Boeing engineers use spuds to improve in-air Wi-FiThis 2006 photo provided by Boeing Co. shows early dielectric substitution testing using potatoes in a Boeing Test & Evaluation laboratory in Arizona. Boeing has developed an advanced method to test wireless signals in airplane cabins, making it possible for passengers to enjoy more reliable connectivity when using networked personal electronic devices in the air. Employing an odd mix of the low-tech and the high-tech, Boeing loaded a plane with sacks of potatoes as part of testing it did to eliminate weak spots in in-flight wireless signals.

CHICAGO (AP) — If the wireless Internet connection during your holiday flight seems more reliable than it used to, you could have the humble potato to thank.

While major airlines offer in-flight Wi-Fi on many flights, the signal strength can be spotty. Airlines and aircraft makers have been striving to improve this with the growing use of wireless devices and the number of people who don’t want to be disconnected, even 35,000 feet up.

Engineers at Chicago-based Boeing Co. used sacks of potatoes as stand-ins for passengers as they worked to eliminate weak spots in in-flight wireless signals. They needed full planes to get accurate results during signal testing, but they couldn’t ask people to sit motionless for days while data was gathered.

“That’s where potatoes come into the picture,” Boeing spokesman Adam Tischler said.

It turns out that potatoes — because of their water content and chemistry — absorb and reflect radio wave signals much the same way as the human body does, making them suitable substitutes for airline passengers.

“It’s a testament to the ingenuity of these engineers. They didn’t go in with potatoes as the plan,” Tischler said.

Recapping the serendipitous path that led to better onboard wireless, Tischler said a member of the research team stumbled across an article in the Journal of Food Science describing research in which 15 vegetables and fruits were evaluated for their dielectric properties, or the way they transmit electric force without conduction.

Its conclusions led the Boeing researchers to wonder if potatoes might serve just as well as humans during their own signal testing. Despite some skepticism, they ended up buying 20,000 pounds of them.

Video and photos of the work, which started in 2006, show a decommissioned airplane loaded with row upon row of potato sacks that look like large, lumpy passengers. The sacks sit eerily still in the seats as the engineers collect data on the strength of wireless signals in various spots.

The Boeing engineers added some complicated statistical analysis and the result was a proprietary system for fine tuning Internet signals so they would be strong and reliable wherever a laptop was used on a plane.

Boeing says the system also ensures Wi-Fi signals won’t interfere with the plane’s sensitive navigation and communications equipment.

“From a safety standpoint, you want to know what the peak signals are, what’s the strongest signal one of our communications and navigation systems might see from a laptop or 150 laptops or 350 laptops,” Boeing engineer Dennis Lewis explains in a video.

In a nod to the humor in using a tuber to solve a high-tech problem, researchers dubbed the project Synthetic Personnel Using Dialectic Substitution, or SPUDS.

The company says better Wi-Fi signals can be found already on three Boeing aircraft models flown by major airlines: 777, 747-8 and the 787 Dreamliner.

  • The protests take on a festive element as police forces move out of the park and square. Wearing a gas mask, this young man dances to traditional Turkish music in front of Taksim Square’s Ataturk Monument.

  • In Gezi Park since March 31st, this protester, originally caught off-guard by the Government’s teargas and water cannons, went out and bought a Russian army mask from WWII, preparing for what was to come.

  • This rambunctious boy seems to be enjoying the chaos. After taking this picture he threw a stone at the already destroyed building in the background.

  • Forming a line, the police face off directly with protesters in Taksim Square. After a while, they retreated and there was a general cheer – a back-and-forth dance that has been common since the beginning of this protest.

  • An elderly woman in Gezi Park reads the news. The tent community occupying the park was violently destroyed on June 16th.

  • Many different groups had set up booths to promote their cause in Taksim Square and Gezi Park. Standing in front of one, this man waves his flag while posing with conviction.

  • Many home-remedies are used to minimize the effects of tear gas. This woman has put a milky solution on her face, removing her mask after the tear gas dissipated. Before sunrise, the police came again for another round of teargasing.

  • People capitalize on the uprising -- selling flags, beer, gas masks, sky lanterns and spray paint to name just a few of the popular items.

  • On Monday morning, June 11, the police execute a strong offensive. Many plain-clothed police officers, like the ones seen here, clash with protesters in the side streets away from the main stand-off in Taksim.

  • The authorities seem to be most aggressive in the night, pushing protesters away from the square and park. After being teargassed this young woman catches her breath with other protesters on Siraselviler Street.
