Could this idea change the world for the better?

This is definitely a good idea.
 
 The big problem is how the oil and energy conglomerates are going to react to this.  I can see them doing their damndest to drag feet, delay or even halt progress.
 
 Like it mentions in the Video, this would have to start out small (driveways, private roads etc) in order for it to gain momentum and defeat those I mentioned above.

It looks like they address the issue of how it would stand up to being driven on (though how would it stand up to a snow plow?), but the materials would be really, really expensive, so I don't see this going anywhere. Asphalt is used because it's cheap.

edit -- oh yeah, and for it to continue working it would need to be kept clean. Roads generally don't stay clean for long.

Welu:
If this could be done it would be amazing. I like the idea of Tron roads.

Patrick:
I like the idea India has implemented in some places, using solar panels to provide shade for aqueducts. Reduces waste by evaporation by some ridiculously high amount, and the energy produced, while not stellar, is a nice bonus.

This article from 2 years ago details it a bit more.

mustang6172:
How does the coefficient of friction of solar panels compare to asphalt?

Can these be built to accommodate road crown?  If not, how will rain water be directed off the road surface?
