Solar powered aircraft
Some time ago I wrote about ships powered by solar energy , and the other day this type of energy subdued another type of transport - airplanes.
How do the media write :
“For the first time in history, a solar-powered plane took off into the sky. It was ruled by Swiss Bertrand Picard. The flight lasted two hours and ended successfully. "
The unit itself is in the air:
Top view of the battery:
This miracle is called Solar Impulse. On the official site of the project there is a full description, video and other materials.
Flight video:

Technical characteristics of the device:
Wing Span 80 m
Maximum weight 2 tons.
Average speed of 75 km / h
Maximum height of 12,000 m
Temperature overboard from + 80 to - 60 C
Wing
The wing span of the Solar Impulse is equal to the wing span of the Airbus a-380 - 80 m. This length is necessary first of all to ensure sufficient coverage of photovoltaic plates that absorb sunlight (to lift 10 kg of weight into the air, you need a 1m2 battery). The plates themselves are made of silicon, have a thickness of 130 microns and are flexible enough to withstand stress and strain.
Cabin
Almost 100% made of puff carbon. Only one person can be here. It will create all the conditions for comfortable work at an altitude of up to 12,000 m, even under adverse climatic conditions - oxygen is distributed evenly, and carbon dioxide, gas and humidity emitted by man are taken overboard.
Engines
The energy received from the sun during daylight is not fully consumed. Part of it is accumulated in lithium batteries that power four independent engines at night. ( source )

Solar energy is not the only alternative source of energy tested recently.
So Richard Branson’s Virgin Atlantic company was raising its plane with one tank full of biofuel from vegetable fats, and Continental Airlines, the same Boeing 747, as Branson’s company took off into the air on biofuel from algae .
Another type of fuel is hydrogen, in my opinion it could be the best alternative to modern fuel, it is not very suitable for the automotive industry in terms of size, but it seems to me that it is already suitable for the aviation industry. True, the latest news about the tests of Boeing-a hydrogen-powered aircraft refer to 2008. Probably need to write off silence on the crisis.
But there was a Russian aircraft TU-155 , the development of which began in 1988. It can run on hydrogen fuel, as well as on liquefied gas. If there are more fuel options please write in the comments.
