zephyr - car concept
Zephyr is an electric vehicle which generates energy by itself. The two-seater is not just a car but a 24 hour power station as well. A large size back wheel consists of a conceptual combination of two contrary spinning wheels. Furthermore the unit can be rotated in an overhead position. These functions are allowing the car to convert the head wind (while driving) as well as the natural breeze (while parking) into energy. Zephyr would use its capacity well in windy urban regions like Chicago (U.S.) or Hamamatsu (Japan).
