thermal depolymerization machine

have you ever herd of this?
aparently it can turn organic matter into oil
how cool is this ?
more info can be found all over the place
http://en.wikipedia.org/wiki/Thermal_depolymerization

from that web site.

"Previous methods to create hydrocarbons from depolymerization expend a lot of energy to remove water from the materials. This hydrous pyrolysis method instead uses water to improve the heating process and contribute hydrogen from water to the reactions.

The feedstock material is first ground into small chunks, and mixed with water if it is especially dry. It is then fed into a reaction chamber where it is heated to around 250 °C and subjected to 600 lbf/in² (4 MPa) for approximately 15 minutes, after which the pressure is rapidly released to boil off most of the water. The result is a mix of crude hydrocarbons and solid minerals, which are separated out. The hydrocarbons are sent to a second-stage reactor where they are heated to 500 °C, further breaking down the longer chains, and the resulting mix of hydrocarbons is then distilled in a manner similar to conventional oil refining.

Working with turkey offal as the feedstock, the process proved to have yield efficiencies of approximately 85%; in other words, the energy required to process materials could be supplied by using 15% of the petroleum output. Alternatively, one could consider the energy efficiency of the process to be 560% (85 units of energy produced for 15 units of energy consumed). The company claims that 15 to 20% of feedstock energy is used to provide energy for the plant. The remaining energy is available in the converted product. Higher efficiencies may be possible with drier and more carbon-rich feedstocks, such as waste plastic."


I just thought it is a really cool thing, I knew it was possible, I just did not know that people were using them as much as they are.
