The winning MIT went about the task in a brilliant way: They offered shares of the prize money to anyone who reported the weather balloons' locations. And what do you know? Tips about the locations came flooding in as people saw green: Arizona, California, Delaware, Florida, Georgia, Oregon, Tennessee, Texas and Virginia.

This challenge and the way it was won goes to remind us that a combination of the old and the new, viral campaigns and simple cold hard cash, can be unbeatable. Now let's just not run off to use that oh-so-new knowledge for anything potentially evil, please. [Guardian]

The big trick with these homemade blimps is using hot air (read:fire) for lift power, like a hot air balloon, instead of helium or hydrogen. Dan Nachbar's Skyacht is one of the more intensely engineered crafts, with steerable thrust and an intricate system of ribs that lets the engine sit in the tail itself. Brian Boland's Lips, on the other hand, has a simpler design, and fits in the back of a car.

If I built a blimp, I would make it look like a shark, and I would sneak up on other people's blimps, so it would look like my blimp was about to eat theirs. [Popular Mechanics]

The mission was dubbed BEAR-4 (Balloon Experiments with Amateur Radio), and used an 1800g balloon for a total weight of about 3.84lbs.

The camera was kept in place by foam blocks, and hooked up to five AAA Lithium L91 battery cells. With the extra legs, it captured almost four and half hours of footage. Mercifully, they've edited that down for the results you see below. [BEAR]

Bonus: remember those kids who photographed space for $150? They've now put together a time lapse video of all the photos their rig took during its flight. Not quite as cool (or expensive) as the video above, though. [L337arts]

Nah, it's one of the many art installations sprinkled over the dusty playa at Burning Man 2009. This year's theme is Evolution: A Tangled Bank. Safe travels if you're a weekend burner headed to the Blackrock Desert, and don't forget the distilled white vinegar to neutralize that alkaline playa dust!

One year later (and having travelled around three continents since), that stuff is still turning up in random places like my hiking shoes. [San Francisco Chronicle]

Instead, Ford uses full-sized balloon vehicles—inflatable pretend cars that can be crashed into with no resulting damage (to either the crasher or the crashee). They've been custom made for the company, which is no big surprise since they aren't exactly off the shelf toys (yet).

Each of Ford's dozen or so balloons cost $10,000 and manage to weigh but 40 pounds. When splattered with a bit of metal paint, Ford's collision detection system sees the balloon as any other car to be avoided on the road—and if for some reason the system fails to see anything, well, you have another fun game of car soccer. Hopefully Ford hasn't been scoring too many goals, if you know what I'm saying. [detnews via NewLaunches]

As Mark said, there's something strangely anthropomorphic about a giant, slightly-cartoony helium aircraft balloon going up, seen here at Flughafen Zürich. I love this almost as much as I love the word flughafen. Bring it to the US! [Aleksandra Mir via Like Cool]

Couch brought GPS but he also brought along a satellite phone, altimeter, and a second GPS device attached to his chair for redundancy. Then there was his pole with a hook, for bringing wind-whipped helium balloons into firing range, and containers of Kool-Aid, which served as ballast. His in-flight meal consisted of boiled eggs, jerky and chocolate. Video:

For his efforts and meticulous preparation, Couch, a 54-year-old gas station owner, was able to keep the balloon rig at 200 feet for most of the 200-mile journey.

"If I had the time and money and people, I'd do this every weekend," Couch said before getting into the chair. It was his third balloon flight in three years. "Things just look different from up there. You've moving so slowly. The best thing is the peace, the serenity." And landing, Couch, landing. Right? [CNN]

His body was found yesterday by the Anna Gabriela, a tug working for Brazilian oil company Petrobras, 683 miles (1,100 kilometers) from Father De Carli's starting point. His trip started on April 20 after a mass, and his last contact was a desperate attempt to learn how to use his GPS and communicate his position as the wind took him deep into the Atlantic Ocean.

I need to contact someone who can teach me how to operate this GPS, so I can give the latitude and longitude coordinates, which is the only way that people on the ground can know where I am.

An Petrobras official spokesman said that "his clothes and shoes indicate that it's him." And now I don't know if I should say "Godspeed, Padre" or "this is another candidate for the Darwin Awards," so I would just say rest in peace.

The first flight took him from the Brazilian town of Ampére to San Antonio, in Argentina, complete with tin foil pants and a DIY seat. He landed without any incident, getting rid of the balloons to lose altitude until he reached the ground.

The second flight isn't finished yet. Or at least, not officially. This time he had with him a GPS unit, which he planned to use to relay his coordinates to the ground.

There was only one problem: he didn't know how to use it correctly. Padre Adelir de Carli took off after a special mass last Sunday, at 1PM. The weather was bad, but he didn't care. He wanted to fly again, this time to beat the record of flight distance with party balloons. And besides, he was sure his new GPS was going to provide him with some safety, a way to ask for help with his precise location in the case anything went wrong.

The plan didn't work out. The strong winds took him 31 miles into the sea, and a little bit later, frustrated, he requested help from people on the ground:

I need to contact someone who can teach me how to operate this GPS, so I can give the latitude and longitude coordinates, which is the only way that people on the ground can know where I am.

Sadly, nobody was able to explain to him how to do it correctly and, around 9PM—the time of his last contact—he disappeared. After a two-day search using military police helicopters, and the cooperation of local fishing boats, it seems Father de Carli's flying dreams are not going to have a happy ending. The last thing that people found were fragments of balloons, next to the beaches of Santa Catarina.

I'm sure some people will call him an idiot for not learning how to use the GPS first, but what is more interesting in this story is asking how technology could still be so difficult to use. Is it really necessary to read an instruction manual or get directions to operate a gadget? The answer is simple: It doesn't have to be.

I'm supposed to be a "technology expert," dealing all day long with gadgets, but I still find plenty of devices that are a complete user interface nightmare. Things that require instruction manuals when there are no excuses anymore to design clear, straightforward interfaces that can be accessed by people with zero experience in technology.

I see this sad event, which has ended in the tragedy of a missing person—obviously he's a bit crazy and this is all his fault—as an example of all that is wrong with the design of machines today. Not because technology itself was the cause of him getting lost—it wasn't. It was more bad luck and bad planning than anything else. After all, his first flight was a success without GPS, and men have been wandering through Earth without any help for thousands of years.

The problem here is that I can imagine his frustration, trying to make sense of an infernal device so he could tell people his exact location, all the while knowing that he was going to get lost forever in the immensity of the sea.

And while we don't put ourselves in these crazy life or death situations every day, it wouldn't be bad if manufacturers actually invested some money and intelligence in making technology truly accessible. Not just a bunch of circuits and software tied together with extremely badly-designed UIs that merely alienate the user, but devices that can actually help people and make their experiences enjoyable.

Until then, I'm afraid we will have to live with thousands of useless gadgets that not men, and neither God will ever truly understand. [G1 and G1]

The one major problem is that the balloons only survive for about 24 hours before they are destroyed in the upper atmosphere. However, if that shortcoming can be overcome, Google could build wireless networks using a 700 Mhz spectrum in a fraction of the time and at a fraction of the cost of traditional cell towers. And as a BusinessWeek article from last month revealed, Space Data believes it can cover the whole country with a WiMax broadband network with just 370 balloons. Compare that with the 22,000 or so towers that would be necessary using traditional methods. It may be non-traditional but it is a dammed good idea. My mind has just been blown.
