Solar Impulse 2 Completes Epoch-making Journey Across Four Continents, Proving Potential of Renewable Energy

The Solar Impulse 2 has dramatically concluded an astonishing global odyssey, marking it as the first aircraft to ever complete a round-the-world voyage without a single drop of fuel. This remarkable feat saw the sun-powered aircraft traverse four continents, spanning a staggering 24,800 miles (approximately 38,600 Km), over a period of 50 days. This groundbreaking achievement was celebrated with a proud landing in Abu Dhabi yesterday, met with ecstatic ovation and marking an undeniable testament to the game-changing potential of renewable energy sources, particularly as global concerns about climate change continue to escalate.

The Solar Impulse 2 plane, powered solely by solar energy, concluded its final leg of the journey this weekend. Having soared above 16 separate international regions, it took off from Cairo and made its last touchdown in the United Arab Emirates’ capital, as can be witnessed in the flight path illustrated by The Guardian.

Throughout the journey, the day’s sunlight was harnessed to charge the plane’s power source, facilitating the barrier-breaking bout piloted by Swiss aviators Bertrand Piccard and Andre Borschberg. This innovative resource management system enabled the duo to climb to heights of 29,000 feet during daylight hours and descend to approximately 5,000 feet during the night to conserve energy. Despite boasting an average travel speed of around 30 miles per hour (roughly 48km per hour), the Solar Impulse 2 has displayed its potential by exceeding that speed and reaching up to 46 miles per hour (approximately 74km per hour) during high-power situations. Whilst this is currently not a competitive speed for commercial air travel, the accomplishment signals a significant stepping stone into a future of solar-powered aviation.

Upon landing in Abu Dhabi, the effervescent Bertrand Piccard addressed the crowd of enthusiasts and proclaimed, “The future is clean. The future is you. The future is now. Let’s take it further.” These empowering words encapsulated the spirit of this monumental endeavour with a forward-looking perspective.

Even Mr. Ban Ki-moon, the then United Nations Secretary General, extended his words of encouragement and admiration to these intrepid pilots, who endured challenging conditions throughout their lengthy flight. Due to the Solar Impulse 2’s unheated and unpressurised cabin, the pilots had to contend with harsh conditions, relying on brief naps while grappling with the practical needs of nature without shifting from their seats. Their dedicated commitment and perseverance have undoubtedly reinforced the powerful message carried by their solar-driven journey.
