武汉被称为“千湖之城”、九省通衢,但武汉又是大家熟知的“火炉”城市。这一点好像和 “湖泊越多,城市越凉爽”的常识相悖。而湖泊面积的逐年减小正式武汉高温的重要诱因。该设计旨在发掘武汉当下的城市危机,畅想未来技术带来的新型城市和社会方式。想象未来的湖中城市将不仅是人类追寻丰富的人居体验的垂直都市,而且是应对自然变化的垂直湖泊、是一个建立跨越地壳、水层和空气层的城市新秩序的探索之塔。

Wuhan is known as the "city of a thousand lakes(千湖之城)" and the "thoroughfare of nine provinces(九省通衢)", but it is also known as a "furnace" city. This seems to contradict the common sense that "the more lakes there are, the cooler the city". The decrease in the size of the lakes each year is a major cause of the high temperatures in Wuhan.The design aims to uncover Wuhan's current urban crisis and to imagine the new urban and social ways that future technology will bring. It will not only be a vertical city for urban habitation and experience, but also a vertical factory for energy crisis, a vertical lake for natural changes. It will be a Probing Tower, which establishes a new urban order across the crust layer, water layer, and air layer.



研究发现 - 火炉城市的诱因是收缩的湖泊
Research Observation-Shrinking Lake In Scorching City
从1960至2020年,这个中国最大的城中湖已缩小了200k㎡。并且由于填湖造陆、城市化和全球气候变化等多种原因,东湖的面积将在未来20年中继续缩小30%。湖泊对都市的多种功能也随着面积的消减不断削弱。              
From 1960 to 2020, the largest natural lake in Chinese cities has shrunk by 200 sqkm. And due to various causes such as lake reclamation, urbanization and global climate change, the area of the East Lake will continue to shrink by 30 percent in the next 20 years. On the other hand, the average temperature of Wuhan has been rising over the past 60 years, making it one of the most scorching cities in China.

场地调研-中国最大的城中湖
Site Investigation-The Largest Natural Lake in Chinese Cities
湖泊面积的减小进一步加剧了城市热岛效应,曾经的“江城”现在却变成了“火炉”。基于这一现象,2030年的湖中城市,将不仅是人类追寻丰富的人居体验的垂直都市,而且是解决能源危机的垂直工厂,应对自然变化的垂直湖泊。它将是一个探索之塔,建立跨越地壳、水层和空气层的城市新秩序。
The decrease of the lake area further intensifies the tropical island effect, What was once the “Lake City” has become a “Scorching Furnace”. Based on this, the city on the lake in 2030, will not only be a vertical city for urban habitation and experience, but also a vertical factory for energy crisis, a vertical lake for natural changes. It will be a Probing Tower, which establishes a new urban order across the crust layer, water layer, and air layer.



城市策略 - 塔楼核心运作机理
Urban Concept-Core Principle Of The Tower
概念:一种尚在实验阶段的天然气采集科技。受这一科技的启发,我们的探索之塔将围绕一个碳封存系统展开。其核心被分为两个部分:第一部分,下钻系统:多根盐水管道将随着建筑基础深入3000米以下的地层中。在这里,甲烷和热盐水将被地壳压力灌入抽取井。被收集到的物质将在湖面进行分离,获得的甲烷将直接为城市供能,而热盐水则作为交换器的热源。随后,发电厂和空气中的二氧化碳将会被压入冷盐水中,并注入地层储存。湖面基础设施将直接保障塔楼上部功能的运作。第二部分,上升系统:冷却过发电机的湖水将以蒸汽的形式在塔楼中核上升,并在冷却后从塔楼表面缓慢流下,形成垂直湖泊。表面环形的渠道在为塔楼降温的同时还将吸收城市热辐射。这一整套系统能够实现正能量循环、零水循环和负碳循环。能量会不断的被产生,碳会不断的被储存,而水,则取之于湖,还之于湖。
Concept: Probing Tower. Inspired by an experimental petroleum technology, a carbon sequestration system is designed for the Probing Tower. This system has two main parts. Part one: Drilling system, Multiple saline pipelines will follow the building foundation down to the depth of 3,000 meters. Here, methane and hot saline will be forced to the pumping well by the crust pressure. Part two: Raising system, The steam from the power generator will rise in the tower core, As it cools, it streams down from the tower's surface, creating a vertical lake. The spiral watercourse on the surface will cool the tower and absorb urban thermal radiation. This system can realize the positive energy cycle, zero water cycle and negative carbon cycle. Which means the energy will be continuously produced, but the carbon will be reduced, However, the water is taken from the lake and fully returned to the lake.

未来展望-水上都市
Prospect: Aquatic City
独立的体系,并不代表成为隔绝的孤岛。空中和水上交通将是不破坏原有湖泊的最优交通方式。而湖中多座塔楼的联动,将为周边陆地街区供电并减小城市碳排放。这将是未来应对海平面上涨问题的全球性实验,为陆地消亡的未来人类社会,提供最后的方舟。
An independent system does not mean that it will become an isolated island. Air and water transportation will be the best means without affecting the existing lake. And the linkage of several Probing Towers, will power the surrounding inland blocks and reduce the carbon emissions of Wuhan. This will be a global experiment in dealing with rising sea levels in the future, providing the final Noah’s Ark for the future society which the land is disappearing.
