How do you design a compact cooler to serve up one cold energy shot at at time to deter theft? That was our challenge with this project. The solution was to use thermoelectric cooling in a molded housing and a cleverly designed rotating dispenser that only allows the consumer access to one shot at a time. The shots are restocked by the clerk via a hinged locking lid. Serpentine channels inside feed the shots down into one of the two dispensing barrels, which also make a clicking noise to alert the clerk that the product is being dispensed.
