Here is an interesting concept that has us thinking about the future of transportation: inflatable vehicles.
It sounds strange to consider, but some students at the University of Tokyo have an intriguing proof of concept (dubbed POIMO), and the aerospace has already proven out these ideas further.
The concept is basic, the body of the vehicle (think: frame, bodywork, seat, etc) is actually an inflatable bag that when pumped with sufficient pressure, becomes a rigid structure.
