I have been watching Nanosolar.com for a few years now. What is your estimate of time before we have commercially available nanosolar?

What hazards of current nanotechnology are the most applicable to the ordinary citizen. In other words, what should we be ready to avoid.

What are the potential benefits in the medical field, ie. cancer, cardiac, diabetes, etc

We know that nanosizing particles changes their physical characteristics. What do we know about the combinations of nanoparticles. While there be reactions which lead us in new tangents?

What do we know of foreign research. The axis of evil and potential threats which nano particles could make more potent.

Does nano exist in chrystal materials.

Thank you.
