Swiss taxpayers have been footing the bill – amounting to more than SFr1 million ($1.04 million) - to house the Solar Impulse project at its base at Dübendorf military airfield near Zurich since 2007. Now the government wants the project to pay up.
Swiss public radio revealed on Tuesday that the Federal Audit Office had established there was no “legal basis” for Solar Impulse not to have paid rent for the use of the hangars at Dübendorf or Payerne in canton Vaud.
SFr700,000 worth of modifications made to the Dübendorf hangar in order for it to house the giant solar plane were also picked up by the government.
Sponsored by Deutsche Bank and Omega, the Solar Impulse project aims to fly the first fully solar-powered plane around the world in 2014 to promote the use of clean energy.
A spokeswoman for the defence ministry, which operates the Dübendorf airfield, said although it had requested rent from Solar Impulse in February last year, “Solar Impulse has not yet signed the lease”.
The ministry has also asked Solar Impulse to pay rent to cover costs from 2014.
A spokeswoman for Solar Impulse said the matter was being discussed with all government departments concerned.
