While getting his Masters in Industrial Design at Germany's Muthesius University of Fine Arts and Design, Erik Mantz-Hansen chose an interesting employer to intern with: The Steinway & Sons piano factory in NYC, which we looked at here. Mantz-Hansen produced renderings for them.
Perhaps it was in New York, with all of its food trucks, that Mantz-Hansen was inspired to design his Guerilla Kitchen.
"Guerilla Kitchen is a compact, modular street food kitchen designed as a less costly alternative to the conventional food truck. High mobility and small size allow for efficient navigation through dense urban areas and enable the occupation of tight spaces. Guerilla Kitchen is a tool designed to address the needs of any type of street food production and empower more people to start a street food business."
I especially like that he's added the touch of stair-climbing wheels.
