Comments on: Towards frictionless nanomachines http://www.foresight.org/nanodot/?p=2280 examining transformative technology Wed, 03 Apr 2013 18:23:47 +0000 hourly 1 http://wordpress.org/?v=3.0.4 By: Eric T. http://www.foresight.org/nanodot/?p=2280#comment-25068 Eric T.

I'm also interested to know to what level of the nanoscale the author/researchers are referring--if you're dealing with a machine composed of just a few molecules, friction will affect it in a different way from a machine made of hundreds or thousands of molecules. Of course, function and mode of operation/activation of the machine play a huge part in the process too. To borrow another idea proposed by one or more of the innovators in this field, what about acoustic control/activation? (also addressed by Dr. Merkle in the abovementioned article) I'm even less of an expert, so I may be shooting in the dark here...

Once you have atomically precise molecular machine parts, and inert gas and/or high vacuum chambers for these to operate in, then the problems associated with current enviroments are no longer a problem, ie, such as "How will these gears work in water?"
