The big bad enemy in efficiency is friction. It prevents us from creating perpetual motion, it gives us Indian burns, and it makes certain kinds of adult activities hurt(im sorry honey). One of these daily battles takes place under the hood of your car, the oil you put in there help relieve the friction of the 48 different moving parts to your engine (unless you have a rotary engine in which its 3). Dr. Guojun Liu, a Chemistry professor at Queen’s University, added micro sized polymers to oil and it had a drastic effect in friction, namely it cut the negative effects in half. Boy those polymers are pretty good huh? This isn’t just limited to engines either, it can be used in any number of rough contact applications(machinery not football). Lets hope we can get some of this soon, for the car not the bedroom.
