Solar Side Walks by IBM

I have always been fascinated by the amount of things that have been done with the use of solar technology. I have seen a solar powered lawn mower that will cut your grass as well as a solar robot which is in the production phase that acts as a security system.  Well here is yet another amazing invention that is set to be put into play within the next five years. These are extremely thin solar cells that can be placed on sidewalks as well as the walls of your home and even maybe driveways.  IBM stated that they hope to have this set up in the next five years and I think that it would be really cool to see solar panels running alongside the side walk when I walk outside.
