[Stoves] Thanks to all, from EWB Princeton in Peru

Dear Charlie

It is very commendable that you have such a variety of shapes, materials and
techniques combined to make a really good product.  I look forward with
interest to the photos. If you have a complete set showing all the steps,
that will be ideal.

Did you get any measurements of fuel consumption for any particular cooking
task?  Did you get any wood moisture readings (by weighing in some way)?  I
presume that you will be getting feedback from the users sooner or later
about their perceptions of fuel use.

Thanks
Crispin
