. . ."solar cells can be inexpensively printed or simply painted on 
exterior building walls and/or roof top"
. . .
"The solar cell developed at NJIT uses carbon nanotubes 50,000 times 
smaller than a human hair."

Given our increasing need to collect drinking water from rooftops, I 
don't know how wise it would be to paint the roof with a finish 
containing nanoparticles.  Apart from that: interesting technology.
