Ok, I was looking over the older forums (again) and came across one of the ideas for increaseing the battery, it was one of the more joked about ideas than serious, but it was useing solar cells to charge the battery... what if you were to put solar cells on the top of the case, connect them to the battery, and put some kind of hard drying clear coat to protect the cells... that way your comp would look cool, be an offical mod, and charge your battery all in one... (current thought for taking power, is routing it through the screen power relay... i have no idea if this would work... and i am unable to try because of my applecare warenty is still on... and i dont really want to lose a year of it...)
