solar impulse 2
It will go down in the annals of aviation: A round-the-world flight without a drop of fuel. That was the amazing achievement
The flight of Solar Impulse 2 is a huge achievement for clean energy.
No fuel needed for this epic journey.
The pilots used no fuel to complete the epic trip.
Just over a year ago, in March 2015, two Swiss engineers launched their round-the-world flight on a solar-powered airplane: Solar Impulse 2. The two men, André Borschberg and Bertrand Piccard, designed the single-pilot plane, which began its odyssey in Abu Dhabi, and they alternate laps. The longest lap so far was crossing the Pacific from Hawaii: three days!
A solar-powered, single-pilot airplane just made aviation (and renewable energy) history, completing the 4,000-mile journey
Aviation history is in the making -- no fossil fuels necessary. Solar flight may seem slow, expensive, and downright impractical
