Theory that came to my mind some time ago

This is a way of how this idea of the "house with clean energy" came to me by thinking in a theory. This theory is about systems, there are different types of systems, they might be information systems, chemical systems, biological systems, physical systems, thermodynamic systems, etc... So the theory walk this way, the systems have inputs and outputs, eventually the output of one system might be the input of other system and you might find a way to connect it, then it becomes a larger and a little more complex system, but what is more interesting is that if you have a good menu of systems, knowing their inputs & outputs, some of them might be connected in a way that connecting the systems together they feed each other, and might be that those systems can keep doing whatever they do without need other input from other systems in the environment... I told this theory to my teachers from the univ. they told me that it can't be because they say that close systems doesn't exist, I don't know why they think this is a close systems, it's just systems feeding each other... and actually I don't know what a close system is... well, not knowing what they know make this theory come to me, um... sounds like a proverb or something lol... I just hope the theory can help anyone... love and peace...
