Bertrand Piccard is no conventional environmental activist -- he hopes to raise awareness about the potential of renewable energy by flying a solar-powered aircraft around the world.(AFP) - Bertrand Piccard is no conventional environmental activist - he hopes to raise awareness about the potential of renewable energy by flying a solar-powered aircraft around the world. "What we want to do is to fly day and night to show that, with renewable energies, you can have unlimited duration of flight, no restriction," Piccard told AFP at the World Future Energy Summit in Abu Dhabi, where he had a booth to promote his venture. The 51-year-old Swiss psychiatrist plans to fly his one-of-kind "Solar Impulse" around the world over 20 to 25 days, traveling at an average of 70 kilometres (43 miles) an hour. He will split the flying time with Andre Borschberg, a former Swiss fighter pilot. "We believe that if an airplane can fly around the world with no fuel, nobody can say after that it's impossible to do it for cars, for heating systems, for air-conditioning, for computers and so on," he said. The prototype of Solar Impulse made its first test flight near Zurich in December. The plane is made of carbon fibre, with solar panels along the top of its roughly 64-metre (209-foot) wingspan. The aim is for the solar panels to absorb energy to power the aircraft during the day, and at the same time store energy in lithium polymer batteries to run the engines at night. After aircraft manufacturers said Piccard's specifications would be impossible to meet, he turned to a racing yacht manufacturer to build the airframe. "They did not know it's impossible, so they did it," he said. The plane is powered by four electric engines, each making a maximum of 10 horsepower. Piccard said that, despite having a wingspan close to that of an Airbus A340, Solar Impulse weighs only 1,600 kilogrammes (3,500 pounds). Asked what led him to try this unorthodox method of promoting renewable energy, Piccard pointed to his family history. "I come from a family of explorers, who always had a lot of concern for the environment and for natural resources," he said. "My grandfather was the first man to explore the stratosphere, to climb above the atmosphere (in a balloon) ... and my father made in 1960 the deepest dive ever in a submarine," he said. - Lindbergh's flight with no fuel - Piccard has already demonstrated a penchant for adventure. In 1999, he and Briton Brian Jones became the first men to complete a non-stop flight around the globe in a hot-air balloon. That flight "gave me the fame to ... do useful things," Piccard said, including finding sponsors, money and support for his current project. The project, which will cost a total of 70 million euros (100 million dollars), has been underway for around seven years and still has a way to go. The attempted flight around the world won't take place until 2012 or 2013. This year, the aircraft will undergo high-altitude testing, and will also be tested in daytime and nighttime flight. If that goes well, the prototype will either be modified or a new one built for a trans-Atlantic flight. "We have to reproduce Lindbergh's flight with no fuel," Piccard said, referring to Charles Lindbergh, the first man to fly solo non-stop across the Atlantic Ocean. The one-man aircraft will land at different points during the flight around the world so the pilots can switch off, Piccard said. In addition to the switch, the landings will be an opportunity "to present the technology of this airplane, to encourage people to use (the technology) also, for their daily life," he said. For Piccard, the Solar Impulse project is a new, positive tack in promoting renewable energy and conservation. "I was in Copenhagen (for the recent climate change conference), and I see people are fed up with the alarmists, the catastrophists," he said. "People need solutions, not problems. So we have to demonstrate the solutions. We have to show that it's possible to do great things." And aviation, Piccard said, is "a good vector to push messages." Reuse content

Zrakoplov na solarni pogon sletio je u Maroko i zaključio svoj prvi interkontinentalni let na solarnu energiju kako bi pokazao mogućnosti zračnog putovanja bez zagađivanja Zrakoplov Solar Impulse poletio je u utorak prije zore iz Madrida i sletio u međunarodnu zračnu luku u Rabatu nakon 19 sati leta. Kratko vrijeme prije no što je pilot Bertrand Piccard sletio u Rabat, suosnivač projekta i pilot Andre Borschberg je izjavio da je zrakoplov dokazao svoju održivost. 'Zrakoplov sada može letjeti danju i noću. To je tehnologija kojoj možemo vjerovati', rekao je novinarima. Piccarda su po izlasku iz zrakoplova dočekali Borshberg i Mustafa Bakuri, čelnik marokanske agencije za solarnu energiju. Eksperimentalni zrakoplov na solarni pogon Solar Impulse poletio je u 24. svibnja iz zračne luke u Payerneu na zapadu Švicarske prema Maroku preko Madrida i preletio oko 2000 kilometara bez kapi goriva. Zrakoplov ima raspon krila poput Airbusa A340 (63,40 metara) a ne teži više od automobila (1600 kg). Prethodni prototip zrakoplova Solar Impulse s pogonom isključivo na sunčevu energiju obavio je ljeti 2011. niz letova po Europi. Projekt je potaknuo švicarski graditelj Piccard, izumitelj koji potječe iz obitelji istraživača i znanstvenika. Zrakoplov ima četiri električna motora od 10 KS svaki i leti poput nebeskog skutera prosječnom brzinom od 70 km/sat. Njegova su krila prekrivena s gotovo 12.000 solarnih ćelija, koje opskrbljuju četiri elektromotora i omogućuju punjenje litijevih baterija od 400 kg. Ova ekspedicija koja prvi put prelazi Sredozemlje, zapravo je posljednji pokus pred pokušaj leta oko svijeta na solarni pogon 2014., koji će se obaviti drugim zrakoplovom a njegova je gradnja već počela. Taj novi zrakoplov bit će većih dimenzija i trebao bi obletjeti svijet u pet etapa. Projekt Solar Impulse započeo je 2003. s desetgodišnjim proračunom od 90 milijuna eura. Solar Impulse još nije prijetnja komercijalnim zrakoplovima koji lako dostižu i deset puta veće brzine. Voditelji projekta priznaju da je veliki izazov bio uskladiti spori zrakoplov s komercijalnim sustavom zračnog prometa. - Sviđa vam se članak?
