solar Impulse is not the first solar airplane, but it is the first to fly day and night, without any fuel, only using energy stored in its batteries. It is also the first to have achieved an oceanic crossing: 5 days and nights from Nagoya, Japan, to Kalaeloa, Hawaii. Behind Solar Impulse’s achievements, there is always the same goal: show that if an airplane can fly several days and nights in a row with no fuel, then clean technologies can be used on the ground to reduce our energy consumption, and create profit and jobs.
