The history of Solar Impulse project

The vision and the team behind Solar Impulse

Solar Impulse is a long-range experimental solar-powered aircraft project that started in 2003. The project was initiated by two Swiss adventurers, Bertrand Piccard and André Borschberg, who wanted to demonstrate the potential of renewable energy for aviation. Piccard is a psychiatrist and balloonist who co-piloted the first balloon to circle the world non-stop in 1999. Borschberg is an engineer and businessman who has a passion for flying and innovation. Together, they formed a team of experts, sponsors, and partners to make their vision a reality.

The challenges and achievements of Solar Impulse 1

The first prototype of Solar Impulse plane, often referred to as Solar Impulse 1, was designed to remain airborne up to 36 hours. It had a wingspan of 63.4 meters (208 feet) and a weight of 1,600 kilograms (3,500 pounds). It was powered by four electric motors and more than 11,000 solar cells that covered its wings. It conducted its first test flight in December 2009. In July 2010, it flew an entire diurnal solar cycle, including nearly nine hours of night flying, in a 26-hour flight. This was the first time that a solar-powered plane flew through the night. In 2012, Piccard and Borschberg completed successful solar-powered flights from Switzerland to Spain and then Morocco.

The world record of Solar Impulse 2

A second aircraft, completed in 2014 and named Solar Impulse 2, carried more solar cells and more powerful motors, among other improvements. It had a wingspan of 71.9 meters (236 feet) and a weight of 2,300 kilograms (5,100 pounds). It was capable of flying indefinitely, as long as weather conditions were favorable. On March 9, 2015, Piccard and Borschberg began to circumnavigate the globe with Solar Impulse 2, departing from Abu Dhabi in the United Arab Emirates. The aircraft was scheduled to return to Abu Dhabi in August 2015 after a multi-stage journey around the world. However, the plane faced several technical and meteorological challenges along the way, such as overheating batteries, strong winds, and monsoon seasons. The most difficult leg of the journey was from Japan to Hawaii, which lasted for 117 hours and 52 minutes, setting a new world record for the longest solo flight in history. The plane finally completed its round-the-world trip on July 26, 2016, after flying more than 40,000 kilometers (25,000 miles) in 17 stages and 23 days of flight time.

The features and benefits of Solar Impulse plane

The design and technology of Solar Impulse plane

Solar Impulse plane is a single-seated monoplane that uses photovoltaic cells to convert sunlight into electricity. The electricity is stored in lithium polymer batteries that power the propellers and the systems on board. The plane has a carbon fiber structure that makes it lightweight and resistant. The plane also has a sophisticated energy management system that optimizes the energy flow between the solar cells, the batteries, and the motors. The plane has a low cruising speed of about 70 kilometers per hour (43 miles per hour) and a maximum altitude of about 9,000 meters (29,500 feet). The plane can fly day and night, but it needs clear skies and calm winds to take off and land safely.

The environmental and social impact of Solar Impulse plane

Solar Impulse plane is more than just a technological achievement. It is also a symbol of hope and inspiration for a cleaner and more sustainable future. The plane demonstrates that renewable energy can power long-distance flights without emitting any greenhouse gases or noise pollution. The plane also shows that human ingenuity and perseverance can overcome seemingly impossible challenges. The project aims to raise awareness and support for clean technologies that can reduce the environmental impact of human activities. The project also educates and empowers people to take action for a better world.

The future of Solar Impulse project

The legacy and lessons of Solar Impulse plane

Solar Impulse plane has left a lasting legacy and valuable lessons for the aviation industry and the society at large. The plane has proven that solar power can be a viable alternative to fossil fuels for aviation. The plane has also shown that innovation and exploration can lead to breakthroughs and discoveries. The project has created a global community of supporters, partners, and media outlets that have followed and shared its journey. The project has also generated scientific data and insights that can be used for further research and development.

The next steps and goals of Solar Impulse project

The Solar Impulse project is not over yet. The project team has launched several initiatives to continue its mission and vision. One of them is the Solar Impulse Foundation, which aims to identify and promote 1,000 solutions that can protect the environment while creating economic opportunities. Another one is Skydweller Aero, a company that is developing autonomous unmanned aerial vehicles capable of continuous flight using solar power. The company plans to use the Solar Impulse 2 aircraft for research and development flights, before putting it on permanent display at the Swiss Museum of Transport . The project team also continues to share its experience and knowledge through conferences, books, documentaries, and podcasts.


Solar Impulse plane is an amazing example of how solar power can revolutionize aviation and inspire people to take action for a greener planet. The project has achieved a historic feat by flying around the world without using any fuel. The project has also faced many challenges and overcome them with courage and creativity. The project has not only advanced the technology of solar-powered aircraft, but also raised awareness and support for clean technologies in general.
