Crispin,
It's easy enough to create a*"short and hot" flame* from a biomass gasifier.
It was recently demonstrated for us in Illinois by Hugh McLaughlin
using one of his TinCan TLUD's (see photo).
(Note: With very simple device made out of tin cans, which
was/fan-powered/, the flame was very hot, but no more than an inch or so
tall...)
P.S. I am hoping to help get devices like the Jompy into Canada --
especially for our many isolated Northern communities (First Nations**),
who continue to deal with many water issues.
(We might wish to discuss this further sometime.)
** As highlighted by the /*Union of B.C. Indian Chiefs*/,
“The lack of safe drinking water to First Nation communities is
not caused by a lack of regulations. The lack of safe drinking water
is cause by a*lack of infrastructure, financial resources and
technical expertise* to ensure the safety of the water supply.”
P.S. There is even a Proposed /*Safe Drinking Water for First Nations
Act*/ (Bill S-11) before parliament right now.
http://www.ainc-inac.gc.ca/enr/wtr/esp/bll-eng.asp
The proposed legislation also addresses recommendations made by the
/*Commissioner of Environment and Sustainable Development*/ (Office of
the Auditor General), the /*Expert Panel on Safe Drinking Water for
First Nations*/, and the /*Senate Standing Committee on Aboriginal
Peoples*/.
The/*Expert Panel on Safe Drinking Water for First Nations*/,
established in June 2006, was one of the principal components of the
federal government’s March 2006 /*Plan of Action for Drinking Water in
First Nations Communities*/. The Panel held a series of public hearings
across Canada throughout the summer of 2006 and tabled its report in
November 2006.
Following the introduction of Bill S-11, the /*Assembly of First
Nations*/ issued a press release stating that the proposed legislation
"/will *not* meet the objective of ensuring First Nations have access to
safe drinking water/".
The /*Department of Indian Affairs and Northern Development*/ already
defines "priority communities" as those communities that have both
/*high-risk drinking water systems*/ and a /drinking water advisory/.
(Indian and Northern Affairs Canada (INAC) is just concluding a
_national assessment of First Nation water and sanitation systems_,
which will be released soon...)
The Bill has gone through 2nd Reading in the House of Commons and
their last meeting was March 9, 2011, but now that there is an election
everything is on hold. They still have to come up with a Committee
Report and the Report has to go through Presentation and Debate(s)
before going through a 3rd Reading before the Act comes into force,
which will likely be well /after the election/.
My hope is that with the introduction of devices like the Jompy that
we can help to */prevent/ the privatization of water infrastructure in
First Nation communities* by Governments that are intent on finding
"solutions" but don't have the budgets to build major water
infrastructure in all of these remote communities of the North,
especially given the constrained budgets of /all/ Governments (and
communities) right now.
(Note: The existing legislation essentially allows for "a private,
for-profit entity to build, operate and/or manage its water and
wastewater services" in First Nation communities.)
see: http://canadians.org/water/documents/FN/Bill-S11.pdf
*Risk of Water Privatization in First Nation Communities*
Subsection 4. (1)(c)(iii) states that “regulations may confer on any
person or body the power, exercisable in specified circumstances and
subject to specified conditions, to require a first nation to enter
into an agreement for the management of its drinking water system or
waste water system in cooperation with a third party.”
We are extremely concerned that this clause could open the door to
water privatization in First Nation communities. This subsection
provides the Canadian government with the power to force a First
Nation community to allow a private, for-profit entity to build,
operate and/or manage its water and wastewater services. To be clear
this clause alone does not guarantee the privatization of water and
wastewater services in First Nation communities. However, given
the/*lack of funding commitments in Bill S-11*/, this clause
facilitates water privatization on reserves.
Given federal financing trends and the negotiation of a trade
agreement between Canada and the European Union, it is possible that
the operationalization of this clause in the current economic and
political context will lead privatization in some First Nation
communities.
