Hello Alex.....

     So I guess maybe I am interested in learning about how char is made now and just maybe I might think of ways to make it with less environmental down sides. Any further info would be great, Thanks for your time.

    Roger,

    There are indeed many reasons not to make char. However char is very
    different from ash. In fact some say it is unique and there is no
    synthetic equivalent. Two of it's special properties that are well
    understood and desirable are its ability to absorb/adsorb and that
    it is resistant to microbial decay.  This is why people want to
    explore ways of making it. It can vary widely in its properties
    based on how it is made and what it is made out of.  If it truely
    has value then it changes the equations associated with bioenergy.
    Its not just about energy its about utility. We currently produce
    many products from biomass and often extract energy from what is
    left. Char is just another possible product, one with some
    potentially significant environmental benefits.

        Hello all,

        

                 It is in my limited understanding that "bio char" gives
        a home to microbial organisms which in turn bring much needed
        "natural fertilizers" to ones garden, is this true? From the
        reading I have done I can not think of any way of creating the
        char without sustaining other losses, many of which can be seen
        in pictures of destructive practices, slash burns, air
        pollution, and the ridiculous end cost of the process on our
        environment. 

                 From the text below I have the gut response of the
        following analogy. The race car driver and the Granny. Mario
        Andretti rapidly goes from the gas pedal to the brake pedal and
        back to get every ounce of performance he can from his
        machine.....screw economy. The Granny acts as if there is an egg
        shell between her foot and the pedal which she wants to keep
        safe at all cost. Who gets the best fuel economy.......surely
        not Mario. In this thinking I bring up the "Russian fireplace",
        The oldest and most widely used High Mass heater I have known in
        my 26 years. They are typically loaded up with 80 lbs of fuel
        and burned off one or two times per day. Thats up to 160 pounds
        every 24 hours, and no char is left. I believe that the common
        EPA certified wood stove can provide just as much "useable" heat
        to ones home with allot less fuel, and no char is left. 

                So, I am asking out loud.......are we better off
        selecting the heat source that gets more for our waning
        resources, and maybe asking if there is another medium for
        giving a home to these microbial critters other than just the
        "char". What is it about the char that is beneficial? Does the
        ash from the fire also allow for the "housing" process?  Can we
        learn to utilize this process in a way that does not cost mother
        earth an arm and a leg? If this process really works as well as
        proponents claim, then there must also be an ecologically
        intelligent way to create a medium for housing these life giving
        microbes.

        

                        Comments?

        

                          Roger.
