Amazon is exploring the use of giant airships to serve as mobile, flying warehouses that could help the online retail giant deliver more of its goods by drone.

You might already be familiar with Amazon's drone delivery service, which recently received a demo in the United Kingdom for the first time. But the idea for a fleet of large airships, disclosed in filings to the US Patent and Trademark Office, expand on those ambitions dramatically. (Amazon chief executive Jeffrey P. Bezos also owns The Washington Post.)

Imagine you're at a baseball game and wanted to buy a meal or a jersey without ever leaving your seat. The system Amazon describes would allow you to place an order and receive the item within minutes. From its so-called "airborne fulfillment centers" hovering near the stadium, Amazon would dispatch a drone with your purchase. The drone would float or glide most of the way, then turn on its propellers and navigate itself to you directly.

While Amazon's existing goal with drone delivery is to get you your stuff within 30 minutes, airships could potentially reduce that time even further. Unlike Amazon's land-based warehouses, which by definition can't move around, airborne fulfillment centers could respond to surges in demand even before they occur, according to the patent filing.

Large gatherings of people for a specific event, such as a concert or a sports game, are one example Amazon highlights as a clear-use case. But Amazon also appears to believe that using airships could reduce the costs of drone delivery in general.
In looking to airships, Amazon draws upon a long technological tradition dating back to the 19th century, when some of the world's first self-propelled dirigibles were created.Jav Movie

Sending drones out from a ground-based facility requires substantial energy, the filing says, because the drone must have its propellers spinning constantly to stay aloft. What's more, having to make a return trip to the warehouse with no payload onboard could be a wasteful expense. By contrast, Amazon believes it could be more efficient to deploy drones from airships; the drones could float or glide most of the way down to earth by way of gravity, rather than using their own power.
The airships would have to be resupplied periodically, of course. Amazon envisions still more airships - smaller ones - that could shuttle more drones, products and other things needed to keep the airships functioning up to the larger carrier.

There's no word on when such a system might debut; an Amazon spokesperson didn't immediately respond to a request for comment. Some patents never even lead to actual products. But companies such as Facebook and Google have floated the use of airships and drones to beam Internet connectivity down to earth, so it was likely only a matter of time before Amazon began thinking about how to apply the same technology to its business.Jav Teacher

Post demonetisation deadline to deposit banned Rs. 500 and Rs. 1,000 notes ends on December 30.
NEW DELHI: Fifty days after the government banned most of the cash in circulation without warning, the deadline to deposit outlawed 500 and 1,000-rupee notes ends today. From tomorrow, it will be illegal to have old notes barring exceptions. The cash crunch and queues at ATMs may continue because of the huge demand for new bills. Prime Minister Narendra Modi is expected to address the nation tomorrow on New Year's Eve on the notes ban, which was announced last month as a big move to check black or undeclared money.Jav FreeFrom tomorrow, there will be steep fines for having more than 10 banned notes. People will be fined 10,000 rupees or five times the value of the notes, whichever is higher.
Those who couldn't deposit old notes because they were abroad, in inaccessible areas or are in the military can do so at the RBI till March 31.
Anyone caught giving a false explanation for not depositing their old notes earlier will be punished with a fine of Rs. 50,000 or five times the value of the notes.
Up to 25 banned notes will be allowed for study, research and numismatics.
After the notes ban, the government had fixed a limit of 24,000 rupees per week on withdrawals from bank accounts and 2,500 rupees per day from ATMs to ration cash. Many banks have urged the government to continue the restrictions as there is still not enough cash and the demand vastly exceeds supply.
Banks started accepting deposits in scrapped notes from November 10, two days after PM Modi announced the sudden ban on the two highest value currency notes.
There were endless queues at ATMs, which had to be recalibrated for people to get the new 2,000-rupee notes.
Finance Minister Arun Jaitley said that clear results of the Prime Minister's November 8 announcement are already in, with tax and revenue collections up.
Attacked by the opposition Congress, the Trinamool and Left over the impact of the notes ban on people, the ruling BJP will launch a massive political campaign in the new year to back demonetisation and the Modi government's drive to transition to a cashless economy.
According to the Reserve Bank, more than 13 lakh crores in old notes have returned to the system as deposits.Jav Streaming HD Online Free
