Warning, extreme science ahead, if you do not understand whats being explained here don't feel bad, because I don't understand it either! Ok now seriously, the scientific explanations I have come up with are as scientific as I could make them, but I had to delve into science fiction to tie it all together. If you see something that is drastically scientifically inaccurate, SAY SO in the comments. This is how I see the supercomputer and its components working, if you have a better more logical explanation shoot it off in the comments, destroy the work I did here! I want you to pick it apart!

Jeremy's Technical Notes: Supercomputer Power source

The supercomputer can be independently run off of the power grid by utilizing the radiation and decaying particles of Lead isotopes. The lead fuel rod is contained within the bottom core of the main supercomputer processing unit. The Lead rod can power the supercomputer for roughly 15 or 20 years depending on how much power is required and how many return to the pasts the Lead isotopes must endure. A return to the past disrupts the molecular state of the Lead because it is radioactive and is contained near the epicenter of the return to the past phenomenon. The radioactive beta and alpha particles emitted by the lead isotope is directly absorbed into the Supercomputers systems as almost pure energy. There are no nuclear or fusion reactors contained within the Lyoko supercomputer. If the supercomputer Lead isotope power source does however fail the Supercomputer could theoretically be adapted to run off of a commercial power grid. The power consumption rate would however be enormous, in a single minute the supercomputer would absorb as much energy as a common town house will consume in a month.

Aelita's translation- The lead fuel rod in the supercomputer acts like a big battery. There is no nuclear reaction in the supercomputer, so no chance of nuclear explosions. The lead fuel rod can last for 15 or 20years until it needs to be replaced.

Goody, that was fun but we already know quite a bit about the supercomputer power source, their was an entire episode devoted to it. My next loge entry will be far more interesting. The scanners.
