In the UK, the instantly-recognisable tinkling of the Mr. Whippy truck approaching is the hallmark sound of summer. Those old white trucks might deliver melty dairy goodness, but whatever comes out of their tailpipes can't be good for the planet—which is what makes these solar-powered ice cream carts so awesome.
Designed by Springtime, a Dutch design venture, the carts have solar panels on the roof, which juices up the batteries to keep the scoops ice cold. It totally makes sense that in the thick of July, you'd use the oppressive power of the British sun to keep the fridge running. [Inhabitat]
