[Stoves] No subsidies in TLUD char peoduction

[Ronal W. Larson]

Julien, cc List:

	A wonderful website and success story.  I don’t think there is a better advertisement for the combination of TLUDS AND biochar.

	Four questions I don’t see answers for at your website:

		1.  The cost and payback period considering all aspects - higher fuel costa and the sale/use of the char?

		2.  Whether users are preferring to keep and use the char or selling it?   (The photos all showed saving and using the char - for improved NPP reasons and/or savings on commercial fertilizer)

		3.  Can you say more about the outer cylindrical insulating segments?  Fired or cast?  Available from some other application or special for these stoves?
	I ask, wondering if the interior metal cylinder might be replaced by this cement or ceramic piece.   Bill Knauss and Gordon West have been experiment with cast cement with char (formerly paper) in the “bricks”  (which could be cylinders).  Being called “charcrete”.

		4.  Are you looking for additional funding or have enough?

	Again,  congratulations on really fine work. (especially including the web site).

TLUDs and biochar have to survive on their own merit.  What subsidies can do is help to speed up the dissemination of the technology and scaling-up.

The stove is not fragile, because its outer body is made of light concrete, so you can stand on it, or bounce a child off it.

Their main reasons for liking it over a traditional stove are (1) a 25% saving of fuel, (2) low smoke emissions and 'clean' cooking, (3) ability to turn down by half, (4) ability to stand whilst cooking, and (4) greater comfort with cook experiencing less radiant heat.

It was our expectation that biochar could be the critical facilitator in cookstove acceptance.

They see biochar as a means to increase yields whilst being able to reduce expensive fertilizer inputs.  These trials are ad hoc, and not good for making general recommendations.   In the mean time, however, biochar from the Akha Biochar Project has been sent to a couple of local universities, and graduate students are using it for their thesis research.

Being able to provide evidence that char is being made, and used as biochar has a cost.  However, if the data is combined with other socio-economic information, it can be very useful to see who is benefiting from biochar, and the effects on food security and economic welfare.
