Give the (deservedly) anonymous author a no-prize for a clearer understanding of low-friction technology than toilet technology. The principal reason toilets have water in them is to prevent odors escaping. Not only is the brown stuff submerged in water during use but, much more importantly, Crapper's celebrated invention is designed so that there is always a water barrier between the user and the main sewer line. Without this barrier, one's home would soon begin to smell like a sewer. The flushing action is designed mainly to carry offensive materials through the barrier. Consider the predecessor of the flush toilet, in which a *very* low coefficient of friction exists between the target material and the transport on the way to the final disposal destination :-). Not something I'd want in my home. Bart Massey [email removed] "Build a better toilet, and the world will stand in line outside your door with legs crossed."
