I highly recommend everyone see this article on
> Well-Tended Fires Outperform Modern Cooking Stoves
Very well done, with references, and providing some awesome quotations for future
articles by others.
> In fact, an electric cooking stove is only half as efficient as a

> rocket stove.
> And even though indoor air pollution is less of an issue with modern

> Improved biomass stoves have double or triple the thermal efficiency

> electric or gas cooking stoves.
3. Best thermal efficiency (out of 9 stove types) is 45% accomplished by Woodgas stove. (on chart).
4. It is disappointing that the article repeats data from a 2008 report that is now superceeded, and
cites the 2012 PCIA report of data collected by Aprovecho 7 to 8 years earlier (but publication delayed).
I hope that many Stovers will read this article from Low-Tech Magazine and make comments.
I am sending a separate message (with different Subject line) about delays in finding this
article (almost one year after publication) so that the two Subjects have different threads of discussion.
