As anticipated, the Solar Impulse HB-SIA experimental solar-powered aircraft completed the first ever solar-powered intercontinental roundtrip journey between Europe and Africa today. The roughly 6,000 km (3,728 mile) trip commenced on May 24 and consisted of a total of eight legs averaging 800 km (497 miles) before reaching its conclusion with a landing back where it all began in Payerne, Switzerland at 8:30 pm on July 24, local time.

The final leg of the journey was piloted by Bertrand Piccard, who shared duties in the single-seater cockpit with André Borschberg over the course of the journey. Originally built to prove that an aircraft powered only by the sun’s rays could be flown at night, which it proved in 2010, the HB-SIA prototype aircraft has continued to rack up a number of solar aircraft distance records.

Over the course of its latest record-breaking journey, the aircraft visited Madrid, Rabat, Ouarzazate, and Toulouse. Although its 400 kg (882 lb) of lithium batteries give it the ability to fly through the night, it often landed after midnight to avoid thermals. However, the Solar Impulse team says the aircraft was almost always brought back to the hangar with the batteries almost fully charged.

“It’s been an extraordinary adventure not only for what we’ve achieved with this airplane, originally only designed to demonstrate the possibility of flying day and night with a purely solar energy, but also for what has resulted in a tightly fused team, confident in the project and in their capacity to make it happen.” said André Borschberg, CEO of Solar Impulse.

On its final leg from Toulouse to Payerne, Solar Impulse traveled 615 km (382 miles) in 13 hours 29 minutes at an average speed of 63 km/h (39 mph) and at an average altitude of 3,596 meters (11,800 ft).

The next challenge for the Solar Impulse team is a round the world flight that it hopes to complete in 20 to 25 days. This flight is currently planned for 2013 or 2014.

While technically true intercontinental does tend to imply range in the multi-thousand kilometer range. If I fly a Piper Cub across the Strait of Gibraltar Do I really have an intercontinental airplane?


SB that was weak. But I guess it's hard to find a way to put down this great "green" accomplishment. 3728 miles without fuel, and you haters said it couldn't be done. The future is bright if you can take the politics out of it.

meh, these kind of things don't impress me. While I think future aircraft will be electric, it remains to be seen it the batteries will be charged on the ground, or if it will have a fuel cell on board, either way it wont use any war inducing oil.

That's right, I'm an anti-oil conservative republican, WE DO EXIST! lol

Actually, Cleantech in all its glory IS a Republican thing if you can get rid of the pesky fossil fuel profiteers. This is because with a cleantech community which is properly sustainable, we save so much money not having to shell out for geopolitics, depletion, climate, pollution, health problems, subsidies and inflation that at last you can finally get a serious tax rate reduction, increase your geopolitical stability, your energy security soars, you have more healthy people working so your GDP can grow and is no longer retarded by the inflationary impact of higher oil prices etc etc. The benefits go on and on but all we hear is "Drill baby drill" The only time this is OK is for geothermal.
