All team member of Spark is the people who are interested in to do some creative thing. The purpose behind choosing this project is to design something which helpful for normal people with the help of engineering technology. For our project of solar cooler for tesla model 3, we all are trying to build an energy efficient solar cooler which runs on the energy provided by sunlight. We are going to design a cooler which can be fixed in the back cabinet of Tesla Model 3. The main purpose of this is to provide a refrigerator with a car so people can keep their food and drinks cool or frozen during traveling. The main advantage of this cooler is it does not require any ice for cooling as well as it is portable and affordable for the customers. Our cooler design can be able to bring the temperature down to -10 C for that we are using thermometric effect. The cooler runs on the direct solar power or with a rechargeable lithium battery
