The Solar Impulse 2, a plane that is circumnavigating the globe without a drop of fuel, is making Phoenix one of its 12 stops around the world.
The aircraft’s pilots say they are trying to change the world by flying around it in a plane powered by the sun’s energy.
Their message is that if the Solar Impulse 2, with a weight equal to a midsize car’s and a wing span equal to a 747’s, can travel 22,000 miles without fuel, then so can many machines.
“We believe that renewable energies are a source of social cohesion, prosperity and peace,” Solar Impulse 2 pilots and co-founders Bertrand Piccard and Andre Borschberg said in a joint statement.
