Solar-Powered Lunchbox to keep food warm

A designer by the name of Teo Song Wei has come up with a solar lunchbox that uses solar energy to keep food warm. Rather than letting last night’s dinner get cold by the time you eat it, this lunchbox keeps your food warm. Great if you like a curry for lunch, rather than sandwiches!

Although this is only a concept design, it’s an interesting idea. However, personally, I’d be more interested in a solar lunch box where the contents are kept cool. There are many foods that you might have on a picnic (fruit, jelly, drinks, chocolate) that you’d want to stay cold. If there was a solar-powered cooling picnic hamper, then I’d be really interested.
