Switzerland. 20 Francs 2015. Solar Impulse

To fly around the world using just the energy of the sun is a dream which, up until
recently, still seemed impossible. Solar Impulse wants to take on this challenge. The
solar airplane passed the main test, the historic crossing of the USA from west to
east in two months, in the summer of 2013. It thereby clearly illustrated how clean
technologies can reduce the consumption of natural resources and our dependence
on fossil fuels. The successful pioneer flights of the Solar Impulse 1 prototype have
broken numerous records and attracted attention throughout the world for the solar
project of Bertrand Piccard and André Borschberg. The construction of the second,
improved plane was started in 2011. The aim is to tackle the round-the-world trip
before the end of the year. The Federal Mint Swissmint is honouring this bold project
with a 20-franc silver coin. This was designed by Angelo Boog from Wallisellen.
