To protect the ecologically-fragile islands
of Sundarbans from noise and air pollution caused by motorised 'jugaad'
vans, an alternative public transport model has been built using
solar-powered electric vehicles. Research body 'The Energy and
Resources Institute' (TERI) and Paris-based Mlinda Foundation has
developed the new model under which 50 solar vehicles would soon be
launched in Patharpratima block of Sundarbans with consent from the West
Bengal Renewable Energy Development Agency (WBREDA). Locally known as
'Vano', the motorised rickshaw vans are so far the only form of public
transport available for 40 lakh people living in the Sundarbans delta, a
UNESCO World Heritage Site three-hours drive away from Kolkata.
Assembled with improvised arrangements, also known as 'jugaad'
technology, it is powered by a diesel engine that uses an adulterated
mixture of diesel, kerosene, naphtha, used engine oil, etc which gives
out highly polluting emissions. Under the pilot project, TERI would
roll out 50 solar vehicles made by Tata Motors along with two solar PV
based charging stations in a fringe island of the Sundarbans. "This
electric rickshaw can accommodate eight people and after getting charged
with solar energy for 4-5 hours at the station, the 20 Ah battery can
run for 40-50 kms in a day," TERI's Parimita Mohanty told PTI. The
charging station would be equivalent of a petrol pump and its 500W of
solar module would charge the rickshaws. Once the project is
successfully demonstrated in the first phase, TERI would engage social
entrepreneurs to scale up the model in Sundarbans. "We want to make it a
commercially viable model as we will ask the rickshaw operators to buy
the vehicles," Mohanty said. The cost of the solar rickshaw would be
around Rs 4-5 lakh while the charging station would cost around a lakh.
"We did a trial study with two such vehicles for three months to
understand how these rickshaws can be run in the region after which we
came up with this model," the TERI researcher said. Besides zero
emissions, the solar vehicles would be noiseless too.
The engine of 'jugaad' vans are notorious for creating noise pollution as they disturb birds and marine life while plying along the river banks. Home to the Royal Bengal Tiger, the archipelago of Sundarbans is known for its rich wildlife and mangrove forests. A baseline study by Mlinda Foundation estimates there are around 19000 such 'jugaad' vans in the entire Sundarbans. "The carbon content is very high in the adulterated diesel they use and therefore these vans are the major source of pollution inside Sundarbans," Mohanty said. For locals and tourists who venture into the villages, these vans are also risky and uncomfortable. Absence of 'pucca' roads is another issue as it is estimated that only about 300 km of metalled road exists in the entire area of about 4500 sq km of Sundarbans.
