Cooling of beverages is of large interest. Here a theoretical idea of how microwave ovens can be usedfor cooling beverages is presented. The proposed theoretical idea based on heat transfer features a microwavesafe (isoprene rubber) torus shaped rubber ring (MWSR) holding a liquid (L) at room temperature. Fullerenoldissolved in acetone (L) inside MWSR (L) will absorb energy directly from the microwave radiation and therebyincrease its temperature. The liquid to be cooled (B) will also absorb energy from the microwave radiation, butthe net effect is the cooling of B as the heat transfer is faster in L than in B due to L’s lower boiling point andheat of vaporization. The cooling fan of the microwave oven facilitates the heat transfer mechanism. Thebeverage B is theoretically cooled from room temperature (20 °C) to around 4 °C in around 58 seconds. Basedon heat absorption of fullerenol—which could be transformed from liquid phase to vapour phase—a beverageliquid (300 g water) in a glass put inside the microwave oven could be cooled (reversely heated) by the heatgenerated by the microwave oven. The user of the proposed method would be able cool 300 ml of beverage toless than 4 °C in just a minute using consumer microwave ovens.
