Self Regulating Cooler

The motivation behind our project came from the problem of always having to deal with ice when camping, which depending on if you are in a remote area or not, can be quite difficult to obtain. In order to solve this, we are designing a portable cooler that will ideally be able to self regulate without needing a direct power source for a certain amount of time. The more expensive solar panel you get, the longer this time will be. In order to do this, we are using semiconductor devices that use the peltier effect, which creates a cold side and a hot side and then we will expand the cold side to the environment of our cooler. In order for this to work efficiently. You have to draw as much hot air as you can away from the peltier in order for the cold side to get as cold as possible. The main problems we ran into is how to effectively cool the entire cooler environment since the peltier itself is only 40mmx40mm. As of right now, we have the entire cooler built and get a decrease in temperature, with the next step being getting it to turn on and off within a certain temperature bound and then also charging the battery with the solar panel
