Bertrand Piccard and Andre Borschberg are flying around the world to spread the word about climate change and the danger it imposes.
Now, you might be thinking: “Hold your horses kid! Don’t airplanes make CO2 and make all of this be “situational irony?”” Well now, I’m thinking: “Thanks Mrs. Wiersig (PreAP English teacher who expounds upon the topic of irony)! But you’re wrong. They’re flying the Solar Impulse 2 that’s wingspan is wider than a Boeing 747’s and is powered solely by solar panels (17,000 solar cells to be exact) that cover the structure of it. During the day, the panels power the plane but also charge two lithium ion batteries that fly the craft at night.
“You fly with no fuel, you have clean technology that make the airplane so efficient,” Piccard said, “that only the Sun is enough to keep it airborne day and night.”
