Raphal Domjan a Swiss entrepreneur and aviator, but perhaps the most congenial of the explorer definitions. A few years ago he had traveled around the world aboard a trimaran powered exclusively by solar energy. A sort of fixed one for the sun and energy saving, which conditioned Domjan’s choices. Today a new challenge awaits you, which has already been discussed in recent years. Now, for the SolarStratos project, it has entered more than ever and should take off in 2022. As the name implies, it is a solar powered aircraft. Plane with which will have to reach the altitude of 60,000 feet (almost 20,000 meters), so as to get to fly in the stratosphere.

The SolarStratos weighs 450 kg and just over 8 meters long. While the solar cells that cover the aircraft have a total area of ​​over 70 square meters. The energy obtained through these cells is then stored in a lithium ion battery. The electric motor generates 43 horsepower at 2200 rpm. The plane is not pressurized, therefore Raphal Domjan will be equipped with oxygen and a space suit. Everything you need to fly at an altitude that allows you to see the curvature of the Earth. To get to that altitude it will take two hours to reach the area the layer of atmosphere concerned, 15 minutes of flight in the stratosphere and then three hours for the descent.

The maiden voyage scheduled for 2022. Be the forerunner of a project that wants to offer the possibility of a similar experience for private passengers and scientists. The intent is also to feed the image of the SolarPlanet Foundation of Domjan, which is committed to promoting solar energy to combat climate change.
