[Stoves] [Possible SPAM] Box-1 Fuel

[Frank Shields]

Hi Steven,

I like this. All of it. I would add the particle density and length to 
width ratio. Good to add the moisture - I forgot and left off my list. I 
like the hydrogen but thinking of keeping the cost of equipment down so 
left that out.

You must have a TGA and CHN analyzer?

Now people just need to send you a sample of their fuel. Use their fuel 
to cook a meal using a specific stove and record the:

Box-2) Rate and amount fuel was added.

Box-3) name of stove

Box-4) utensils used

Box-5) process of cooking (stirring, flipping, covered)

Box-6) Quality of finished task and time it took

and any helpful notes along the way. You add your fuel data and we have 
the first of many reports.


Well done.

Regards


Frank
