Scientists developed the first ever solar powered flight in - GED Prep
Question
Scientists developed the first ever solar powered flight in 2012. The flight took 19 hour cruising at a speed of 71km/h from the Minnesota to Canada. This speed was too low compared to the commercial cruising speed of 917km/h.
The plane has 4 motors that are powered by 12,000 solar cells. Sun’s photon hits the cells and is absorbed by semiconductors. This ejects electrons from the semiconductors, causing a change in electric PE. This creates electricity for powering the motors.
A t day time, the planes climbs the atmosphere to an altitude of 8500m using the motors while at night, the plane converts its PE gained during the day into KE. At 1600m above the ground, the plane’s battery powers the motors to ensure safe landing.
Which is the primary source of energy for this plane?

Explanation
The plane relies on solar energy that is harnessed by the 12,000 solar cells places at the top of the plane’s wings. These solar convert sunlight into electric current.
