<p>Steven Califf from Rockford, Illinois, is retired after a career of working on steam turbines in nuclear power plants. That clearly gave him the inspiration for this remarkable steam engine replica which doubles as a barbecue steam smoker. Steven worked on the invention for three years and once it was ready, he presented it to the world in a video recorded by his wife, Janet.</p><p>The video shows him demonstrating the valve and the bell, while also checking on how well the chicken is cooking! The footage was watched nearly half a million times in a couple of days. Credit: YouTube/Janet Califf</p>
