The Solar Impulse HB-SIA which uses no fuel, which had its first successful 24-hour flight in early July, will make three test flights across Switzerland – from Payerne to Geneva, from Geneva to Zurich and then back to Payerne.
The Solar Impulse project was set up seven years ago, in Payerne, Switzerland. The plane’s batteries have been replenished by 12,000 solar cells located on its wings. Its 208 foot wingspan is powered by electric motors which gather energy from the batteries.
The date for the domestic flights has not been confirmed. A purely solar powered flight around the world may take place by 2013 or 2014.
