Pesawat Terbang Bertenaga Surya pertama di Dunia

Pesawat terbang yang menggunakan tenaga surya (matahari) melintas di atas jembatan Golden Gate, California, dalam misi melintasi Amerika, Selasa (23/4/2013). Tahun lalu, pesawat buatan ilmuwan Swiss ini sukses terbang dari Spanyol ke Maroko. Tahu berapa kecepatan pesawat ini? Hanya 70km/jam. Pesawat "Solar Impulse" memiliki panjang 21, 85 meter dengan lebar sayap 63,4 meter atau setara dengan pesawat Airbus A340. Agar terbang, pesawat dari serat karbon ini menggunakan 12 ribu panel surya di kedua sayapnya sebagai sumber tenaga empat sepeda motor listrik
Ambitious: The team behind the Solar Impulse are planning to attempt a flight across the U.S. in the solar energy-powered plane

Record: The team are hoping to complete a round the world flight in the solar-powered plane, seen in a hangar in California last week, by 2015

Solar-powered: The Solar Impulse HB-SIA is powered by four electric motors and designed to fly day and night by saving surplus energy from its solar cells in high-performance batteries

Tuesday's flight was a technical test run to prepare for a planned cross-country trip beginning in early May

The lightweight plane, which has a wingspan of 208 feet, flew at about 3,000 feet in the air during Tuesday's test flight 

The delicate, single-seat plane cruises around 40 mph and can't fly through clouds

Impressive feat: Considered the world's most advanced sun-powered plane, the Solar Impulse took off from Moffett Field in Mountain View at first light for a two-hour practice run in advance of a planned multi-city, cross-country tour
