I could have used this handy device about three summers ago when I had no kitchen. Instead, we had to make due with a garden hose and a BBQ rigged out of bricks, rocks, the grill from an old Land Rover and charcoal.
I guess German ingenuity is a little different than the American kind.
The À la carte from Stadtnomade is a portable modular kitchen that works as an electric stovetop and sink. Just plug it into to electricity and water sources and you are set. At full set up the kitchen is about 7 feet long, 3 feet tall and 2 feet deep. DesignSpotter points out that the kitchen, when collapsed for transport, is only about 2 feet square and 1 foot deep for each unit.
