And now, for all you Bento box fans/solar gadget enthusiasts, the perfect device with which to inspire envy among your co-workers, while keeping your meal piping hot (or crispy cool): the Sunflower Lunchbox concept from Edita Barabas (which comes to us via Yanko Design).
This handy little appliance keeps the warm stuff warm and the cool stuff cool via a series of stacking compartments, separated by a collapsible flower-like contraption laced with solar cells. This device charges up through a suction cup that goes on a sunny window–after which, it will individually heat or cool compartments with the touch of a button.
When the lunch box is snapped together and closed, the compartments are connected to an electrical circuit through the three “lids.” Once the lunch box is opened, that electrical circuit is broken, allowing you to partake of your afternoon nosh without fear of being zinged.
While the obvious application is lunch at work or school, this invention also seems ideal for dinners in remote locations–leaving us dreaming of a crisp, solar-refrigerated salad and steaming lasagna at 5,000 feet.
