It seems like a small step, but has a potential to be a big leap in the direction of sustainable electrical energy for a large section of the world population. Many a time small ideas like these translate into big breakthroughs. There are many areas in the world where salt and sea water is in abundance but they are starving for electrical energy.
The developers of this unique lamp have come up with a product that they claim can produce enough energy to light a lamp for 8 hours a day by just adding 2 table spoons of salt to 1/3 glass of water. The lamp will give off around 90 lumen with a vanilla low power LED bulb. Sea water can also be used to operate the lamp.
The lamp comes with a USB slot that can also be used for charging your phone.
The Anode, however, has to be replaced every 6 months which is an extra cost. There is no danger of fire or dangerous fumes as in case of many kerosene lit lamps. The SALt lamp will cost you $35. [Buy It]
