Bertrand Piccard and André Borschberg today unveiled, at Dübendorf airfield close to Zurich, the Solar Impulse HB-SIA, the first aircraft designed to fly both day and night without fossil fuel or pollution. see the video
The presentation of the prototype took place in front of more than 800 persons, including 200 representatives of the international media, and many high-ranking guests among them H.S.H. Albert II of Monaco, the Swiss Minister of Energy and Environment, the CEOs of Solvay, Omega and Deutsche Bank and the CEO of the International Air Transport Association (IATA).
The press conference was also relayed live on Internet and was followed by journalists all around the world. 60 media representatives gathered in Beijing and followed the conference in front of giant screen, in simultaneous translation for the occasion.
A revolutionary airplane
Bertrand Piccard and André Borschberg first retraced the history of the project since it was launched in 2003. 6 years of intense work, calculations, simulations and tests were needed by the 70-person team to complete this totally unprecedented aircraft: with the wingspan of a Boeing 747-400 and the weight of an average family car (1600 kg), never has such a large craft been built with such low weight. Over 12,000 solar cells mounted onto the wing will supply renewable energy to the four electric motors with a maximum power of 10 HP each. During the day they will also charge the lithium-polymer batteries (400 kg), which will permit the HB-SIA to fly through the night.
The HB-SIA is the first prototype of the Solar Impulse project. Its mission is to demonstrate the feasibility of a complete day-night-day cycle propelled solely by solar energy. After fine-tuning on the ground, the aircraft should make its first test flights between now and the end of 2009, first of all at Dübendorf airport (canton of Zurich) and then from Payerne air base (canton of Vaud). A first complete night flight is programmed for 2010 and will take place over Switzerland.
The results from the HB-SIA and their analysis will serve to develop and build a second aircraft, the HB-SIB for circumnavigating the word in five stages, each lasting several days, in 2012.
A supporters program
In response to demands from many enthusiasts, Solar Impulse announced today a program specially reserved for people wanting to participate in the adventure and to express their support of the project’s philosophy. Supporters can enroll on www.solarimpulse.com to receive news in real time, to adopt a solar cell on the wing, reserve a VIP visit at the Solar Impulse base, or place their names on the aircraft’s fuselage.
A symbol for promoting renewable energies
In a world dominated by fossil fuels, and given the urgent need to find sustainable solutions, the Solar Impulse project sets out to demonstrate the potential of renewable energies and to promote their use. It is also a symbol of the energy savings that can be accomplished using new technologies. The pioneering spirit which enabled man to conquer the planet and space in the 20th century should today allow us to find solutions to reduce our dependence on oil, not by reducing mobility and personal comfort, but by creating dreams, hope and enthusiasm.
