I would request thjem to post occassional anecdotal reports on what is the actual usage of the Cookit or other Solar Cookers that exist there.
I divide usage into 2 parts.
Firstly on how many days with clear sun, the cookers get used. Say Solar cookers get used 150 days out of 200 days of clear sun shine.
Secondly out of 6 to 8 hours of sun shine on a clear day, for how many hours the Solar cookers get used/ Do they get used for 3 hours out of 6 hours of intense sun light or they are used only for 1 to 2 hours per day?
Both type of data indicate how well the Solar Cooker solves actual needs of people versus the needs as percieved by the designer.
Thanks in advance
