Electricity in Zion
This might be brought up before, so forgive me if it's old...
This came to me last night that Zion appeared to be fully powered by some serious generators! Look at all the complex lighting and computer systems, not to mention charging up all the hovercraft. Now, the idea is, where the heck does human gets all these powers?
The answer is easy: theraml energy from the core of the earth. Now this begs another question: if the humans can use it, why can't the machines?
This makes me wonder that machines do NOT need humans to be their batteries at all. Please, why should machines stay on the surface? For the scenery?
Now, if the Matrix isn't created for energy purpose alone (which, can still be some sort of recycling for bio-energy in humans), what is it for?
Maybe it's created to better understand human psyche, and in the same time, screening for the One, who would be able to unite humans and machines. (According to the Oracle, humans and machines need each other to create the future. The theme of Second Renaissance in Animatrix also shows that killing each other only makes lives miserable.)
Of course, this is just some guesses. The creators have this one "right" answer to it, but it's just neat for fans to make all sorts of interesting guesses. Let me know what you think.
