NanoMarkets believes that there are, however, indications that self-cleaning windows have a bright future. The trends that impress us here are mostly technological in nature, but this shouldn't be taken to mean that they are restricted in some sense to what is going on in an industrial lab.

On the contrary, what we are seeing are signs that there is a growing technological impetus behind self-cleaning windows that will enable them to meet their "obvious" market potential.  NanoMarkets believes that these newer technologies—and riffs on older technologies—will (1) improve the performance standards for self-cleaning windows and (2) make such windows more affordable.
