I do not think solar cells would even provide a drop in the bucket compared to the energy (hard 'g') demands of any worthwhile robot. However, I might be greatly underestimating the area occupied by skin; I am aware the the skin is the largest of all organs (except on
living Skeletons such as the ones in the old fantasy Ray Harryhausen films about Jason & the Argonauts, etc!). But if I wanted a child-sized robot, I would want one soft, warm, & cuddly, rather than cold and hard.
True, it might be cool to have
GORT as a friend, just think of the advantages:
- you would never lack for a vacant parking space
- You would never need to wait in line or in the queue, people would be happy to give you 'frontsies.'
- No matter your age, they would always give you the senior discount!
Just try that with a cute little "child-alike robot!" :d evil:
