What motivated Piccard to fly around the world in a solar-powered plane?
In Bertrand Piccard’s family, there is a tradition of being
first. His grandfather, Auguste, was the first person to
ride a balloon into the stratosphere. His father, Jacques,
was the first to reach the Earth’s deepest point, the
Pacific’s Mariana Trench. And in 1999, Piccard
completed the first non-stop, around-the-world balloon
flight. This feat, plus an environmentally conscious
approach to innovation, spurred the renowned Swiss
adventurer to dream of circumnavigating the globe in a
plane that uses no fuel. The result is the Solar Impulse
2, an aircraft equipped with more than 17,000 solar
cells. Thanks to lithium batteries that efficiently store
energy reserves, it is the first solar-powered plane that
can fly through the night. “If we want to solve our
pollution and energy problems,” says Piccard, a
psychiatrist by training, “we need to increase our energy
efficiency and focus on clean technologies. Solar
Impulse 2 is really a way to show that those
technologies are mature.”
