Hydrogen fuel cell flying car concept model released
A six-rotor concept flying vehicle designed by Arak Technologies of the United States, called Skai, uses hydrogen fuel cells instead of ordinary aircraft batteries to provide enough power, carry more weight, and fly longer. Recently, the company released the Skai model of the flying car in Los Angeles and plans to start testing the prototype as soon as possible.
Fuel cells utilize a chemical reaction between hydrogen and oxygen in the air to produce electrical energy and pure water. Since hydrogen can also be generated cleanly from water by electricity, a hydrogen fuel cell can effectively replace battery storage power. Hydrogen fuel cells are more expensive to manufacture than ordinary batteries, but they are smaller and lighter than regular batteries – which is critical to reducing the weight of electric aircraft.
Company president Brian Morrison pointed out that most ordinary battery-powered flying vehicles can only carry two passengers for about 15 minutes, while Skai with hydrogen fuel cells can carry 2.5 times the payload, and the flight time is to use ordinary batteries. 8 times the size - Skai can fly 400 miles with 5 or 1000 pounds of cargo, and the flight time is about 2-4 hours. “This means that Skai can fly between cities, assist in commuting, and can also undertake tasks such as air ambulance, cargo transportation or disaster relief.”
The Skai flight requires a qualified helicopter pilot to carry passengers. Now Akara Technologies is working with the Federal Aviation Administration (FAA) to drive passengers to fly autonomously.
Richard A. Anderson, a professor of aeronautical engineering at the University of Aberdeen, believes that hydrogen fuel cell vehicles are still not as good as ordinary aircraft engines, and to prevent explosions, hydrogen fuels must be handled with care. According to his prediction, the FAA has approved the listing of Skai for more than two years, and it may take more than five years for passengers to fly autonomously.
According to statistics, there are more than 100 types of design plans for flying vehicles, including the Vahana flying car of European Airbus, the Volocopter of the first pure electric two-ship helicopter in Germany, and the Elevate flying car of Uber in the United States.