Canada is an enigma. We are considered a "first world" nation, yet *the
social, economic, and demographic characteristics* of remote /*Inuit,
Aboriginal and First Nations communities*/ in Canada often *mirror those
in /developing nations/*.
These remote, Northern communities are often challenged by limited
access to health services, low socio-economic status, high unemployment,
crowded and poor-quality housing, low educational achievement, and in
particular, concerns regarding basic services such as *drinking water
quality and sanitation*.
Multiple Canadian Government agencies are tasked with looking after
the people of the North. These include "*Indian and Northern Affairs
Canada*", "*Health Canada*" and the "*Public Health Agency of Canada*",
among others (yes, Canada does have /*two [2] _separate and autonomous_
Health Agencies*/... see: http://www.hc-sc.gc.ca
<http://www.hc-sc.gc.ca/> and http://www.phac-aspc.gc.ca
<http://www.phac-aspc.gc.ca/>).
It is now understood that conventional technologies for drinking
water treatment are no longer considered adequate for ensuring the
delivery of potable water to the communities of Northern Canada. This is
particularly true in smaller, more remote communities, where the
infrastructure for *treatment of* both *drinking water* and
*wastewater*** is often limited and can be /*very expensive*/.
**Note: *Wastewater treatment solutions* for the North could also
include technologies like /*Biochar Composting Toilets*/...
"Source water protection" is a relatively new concept for these
communities, and is NOT helped by the fact that most of the /*extractive
industries*/ [i.e. *mining*] is done in the North, and is very loosely
regulated, if at all.
(Most mining laws and policies in Canada do not allow for local
populations to consent (or not) to mining projects that will affect
their communities and environment. see:
http://www.yorku.ca/cerlac/EI/papers/Lapointe.pdf)
Thus, most of the Indigenous communities in Canada’s North have some
kind of */problems with drinking water quality /*that will continue to
be experienced in the communities of Northern Canada for years (and
perhaps decades to come -- as a result of the legacy of /*toxic waste
disposal*/), which highlights the need for*simple and inexpensive clean
water technologies* as a "back up" to the local water treatment systems
in these communities, since /centralized water treatment/ alone cannot
be relied upon to protect human health.
(The residents of at hundreds of aboriginal reserves must boil their
water before it is safe to drink.
http://www.cbc.ca/news/health/story/2008/04/07/boil-advisory.html)
"Ninety people in Canada die and another *90,000* get sick from
drinking contaminated water each year."
Some reserves have been under */boil-water advisories/* for _years_.
Amazingly, Canada does not have national drinking water quality standards.
A recent paper released by the */Sierra Legal Defence Fund/* reported
"/major drinking water concerns in First Nations communities and all
northern regions where drinking water treatment technologies are often
inadequate or poorly maintained/".
Compounding the difficulties in protecting sources of drinking water
is the reality that wastewater treatment systems that work in the south
are often /*not appropriate for use in the far north*/. (Wastewater in
the North is presently discharged to lagoons or natural wetlands that
are often _/frozen/_ for much of the year.)
The people of the North are in need of simple technological solutions
for the treatment of drinking water, which could become an important
tool for ensuring outbreaks of disease in these communities does not
recur due to contaminated drinking water issues.
Any drinking water treatment technology that is used must also be
easily adopted by northern (Indigenous) communities (in order to ensure
long-term sustainability).

If you remember the guy with the water heating coil (Jompy, UK?)...there is a guy Werner Schultz in Namibia making stoves for his staff that have a coiled pipe inside the stove body. Such a pipe could be cast into a stove top like the one in you photo, sort of a combination of the two ideas. Werner uses copper pipe.

If recasting a pot saves 15 or 25% of the fuel, or just makes cooking faster, that would be a quick and reliable improvement. Once the idea caught on all future pots would have fins. I saw a finned wok somewhere - I think at an ETHOS meeting (?). Clearly would help with a gas/biogas cooker, probably gasifiers too if the flame is short and hot.
