Solar impulse 2 is closer to the round-the-world flight
Solar impulse 2 (Si2) is a project that has set out to achieve the first round-the-world solar flight, powered by the sun and with no fuel or polluting emissions. The project wants to demonstrate the reach and capabilities of renewable clean energies.
This adventure is lead by Swiss psychiatrist and aeronaut Bertrand Piccard and engineer and businessman André Borschberg. The Piccard family has a long tradition on exploration, scientific development and protection of the environment.
The solar-powered airplane landed in Mountain View, in the Silicon Valley after a 62-hour flight from Hawaii.
Since their journey in Si2 began in March 2015 departing from Abu Dhabi, the pilots have made stops in Oman, Myanmar, China, Japan and Hawaii.
With some problems along the way like damage in the battery system or faced to unfavorable weather or a damaged wing the journey has been delayed, but has achieved all its expectations according to their website.
The plane's wings have 17,000 solar cells. They power propellers and charge batteries which overnight give the energy needed to fly. They're wider than the wings of a Boeing 747.More so, the ideal flight speed is 28mph that can double during daytime.
Before crossing the Atlantic Ocean to Europe or Northern Africa before finalizing their journey in Abu Dhabi the Si2 will make two more stops in the US. They're planned to be in the Mid USA and New York.
Besides the implications of flying a solar-powered airplane to show the importance of renewable sources of energy, Si2 is also a challenge for human endurance.
As told by the pilots to The Associated Press on Sunday, they use self hypnosis, meditation and yoga to stay alert and cope with the circumstances of flying this airplane.
"It's very active, there are a lot of things to do, but you can nevertheless enjoy it, " said Piccard to the AP.
Despite this type of flying is not commercially practical because of the constraints of the airplane and travel time, it is in fact showing how a better quality of life based on clean technologies and renewable energy is possible.
"Adventure in the 21st Century consists of applying human creativity and the pioneering spirit to developing a quality of life which present and future generations have a right to expect," said Piccard in 2004, when the project was in its initial phase.
