Lisa Hy-Bird Seaplane Aims to Circle Planet on Solar Power

A firm from France aims to fly a plane around the world powered by '100-per-cent clean' energy, two years before a rival Swiss team.

A small French company is rivaling a bid by Vaud adventurer Bertrand Piccard and his Solar Impulse team to fly an environmental plane around the world. Piccard and his associate André Borschberg revealed their project earlier this year to circumnavigate the globe for the first time in a solar-powered aircraft. But in a front-page article today, 24 Heures reports today that a small French company, Lisa Airplanes, plans to circle the planet with its own environmentally powered Hy-Bird plane in 2009 - two years ahead of the Solar Impulse.

“Our idea is to create a spirit of competition around clean energy,” said Eric Herzberger, one of the co-founders of Lisa Airplanes. Conceived in Chambéry, Savoie, the Hy-Bird uses a fuel cell to power a 44-kilowatt engine, driving a propeller mounted on the tailfin. The 1.1-tonne plane has a 20-meter wingspan, compared to one of 80 meters for the four-engine Solar Impulse, which weighs 1.5 tonnes.

Lisa plans the Hy-Bird as a prototype of a plane it hopes to bring into production at a retail price of SFr620,000. The plane, being developed with a modest SFR6.5-million budget, would be 90 percent powered by a fuel cell and 10 percent by solar energy. Borschberg argues the Hy-Bird is not directly competing with the Solar Impulse because the Swiss plane is 100 percent powered by solar energy, using photovoltaic cells.


The plane was modified to include a hybrid battery and fuel cell system developed by UK firm Intelligent Energy.

Recent events in the aviation world suggest that solar-powered aircraft are poised to literally -- and figuratively -- take off, including a record breaking flight over Yuma, Arizona by the Zephyr. Pictured is Solar Impulse concept.

Two-passenger flying-car can fly short distances and travel up to 40 miles as an EV.
