[Digestion] Green Energy Testbed

[Anand Karve]

Dear Jonathan,
at least in urban India, the digestible waste generated by a family
amounts to hardly a kiligram per day. It is not enough to satisfy all
the cooking energy needs of a family. We provide household baogas
plants to individual families but warn them that they would still need
some other source of energy in the form of LPG, natural gas, kerosene
or electricity to supplement the biogas.  A community biogas plant is
feasible in a condominium, but we found that it was not possible to
provide individual families with biogas from the community biogas
plant, because there were disputes about the quantity of biogas used
by each user. We advocate using the biogas from a community biogas
plant for a common purpose, like charging the batteris of the lifts,
pumping water from the underground tank to the overhead tank, or for
lighting the common areas like parking areas, stair cases, corridors
etc. With the new LED technology, relatively less enery is used up in
lighting.
Yours
A.D.Karve
