Liquid-based cooling solutions used to transfer heat produced by one or more heat generating devices from one or more electronics servers to the ambient. The balls contain tungsten or another high density filler in a solid, central core in order to enhance coefficient of restitution, and have very high quantities of whitening agent in the outer cover layer to increase the moment of inertia and thus reduce spin. The controller receives information related to a condition of the process over a first communication network, determines a control signal based on the received information and the programmed process, and sends the control signal over a second communication network to a benchtop utility tower. At least one sidewall is angled less than approximately 85 degrees from the plane of the top surface of the substrate.
