SUNBEAM Prostaff - MARK SLATS & KAI WIEDMER NEW WORLD RECORD

Mark Slats and Kai Wiedmer set off from San Sebastián de La Gomera in the Canary Islands on December 12 with the goal of achieving a two-man world record. After an incredible journey of 32 days, 22 hours, and 13 minutes, they arrived at Nelson’s Dockyard in Antigua, having rowed more than 3,000 miles across the Atlantic Ocean. This remarkable endeavor is part of the Talisker Whisky Atlantic Challenge.


Their boat ‘Maria’ is outfitted with high-efficiency solar panels and the lightest lithium batteries, providing reliable power throughout the challenging 5000 kilometers of rowing.


The TWAC 2020, known as the world’s toughest row, proved to be no exception. As Mark recounted in his blog: “The last days at sea were tough. We faced a lot of rain, high swells, and rough seas, leaving us with less time to sleep because we were soaking wet when we entered our cabin.”


However, all the hardship was worth it in the end. In addition to competing for the race title, they were also dedicated to raising funds for children’s cancer research. Together, they successfully raised €69,686, surpassing their goal of €65,000 by 107%. Isn’t that amazing? Congratulations to Mark and Kai for their tremendous effort in supporting this important cause. We eagerly anticipate their next adventure!

USER PROJECTS - LUNARK: A JOURNEY TO THE MOON

Top view of a solar-powered lunar habitat prototype on snow-covered ground.

THE EXPEDITION

During the next year, two young Danish Space Architects, Sebastian and Karl-Johan, will face the challenge of designing, building, and living in the very first Moon Analogue habitat in the Arctic, Greenland for three months. Isolated and confined in one of the harshest climates on Earth, they will endure -30°C temperatures, hurricane winds, and the threat of hungry polar bears. Over the past year, they’ve established SAGA Space Architects and won several awards for their innovative work. Now, they are embarking on their most ambitious project yet, which incorporates advanced solar panel technology to enhance sustainability in extreme conditions. 


One of the biggest challenges for the habitat is its transportability, both for Greenland and for future Moon missions. By combining the ancient Japanese art of paper folding with the principles of biomimicry, they have developed a lightweight and strong foldable structure. This innovative design aims to utilize high-efficiency solar panels to provide energy in the habitat. The challenge lies in translating origami into thicker panels that can still fold, with the answer possibly found in nature. The final hinge design will be a compliant mechanism that is lightweight, strong, airtight, simple to manufacture, and easy to maintain, making it a perfect fit for marine solar solutions.

THE HABITAT CHALLENGES

Exterior like a tank, the interior like a home. While introducing “hygge” and stimulating internal space, the habitat must face the following arctic and lunar challenges: 


Arctic Climate: Temperatures of -30°C and wind speeds of 90 km/h require a sturdy habitat with heavy insulation. 


Transportable: Shipping materials to the Moon or Greenland is costly. We will develop a unique expanding design that saves space during transport and maximizes space after deployment. 


Solar Energy: The project simulates a mission to the peak of eternal light on the Moon, which shares a similar day-night cycle with the arctic day. We will fully leverage this by integrating high-efficiency solar panels into the skin of the habitat, ensuring it meets all its energy needs through advanced solar panel technology. 


Polar Bears: On the Moon, there is a risk of meteor impacts. In Greenland, you might encounter a curious polar bear weighing 650 kg. The habitat must be robust enough to withstand such challenges. 


Zero Waste Ecosystem: The habitat must leave no trace and recycle as much waste as possible, aligning with marine solar solutions that promote sustainability.

After mission update

From September to November, the habitat was tested on an analog Moon mission near Moriusaq, Greenland, in the high arctic. During this mission, Sebastian Aristotelis and Karl-Johan Sørensen deployed the habitat, which was equipped with high-efficiency solar panels, and lived in it for 60 days in complete isolation. This innovative use of marine solar solutions helped sustain a comfortable living environment during the expedition, even as the habitat endured hurricane-scale winds, snowstorms, and temperatures dropping to -30°C, showcasing the resilience of modern solar panel technology.
