Green Float: Eco-friendly Floating Cities at the Sea

The Japanese have always come up with unique solutions to complex problems. The Japanese conglomerate Shimizu’s proposal adds another stratum to the nation’s ingenious thought processes. A collaborative venture between Shimizu, Nomura Securities and Super Collaborative Graduate School, resulting in the creation and development of drifting townships in water, known as the Green Float, is being sought to be developed.

The Green Float townships are proposed to be situated at the Equator on account of the stability of the high seas there. The conceptualisation involves a clarified demarcation for city, district and country limits. Through such a high level of demarcation, the concept has been aimed at being more than just a visualisation.

Green Float

The Green Float township planning can be elaborated as follows:

  • The basic structuring of the living areas will be towers raised to a height of about 1000     metres. Through these towers, the impact of the wind has been sought to be minimised keeping the atmospheric temperature at a bearable 26 degrees Celsius.
  •  A district is demarcated as cells with a spread of one metre. One district, according to the innovators will have a populace of about 10,000 to 50,000 people.
  •  A group of such cells or districts is demarcated to be a city with an expected populace of about  1, 00,000 people.
  •  One country is a cluster of such districts and will have a populace of about one million persons.
  • In order to prevent sudden storms and cyclones, a protective wall standing up to 30 feet in height has been proposed to be built. In addition, elastic support bands circling the cells are also proposed to be attached the bordering Laguna to act as protective shield.

The most important aspect of this township is that it will follow stringent protocols for completely eliminating emissions of carbon dioxide along with recycling all the required commodities. Through these two addendums, a sense of eco-friendly and nurturing has been proposed.

Green Float

Like any other civilised township, the developers are sure that the Green Float will also develop through its population. The sustenance to the living areas will be provided by widening the cells like the spread of water lilies rather than a vertical growth. Furthermore, the Green Float will, as and when the need arises, drift with the water currents allowing a greater level of flexibility to the township.

The conglomerate Shimizu expects the project to become a viable reality by 2025. If the township does come into existence by that time period, it can be hoped that major problems pertaining to accommodation would be resolved through the Green Float.

  1. Something not quite on this scale was proposed about 20 years ago. The project was called Phoenix World City. The size was 250,000 GRT, which has been approached but not equaled by the RCCL Genesis class (220,000 GRT) only recently.
    One hopes that the designs have considered both typhoons and tsunamis, which are significant and recurring threats to maritime structures in that part of the world.

  2. The technology required to build such Floating Islands has been developed in Lebanon over the past 30 years, and a Floating Island is under construction in Jounieh, Lebanon.
