I thank Kirk Smith for getting the ProPublica article to our attention
as soon as it became available.
Read. Perhaps weep. Work harder. Learn about the opposition to
Personally, I am disappointed that there was not a glimmer of
recognition of what the TLUD micro-gasifiers HAVE ACCOMPLISHED and have
shown to be possible in terms of (A) quite clean cookstoves, (B) STRONG
user acceptance, and (C) that carbon credits ARE working with TLUD
gasifiers. The authors (and those who were interviewed and quoted)
seem to be totally unaware of the REPORTED IN 2016 success in the
Deganga pilot study with 11,000 Champion TLUD stoves (see
www.drtlud.com/deganga2016 ) And lesser known is that the number of
households has invreased to about 40,000. And we are looking for
funding for scale up for the larger numbers.
But this article will make it even more difficult to get funding for
scale-up of the TLUD stove success story. However, if it can stop
wasted money on the UNsuccessful stove-types that are indicated (but not
named) in the article, I am not against that.
This is now mid-2018. The GACC will claim success to reach 100 million
households by 2020 on the basis of LPG stoves in India. And then what????
Read the article. It is worthy of some discussion here on the Stoves
