dear Mr Warren
regarding Dr karve model it should work in ur location also but production
of biogas also depend on temperature as dr,karve digester based on
mesophilic bacteria and temperature range is 27-35 degree centigrade is
suitable and in your area its 45 deg fareinheit second did u chek with
starter its better to get old dung ,and also mechanical i.e. leakage
fitting
secondly u may go with converting it in thermophilic it just need
additional insulation and one pv for heat water
me i am thinking it to work with thermophilic also if i got will convey
thanx
