Saline Water Lantern will bring “Ease of Living” to the poor and needy,
particularly the fishing community living along the 7500 Kilometres long
coastal line of India: Dr Jitendra Singh
Saline water powered Roshini LED lamps will also boost and supplement Prime
Minister Narendra Modi’s UJALA scheme

Union Minister of State (Independent Charge) Science & Technology;
Minister of State (Independent Charge) Earth Sciences; MoS PMO, Personnel,
Public Grievances, Pensions, Atomic Energy and Space, Dr Jitendra Singh has
launched India’s first Saline Water Lantern which uses the sea water as the
electrolyte between specially designed electrodes to power the LED lamps.
Dr Jitendra Singh
unveiled the first-of-its kind lantern named “Roshni” during a visit to SAGAR
ANVESHIKA, a Coastal Research Vessel, operated and used by the National
Institute of Ocean Technology (NIOT), Chennai for coastal research. The
Minister said, Saline Water Lantern will bring “Ease of Living” to the poor and
needy, particularly the fishing community living along the 7500 Kilometres long
coastal line of India.
Dr Jitendra Singh
said that Saline Water Lantern will also boost and supplement Prime Minister
Narendra Modi’s UJALA scheme launched in 2015 for distribution of LED bulbs
across the country. He said, Roshini Lamps along with Power Ministry’s schemes
like Solar Study Lamps will be driving a vibrant renewable energy programme
aimed at achieving energy security, energy access and reducing the carbon
footprints of the national economy.
Dr Jitendra Singh
also pointed out that this technology can also be used in hinterlands, where
sea water is not available, as any saline water or normal water mixed with the
common salt can be used to power the lantern, which is not only cost-effective,
but very easy to operate. The Minister lauded the NIOT team for inventing the
Roshini Lamp and advised them to transfer the technology to the industry for
mass production of this multipurpose lamp which can be of immense help in rural
and remote areas and in the times of the disasters.
Later, Dr Jitendra
Singh along with the Secretary, MoES Dr M Ravichandran visited the laboratories
and hoisted tricolour on board the ship. Extending the campaign of ‘Har Ghar
Tiranga’, to ‘Har Jahaj Tiranga’ the Minister hoisted the Indian flag on board
the vessel. He also met the senior scientists of NIOT onboard the vessel and
reviewed the progress of the implementation of the Deep Ocean Mission of India.
Dr Jitendra Singh
also reviewed the progress of NIOT developed Low Temperature Thermal
Desalination (LTTD) technology for conversion of sea water to potable water,
which has been successfully demonstrated in Lakshadweep islands. He informed
that three desalination plants based on the LTTD technology have been developed
and demonstrated at Kavaratti, Agati and Minicoy Islands of Union Territory of
Lakshadweep. The capacity of each of these LTTD plants is 1 Lakh litre of
potable water per day.
Secretary, MoES Dr
M Ravichandran apprised Dr Jitendra Singh that based on the success of these
plants, Ministry of Home Affairs (MHA) through Union Territory (UT) Lakshadweep
has entrusted the work of establishing 6 more LTTD plants at Amini, Androth,
Chetlet, Kadmat, Kalpeni and Kiltan with a capacity of 1.5 lakhs litres/day.
The LTTD technology is found suitable for Lakshadweep islands where the
required temperature difference of about 15⁰C between sea surface water and
deep-sea water is found in the vicinity of Lakshadweep coasts only as of now.
The cost of
desalination plant depends on a number of factors inter alia which includes
technology used and location of plant. The total cost of the six LTTD plants in
Lakshadweep islands is Rs 187.75 cr.
