[Terrapreta] carbon sequestration but where is TP?

If I could be so bold as to offer a few reasons;
   
  As I and others have pointed out, the LifeCycle analysis of most char systems doesnt seem to offer any real advantage overall. 
   
  Additionally, TP is a relatively new science and as the banter on this site shows, is still pretty thin in real data. Example is show me a study where we can see the charcoal we make now will remain charcoal in the soil for 100 + years... ?  
   
  Lastly and likely most importantly, there are no major corp's pushing char because they dont see economic models in a distributive productionlike char in the fields would likely be. Its much easier to think how someone is going to make $ on a $200m project injecting CO2 into a well from a coal plant than a whole bunch of farmers making charcoal out of stumps and corn cobs... and unfortunately $ talks. 
   
  On a bright note...I do see this worm starting to turn, the word is getting out. The more data we have (ground truth), the louder the voice becomes. Also, the economy of CO2 is still in its infancy, its still to fully mature. 
   
  The group needs to remember that even tho the technology is 1000's of years old, we are all still early adopters.

  I searched through the UNFCCC’s 2001 and 2007 IPCC reports on mitigation and found no mention of Terra Preta or char. They come close in the 2007 report by talking about burning biomass for energy, and capturing and sequestering the carbon dioxide. It’s not too much of a leap of imagination to go to the concept of partial combustion with the production of char – but it seems to be taking a long time. A cynic might think the UN and the IPCC are not interested in techniques that might work - and also produce side benefits which might be more important than their original goal to manage atmospheric carbon dioxide.
