This looks cool, damn that has applications from hell. I wish I came up with stuff like that. Well, more than the general idea of "oh, lets make everything hydrophobic", to the "hm, if we do like this, then maybe we can make anything hydrophobic". Ideas are easy to get, to actually implement and get an idea on how to do it is harder. Maybe if you've spent as much time doing physics and chemistry, as I've spent doing computers, it gets easier... "Turn on the flux capacitor Mr Scott!"
