[Stoves] Hi tech cow dung technology (Anil Rajvanshi)

[Anand Karve]

Dear Nikhil,
producing biogas from dung is a very wasteful process. 1 kg (dry weight) of
dung, which would yield 4000 kcal energy if burned,  yields only about 200
kcal energy, if converted into biogas. In the city where I live, cowdung
cakes are used in certain religious rites. They are sold at a lucrative
price of about 9 USCents per piece. That would be a very attractive
business for a Dutch dairy farmer, but drying the dung would be problematic
in a country like holland.
Yours
A.D.Karve
