Solar-Powered Airplane Completes First International Flight
liqs8143 writes "Solar Impulse, a fully solar-powered airplane, has completed its first international solar-powered flight. After a flight lasting 12 hours 59 minutes at an altitude of 12,400 feet, using no fuel and propelled by solar energy alone, Solar Impulse HB-SIA landed safely in Brussels, Switzerland. After the landing, company co-founder Bertrand Piccard said, 'Our goal is to create a revolution in the minds of the people . . . to promote solar energies — not necessarily a revolution in aviation.' Compared with 2003, energy efficiency has increased from 16 to 22 percent. And the cells are now half as thick. The project has a total cost of $88 million, which is funded by mostly-Swiss partners and public donations."
Too lazy to RTFA, but couldn't you have indicated the embarkation point? Austria to Switzerland? Not too interesting an international flight. New Zealand to Switzerland? Now we're talking.

That would be _to_ Brussels, _from_ Switzerland, I'm guessing.
on that fancy solar plane? Otherwise someone would have noticed they were flying to Belgium, not Switzerland.
Solar Impulse HB-SIA landed safely in Brussels, Switzerland. ... never knew Brussels was part of Switzerland ...O wait ... guess I should go hand in my Belgian passport and go request a Swiss one ....
Damn
Awesome Geography ./ !
Not wanting fancy QC for ./ - but OP should preferably understand the material posted, yes?
Is it just me, or is youtube not meeting demand on Sunday afternoons and evenings? Or is it comcast?
Why the f even have editors here. Jeezus.
A glider can soar for whole day if it has no pilot and sufficient wings. And they managed to fly from one puny country to another. I can set up an international flight using a paper plane. I just go close to the border and throw it. (Although border patrol might then held me up for suspicion of illegal transport of goods)
I would be careful taking a red-eye on the Solar Powered airline!
I didn't fly across the Atlantic, a savings of 100%
Gently reply
The red tape they had to wade through to authorize it was much more painful... Actually crossing the EU probably isn't so bad... wait till they try to fly around the world.. Getting the proper clearances will take much longer than the trip itself... Just ask Dick Rutan
For justice, we must go to Don Corleone
I'm not impressed. Solar planes have been in existence for a while. http://www.nasa.gov/vision/earth/technologies/solarFarm.html I really won't be impressed until it can carry cargo or passengers.
Gaytube, now really?
Brussels is in Belgium. Obviously the Article was submitted by an American. I assume this was a Switzerland to Brussels flight. A few hundred kilometers. More if I see flight details.
So what happens when the plane is hit with a strong headwind? Mongolia?
Actual flight path in title. Approx 660km @ 50km / hr, with cleared airspace due to special needs. See http://www.solarimpulse.com/blog/2011/05/13/all-lights-at-green/ Herzliche Glückwünsche to the team.
wa da ta my damie
No range, no speed, it will not replace neither B-747 nor F-15 any time soon not even if it can go all around the word. Maybe it was designed just for test or for other purposes. It could stay flying high over a city for long time while retransmitting radio signals or with radar watching for low flying planes or missiles. Comparing it to a solar powered car does not make sense to me because the most basic reason an airplane is different from a car is because it can easily flight over land, mountains and water and that is impossible for a car solar powered or otherwise.
I am deeply sorry, but I have to agree with TheNAM666 here. This does look like a typical American write-up. Just like that time a security lady at an airport in the US was questioning me about why my Dutch passport was made in Switzerland. It got made at the consulate in Stockholm. Or that time when the Israeli border check said the same damn thing.
I have found that both Americans and Israelis have displayed the most spectacular levels of ignorance about the world outside of their own country. More so than other travelers and people I've met in my life. That's not to say all Americans and Israelis are stupid, far from it. It's just that the ratio of numbnuts to decent conversationalists is significantly higher.
Coolest example ever was when Dutch customs at Schiphol airport were looking for something because they were asking every passenger that passed through a certain spot where they just arrived from. They put the question in Dutch first. An American lady in front of me looked at the customs officer and in reply to his "Pardon Mevrouw, waar komt uw vlucht vandaan?" she barked an irritated "I don't speak German".
He smiled, inclined his head and replied "That's alright, madam. Neither do I."
What? Less than three hundred miles!
Must have been a slow news day.
So when i say I'm going from Washington to Denver by road and it takes less than 4 hours.
Or
I'm going from London to Paris by road and it takes less than an hour.
What countries am I in?
I'd rather be riding my '63 Triumph T120.
Aircraft require more high density energy than any other thing humans do (besides spacecraft). Getting off the ground with any significant amount of cargo and traveling at a useful speed of several hundred knots requires many gigajoules of energy. Only fossil fuels have that kind of energy density and power output : even nuclear is too darn heavy compared to jet fuel.
In the long run, eventually we'll run out of recoverable fossil fuel. There'll still be plenty of it in the ground, but the energy cost to remove one barrel of oil will be too high for it to be economically feasible. (if it took 1/2 or 1/3 a barrel of oil in energy to recover one barrel of output, it would probably not even be worth it).
At that point, we'll have to convert all our cars and trucks to electrically driven vehicles : not from batteries, but from wires above or in the road (or both). Robotic vehicles that grab onto an overhead wire and a rail in the pavement at the same time on the straight aways, switching to ultra-capacitors when they change lanes or make turns is what I am thinking of.
We'll power everything with nuclear or vast arrays of solar and wind. And for airplanes, we'll have to make jet fuel synthetically from coal or even from CO2 extracted right from the air.
Everything I just named already exists. Some of the engineering details have not been worked out, but it's just a matter of money. So don't panic, the Western world will be fine.
...it took of in Helsinki, Sweden.
The Solar Challenger did a 262km international flight from England to France in 1981. Given that the Solar Impulse has a max speed of 50km/h (from TFA) and was in the air almost 13 hours, that suggests a flight in the neighborhood of 600km. Not bad but then, one would expect some progress after 30 years.

