<DIV><FONT size=2 face=Arial>A well placed sparker in a TLUD could re-ignite the
flame if it is extinguished by a wind gust or stove mis-managment. This
could save the house from being filled with smoke, especially if the
spark is automatic. Could such a sparker also be used to
start a new fire, thus getting two uses from one device?
How have stove fires been started before? The people using the
stoves have been starting cooking fires all their lives, and
they must already know what works for them.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I did some experiments for backpacking with good
results. Wax impregnated corrigated cardboard found at the local grocery
store as lettuce boxes, can be torn to seperate the
layers. The torn surface has lots of small hairs which
ignite easily with a flint and steel spark, match or bic lighter. Because
of the wax, a fairly small piece burns long enough to start some
kindling. This is free starter material where
available. Stoves could be shipped in waxed boxes or recycled lettuce
boxes to provide some starter material. Though this might increase
costs, one box could last perhaps a year since so little is needed for one
fire. Could a piece of torn waxed cardboard be ignited by placing it
in contact with the above mentioned sparker, and once ignited placed
below some kindling to start a new fire? Sprinkle a little shaved
magnesium on it (or on other flamable material), and it can be ignited
very easily by focusing sun light on it with a magnifying lense.</FONT></DIV>

<DIV><FONT size=2 face=Arial>I have asked for and received permission to
demonstrate the 5 new TLUD turn-down methods at Aprovecho stove camp this
summer. It will be an aside from the main program, at a not to
busy time. I will also introduce an idea I am working on, with some
success, that converts the tall slinder flame of many TLUD's, and packs it
into a small combustor. The compacted flame burns very hot and
complete. The design might also be able to assist rocket stoves,
something we will definately try.</FONT></DIV>

<DIV>With the fire starter , and its plunger/ piston dimensions (<-5'
length x ~½" O of cylinder with a ¼" ID for piston) and the sheer fact of its
precedent in history of use both in the UK and the developing nations,
it would seem perfect as a stove starter….Poor mans bomb calorimeter
eh ?</DIV>
<DIV><BR></DIV>
<DIV>This has hte potential of greater convenience and in that they have been
made ut of wood babboo etc etc over the eons, sugegsts somethign to upgrade
slightly and we are theoretically there.. </DIV>
<DIV>viz; </DIV>
<DIV>You drop in pea sized char tinder, or it rolls in thru a side port in
cylinder , punge down the down pressure closes a bottom one way flap or
poppet valve, makign the chamber air tight ..The tinder ignites then as you
withdrawy the piston the negative pressure int eh cylinder liftts open the
valve in the cylinder bottom and the ignited tinder drops directly down onto
the fuel bed ….Its got to be that convenient to compete with a
match or a bic lighter…</DIV>
