    On the land, people move by car and trains. On the sky, people move by planes. In the deep sea, people move by... YES, the submersible. It takes about an hour for a regular person to swim 2~4 kilometres, way slower than walking on a flat land. Therefore, innovative transportation methods become crucial for interconnectivity in the deep sea.

    Submersible vehicles would be built with robust materials that can withstand the extreme pressure of the deep sea. To ensure the structural integrity of the submersible in extreme conditions, reinforced alloys, carbon fibre composites and advanced polymers with high strength would be used in constructing the submersible, at the same time ensuring the light weight of the submersible. Submersibles would feature a streamlined shape to reduce resistance and improve manoeuvrability in the water. This design would allow for efficient movement through the deep sea, minimising energy consumption and maximising efficiency. 

    The submersible would employ advanced electric thrusters powered by renewable energy sources, such as the algae-bio fuel. These propulsion systems are silent and does not emit harmful emissions, reducing noise and water pollution. Large, transparent domes will be installed on the sides of the submersible, allowing the passengers to observe the mesmerising marine life during their journeys.


a rough sketch of the submersible

    Since the deep sea is mostly the same everywhere, in every direction, submersibles should be equipped with sophisticated navigation systems. GPS and sonar system would be employed in the submersibles to ensure safe navigation in the deep sea. Life support systems such as oxygen tank, temperature control and carbon dioxide removal system w.    
ould be present in the submersible just in case the hulk of the submersible crashes. These safety measures ensure that in the event of an accident, passengers can safely remain within the submersibles until rescue.

    Deep-sea buildings, instead of conforming to traditional architecture norms, would move with the underwater currents. This is because constructing buildings on the deep sea bed would require enormous resources to stabilise the buildings. The buildings will feature curvilinear from that mimic the contour of the ocean, reducing the resistance to currents and increasing the stability of the building. Therefore, houses in the deep sea is a a camp-van, you sleep beside a mid-ocean ridges, then wake up in the middle of nowhere. 

    To enhance stability of the buildings, they can be anchored to the seabed with flexible cables. While two or more buildings are in the vicinity of each other, enclosed tubes can be connected between the buildings, serving as a hallway for residence in different buildings to pass. These walkways are made of high strength PVC materials, allowing the easy installation and ensuring safe use. 

    While there's no underwater current, the buildings will sway gently with the movement of the water, like seaweed. However, the anti-trembling engineering techniques employed in the buildings will ensure that the residents inside experience a sense of stability. The architectural framework will absorb the forces and pressure exerted on it by the current, minimising vibrations in the interior area.

a simple illustration of buildings in the deep sea

    The vision of human settlement in the deep sea unveils a world where submersible and floating buildings are norm. These submersibles and buildings are designed to withstand high pressures, allowing humans to venture further into the deep sea. As we continue to push the boundaries of exploration, we create a future where the deep sea is a thriving community where humans and marine life coexist in harmony.

      Communication is particularly difficult in the deep sea, as traditional forms of communication, such as radio waves or optical signals, experience significant loss and degradation as they propagate through the water. The absorption of these waves limit their transferrable range and make reliable long-distance communication challenging. The immense water pressure in the deep sea also makes it hard for cables and equipment as they are vulnerable to extreme conditions and predatory animals. Hence, to establish a reliable connection and communication in the deep sea, scientist must push the boundaries of technology.     One approach to deep sea communication is, of course the bioluminescent  signalling. (pardon my obsession with bioluminescent fishes) Drawing inspiration from the mesmerizing bioluminescent displays of deep-sea organisms, engineers could perform genetic engineering on fishes to emit specific light patterns and  colours in response to encoded messages.

       In 30-40 years, advancement in underwater architecture have made it possible for humans to establish settlements beneath the sea. As land resources become increasing limited with the increase in human population worldwide, scientists and researches might propose living under water as a way to expand living space.  This is because the ocean covers 71 percent of the earth's total surface, offering ample room for underwater habitats. Environmentalists agree to this alternatives as the ocean represents a largely untapped resource, and utilising it is a sustainable alternative. Self-sufficient and eco-friendly underwater habitats will be built to reduce the strain on land-based resources such as fossil fuels and non-renewable energy, as well as minimise the carbon footprint associated with traditional construction. deep sea creatures     Since no sunlight can penetrate through the dense water, scientists study bioilluminescent fishes to act as light sources. These fishes can be g

     If you somehow end up in the deepest  part of the world's oceans, Mariana Trench, which is approximately 11 thousands meters under water, the pressure would be roughly equal to having the weight of a Myvi pressing down on every square centimetre of your skin, in every direction. A feeling of isolation and icy coldness will envelop you, as the temperature of water around you is just hovering above freezing point.  exploring the Mariana Trench    Amidst the cold and eerie silence, some faint light flashes from distance. It danced and shimmered, breaking through the darkness like tiny stars. As the light source drew closer in a hasty pace, a school of bioluminescent fish revealed themselves, their bodies aglow with otherworldly radiance.       Imagine a realm so vast and unexplored that it covers over 90% of the Earth's bioshere, but so mysterious that we know more about the surface of the moon than we do about it - the deep sea.  Even until recently, the deep sea was largel
