This presentation introduces a marketing plan for "Salt Water Light," an energy lamp that generates power through a simple process of adding two tablespoons of salt to a glass of water or seawater and using an LED bulb. The salt water light requires no batteries, electricity, or other fossil fuels, making it durable and useful for charging devices during natural disasters. The presentation is prepared for an associate professor's marketing management course and delivered by MD. Shams Akhter.
