I'm actually far less alarmed about the material. It sounds pretty great. What worries me is this fixation we seem to have with eliminating bacteria... Isn't there a downside to this? If we spread it around as much as this article describes it seems to me like we'd greatly sanitize our environment... What happens if we greatly reduce the amount of bacteria we're exposed to daily due to some sort of invention like nan…
First bacteria that figures out how to stick to this will have nice place to live and develop, plenty of human associated food and no competition.

Concerns of breathing in this silicate have been popping up a lot in this discussion (especially concerns about silicosis). I’d just like to point out that we’re discussing very small quantities; nano-coatings of ~100nm, only 15-30 molecules high as mentioned in the articles. Wikipedia states that the silicate clusters ascribed to silicosis each have a diameter of ~10 microns; each clusters is 100 times larger than t…

In dealing with the sick and in preparing food come to mind.
I wouldn't mind it for electronics either.
This seems like the kind of report they'd show as a flashback in a post-apocalyptic film :)
I'm going to start a pool. Buy in is $200 equivalent[1] per square. The board will be a 3 dimensional matrix, whose axis are: 1. The amount of time from now the collapse occurs. (most likely a logrithmic scale) 2. How far civilization falls, e.g. "back to the 19th century" or "back to the stone age"[2]. 3. How "wierd" this makes the world, e.g. are there 40 degree temperature shifts in the afternoon in San Diego and…

Remember when Dean Kamen claimed that the Segway would change the way we built cities? Most hilarious product launch ever.
Talk about overpromising and underdelivering. I remember people speculating that he'd designed a compact, powerful hydrogen fuel cell, hoverboard or something similar.

Silica is one of the most abundant oxides in the earths crust. Our bodies have no problem dealing with it.
I have one word for you, but it's a doozy: pneumoultramicroscopicsilicovolcanoconiosis.

It still is, so long as it's sequestered such that the fibers don't become airborne. Asbestos removal projects done in eg. municipal buildings are often misguided.
Try " usually misguided". Several reports have come out that airborne asbestos is usually worse after asbestos removal than before. Going over it with a sprayed on sealer would be safer and more effective.
Like liquid glass?

Like either of those would be massively revolutionary either.
The coating is environmentally harmless and non-toxic, and easy to clean using only water or a simple wipe with a damp cloth. It repels bacteria, water and dirt, and resists heat, UV light and even acids. How can you use water to clean it if it repels water?
How do you wash your teflon pans?
