However weird this design may be, I think the concept behind the zero-energy Bio Robot Refrigerator is intelligent. The refrigerator of the future will keep your food cool using a "special gel-like substance that suspends and cools food once inserted" according to designer Yuriy Dimitriev.
The crazy bio Robot Refrigerator actually suspends on the wall 9which ever direction you want) and uses the gel to cool your good. The gel does all the work which makes the appliance have 90% usable space. The gel isn't sticky or smelly so you're food will come out exactly how you put it in. This is smart!
