Dear Paul v.d.S.

Could you please clarify about the expression "top feed stove."  Specifically
describe how and when the fuel is feed into the stove.

I see at least 2 options:

One is the classical T-LUD method of "fill the fuel chamber, ignite at 
the top,
let it pyrolyze, then either empty out the char or let it continue to consume
the char."

The other is what has been discussed here at the "trickle feed" (or trickle
fuel) method in which the fuel is continually added (at 20 to 40 second
intervals?) in small amounts dropped in over the top of the stove.  The 
trickle
of fuel could be from the very beginning or done after the pyrolysis stage has
been mainly completed.

Which method is what you use or recommend for the Philips stove usage 
in India? Or if something different, please explain.

Concerning the thermal efficiency of about 40%, please describe the 
arrangement
of the pot (size, with skirt?, stainless steel?, with lid on?, etc) as it was
used on the stove when the testing was done.

Thanks.

Paul A.
