Since several planned devices will consume energy it is probably a good idea to have that available in the block mounted port wiring style as well.

• A Power Hub block (basically a Battery) receives energy through the conventional modded power APIs and the Redstone Control devices can then be hooked up to it.
• Special wires to connect power ports (yellow?).
• In this internal power system, devices will receive an accessor function through their port connections which they can then call to request or push energy from/to the Power Hub.
