Earlier this year, a team of scientists demonstrated a tiny boat that uses surface tension, but no moving parts to navigate through water (see http://www.pitt.edu/news2009/Cho.pdf" ).
I wonder if a boat with hydrophilic material at the back and hydrophobic material at the front can propel itself in the same manner. If not, why? If so, does that mean a perpetual motion machine can be made using a circular trough and one such boat?
