This Breakthrough Machine Could Accelerate Coral Reef Recovery

The new Formula 1 season opened last weekend with the Australian Grand Prix in Melbourne, following a strong year for McLaren Racing in which driver Lando Norris secured his first F1 World Drivers’ Championship.

Alongside the start of the championship, attention has also turned to a very different race taking place off the track. At the Grand Prix, McLaren Racing and the Great Barrier Reef Foundation revealed a new machine designed to accelerate coral restoration, bringing motorsport engineering into reef recovery. Two years after engineers and marine scientists began working together, the project has now moved from prototype development into real-world field testing.

How McLaren Racing Is Working To Save The Great Barrier Reef

Known as Machine One, the semi-automated system has been developed to address one of the most persistent constraints in reef restoration, and that’s speed. The machine assembles coral ‘seeding’ devices that hold young corals before they are returned to damaged areas of the reef, a process that currently takes up to 90 seconds by hand, but can be completed in as little as ten seconds.

The link between motorsport and marine science lies largely in timing as each spring, over just a few nights, corals release millions of tiny reproductive bundles into the ocean in a natural event known as spawning. Scientists collect these bundles, grow them in controlled conditions and then settle baby corals onto specially designed cradles before placing them back onto the reef.

The science has already shown encouraging results, particularly when using corals with a higher tolerance to warming ocean temperatures. The difficulty though, has always been scale as assembling each cradle is a manual and labour-intensive task, and when the narrow spawning window closes, the opportunity to deploy the corals in significant numbers closes with it. Cue Machine One, which has been engineered through McLaren’s Accelerator Programme with the aim of changing that. Early modelling suggests the system could assemble up to 100,000 coral seeding devices each week, increasing annual coral planting from around 100,000 to potentially one million, while also reducing costs.

For McLaren, the thinking derives from its same performance mindset. Kim Wilson, Sustainability Director at McLaren Racing, explains: ‘In racing, marginal gains add up and drive high performance, and we’re applying that same philosophy to reef restoration. Here, every second saved doesn’t just increase performance, but accelerates the scale, delivery and capacity for innovative engineering solutions and problem solving to help us protect and restore this vital ecosystem.’

The urgency is clear, and the Great Barrier Reef has experienced repeated mass bleaching events in recent years as ocean temperatures rise. While restoration alone cannot counter climate change, improving the speed and scale of coral planting could help strengthen reef resilience during what scientists describe as a critical period. Anna Marsden, Managing Director of the Great Barrier Reef Foundation, says the scale of the challenge remains considerable. ‘We are in a race against time, working at a scale that can feel impossible. But this partnership is proving world class engineering can help close that gap, and that delivering restoration at the speed and scale the reef demands is still possible.’

Following factory testing, Machine One will now be transported to Townsville for trials at the National Sea Simulator, where engineers and marine scientists will test the system under reef conditions ahead of this year’s coral spawning season, and as with an F1 car, the technology will be assessed and refined through testing.

Dr Cedric Robillot, Executive Director of the Reef Restoration and Adaptation Program, says the upcoming trials will be crucial in understanding the system’s potential. ‘Innovation alone is not enough, Machine One must stand up to real-world testing. These field trials will allow us to assess performance, understand limitations and refine the system before broader application. If the data supports it, this approach will represent a major step forward in how we deliver restoration globally and at scale.’ If successful, the technology could eventually be deployed across reefs worldwide, which support around a quarter of all marine life and underpin the livelihoods of close to one billion people globally.

The collaboration also reflects a bigger change within the sport, which has a sustainability strategy aimed at reaching net-zero carbon emissions by 2030. As the sport introduces sustainable fuels and reduces emissions across its operations, teams are increasingly exploring how their engineering expertise might contribute to environmental solutions off the track.
