The Solar Impulse 2 (SI2) — the first solar-powered plane to go around world — landed in India in Ahmedabad on March 11. A 35,000-kilometre journey with the purpose of spreading the message of clean technology began its journey in Abu Dhabi on March 9. Over its 25-day journey around the globe, the plane will make stopovers in Myanmar and China. It will then fly over the Pacific Ocean, across the United States and Southern Europe, making a total of 12 stopovers before returning to Abu Dhabi by late July. Following the first version of the aircraft, which came out in 2009, the SI2 is fuel-free and is powered by over 17,000 solar cells on its wings that recharge its batteries and enable it to fly. The single-seater aircraft weighs 2,300 kg — the weight of a family car — and will travel at speeds of 50 kmph to 100 kmph. Designed and constructed over the past 12 years, the Solar Impulse 2 is grabbing eyeballs as it renews hope for clean and renewable energy.
