[Stoves] farmed fuels

[Ronal Larson]

List and “foodandfuel"

	1. Apologies for an empty message a few minutes ago.  No idea what I did wrong.

	2.  Thanks to Kirk Harris for starting this thread on fuels coming from farms.  In this case, corn cobs, which we have seen a good bit of -  but I recall no stove list message quite like this one    Repeating the attachment:




 	3.   Thanks to Teddy (cookswell) for describing his techniques for making char from cobs - but his char-making did not seem to involve cooking.

	4.  .  “”foodandfuel” is almost certainly a creation of Christa Roth. (See   http://foodandfuel.info/foodandfuel/ <http://foodandfuel.info/foodandfuel/Archive_files/HERA%202011%20micro-gasification%20manual%20V1.0.pdf>. And especially.
      http://foodandfuel.info/foodandfuel/Archive_files/HERA%202011%20micro-gasification%20manual%20V1.0.pdf <http://foodandfuel.info/foodandfuel/Archive_files/HERA%202011%20micro-gasification%20manual%20V1.0.pdf>

	Maybe Christa wrote this specific list entry, but if not, could we hear more about “foodandfuel” in Malawi.  Seems like some excellent stove work going on there.

	5.  My questions on this particular stove:
		a.  What char yield is obtained?  25% possible?
		b.   Can you supply the dimensions for the components.  (Diameters and heights). A sketch would help (wanting to see both primary and secondary ari flows)
		c.  Of particular interest is your use of a skirt - which we don’t see enough of.  How important for efficiency gain?
		d.  Is there primary air control?   Might the primary air receive preheating?
		e.  This looks like you must be cooking for better than free  - zero cost fuel and a salable (biochar) product.  Can you estimate the months of operation to pay off the cost of the steel parts?  (Over a 3-stone fire competition).
		f.  Has anyone done a simple water boiling test?  Might you be at Tier five?
		g.  Is anyone making these for sale and at what price?     How many in use now?

Again congratulations for a nice product design.

Ron
