LOON FOR ALLBALLON POWERED INTERNET

WHAT IS PROJECT LOON??

It’s a project by GOOGLE

Project that aims to provide Internet all over the world via a ring of balloons floating in the sky, about 20 kilometres above the ground.

Project Loon balloons travel approximately 20km above the Earth’s surface in the stratosphere.

Project Loon balloons float in the stratosphere, twice as high as airplanes and the weather

Loon balloons go where they’re needed by rising or descending into a layer of wind blowing in the desired direction of travel.

How loon flies

?

• Loon uses software algorithms to determine where its balloons need to go, then moves each one into a layer of wind blowing in the right direction. By moving with the wind, the balloons can be arranged to form one large communications network.

Stratosphere presents unique engineering challenges: air pressure is 1% that at sea level, and this thin atmosphere offers less protection from UV radiation and dramatic temperature swings, which can reach as low as -80°C.

By carefully designing the balloon envelope to withstand these conditions, Project Loon is able to take advantage of the stratosphere’s steady winds and remain well above weather events, wildlife and airplanes.

LOON’S DESIGN

ENVELOPE

Inflatable part of the balloon is called a balloon envelopeBalloon envelopes are made from sheets of polyethylene plastic.They measure fifteen meters wide by twelve meters tall when fully inflated.When a balloon is ready to be taken out of service, gas is released from the envelope to bring the balloon down to Earth in a controlled descent.In the unlikely event that a balloon drops too quickly, a parachute attached to the top of the envelope is deployed.

SOLAR PANELS

•Balloon’s electronics are powered by an array of solar panels.

•Solar array is mounted at a steep angle to effectively capture sunlight even during short winter days

Divided into two sections facing in opposite directions , it allow us to capture energy in any orientation as the balloons spin slowly in the

wind.The panels produce approximately

100 Watts of power in full sun, which is enough to keep Loon’s electronics running while also

charging a battery for use at night.

By moving with the wind and charging in the sun, Project Loon is able to power itself using entirely

renewable energy sources.

Radio antennas to communicate with other balloons and with Internet antennas on the ground

Lithium ion batteries to store solar power so the balloons can operate throughout the night.

HOW LOON CONNECTS?

Each balloon can provide connectivity to a ground area about 40 km in diameter at speeds comparable to 3G. For balloon-to-balloon and balloon-to-ground communications, the balloons use antennas equipped with specialized radio frequency technology.

After the loon is completely designed it looks like this.

Entire earth can communicate using internet provided by LOON
