Energy independent travel:

Bus CerO2

In 2009, in cooperation with the Graz-based advisory network Austromotive, an automotive sector specialist, Spirit Design presented a design study for an energy-independent vehicle. Thanks to its innovative design and striking form, the completely CO2-free bus already communicates vitality, speed and the progressiveness of its drive mechanism by its very appearance. Its design is reminiscent of the busses of the 1950s.

In the context of this project, Spirit Design was able to benefit from the generally favourable environmental footprint of a bus and, with the CerO2, drew further untapped potential. A bus in and of itself already has a lower energy consumption per passenger than a car. In addition, plenty of surface area and usable space remains available for implementing innovative technologies. Spirit Design’s goal is to make a CO2-free drive concept commercially viable – especially for large vehicles within the public transport sector.

The vision of the CerO2 project is to enable complete independence from any external energy supply. The aim is to have the primary energy required for propulsion entirely produced by the vehicle itself. The underlying principle is called The Passive Car Technology©, putting forth the combination of the latest energy recovery systems, which are then adapted to the specific requirements of automotive propulsion.

The energy independent bus takes advantage of the latest technologies: electromechanical energy recovery during braking stores kinetic energy generated during speed reduction. Power for the operation of additional uses such as air conditioning is supplied by a permanent magnet shock system at front and rear; thermoelectric generators are used for the conversion of heat in the exhaust, on the dashboard or in the car seat; vertical wind turbines operate as a small power plant when the vehicle is at a standstill in addition to body-mounted solar panels.
