Solar Impulse 2: showing efficiency of solar energy

The world’s first solar powered plane is going on round-the-world tour and it started its journey from Abu Dhabi.

The travel journey is about 35,000 kilometres covering 12 countries which include India, Myanmar, China, Hawaii, and New York and will finish the journey to where it started i.e. Abu Dhabi.
The aim of this journey is to highlight the importance of renewable energy. This project started in the year 2002 and the cost estimated is more than $100 million.

The amazing fact about this plane is that it has not a single drop of fossil fuel. When it comes to energy this single-seat plane has 17,248 ultra-efficient solar cells that are capable of transferring solar energy to four electrical motors which finally power the plane’s propellers. The power comes by recharging the four polymer batteries which is done at night.

Solar Impulse 2 weighs 2,300 kilograms which is similar to a mid-sized truck. It is lighter than the empty Boeing 747 which weighs around 180,000 kilograms. The plane’s speed is 45 kph (28 mph) which can be doubled at the daytime when the sunrays are at its peak. Solar Impulse 2 is flying in an altitude of around 28,000 feet (8,500 meters) in the daytime and at the night dip at around 5,000 feet when flying above the oceans.

The pilot of the plane is Bertrand Piccard and the co-pilot is Andre Borschberg. The pilots wear Goggles which provides a flash light to awake them. For the safety there are Armbands that are placed under their suits that will open in case of emergency.
