Emission free cruise?

Is this the new way to cruise in the future? Solar panels for electricity,Tanks that run on kitchen waste?

Designs for what has been labelled the world’s “greenest” cruise ship have been finalised – while an announcement regarding dates for its maiden voyage, pencilled in for 2020, is expected at the UN Climate Change Conference in Paris this month. It’s a 55,000 tons ship developed by more than 30 engineers and will be environmentally-friendly. Is this the way to go? The climate on board – including heating and air conditioning – will be maintained naturally, a “closed-loop” water system will see all waste water purified and repurposed, along with rain and seawater, for irrigating the on-board garden.t all adds up to a promise of “zero emissions… as well as no sea dumping”. That may open the flood gates for more? only time will tell. Also would that bring the cruise prices down? I am not too sure, what do you think?
