Union Minister of State (Independent Charge) Science & Technology, Dr Jitendra Singh on 13 August launched India’s first Saline Water Lantern.

About Saline Water Lantern  

  • It uses the sea water as the electrolyte between specially designed electrodes to power the LED lamps.

  • It is the first-of-its kind lantern named “Roshni”. 

  • The Roshni Lamp has been invented by the National Institute of Ocean Technology (NIOT), Chennai.

  • This technique can also be used in areas where sea water is not available, as any saltwater or normal water mixed with common salt can be used to power lanterns.


  • It will bring "ease of living" to the poor and needy, especially the fishing community living along India's 7500 km long coastline.

  • It will also give a boost to and complement Prime Minister Narendra Modi's UJALA scheme launched in 2015 for the distribution of LED bulbs across the country.

  • It is not only cost-effective, but very easy to operate.
