That’s right. There’s a story on an Italian site (that link is to a translated version) about a new glass making technique involving nanotechnology.
They’ve got a four layer arrangement where each layer performs a different function… shedding water, removing dirt, detecting dirt and powering the whole mess. Thing is it seems to me that this nanotech windshield would be really expensive to make.. wouldn’t a good set of wipers be better?
Of course, I am not a hamster, I know that nanotech can be created in such a way that the end product either assembles itself or is built by a batch of nano-bots. I wonder… what would happen if somebody spilled some of this stuff into the environment? Would the things simply start making glass everywhere?
