Article 1 : Heads Up! Drones will fly people around Dubai this summer.

By Kacey Deamer, Staff Writer

Commercial drones just got a big upgrade: A fleet of passenger-carrying quadcopters could be flying around the city of Dubai by this summer, according to news reports.

The city's new transportation option is an egg-shaped, single-passenger drone in the traditional quadcopter style seen in many commercial drones, the Associated Press reported. The Chinese-made Ehang 184 can carry one passenger weighing up to 220 lbs. (100 kilograms) and a small suitcase, according to the AP.

Mattar Al Tayer, head of Dubai's Roads and Transport Authority, said during the World Government Summit this week that the city plans to have the drone regularly traversing the city's skies in July.

"This is not only a model," Al Tayer told the AP. "We have actually experimented with this vehicle flying in Dubai's skies."

The drone was unveiled in a flight over Dubai's Burj Al Arab, the sail-shaped luxury hotel that is the fourth-tallest hotel in the world, the AP reported.

Once the passenger is buckled in and selects a destination, the drone automatically flies off. A control room will monitor the drones remotely via 4G mobile internet, according to the AP. With a battery that lasts for up to 30 minutes of flight and a range of up to about 30 miles (50 kilometers), the passenger-carrying drone can offer commuters an alternative to Dubai's notorious traffic. Though the drone can reach up to 100 mph (160 km/h), authorities said the drone's average operating speed will be about 60 mph (100 km/h), the AP reported.

Passenger-carrying drones are just the latest step in Dubai's vision for a technologically advanced transportation future. In April, the AP reportedabout United Arab Emirates Vice President and Prime Minister Sheikh Mohammed bin Rashid Al Maktoum's announcement that 25 percent of Dubai's commuters will be carried by driverless vehicles in 2030.

Following up on that claim, the city agreed to study the potential implementation of a "Hyperloop," a transportation system first envisioned by SpaceX and Tesla founder Elon Musk, according to the AP. In theory, the Hyperloop would move levitating pods through low-friction pipes to transport people at speeds as fast as 760 mph (1,220 km/h). For this project, Dubai partnered with Los Angeles-based Hyperloop One, which is not affiliated with Musk or his companies, to assess the possiblity of using a Hyperloop system to connect Dubai with Abu Dhabi.

Article 2 : Hyperloop: How the 760mph train will levitate above a magnetic track.

Hyperloop Transportation Technologies has revealed how its Elon Musk-inspired bullet train will levitate on a magnetic field as it blasts between stations at the speed of sound. The train will use a technology called passive magnetic levitation which its creators claim is more efficient and safer than the levitation system used by Maglev trains in Japan.

Where Maglev trains require many power stations to be installed along the side of the track, each feeding electricity to copper cables in the track, which become an electromagnet once charged, the Hyperloop system has a passive magnet on each train carriage and an aluminium track containing loops of wire. This setup is more like a pair of regular magnets, rather than an electromagnet which requires a constant supply of electricity to work.

Bibop Gresta, chief operations officer of Hyperloop Transport Technologies (HTT), explained how this system is better than Meglev. "Utilising a passive levitation system will eliminate the need for power stations along the Hyperloop track, which makes this system the most suitable for the application and will keep construction costs low."

Gresta continued: "From a safety aspect, the system has huge advantages, levitation occurs purely through movement, therefore if any type of power failure occurs, Hyperloop pods would continue to levitate and only after reaching minimal speeds touch the ground."

Where a power failure on a Maglev system would see the train fall into the rails at any speed (potentially hundreds of miles per hour), HTT's trains naturally levitate above the track at around 20mph and over; the theory is the same as that behind levitating Bluetooth speakers, which use two magnets facing each other to hold a speaker in the air above its base station.

The passive magnetic levitation system was developed by Dr Richard Post and his team at Lawrence Livermore National Labs, California, had has been exclusively licensed to HTT for use on the Hyperloop. The company says its floating trains can accelerate to 760mph between stations, faster than a commercial airliner. The trains will travel in a tube with almost all of its air removed, reducing drag and helping the carriages reach high speeds with minimal effort.

Costs are kept low by using solar power and recharging the onboard batteries through regenerative braking, a system also used by Formula One cars and electric vehicles like the Tesla Model S. HTT says construction on the Hyperloop starts later in 2016 and the first passenger service will begin in 2018.

HTT is not to be confused with Hyperloop Technologies, another company setting out to build a Hyperloop train. Both firms began work after Tesla CEO Elon Musk published a white paper in 2013 detailing how such a train might work. His plans described a train capable of taking passengers from Los Angeles to San Francisco, a journey of 350 miles, in 30 minutes. Musk says he will not be involved with building a Hyperloop, as his commitments lie with being CEO of Tesla and space transportation company SpaceX, and chairman of Solar City, a solar energy provider.


Resume :
Levitation is becoming increasingly important in the field of new technologies. It has a lot of advantages but its disadvantage is its price still too high.
The fact that the demonstration of the drone takes place in Dubai already asserts that only the wealthiest will be able to use it.

The advantage of these flying taxis is that they will no longer be influenced by traffic, and the journeys to our destination will take place more quickly. This system can push people to use more this flying taxi which can reduce pollution in the city.

The levitation train, as presented in Article Two is already marketed in Japan. It is very successful thanks to its speed and safety. Indeed it can no longer derail or have any other disagreement.

In the near future the levitation will grow and become more and more commercial. The skateboard is already well developed, the motorcycle and the car should soon appear on the market, but at what price?
