Photo: AHMED JADALLAH Dubai: Two Swiss pilots attempting the first flight around the world in a solar-powered plane began the maiden leg of their voyage on Monday, the mission's official website said. Solar Impulse 2 took off from Abu Dhabi in the United Arab Emirates en route to the Omani capital Muscat at the start of a five-month journey of 35,000 km organised to focus the world's attention on sustainable energy. "Solar Impulse wants to mobilise public enthusiasm in favour of technologies that will allow decreased dependence on fossil fuels, and induce positive emotions about renewable energies," said the mission website, which maps out the plane's location and broadcasts audio from the cockpit in real time. Made from light-weight carbon fibre, the plane is only as heavy a family car (2300 kilograms) and but has a wingspan as wide as the largest passenger airliner. Its journey will span approximately 25 flight days broken up into 12 legs at speeds between 50 and 100 km per hour. Studies, design and construction took 12 years and a first version of the craft rolled out in 2009 broke records for heights and distances travelled by a manned solar plane. The flight will make stopovers in India, Myanmar and China before crossing the Pacific Ocean and flying across the United States and southern Europe to arrive back in Abu Dhabi. "Miracles can be achieved with renewables such as solar power," Swiss pilot Bertrand Piccard, who also made the first non-stop circumnavigation of the globe in a balloon in 1999, said in January. "We want to show we can fly day and night in an aircraft without a drop of fuel," he said. Piccard will be joined by co-pilot Andre Borschberg. The Swiss pilots' idea was initially ridiculed by the aviation industry. Their plane is powered by more than 17,000 solar cells built into its wings which, at 72 metres, are almost as long as those of an Airbus A380 superjumbo. The pilots will only be able to sleep for 20 minutes at a time before having to check the plane's instruments. Companies involved in the project include Bayer AG, Solvay, ABB, Schindler, Omega and Abu Dhabi's Masdar. Reuters

"Solar Impulse želi potaknuti entuzijazam javnosti za tehnologije koje će omogućiti smanjenu ovisnost o fosilnim gorivima i potaknuti pozitivna stajališta prema obnovljivim izvorima ernergije", navodi se na internetskoj stranici misije na kojoj se može pratiti lokacija zrakoplova te audio prijenos iz pilotske kabine u stvarnom vremenu. Zrakoplov je težak poput običnog obiteljskog automobila, odnosno oko 2.300 kilograma, a raspon krila ima poput najvećeg putničkog zrakoplova. Zrakoplov leti uz pomoć sunčeve energije iz 17 tisuća solarnih ploča pričvršćenih na krilima dužine 72 metra. U petomjesečnoj misiji 25 dana će biti letenja podijeljenog u 12 dionica, a letjet će brzinom od 50 do 100 kilometara na sat. Za izradu zrakoplova trebalo je 12 godina od prvih nacrta do konačnog modela. Zrakoplov će slijetati u Indiji, Mijanmaru i Kini prije nego što preleti Tihi ocean, SAD i južnu Europu te se vrati u Abu Dabi. "Čuda se mogu postići obnovljivim izvorima energije poput solarne", kazao je švicarski pilot Bertrand Piccard koji je prvi preletio balonom oko svijeta 1999."Želimo pokazati da možemo letjeti danonoćno u zrakoplovu bez kapi goriva". Drugi pilot Andre Borschberg na konferenciji za novinare rekao je da je to "izazov za čovjeka, avantura i motivacija".
