An aeroplane that flies on solar energy, science fiction? It exists
already, reports De Telegraaf that has a story on the so-called
Solar Impulse, which will be presented in Switzerland on Friday.
The plane has 11,000 thousand solar panels and it can climb to
12,000 metres.
Downside is it can only take one passenger and aviation experts are
sceptical to say the least, reports the paper. They say that it
will never be possible for a large passenger plane to have enough
solar panels to generate enough energy to fly. Biofuel is seen by
the experts as a much more realistic green option for flying.
