SYSTEMS: Dreamliners, A380s and beginnings of sub-orbital space flight are pushing the boundaries of cutting edge technology in travel, but a more sedate and clean form of transport is also making its mark. A solar powered flight has recently completed the first stage of its journey across the US, spending a fair amount of its time flying at night. READ MORE on LiveScience.
Solar Impulse is the first aircraft capable of flying day and night without using any fuel. The plane relies solely on its solar panels and onboard batteries for power.
During the recent flight, the aircraft was expected to reach a cruising altitude of 21,000 feet (6,400 meters).
Solar Impulse founders Bertrand Piccard and André Borschberg alternated piloting the single-seater plane over the five legs of the journey. Piccard was at the controls for today's takeoff from California. Piccard took the first leg of the flight.
The aircraft landed safely at Phoenix Skyharbor Airport at 1.30am local time.
