From the beginning we have ensured that our vision must be technically feasible. Not in the laboratory but in practice, with solutions that are in the market now. Hence we prevent wasting time on pipe dreams.

So we take a conservative approach to innovations. On the other hand, we keep an eye on promising developments. The vision is fixed, but not the implementation. If new proven innovations come to market during the development of plans out of the vision, then we will also consider them. However, waiting for perhaps something better to come a long is no reason to delay realization. One has to start somewhere.

This section indicates how the vision can be implemented and explains some considerations taken.
