If economical it would be great for a driveway or patio that is in the sun. My driveway is not shaded by cars 99% of the time.
There is a "smart-floor" concept but it is very expensive. I am not sure if it incorporates solar power generation.
I remember seeing an article where lighted programable road-markings could be incorporated into a "smart-road" that was solar-powered too.
Thanks for your comment!
Steem on,
