:excited: Me and my friend have come up with a theory about ki energy. Here goes:
One's ki energy may be obtained by harnessing each of your cells' mitochondria energy output, therefore being able to produce products of energy (i.e. kamehameha waves, finger beams, etc.) depending on concentration of energy and one's own tolerance. Now the saiyajin race is capable of higher concentrations of energy and tolerance upon their bodies due to a life under high gravitational pressure on their planet. Humans however have a sort of energy "plateu", which is the brink of spontaneous human combustion. To explain, under increasing pressure levels, combustion of molecules becomes more difficult (Water boils at lower temperatures in the mountains compared to sea level due to less atmospheric pressure.).
This is just a raw explanation, so additional information is welcome. Just email me if anyone is interested about it or wants to disscuss it.
Parasite Eve projects that mitochondria are individual organisms rebelling against their parasitic human bodies that leech their power and energy.
Those interested in a Ki martial arts go to [url]http://ki-aikido.net/[/url] and look for a dojo near you.
And another thing, just about ALL anime talks of Ki use, and it is misrepresented in DB series as a sort of blast 'em away power, for it is taught to be used in healing and avoiding attacks by 'deflecting' a would-be attack.
