Car-based electricity

Was made the first powered car running Alkahrabaaam 1832 and before the internal combustion cars, nearly seventy years. And the electric car is better than internal combustion vehicles in terms of low sound of the engine. This was followed by two cars in the evolution of the superiority of the internal combustion car for two reasons. : First, in preference to long-range, and secondly: the lack of weight the amount of fuel such as benzene or diesel for heavy weight battery to cut a reasonable distance. Was to develop the electric car to wait until that time now to catch the car that was powered by gasoline.

And some tests for electric car built after 2000 were Srathathblg of 210 kilometers per hour, and the other able to walk a distance of 400 miles. And Knhathtaltejrebh only and is not suitable for personal use Nzeralglu the normal price and the weight of their heavy battery. The recharge to the car takes 8 hours, and this a long time.

And has some international auto companies in the production of the electric car after 2005 and offered for sale in the markets, but the battery is still expensive price. You can well imagine that the car battery electric battery type lithium - ion battery equivalent to about 6000 of the kind we use in the mobile phone. And encourages the many governments in the United States of America, Japan, Germany and France, industrial companies and universities on the development to fit electric car, and support Governments in auto companies billions of dollars to encourage them to intensify efforts to develop the car, and specialty Europe millions of euros for research at universities to develop technology batteries, the new

The first inventor car worldfootball

The invention of the first car in the world, Karl Benz invented the motor car may
And that in 1885
The registration of this invention is in the city of Mannheim in January 29, 1886
Despite that great credit is due to Karl Benz invented the modern car
But in that time there were many German engineers working on the production of cars and that in the German city of Stuttgart in 1886
The Jotilb Daimler and Maybach Oelhm logged invention of the first steam wheel and actually experience cemeteries
In 1885
The German inventor Siegfried Marcus collects motorized wheelbarrow to the present invention, but not beyond the experimental stages, but stages only

New aircraft able to fly for five consecutive years,

Interest to the research agency of the U.S. Department of Defense, "DARPA" introduced a new aircraft able to fly for five consecutive years, without landing, and without air refueling. This is called the plane "Voltor" (Vulture), and can repair failures of communication networks, radio and video, in areas exposed to environmental disasters. Can also be harnessed to control the terrorist training camps are not visible. In other words, this plane will be used in the fields of military and civil.
The companies received (Aurora Flight System) and "Boeing" and "Lockheed Martin" funding agency "DARPA" to develop this type of aircraft capable of flying in the air for a period of five years, without interruption. Load up the plane, "Voltor" Cleogram to 500 and will fly at a height of 20 to 30 thousand miles. So far, attributed the record for flying a plane without a pilot a plane (Zephyr Aircraft) produced by the company (QinetiQ). It is succeeded in flying for 54 hours straight.
Consists plane "Voltor" of three aircraft will unite together in the air to form a jumbo jet has sold its wing (the distance between the maximum left wing and the maximum wing right) 160 m almost twice the wingspan of an Airbus (A380) which is the largest commercial aircraft manufactured for the day, about the world. Work will be "Voltor" free of toxic emissions. All electric motors are powered by photovoltaic panels focused on them.
The construction of aircraft "Voltor" on a large scale, in the future, will allow the implementation of the tasks that led some of the satellites, and Earth observation. Contrary to these satellites, these aircraft, when subjected to any crash, landing on the ground in order to be repaired before being returned back to its position in the air. .

Mortgage on the car

That institution or the bank may sell as have no power, go to the bank directly or institution, contracted to buy a car specifications given, and concluded with the contract or to give them a deposit or so. This may not be a sale; because of this institution or the bank did not yet have the car how sell something is not owned by, and the Prophet peace be upon him has said: Do not sell what you do not have.
Then with this banned is that the institution or the bank is selling what does not have a fact like to be a twist on usury, a twist on a loan with interest, as though this man said to the institution or to the bank: lend me the value of this product with the benefit of a particular, lend me the value of this commodity interest , but instead of the exhibits this behavior say: lend me the usefulness of this sale came Graphic trick on the loan is forbidden.
If this picture say: It is haraam, and it means that unfortunately exist in some institutions and banks.
Second case: do not get signed earlier between the man and the institution or the bank to complete the procurement process, but it gets a promise of such an institution or the bank that they buy those goods which promises this man that he would buy them, so the question is based on the promise of a non-binding. Comes to them and say: "I want to buy me a car Modelha as well as kind as well as for color as well, and I promise you if you bought with buy it from you.
What is the difference between this image and the first picture? First in a contract entered into a contract with them, here's what the contract promised only. He noted that the promise is not binding. Says: I bought this product and I promise I will buy it from you. This image may be subject to two conditions:
The first condition: that the initial agreement between a promise and a promise to sell to buy. This promise is a promise binding means that each has of the institution or the bank and the man's option for each option in the completion of such sale or not completed.
