Thanks for posting. This cluster of O'Neill cylinders seems to lack a means of heat disposal. If the cluster were larger (more cylinders), that would seems to become more of a problem. It might make more sense to arrange them in a 2-dimensional array with one side for solar-collection, and the other side for heat disposal. That way they could be placed very close together (to facilitate inter-cylinder transportation) without blocking light-access or cosmic-background-view.
