Nanotech Gone Awry? 173
westcoaster004 writes "Chemical and Engineering News is reporting what appears to be 'the first recall of a nanotechnology-based product' due to health risks associated with it. The recall of 'Magic Nano' spray, which is for use on glass and ceramic surfaces to make them repel dirt and water, comes after at least 77 people in Germany contacted regional poison control centers after experiencing illness after using the product. The German Federal Institute for Risk Assessment has also issued a warning." Relatedly dolphin558 writes "There is an interesting story in the Washington Post on the unknown dangers facing employees of nanotechnology firms. The jury is still out on whether traditional HAZMAT safeguards are suitable when handling nanomaterials, many of which can be harmful. Research into potential workplace hazards is beginning to ramp up as the industry and government become more aware of this issue."

We already have nanomachines that replicate themselves every 1000 seconds or less (that's a doubling time of roughly 17 minutes). They're called bacteria. We use them to treat sewage, alter milk into cheese, and produce synthetic insulin feedstock, along with several thousand other uses. Some of these applications have been in existence for most of recorded history. Startlingly, the Earth has not been converted into bacteria.
The Grey Goo argument is an interesting layman's theory that falls apart if you give it any real thought. You cannot build a self-replicating machine out of simply anything. The machine will rely on critical "nutrients", whether they are nitrogen, phosphorous, or copper, that simply aren't available in large quantities in much of the environment. The machine will also require a readily available energy source, which ultimately means solar power since life does a reasonable job of exhausting chemical based energy sources on the surface of the planet.
Face it, evolution favors favors fast replication, efficient resource utilization, and wide geographic distribution. In four billion years, using technology that we can just barely duplicate (mostly by scavenging parts from nature), evolution has created -- TADA! -- algae and pseudomonas (for example). The last time I checked, these self replicating micromachines weren't threatening to turn my house into more algae and pseudomonas at any significant rate.
Grey goo is a nice science fiction story, but frankly it's never going to happen. If you want to fear deadly self-replicating nanomachines bringing an end to civilization, then you need to focus on infectious diseases (mostly viruses) like the rest of the highly educated public.

Why would we want to set that kind of situation up? Oh, right. Because it makes monsanto rich, and secondarily makes congressmen rich. Gotcha.
