At home and in the backcountry, we all need a way to warm up leftover food. A new concept design by Jess Chee of Sydney offers an innovative solution: a hand-cranked food warmer. This handy little gizmo (which also doubles as stay-warm serving dish) uses kinetic energy provided by you, the hungry diner, to warm up your anticipated dish.
The uHeat (which comes to us via I Green Spot) works via a series of nested layers. The first layer, on the bottom of the dish, contains a pull-handle attached to a string. When you pull that string (with one hand securely atop the lid to keep your food in place), it generates energy via a Rebeck 36 mm brushless motor, which then provides juice to the next layer, a heating element. Fitted atop that layer is your basic stainless steel coated with Teflon, albeit a highly insulated one, that fits the lid tightly, to help contain the heat generated by your elbow grease.
We see this design as a great way to warm up leftovers without firing up the stove (although stirring might be an issue–can you shake this thing to distribute the heat?) and even better while comping in the great outdoors, where high winds can make setting up even an Whisperlite more than you want to deal with at the end of a long day. As an added bonus, the uHeat produces no carbon emissions.
