[Stoves] Test methods for cook stoves

Dear Frank

 

FRANK>Once all the testing is done we can do some field work with Beta
Versions by simply handing out stoves to a few along with a questioner - if
the manufacture wants. As long as the Conditions are all met (emissions,
stability, quality construction etc.) the stove is good to go. 

 

Not so fast.  Suppose we advertised for 'modes of transportation' with a
view to promoting energy efficiency.  A call for technology proposals is
issued.

 

Two candidates are submitted: a pogo stick
<http://www.bing.com/images/search?q=pogo+stick&qpvt=pogo+stick&FORM=IGRE>
and recumbent bicycle
<http://www.bing.com/images/search?q=recimbent+bicycle&qpvt=recimbent+bicycl
e&FORM=IGRE> . Both are submitted by enthusiasts who claim that after a
little practice they are efficient, inexpensive, and locally repairable from
available parts. They are RoHS compliant and meet all existing safety
legislation.

 

Sounds good.

 

We test them and decide that as both are people-powered they are excellent
devices because they use no purchased fuel at all, except food of course for
the operator. The marketing pamphlets look good:

 



 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

We rate their start-up speed and running costs and so on. Eventually they
are brought to the community to try. The early adopters are offered one
free. Results are mixed:





 

 

 

 

 

 

 

Various means are used to bring the new technologies into the public eye:



 

And various accommodations made for special needs:

 



 

Subsidies are introduced to make them affordable.

 



 

There are some unforeseen consequences:



 

Even with subsidies, sales were erratic:



 

So the clever marketing continued:



 

Complaints mounted:



But inevitably, rejection had to be admitted in the end.

 

The core problem was no one had asked the community what they needed for
transportation, what sorts of loads they carried and what sort of
performance they were looking for.

 

 

The 'beneficiaries' reverted to their traditional ways of getting around:

 





 

As with all types of development, you have to start with what people think,
do and want. 

 

Even when you explain how to get from where they are to where you want them
to be, they may not want to go.

 

Regards

Crispin
