Actually there are many Remote Controlled Plane Models that use solar power for flight.
And there are actually real life sized planes that use solar power as well.
This question has been answered by a team from The National University of Singapore NUS.
You may have heard about the quadcopter that used ground based solar charging station for its battery pack. But this time is different.
This quadcopter uses solar power for real time flight.
This means that it can hover as long as it is exposed to direct sun shine.
It also means that it can fly for hours more than any industry standard quadcopter.
It has no onboard battery packs and it's completely powered by an array of 148 solar cells.
The quadcopter frame is built from carbon fiber and its total weight is 2.6kg.
Its
You may ask about what such a quadcopter can do. This is obvious as it's still in development phase and it has been made mainly as a proof of concept.
But anyway this is a huge success for quadcopter industry.
This quadcopter makes Asia the first to develop a totally solar powered quadcopter that doesn't need any battery packs.