The video is a fake. No way is Switzerland that flat.
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
Switzerland is not a member of the EU so it does not make sense to move the de-facto capitol of said union there. Why not just keep it to Brussels, Belgium instead?

Last time I checked Brussels was in Belgium.
I hadn't the slightest objection to his spending his time planning massacres for the bourgeoisie... (P.G. Wodehouse)
In 13 hours they only went 660 km? Thats not likely to be a practical alternative to jet powered planes. And its not like they can keep going much longer than that, solar power is not so good at night.
My main issue with Solar Impulse is that it is not a solar powered aircraft but a sailplane with a solar powered assist. It uses stored electricity to get to altitude then uses standard sailplane techniques to get where it is going. You may call thermals and ridge lift (lift crated by wind being pushed up hill) solar power but it has nothing to do with solar panels. They probably use electricity to move from one area of lift to another but it is not the main source of energy. Considering that the sailplane distance record is almost 1000km, flying 500km with some electrical assist is not a great feat.
Why is the stated average speed of Solar Impulse 70km/hr but it took 12+hours to go 500km (average forward speed 42km/h). The reason is that they spend half their time using local lift instead of going forward.
I would like to see how far Solar Impulse would fly if it took off, set a course and flew straight until it ran out of electricity. That would be a valid comparison with today's fossil fuelled aircraft.
The only way to stop the Flemish and French speakers fighting over Brussels is to make it part of neutral Switzerland! Inspired.
This is gonna make huge savings on flights from new york (Jamaica)
I've always knew there was something cheesy about Brussel-Halle-Vilvoorde!
I'm going to get my Swiss-Belgian passport right now!
--- I am known for the ones who want to find me on the net. Is that a privacy risk or a privilege? One might wonder..
The summary isn't good (Brussels Switzerland?), but the articles suck.
Hrm, Slashdot isn't raising its standards to meet the rest of the world, the rest of the world is lowering theirs to meet slashdot...
Well, to be fair only that little portion is in English on the site. The rest of the page is written in some kind of Incomprehensible Dead Language. Crazy Gibberish!
I thought the Swiss were always neutral, when did they invade Belgium?
While everyone is focused on the middle east, the Swiss are taking over Europe!

When did Switzerland conquered Belgium?

Other than a 'hey, that's cool' factor, I don't get what the big deal here is. There's not a lot of information in the article or the video, but the suggestion is that this is some kind of breakthrough in powered flight.
A little bit of background: Even a small, single-engine airplane will burn 6-8 gallons of aviation gas per hour, and AVGAS is about $6/gallon (in the US - probably even more in Europe), and this is one of several reasons why aviation is increasingly inaccessible -- in the US alone, we had about 800,000 pilots in 1980, but today we have under 600,000. You won't rent even a two-seater for much less than $90/hr, which turns into $120-130 if you have a flight instructor there too.
So there is a lot of attention on alternative power sources for airplanes, but the big problem is weight. Most single engine airplanes already have weight issues -- a lot of your 4-seater aircraft like the Cessna 172 may have spots for 4 people, but (particularly with Americans these days...) you're unlikely to get 4 adults in there without going over max takeoff weight, even if you dump out half your fuel.
So in the practical category of 'planes with people in them,' this isn't really relevant -- the thing is a sailplane with a solar-powered assist and has probably had every ounce of material removed that can be removed. It's still pretty cool, since there are definitely uses for long-endurance UAV aircraft out there - but even small airplanes aren't going to be using solar (not enough juice) or batteries (too heavy) anytime soon. There are some concept electric designs out there, but the ones I've read about are either too slow or can't stay up for very long. The HB-SIA can only operate under very calm wind conditions (50 km/h won't go anywhere at altitude with a head wind) and with a lot of extra separation done by ATC as the article says.
Such endeavors though not ready to be practical yet, put focus on and prove the capabilities of solar energy
Microwave or lasers can power airplanes. Also research orbital solar power vs land based. Turns out that a solar cell in space gets about 6x more sunlight than on the ground.
