Solar-Powered Plane Takes to the Skies - 8th April 2010

A solar-powered plane has successfully made its first test flight over Switzerland.

The prototype plane Solar Impulse has 12,000 solar cells built into its wings, which are as wide as that of a 747.

The solar cells power four electric motors and propellers. The plane weighs roughly the same as a mid-size car and travels at about the same speed as a bicycle.

Taking to the skies for the first time yesterday, the plane cruised for 87 minutes, reaching a top speed of 45 kilometers per hour.

Creator Betrand Piccard will build a new solar plane, which he plans to fly around the world in 2012.

Mr Piccard completed the first ever non-stop, round-the-world hot air balloon flight in 1999.
