A lot of people cook while they're trying to accomplish other tasks, so the concept for the Free Cooker by Ahhaproject is a brilliant solution to increased domestic efficiency.
The hi-tech elements were designed for Candy Group with the idea that each individual component can function on its own. When connected in place on top of the oven, the separate parts can be programmed through a central set of controls, but there's no incentive not to disengage and relocate a portable hotplate outside of the kitchen.
You could easily bring one element into your office for making coffee, one into your bedroom for making breakfast, and one into the laundry room while you fold your clothing. The most common use of the Free Cooker by Ahhaproject may to simply set one down on the table to keep your meal hot.
