Description The study was conducted in four phases. In phase-I, the baseline survey was carried out to study
the usage pattern of conventional hara in villages. In IInd phase, modified and low cost solar hara
were developed. In phase III Comparison of cooking quality of food cooked in conventional, modified
and solar hara were done and in Phase IV Feasibility analysis of modified hara and solar hara was
performed.
Under phase- I, Hisar district of Haryana state was selected purposively. Mangali and Shahpur
villages of Hisar I block and II block were selected purposively for easy accessibility. A sample of 50
respondents from each village were taken, thus to make a total sample of 100 respondents. Data were
collected personally with the help of well structured interview schedule. Findings revealed that
majority of the respondents were agricultural labor and were landless. Most of the respondents used
fixed type of hara, constructed with mud and used it for animal feed and for own food. Hara was
constructed by the homemakers in most of the households. Preparation of animal feed was taken
highest cooking time. For the storage of dung cakes most of the respondents used available open place
and the major problem of fuel getting wet was reported by the majority of respondents. Use of hara
creates several problems like irritation in eyes. Majority of the respondents desired that hara should be
more time saving. Results of phase-II show that model M3 (double wall mud hara with holes and
grate) was best in terms of power output (0.73 kw-hr) and thermal efficiency (20.17%). In case of solar
hara model SM1 was found to be best in terms of inside hara temperature (84.450C), water
temperature (72.700C) and thermal efficiency (19.44%). The results revealed in phase-III showed that
overall acceptability of kheer, khichadi and dalia prepared in modified hara was significantly higher
than solar and conventional hara. Phase-IV pertains the feasibility analysis of modified and solar hara
which shows that modified hara was considered as feasible and soar hara was considered as most
feasible.
