I want magic windows for my dream house

I've been watching and reading a lot of ecology/organic friendly technology reviews. One of the best has to be the window that never needs washing. It's based on the lotus leaf, which has an irregular surface that repels water. Treehugger did a review of a paint using the same technology.

But if you combined the lotus leaf surface with a solar panel? That would be really the best of all worlds. The solar cells could even power your Christmas lights, if you used LEDs.

BBC World ran an episode called Bionic Buildings, exploring new applications of biomimicry in architecture. One of the ideas was auto-controlled blinds on glass buildings, to control passive solar gain. Why not have the blinds powered by the solar powered gathered from the window?

So, a magic window: no washing, no closing the blinds, a solar panel, a stained glass design if you like, an option for LED Christmas lights, and.... what about one-way glass at night? Or would that be asking too much?
