A big sunbird in the sky!!

Zephyr

What is surprising you with this picture? The aircraft flying in the night is a solar powered!!
The Zephyr,unmanned flew non-stop for 82 hours, 37 minutes and it was a demonstration for US military.

A UK-built solar-powered plane, with its 18-metre wingspan incorporates world-leading technologies.


It can cope up with temperatures from 45C to -75C and it flies on solar power generated by amorphous silicon solar arrays no thicker than sheets of paper, which are glued over the aircraft's wings.

To get through the night, the propellers are powered from lithium-sulphur batteries which are topped up during the day and is capable of carrying a 450-kilos.

Awaiting its arrival for the public so that it can be used as an alternative when the oil prices hike!!
