Robert sent some good comments that I am forwarding on to the Stoves 
List Serve.

>> Dear Lanny and all,
>>
>> LANNY STRIKES AGAIN!!!!!!!!!
>>
>> Slick!!!   Simple!!!!!   Congratulations!!!!!!
>>
>> Two main notes:
>>
>> 1.  This layered mass of fuel could probably also be cut into 
>> squares, thereby
>> eliminating the "waste" of the odd shapes outside of the circles.  But
>> there is
>> a certain value of pressing down on the circular cutter and being able
>> to rotate
>> it, helping to make the cut.  Whatever the way it is cut, Lanny's
>> creation of a
>> sawdust-and-newspaper briquette/buscuit is indeed one of the 
>> simplest of ways
>> we have seen for making fuels from readily available waste materials in at
>> least many societies.
>>
>> 2.  A stove already exists that can utilize the "fire biscuits."
>> Without doubt,
>> the T-LUD gasifiers can utilize this uniform biomass fuel.  The fuel
>> units might
>> need to be cut in sizes smaller than the full-sized biscuits, but that is no
>> different than making smaller versions of other "processed" fuels 
>> like Richard
>> Stanley's briquettes or segmenting the dung patties into appropriate 
>> sizes for
>> specific stoves.
>>
>>      As an example, it is quite likely that the "Hanson fire biscuits" could
>> also be produced in long (30 cm ~ 12 inch) "fire rods" or "fire sticks" that
>> could be highly appropriate for use in a Rocket-elbow stove.  (At least
>> that is
>> worth testing to see what thickness/widths will stay together for 
>> that type of
>> stove.
>>
>>     For the T-LUD cookstoves, the biscuit sizes would be nice if about
>> one-inch
>> cubes (about 2x2x2 up to 3x3x3 cm).  No matter that the cubes are not
>> perfect in
>> shape.  When I made some out of dung, they looked a lot like "tablettes".
>>
>> So, Lanny, can you please tell us the inside tricks to do the job like
>> you have
>> done it.
>>
>> A.  What mistakes should we avoid (too much or too little water, etc)?
>>
>> B.How much sawdust, by thickness or by handfulls or how measured?
>>
>> C.  How many varieties (particle sizes, hardwood vs softwood, etc) 
>> of sawdust
>> have you tried, and is there any indication that some are better or 
>> worse than
>> others?
>>
>> D.  What about single sheets of newspaper vs 2 or more sheets between the
>> sawdust layers?  From experience with Richard Stanley's briquettes I 
>> know that
>> 2 or more layers of paper will greatly facilitate the cross-sectional
>> partition/separation of layers in the briquettes.  So, if the stack is
>> 3 inches
>> high and there are double-layers of paper only at the 1 and 3 inch 
>> levels, the
>> biscuits/tablettes could be easily separated into 3 units with each one
>> being 1
>> inch thick.
>>
>> E.  How dry is the optimum material at the time of cutting?  How much
>> drying is
>> needed afterwards?
>>
>> F.  And what about use of any pressure to help push the layers together?
>>
>> G.  And any other observations, please.
>>
>> As soon as I have you reply, I will start making some.  In part I want to
>> compare there with Jeff's fireballs, another of the new technologies to make
>> appropriate fuels from common wastes.
>>
>> With sincere appreciation for your experimentation and imagination about new
>> tricks with old stuff.

>>> Fire Biscuits/Fire Biscuit Cutter
>>>
>>> Dear Stove Friends,
>>>
>>> Check out my new Fire Biscuit Cutter.
>>>
>>> It chops Fire Biscuits out of news paper/junk mail layered with sawdust.
>>>
>>> I am pleased with my new invention and I laughed when after 
>>> chopping down, a
>>> biscuit popped out of the top.
>>>
>>> It is easy to use and there is no grinding, mashing, mixing, loading in, of
>>> the paper just layer the paper and sawdust, soak it for 2-3 days, 
>>> dump it on
>>> plywood, on concrete (to back up impact) an start chopping.
>>>
>>> Now I need a biscuit-burning stove!
