[Terrapreta] pulverizing charcoal

[Sean K. Barry]

Hi Roy,

Why?  I think that a cement mixer that uses more power, to emit more CO2, than could be sequestered is a pretty f**ked up cement mixer.  That's really, really bad super low (ass backwards) energy efficiency or you do you expect to make a cup full of charcoal by running it for a month.  Your previous idea (was it yours?) to use water power to turn a drum and tumble rocks in with lumpy charcoal until it is fined grained isn't a bad idea at all.  But, it is basically not so different than using a cement mixer to do the same thing.  What about guys who don't have streams running through their backyard?!

Regards,

SKB

  What does the cement mixer run on? There are many ways to do this by using petroleum. Of course, those ways release more carbon to the atmosphere than the char preserves in the soil. In the pulverizing party idea, realistically many of the people present will be fueled by petroleum based foods so, as amusing as it may be, it's not really that good an idea.

    Why not toss the char in a cement mixer with some rocks?

      I have to try as I'm supposed to be an idea type person.  Get a good sized piece of the heavy plasic sheeting used to line land fills and such. Decide where to hold a pulverizing party. Lay out the sheeting on the floor and cover it with the lumpy charcoal. Fold the rest of the sheeting on top and clamp the edges, This will have the same sort of attraction as do the plastic bubbles in that wrapping sheeting. Everyone loves to pop them! Everyone one will love to search out and crunch the charcoal lumps. Hold regular charcoal crunching parties or dances. The kids will love it!
