Yeah, I read about thermal depolymerization (sp?). It sounds really interesting, but the company behind it is being very secretive with regard to particulars on things like energy balance and production costs. I know there is a Butterball turkey plant in Missouri operating an experimental thermal depolymerization plant right now where they are turning waste material from the turkey processing plant into some kind of oil that can be used in place of diesel, but there is no information out as to how well it's working, how much it costs to do it, how much energy it's taking, how much negative impact it has on the environment, or anything like that. When you look at Changing World Technologies website everything they say is rosy and positive, sounding almost too good to be true, but real details are seriously lacking. It may be that they have viable technology that will help us fulfill a major portion of our fuel needs with fuel made from waste material, or it may be that what they have is technology that isn't environmentally sound and that will never be cost effective enough. They have a really interesting concept, but there just isn't enough known about it to know if it's going to amount to anything of great importance with respect to our energy concerns. We'll just have to wait and see.
