Solar planes

I am going to talk about solar-powered planes and about what consequences will have in the future. This type of planes has been recently discovered. These ecologic planes use solar energy to move through the air and in their wings there are solar planes which obtain  the energy from the sun. 

The advantages of solar-powered planes are: The air isn't polluted because they use green energy, the solar energy doesn't disappear as the kerosene. The disadvantages are: that this type of technology isn't developed enough, because these planes can't be flying for more than half an hour and can't transport a lot of weight, either.

All in all, I think that these planes in the future will be very 
useful, because one day the fosil fuels will disappear. I hope that governments investigate more in this type of technology, because it will be our future.

solar-powered, to land >< to take off, to glide (hang-gliding), smooth (suave) >< rough
