LOS ANGELES — A transportation company is betting its sleek new hydrogen-powered electric flying vehicles will someday serve as taxis, cargo carriers and ambulances of the sky, but experts say they will have to clear a number of regulatory hurdles before being approved for takeoff years in the future.
With six rotors on the roof and seats inside for five people, a passenger model of the Skai (pronounced “sky”) unveiled Wednesday near Los Angeles resembles an oversized drone crossed with a luxury SUV.
Like a drone, the vehicle from Alaka’i Technologies takes off and lands vertically. It’s one of many similar electric flying crafts in production, including prototypes from Boeing and Airbus that made successful test flights this year, according to Vertical Flight Society, an industry group.
The Skai uses very light hydrogen fuel cells to run its rotors, giving it a range of 400 miles (644 kilometers) and the capacity to carry 1,000 pounds (454 kilograms) in people or freight, the company says.
“We just couldn’t get to the point where we could have enough batteries to get to the payload that we knew we needed,” CEO Stephan Hanvey said of the choice to switch to hydrogen power.
Alaka’i says it’s planning a test flight near its Massachusetts headquarters.
It would be flown by an on-board pilot using a pair of joysticks, but the technology exists to eventually fly it remotely and even autonomously, Hanvey said.
It will be years before the Federal Aviation Administration allows the autonomous flight of passenger vehicles, said attorney Thaddeus Lightfoot, a partner with the firm Dorsey & Whitney who helps companies navigate FAA rules.
“The technology is interesting, but the regulatory road will be very long,” said Lightfoot, adding that the idea of allowing people to fly in a large aircraft without a pilot is “well outside the current regulatory regime.”
He hopes to see Skai aircraft used by first responders to send in food or water following disasters like hurricanes or wildfires that can destroy infrastructure.
It could be used as an ambulance and to evacuate people, Hanvey said. Outfitted with a transmitter, one could serve as a mobile cell tower, hovering for up to 10 hours over a neighborhood to provide communication services, he said. (AP)
