You can't argue with or remind somebody who is "willfully ignorant", they
are not "normal person" any more.

>> “Over the past decade a large amount of research has been dedicated in

>> cookstoves; primarily the performance efficiency and reduction of
>> emissions.
>> Unfortunately, as published literature has highlighted, the trade-offs

>> objectives is that improved cookstoves lack the same level of usability as
>> traditional cookstoves. Thus, users often return to using their
>> traditional
>> stoves and the potential impact of the improved cookstoves is never fully
>> realized. In order for improved cookstoves to have greater impact, there
>> must be

>> dusability. This research explores the challenges and benefits associated
>> with achieving the appropriate balance, and provides guidance on how to
>> more
>> effectively achieve this. A list of the most common customer needs from
>> around the world is provided for cookstoves. Interestingly, there are
>> needs
>> that are common to all cookstove users (global needs), and needs that
>> apply
>> to only a subset of users (local needs). Due to the diversity of such
>> needs,
>> there are many unique challenges that come with trying to satisfy these in
>> the design process. A design methodology is presented that accounts for
>> these challenges and helps balance the competing design objectives. This
>> methodology is demonstrated through the modification of a traditional
>> cookstove used in the Tambogrande region of Peru. This modification
>> includes
>> an inexpensive set of pot skirts that integrates directly with the
>> traditional stove. These pot skirts allow for varying sizes and number of
>> pots, and the use of traditional fuels. Laboratory testing, using the
>> Water
>> Boiling Test (WBT), identified the skirts’ technical improvements: 41.7%
>> increased thermal efficiency, 32.7% decreased fuel consumption, 28.8%
>> decreased time to boil. Field testing was performed to determine the pot
>> skirts acceptance and compatibility with the traditional cookstoves, with
>> over 75% of the participants recognizing some type of benefit. Although the
>> technical improvements of these pot skirts are less than other cookstoves
>> on
>> the market, the higher levels of usability are likely to lead to a more
>> positive enduser reaction, which could potentially lead to higher rates of
>> adoption and impact. Though this research is primarily focused on the
>> application of improved cookstoves, the need for more balance between
>> technical and user objectives is applicable to nearly all products being
>> designed for the developing world.”
