[Terrapreta] National Biomass Producers Association Demenstrationof Thermochemical Biochar

[Greg and April]

That's not what I'm getting from the article.

The way I understand it they are just making a trailer demonstration unit to show it can be done - no word as to the amount of fuel return, let alone enough that would fuel a farm ( big or small ) or what such a unit would cost.

Would be fairly dumb and useless if it requires a large farm income to make, large farm cellulose output but only returned a small farm fuel supply.

I would be more interested in finding out if it was adaptable to produce butanol instead of ethanol.

  I thought that cellulosic ethanol was just in its early stages of development?  But these people already have a working portable model for farm use??

    I'm still not fond of ethanol and think that while it may be a fair short term solution, I believe that it will be a dead end fuel - I think that butanol is going to be the long term solution.

      NBPA to demonstrate cellulosic ethanol production
      From the March 2008 Issue


      "The thermochemical process also produces a byproduct called biochar, which serves as a viable soil amendment with important fertilizer properties that could offset farmers' high fertilizer costs. Due to the mobility of on-site production, logistical issues associated with feedstock collection and transportation would also be eliminated. "It's what's going to work best for everyone involved, including the wildlife," Cahoj said. "It brings a lot of variables into the picture that people need to be thinking about, and the time to act is now."
