The Solaris Global Cruiser is the first vehicle/concept published by Duffy London.
It consist of a 40 meter motor boat able to produce its own fresh water, deal with its own waste and provide its own power. 
The system would use the rest periods of the yacht to maintain and keep the vessel fully fueled, continuing to top up whilst travelling. Using state of the art materials and the very latest battery and solar technology, creates a super-yacht that could possibly never require refueling.
