Power Generation?

OK im making a space station type game. For this i need to be able to set up a power grid along with life support.

I was wondering how to go about setting power generation up for starters? I havent the foggyest idea on where to begin.

You might want to start by creating monobehaviours like "PowerNode" or "GeneratingStation" that include arrays of the the other PowerNodes they're connected to, and a method for connecting two Nodes.

take a look in the AuotWayPoint scripts on the FPS tutorial : http://unity3d.com/support/old-resources/tutorials/fpstutorial

it should give you some pointers on how to do the power interaction.
