Project Loon - Google


          Project Loon balloons float in the stratosphere, twice as high as airplanes and 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’re needed by rising or descending into a layer of wind blowing in the desired direction of travel. 

People can connect to the balloon network using a special Internet antenna attached to their building. The signal bounces from this antenna up to the balloon network, and then down to the global Internet on Earth.

Project Loon balloons travel approximately 20 km above the Earth’s surface in the stratosphere. Winds in the stratosphere are stratified, and each layer of wind varies in speed and direction. Project 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.

Situated on the edge of space, between 10 km and 60 km in altitude, the 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.

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. Project Loon currently uses ISM bands (specifically 2.4 and 5.8 GHz bands) that are available for anyone to use.

Project Loon began in June 2013 with an experimental pilot in New Zealand, where a small group of Project Loon pioneers tested Loon technology. The results of the pilot test have been used to improve the technology, and continued refinements are now being tested in an ongoing series of research flights in California’s Central Valley.

Xbox One v/s PlayStation 4

Costing at last £400 each with a game, this is one decision you'll want to get right though. To make it easier, we've compared the Xbox One and PS4, from the games you can get for each system to the tech that powers them.
Let's get started.

Top reasons to pick XBox One Top reasons to pick PS4
Larger size may mean it’s more reliable long-term
The huge console size of the Xbox One gives air more room to circulate, which is likely to ensure the console does not overheat even when under strain for prolonged periods.

It has a better launch line-up
At launch, the Xbox One offers a better selection of games than the PS4. Dead Rising 3, Forza Motorsport 5 and Zoo Tycoon are games we’d rather play over Killzone: Shadowfall. Several of the games we thought would be PS4 launch exclusives have been delayed until 2014. 

Kinect is undeniably cool
Not everyone likes Kinect, but it has serious potential that you don’t get with the PS4 camera. For example, you can use it to control the console, swiping in the air to perform commands. 

Wider distribution of Kinect will mean for more interesting motion gaming
Even more important than the inbuilt features of Kinect, that every Xbox One ships with a Kinect sensor means that developers will be able to confidently put Kinect features into their games. As not everyone will have a PS4 camera, the gaming audience is fragmented. 

It acts as a hub for your other home entertainment gear
You can plug another piece of hardware into your Xbox One using its HDMI input. This lets you switch between, say, your digibox and the Xbox One, using the Xbox interface. There’s only one input, but if you use a receiver it’s all you’ll need. 

Titanfall is an Xbox One console exclusive
One of the most anticipated next-gen games is Titanfall, a game made by some of the sharpest minds behind the Call of Duty franchise. It’s apparently going to be a PC/Xbox exclusive ‘forever’, so if you want it, you want an Xbox One. 
It’s much smaller than an Xbox One
If you have a cramped lounge/bedroom, the smaller size of the PS4 will come in handy. It is much, much smaller than the Xbox One. 

It doesn’t have a separate power brick
Also important, the PS4 incorporates its own power supply while the Xbox One has a separate power brick. This is a big win if you want to take the console around a friend’s house as it’s much, much lighter. 

It already has iPlayer
The PS4 has iPlayer already, the Xbox One does not. If you want to use your console as a TV streamer, this is important. iPlayer is coming to Xbox One, we’re just not sure when. 

It’s a bit cheaper
As it does not the Camera accessory bundled, the PS4 is significantly cheaper than the Xbox One. It costs £349.99 on its own. The Xbox One is £429.99.

The PS4 is more powerful
The PS4 has a significantly more powerful GPU – graphics processing unit – than the Xbox One. It’s about 50 per cent more powerful. 

Remote Play for Vita is awesome

This one only matter for PS Vita owners, but the PS4’s Remote Play is pretty neat. It lets you play full PS4 games on your Vita over your Wi-Fi connection. 

PS Plus’s free games plan is great
The PS Plus service costs about £40 a year, but it gets you free games every month. And at present it’s better than the freebie games offering you get with an Xbox One through Live Gold. 

The PS4 controller is better

We think the PS4 controller is better than the Xbox One’s. This one will divide opinions, but we’re not fans of the clicky triggers on the Xbox One pad.

Futuristic Delivery Service by Amazon

CEO of Amazon Jeff Bezos uncovered a new Plan by Amazon of Delivering with help of Drones. Amazon's R&D team is testing a Drone (octo-copter) for Delivering Customers Packages withing time span of 30 Minutes.
This new Plan was Announced on the CBS show 60 minutes where Jeff Bezos Stated that "The service will deliver packages within 30 minutes".

Bezos told 60 Minutes that the service could be up and running in as few as four years — although he noted that he is an optimist when it comes to such things.

"One day, Prime Air vehicles will be as normal as seeing mail trucks on the road today," the company said.

This is the latest futuristic effort by Bezos, who was an e-commerce pioneer in the 1990s and more recently popularized the e-reader — while pursuing personal projects such as private spaceflight and a 10,000-year clock built inside a mountain

Later a Video was posted by Amazon showing Flight Test of Prime Air in Action

To launch this Service Officially for commercial use it will still take couple of years to Improve and Advance the technology and Full Fill all the FAA (Federal Aviation Administration) rules and Regulations. If everything works as planned we can see the drones delivering packages by air in year 2015.
