With rising sea level and scarcity of developable land in Hong Kong, more urgent and extreme measures have to be taken to develop Net Positive built environments. Large scale land reclamation can no longer suffice nor does it answer ecological concerns.
The Hydro Tower is the response to such an extreme condition. It is a campus of different living environments floating or parked in the ocean. The campus’s “Infrastructure Sector” is an inverted tower plunged into the ocean. It forms a huge open atrium in the middle to collect sea water, with recycling factories on the lower level, and a hydroelectric power generator at the bottom to generate clean energy 24/7. Not only does the tower clean the sea water constantly it also recycles the debris that are deposited into the tower.
Based on the “Infrastructure Sector” typology, other essential functions of society such as the “Living Sector”, “Farming Sector” and “Wilderness Sector” are designed and carefully placed around each other to form a self-sustaining community. This group of inverted towers will be able to produce food, energy, potable water and other upcycled goods. The towers are connected with a walking path where habitants can roam freely around each sector.
The tower shown here is the “Living Sector”, which consists of living units with ocean views. Every square meter of the tower is used efficiently as a sustainable living space for the environmentally-conscious urbanites. The “Farming Sector” will be the main tower that produces food from pastoral farming, indoor farming, and aquaculture. Biogas generated from this Sector will also be used to generate power for local use. The “Wilderness Sector” will provide open space as well as some entertainment facilities to add to the social dimension of Hydro Tower living.
Transportation-wise, the “Hydro-tower Community” can access inland or other clusters with drones or underwater autonomous vehicles. Of course swimming is most enthusiastically encouraged! Not only can it be a sustainable development for the future with efficient use of resources and recycling, it is also a “made in Hong Kong” invention that is scalable to anywhere in the world leveraging our innovative design talents and new real estate opportunities.
