These smart homes are designed to adapt to rising sea levels by mimicking a pufferfish!

Puffer Village is a system of smart homes with built-in architectural technology that allows them to adapt to changing water levels and stormy weather conditions.

Sajjad Navidi is a 3D visualizer who uses architecture to prepare for impending climate change-related crises. Upon completing their latest rendering, Puffer Village, Navidi prefaces their project, “One of the major future crises of the world is rising sea levels, which could pose a serious threat to human survival.” To combat the threat of rising sea levels, Puffer Village is conceptualized as a small community of smart homes that adapt to changing tides and rising sea levels by mimicking the defense response of pufferfish.

In designing Puffer Village, Navidi looked to areas of the globe that would feel the consequence of sea-level rise sooner than others. Describing the planned location for Puffer Village, Navidi notes, “Ganvie is one of the largest lake villages in Africa in the Benin region. One of the biggest problems for the people of this region is the high sea level.”

As storms sweep the town and tides threaten homes’ foundations, residents of Ganvie have no choice but to face the uncertainty of rising sea levels. Navidi goes on to describe the damaging effects that high tides have on the wooden houses of Ganvie.

Looking to nature, Navidi hoped to find a solution that could adapt to changing water conditions. Finding inspiration in the pufferfish that populate Ganvie’s ​​Lake Nokoué region, Navidi planned out smart homes that would adapt to threatening water and storm conditions the same way pufferfish respond to predatory threats. Describing his findings, Navidi notes, “The biomimetic structure of [the] pufferfish and its strategy [in dealing] with enemies is by inflation with water or air.”

Following periods of research and ideation, Navidi planned a home layout with integrated, automatic inflation and load-bearing smart technology. In its neutral position, each home of Puffer Village remains rooted to the lake’s floor and keeps a flat-roof shape.

Even amidst stormy conditions and high tide, each home of Puffer Village turns into a sort of buoy by filling the home’s bottom compartment with water in order to remain anchored to the lake’s floor.

Navidi also ideated a smart inflation system built into each home of Puffer Village that increases each home’s interior volume by inflating the home’s balloon-skin roof with air. Each home also practices energy efficiency by acquiring the power needed for each smart response system through underwater tidal turbines and photovoltaic panels.

Aquaponics fill out the home’s interior, while solar power is generated from overhead photovoltaic panels and water energy is acquired from underwater tidal turbines.

The home’s layout is inspired by the mating circle created by male pufferfish.

Orbital Marine Power’s latest renewable energy project is a tidal turbine that can provide electricity for 2,000 homes!

Tidal turbines are some of the most efficient renewable energy producers, offering predictability, reliability, and low-cost upkeep (albeit following an expensive construction period). Harnessed by free-floating turbines or ones contained within barrages, tidal energy produces power from ocean surges during the rise and fall of tides. Orbital Marine Power, a renewable technology company, recently launched their very own tidal turbine called O2 off the coast of Orkney, Scotland.

O2 is a 74-meter, free-floating, 2MW tidal turbine that will be able to provide sustainable, renewable energy for the next fifteen years with the potential to fulfill an annual electricity quota for around 2,000 homes across the UK. Stationed in the Orkney Isles, O2’s location was specifically chosen for the powerful tidal currents resulting from the confluence of the Atlantic Ocean and the North Sea. In fact, O2 is anchored in the Fall of Warness, a location known for its high-tidal energy, reaching tidal flow velocities of 3 m/s, or around six knots. Taking advantage of the sea’s perpetual tidal energy, Orbital Marine Power cabled O2 to one of Orkney’s onshore electricity networks to begin collecting and generating renewable energy. In building O2, Orbital Marine Power equipped the vessel with a two-bladed pitching hub, 1 MW nacelle, and a 20m rotor to allow for bidirectional navigation and optimize tidal flow.

Orbital Marine Power is a privately held company that found support in public lenders and various green initiatives from the Scottish government and E.U. to help fund O2’s launch. Michael Matheson, a supporter of O2 and cabinet secretary for Net Zero, Energy and Transport notes, “With our abundant natural resources, expertise and ambition, Scotland is ideally placed to harness the enormous global market for marine energy whilst helping deliver a net-zero economy…The deployment of Orbital Marine Power’s O2, the world’s most powerful tidal turbine, is a proud moment for Scotland and a significant milestone in our journey to net-zero.”

O2 has the potential to generate enough power for 2,000 homes across the UK.

Following a lengthy and expensive construction process, O2 was built to harness energy from tides and produce power.

The 74-meter long turbine features a two-bladed pitching hub, 1 MW nacelle, and a 20m rotor.

Dynamic power cable connections are located on both ends of the turbine, connecting it to onshore electricity networks.

O2 also comes complete with boarding and loading decks so researchers can delve into the science behind acquiring tidal power.

The tidal turbine is located in the Fall of Warness, a high-tidal energy environment resulting from the confluence of the Atlantic Ocean and the North Sea.

Orkney’s coast is known for high tidal action.
