There is no doubt an outstanding event in the history of aviation. Piloted by Swiss Andre Borschberg, a single-seat plane landed on a small airfield in the suburbs of Honolulu in Hawaii on Friday.
The peculiarity of this flight is well known: the Solar Impulse 2 aircraft was equipped with solar-powered engines. The non-stop flight from the Japanese city of Nagoya took almost 118 hours, almost 50 hours higher than the previous record of nine years ago, held by the American Steve Fossett, who, by the way, flew in a jet plane.
Solar Impulse 2 is powered by 17, 000 solar panels. The energy accumulated by them was enough even for the night. The initiators of this project, without any guarantees, took a serious risk, but their risk was justified. Humanity has gained a unique experience of using renewable energy in the creation of a new generation of aviation.
The weight of the "solar" aircraft, made of carbon fiber, is about 2268 kg, and the speed is 45 km / h. A minibus or medium truck weighs about the same. The cost of the project amounted to more than $ 100 million. However, it is still too early to talk about the mass construction of aircraft on solar batteries. While we can talk about the continuation of research.
