Project Loon in which Google is going to release balloons near the space boundaries in the stratosphere
By venture with Telecommunications companies the balloon network provides Internet coverage to rural & remote areas. The signal is then passed across the balloon network and back down to the global Internet on Earth.
Many of us think that the Internet is a global community. But 2/3 of the world’s population yet does not have Internet access. Project Loon is a network of balloons traveling in stratosphere. It will help people bring back online after disasters.
How It will Work?
Project Loon balloons float in the stratosphere, twice as high as airplanes and above the weather. In the stratosphere, there are many layers of wind, and each layer of wind varies in direction and speed. Loon balloons go where they are needed by rising or descending into a layer of wind blowing in the desired direction of travel.

Design of Loon Balloons
Loon balloons have major 3 parts
1. Envelope
2. Solar Panel
3. Electronics
Envelope
The inflatable part of the balloon is called a balloon envelope. A balloon envelope is made of a special material will last around 100 days in the stratosphere. The balloon envelopes are made from sheets of polyethylene plastic, and they measure 15 meters in diameter & by 12 meters hight.Solar Panel
Electronics of the balloon is powered by an array of solar panels. The solar panel array is made of flexible plastic laminate mounted on light-weight aluminum frame. It uses high efficiency mono-crystalline solar cells. The solar array is mounted at a steep angle so it can effectively capture sunlight at the most at higher latitudes. The array is divided into two sections facing in opposite directions, allowing us to capture energy in any orientation as the balloons spin slowly in the wind. These panels will produce approximately 100 Watts of power in full sunlight, which is enough to keep working Loon’s electronics.

Electronics
A small box containing the balloon’s electronics hangs underneath the inflated envelope, like the basket carried by a hot air balloon. This box contains circuit boards that control the system, radio antennas to communicate with other balloons and with Internet antennas on the ground, and lithium ion batteries to store solar power so the balloons can operate throughout the night.
An overview of the project is given below
