So a tiny nanotechnology that doesn't require any external power besides the sun to kill all life in large quantities of water.

I'd like to see some science fiction endings for this.


Direct sunlight kills a lot of things pretty well on its own. A lot of multicellular organisms that spend much time in the sun have all sorts of adaptations to deal with it.


But this doesn't kill them with direct sunlight, it just uses direct sunlight, so those organisms are still susceptible.

My point about "sunlight" was simply that it doesn't need to be otherwise powered, I wasn't talking about the killing mechanism.


I think we're obliged at this point to bring up the cancer concerns that are always present when dealing with nano-scale particles. Can these nanoflakes break off? I know the asbestos problems were when breathed in, are there also problems with drinking them? A very interesting product, though.


Cool! Embed that in my water bottle bottom please.
