When first looking at Ashley Legg's proposed Smart Fridge on Yanko I thought it was another bar code scanner thing and was going to repeat "a green sustainable diet doesn't have bar codes." But it serves a different purpose: it is "for those who have shunted cooking to a hobby and rely more on designer microwave meals. The idea is to give you a fridge that is intelligent enough to come up with a healthy recipe, depending on what you stock in it. Not only that, it guides you with vocal instructions, spoon by spoon, till you dish out the perfect-wholesome meal."
So it looks at what you have in the fridge, puts together a healthy, balanced meal and teaches you how to cook it, all through its handy touchscreen electrochromic door. No more compost in the veggie drawer, less waste and a healthier diet. That's a smart fridge.
