Availability of power and energy are luxuries
few can afford in the developing world. Either populated communities are not
connected to the grid, or there is wide spread load shedding due to inadequate
electricity production, or the soaring costs of power leave the poor with no
choice but to spend their days in the dark. Slums and shanties often have
hundreds of inhabitants stuck together wall-to-wall, thus blocking out natural
light from reaching their rooms. Use of candles and kerosene lamps often prove
to be hazardous in these shantytowns. As darkness looms from above and within,
innovation and brilliance steps in to change the dismal state of affairs.
Initially in 2002 Brazilian Alfredo Moser
developed the idea of using plastic bottles as a source of light. Expounding
upon the idea and holding the adage of “Reuse, Reduce and Recycle” close,
Phillipine’s My Shelter Foundation used sunlight, the laws of refraction and
readily available PET bottles to light up about 25,000 low income homes.
The
logic is simple. “The scheme uses plastic bottles
filled with a solution of bleached water, installed into holes made in shanty
towns' corrugated iron roofs, which then refracts the equivalent of 55W of
sunlight into the room – during the day, at least. It takes five minutes to
make, and using a hammer, rivet, metal sheets, sandpaper and epoxy, it costs $1
to produce.” (http://www.guardian.co.uk/environment/2011/dec/23/sunlight-bulbs-plastic-bottles-light)
The
bottles are set in place using metal seals, thus making maintenance unnecessary
as they prevent against contraction, expansion and waterproofs the bottle to
prevent it from slipping down. This brilliant innovation has now allowed the
women of those dwellings to sew or engage in other productive activities they
were deprived of due to living in the dark, thus creating jobs and generating
economic activity. Children can study and play inside now- keeping them safe
and off the streets.
Additionally,
this ‘solar bulb’ is environment friendly and is a feasible alternative to the
more expensive green options available in the market today.
