There
are two daily power cuts
of four hours each in Pabal
and the surrounding villages.
Many of Pabal's inhabitants
use 12 volt batteries to
supply their energy needs
during power cuts. These
batteries are expensive
and often only last one
year. Once batteries have
ceased to hold enough charge
they must be replaced, which
is expensive, and although
they are often passed on
to someone with lower charge
requirement, they are still
eventually thrown away.
Thus there are two main
needs: 1) a cheaper method
of supplying electrical
energy during power cuts
and 2) a method of increasing
the life of lead acid batteries.
