Well, according to the article (http://www.discover.com/may_03/featoil.html) 
 they don't burn anything, it's more akin to boiling.  This is what makes 
it possible to break down PVC plastics and other such materials.  As to the 
energy it takes, to quote the article  "Thermal depolymerization, Appel 
says, has proved to be 85 percent energy efficient for complex feedstocks, 
such as turkey offal: "That means for every 100 Btus in the feedstock, we 
use only 15 Btus to run the process." He contends the efficiency is even 
better for relatively dry raw materials, such as plastics."

Right on about traffic jams however.  Probably no getting rid of that until 
we create instant teleportation.  :-)
