum in the middle of a cylinder. 🤷‍♂️
