Abstract: Soldiers are the Army’s most important resource. Soldiers play a vital role to protect one’s country. The term soldiers include service men and women from the Army, Air force, Navy and Marines. They will always be the one responsible for taking and holding the duty in extreme weather conditions throughout the year. While providing security to the nation, they may face troubles in extreme hot/cold weather conditions. Both very cold and very hot temperatures could be dangerous to health. Excessive exposure to heat referred to as heat stress and excessive exposure to cold referred to as cold stress. In a very hot environment, the most serious concern is heat stroke. At very cold temperature, the serious concern is the risk of hypothermia or dangerous overcooling of the body. In this project we are going to design an E-Uniform which gives better protection to the soldiers who are working in extreme weather conditions. This uniform will make the soldiers to work in any kind of environment. And we are going to design a refrigerator cum oven in this project. By harnessing solar energy, this refrigerator cum oven is able to keep perishable goods and dairy cool in hot climates and warm in cold climates. It is also used to keep much needed vaccines at their appropriate temperature to avoid spoilage. The portable devices can be constructed with simple components and are perfect for areas of the developing world where electricity is unreliable or non-existent.
