Every day, commercial airlines from around the world spend half a million tonnes of carbon dioxide into the air. However, there is now a glimmer of hope. A group of Swiss researchers develop aviation technology while keeping the skies remain clear.
Solar Impulse, the solar-powered airplane that made the research team was able to fly from the runway and landed no more than one day.
Solar-powered unmanned aircraft had been present since around the 1980s. However, the Solar Impulse live flight done while carrying a pilot, namely Andre Borschberg, one project leader of the research.
The flight was, as quoted from Discovermagazine, December 20, 2010, made possible after the researchers put 12 thousand photovoltaic cells in the tail and the wings that reach 64 meters in length.
Photovoltaic cells that send the extra energy to the battery during the day and was able to supply power to the four propellers are there to keep working at night.
In total, Borschberg succeeded in its sun-powered plane that flew for 26 hours non-stop without any use of fuel oil.
However, current technology solar-powered aircraft have not been able to replace commercial jet aircraft. For information, Solar Impulse is only able to fly with an average speed of 24 miles per hour or about 38 kilometers per hour. Cruising speed is roughly equal to the maximum speed of human running.
