But, yes, these people benefit too. As this tech is deployed, so many souls in places like Africa and Southern Asia gain access to possibilities currently beyond them. Google recently inked a deal to test its balloons with Internet service providers in Indonesia. In a clean room just down the hall from where others are honing technologies for the company's self-driving cars, they build both the laser systems needed to send data and the detection systems needed to receive it.
The lasers transmit an invisible shaft of light that's about the diameter of a chopstick and must be accurate enough to hit a 1. Then, a series of additional mirrors and lenses focus it onto the data receiver, which is a mere 60 microns wide, or slightly smaller than a human hair. All this means the setup also requires second breed of laser: a beacon the balloons shine at each other as a way of reading each other's position.

The beacon sends a fairly broad signal, kinda like the signal that your remote control sends to your television. But this is merely a way of lining up the two balloons so they can aim the far more focused data signal straight at its target. Over such a vast distance, this is a delicate process. But Google has shown that, in good conditions at least, it can reliably send data in this way. Erkmen compares this to someone trying to aim a laser pointer at a tiny spot across the room. From just 15 feet, he says, that's enormously difficult, and it becomes even more so as that distance grows. Give it a try sometime.
The hope, Erkmen says, is that the company can build a flying network that can bring the Internet to areas where laying terrestrial cables is too difficult and too costly. In theory, Erkmen says, they could connect an unlimited number of balloons. This is still a massive task.
vocasupria.tk But for Ford, it's doable. Weather can degrade optical signals. So can scintillation, the atmospheric phenomenon that makes the stars twinkle. But at 20 miles above the Earth, Google's balloons will float above the scintillation problem—and a lot of the weather.
And when the balloons send wireless signals down to the phones below, weather and scintillation aren't as much of an issue, in part because Google may use electromagnetic technology such as WiFi and LTE, rather than optics. Google's lasers do have their limitations. They can't, say, fire a beam of light down to Earth and pop a giant vat of popcorn , Real Genius -style.
Conversely, air filled balloons will not last anywhere near as long. It is important to note that taking balloons outdoors should be avoided as much as possible. Balloons will react badly once vulnerable to heat outside as the heat will increase the rate at which helium escapes from the balloon. So make sure to keep this in mind for when inflating balloons for your event. The cost of balloons — When it comes to a price factor between balloons, it is important to note that when balloons are filled with helium it is much more expensive to sustain than air.
