Swarms Of Tiny Robots To Monitor Water Pollution
savi writes "The University of Southern California School of Engineering has received a research grant to create swarms of microscopic robots to monitor potentially dangerous microorganisms in the ocean. Basically, nanoscale robots with electrical and mechanical components that can propel themselves, send signals, and do basic computations. "
Will the nanoprobes monitor the water supply for pollution by nanoprobes? Huh? Huh?
Napster-to-go says "Fill and refill your compatible MP3 player", which is a lie. It's not MP3. It's WMA with DRM.
BTW, read in the Sunday paper that Erin Brockovich is on the trail of another suit against PG&E for Chromium 6 in ground water.
Interested in a history of water use and mis-use? Read Cadillac Desert, by Marc Reisner.

Now for those of us that read the Damn article. The ability for the project to suceed on only 1.5 mil is pretty ambitious, the article mentions that they need the software to link together millions of these 'bots via weak radio link, and a mass producing method of creating the other 999,990 units. I would really like to know how they fit a device that transmits a unique indenitifer and a binary digit in an envirment that would seem to distort any type of transmission and amplify electric interfernece.

I'm not that big on the mechanical nanotech, we have a long way yet to go before we can duplicate some of the most perfect nanotech systems out there: microorganisms.
We have the ability right now to craft custom virii and bacteria which can replicate and destroy other creatures. If we want to kill cryptosporidium and giardia (two common water-bourne parasites) then we should find the natural predators of such creatures and turn them to our needs.
It's similar to the chemical spraying of crops to prevent insects and other pests from destroying harvests. For years we have been laying on the pesticides in order to stop crops from being ruined. Instead of relying on chemicals, we should instead be investing in natural methods of reducing pests, such as the use of preying mantis, ladybugs, egg-laying wasps, and other natural predators.
Don't get me wrong, I don't think that all chemicals are evil and should be eliminated. I'm a chemist myself. I do believe that we can be much more effective if we cut back on the more toxic chemicals and replace them with more gentle alternatives. Many of the harsher chemicals build up and end up destroying the producing potential of our farmlands.
Sapere aude!
