Mold/algae will grow on the wet surfaces in a matter of days, destroying the main promise of the material.

  Im not so sure. Mildew has to eat something. Assuming the surface is kept clean and water is collected regularly, it shouldn't be a major problem. You don't see mildew growing on cars very often, do you? Yet, growing up in Florida, I'd see few covered cars in the morning all the time.

    Cars not, they go to wash. Those who don't are indeed visibly dusty/moldy. Wet roofs and other surfaces -- pretty much all the time, especially in humid climates (like Hong Kong, where the research is made). Same for glass windows (we have window-washer job for that reason). Surfaces can be cleaned with pressure washer, but unlike purely aesthetical reasons, I'm saying that the main feature of this material may stop working in a matter of days due to even minuscule amount of growth.
