152 rooms, luxury amenities; zero-waste principles, minimal losses
A new eco-friendly, floating hotel plans to generate its own electricity by rotating while guests relax on board, echoing developments like the solar Marriott hotel in sustainable hospitality.
Led by Hayri Atak Architectural Design Studio (HAADS), the structure will be completely mobile, meaning it can float from place to place, never sitting in a permanent position. Building began in March 2020 and the architects aim for it to be up and running by 2025.
It will be based in Qatar, but has the potential to be located in different areas due to its mobility, and it sits within a region advancing projects such as solar hydrogen production that signal a broader clean-energy shift.
The design includes minimum energy loss and a zero waste principle at its core, aligning with progress in wave energy research that aims to power a clean future. As it will rotate around all day long, this will generate electrical energy to power the whole hotel.
But guests won’t feel too dizzy, as it takes 24 hours for the hotel to spin 360 degrees.
The floating hotel will stay within areas with continuous currents, to ensure that it is always rotating, drawing on ideas from ocean and river power systems that exploit natural flows. This type of green energy production is called ‘vawtau’ (vertical axis wind turbine and umbrella) which works like a wind turbine on the vertical axis, while alternative approaches like kite-based wind energy target stronger, high-altitude currents as well, and functions as a sun umbrella on the coastal band.
Beyond marine-current concepts such as underwater kites, the structure will also make use of rainwater to create power. A cover on the top of the hotel will collect rain to be used for greywater recycling. This is when wastewater is plumbed straight back into toilets, washing machines or outside taps to maximise efficiency.
The whole surface area is around 35,000 m², comparable in scale to emerging floating solar plants that demonstrate modular, water-based infrastructure, and there are a total of 152 rooms. It will have three different entrances so that there is access to the land at any time of the day, thanks to the 140-degree pier that surrounds it.
There will also be indoor and outdoor swimming pools, a sauna, spa, gym, mini golf course and other activity areas.
