[Stoves] New document: Origins, History and Future of TLUD Micro-gasification..

[Frank Shields]

Dear Paul and Stovers,

Enjoyed reading your history of TLUDs and history of the ones contributing. Very interesting reading about the background of all involved in the process. Thanks for doing this.

But there is one view that I think is being overlooked as to moving the process forward - and that is the science.  You write in the document:

At the ETHOS 2012 conference, Anderson gave the Keynote Presentation (video is at www.drtlud.com) and made two declarations that are still true today:

1. Only 20% (approx.) of what can be learned about TLUD micro-gasification was then known (and in 2015 that percentage might be 25 or 30%), with much additional progress expected soon.

2. TLUD stoves are projected to account for 30 million of the 100 million-stoves target by the GACC for improved cookstoves by the year 2020. 



All of what has been done has been by trial and error. This only goes so far and perhaps we are already there. I agree we are only at the 20% knowledge base but to go beyond the 20% we need to get to the chemistry level. So to move forward we now need to advance the chemistry so to know what ratios and concentrations of gases are needed that enter the secondary to produce clean combustion. Then all adjustments made to the stove are now based on controlling those measurements. Working at this level will jump us well above the 20%. 

Thanks

Frank

At 18 pages length (this version 1.2 is text only), it is sure to contain some information that you do not know; at least I learned new things while writing it.

And I welcome everyone to participate during the future years, which look very promising indeed!!!  For starters, we can expect that TLUD and other micro-gasification will be in full swing at the November GACC Forum in Ghana (to which I am headed today via South Africa and Uganda for 3 weeks).
> Abstract / Executive Summary
> Two major cookstove entities, ESMAP and the GACC, wrote in their May 2015 technical report: “The most exciting technology trend in the biomass cookstove sector is the growing range of forced draft and natural draft gasifier stoves.” These words refer to TLUD stoves and related micro-gasification technology that originated in 1985. Their origin, history and future development are covered in seven time periods, each with progress that builds upon prior efforts:
> Pre-1985: Before modern TLUD micro-gasification – Processes observed, but not developed.
> 1985 ~ 1993: Inception – Reed, Wendelbo, LaFontaine and Hottenroth.
> 1994 ~ 2000: Early exposure to others – Miles, Larson, English, early Internet, conference in India.
> 2001 ~ 2006: Additional exposures and incremental progress – Anderson, BP-Oorja, ETHOS.
> 2007 ~ 2010: Slowly moving toward acceptance – Wendelbo, Belonio, Stove Camps, PCIA.
> 2010 ~ 2015: Enlightenment – BEIA Project, GACC, Roth, Winter, Harris, char-making for biochar.
> 2015 ~ 2020: Onward for dissemination and acceptance by users – Toward 30 million TLUD stoves.
> Conclusion (Author’s Comment) – Change of focus onto user acceptance and carbon into soils.
