[Stoves] the price of bottled gas

[Anand Karve]

Dear Stovers,
As cooking energy, biogas can easily replace LPG or CNG. Biogas gives a
blue flame without smoke or soot, its flame intensity can be controlled at
will and turning it on or off is as easy as LPG. Our work showed back in
2003 that dung is not needed for biogas production and that material like
sugar, starch, cellulose, digestible protein and fats can all be used as
feedstock. In our city, waste flour, swept from the floor of a flour mill
is available for about US Cents 10 per kg. 3 kg flour give enough biogas to
replace one kg LPG costing US Cents 80 (subsidised price) or US$1.6
(unsubsidised price. If you have a few green leafy plants around your
house, or have access to the local vegetable market waste, 10kg fresh green
leaves (available for no cost) would yield enough biogas to replace about 1
kg LPG.
Yours
A.D.Karve
