An Engine that Runs off Coffee?

Patented in 1816 by Reverend Doctor Robert Stirling, this style heat engine was designed to replace the notoriously dangerous steam engine during the Industrial Revolution. Simply place this engine on top of a coffee mug filled with freshly brewed java or a hot cup of tea and watch this portable powerhouse do its thing! No batteries required. You supply the mug and hot (or ice cold) beverage. For ages 14+
