Concept Time - VisCOM

For my first concept i'm thinking of making a battery powered leg , where a large car like battery replaces the calve muscles , it may be too similar to the million dollar man or even iron man?
So i'm thinking more or a hybrid that gets slotted into the leg, where the top of the piece is the positive end of a common double A lithium battery. The base will look like a normal leg , toes, foot, ankle, shin, calve, hair, etc ... between the leg base and the battery head i am thinking of having a preferated edge, or even a srewed edge, like the end of a lightbulb or the top of a bottle.

i don't want my pice to look like this but it's hilarious and makes me laugh so i'll aspire to make something this amzing ... someday !!!

i may even resort to a more machine like version but i'll see how the concept works first :)

I also am thinking of making a personal twist on the CFL bulb with a replaced top on the piece... the replacement will have to be an item you replace everyday, like toiletries or a pencil :)
