Designers from Smart Cities at the Massachusetts Institute of Technology (MIT) Media Lab have designed the City Car, an electric car that is both shareable and stackable. Using a folding axis, the lightweight City Car collapses and stacks into other City Cars, just like shopping carts at the grocery store - - eight stackable cars can fit in a single parking space. Meanwhile, car sharing is a great alternative to public and private transportation. Rather than having to return a stackable, shared car to the location where you borrowed it, the City Car plan would allow you to drop it off at your choice of location. When you drop it off, it locks in place behind a row of other stacked City Cars, just like luggage carts at the airport. And, while stored, the City Car's lithium-ion batteries could charge on racks connected to the city's power grid.
