Japan eager to get in plastic bracelets for eventson rise of "flying cars"The Benefits Of The Brodit Htc Desire Holder
TOKYO - Electric drones booked through smartphones pick people up from office rooftops, shortening travel time by hours, reducing the need for parking and clearing smog from the air.
This vision of the future is driving the Japanese government"s "flying car" project. Major carrier All Nippon Airways, electronics company NEC Corp and more than a dozen other companies and academic experts hope to have a road map for the plan ready by the year"s end.
"This is such a totally new sector Japan has a good chance of not falling behind," said Fumiaki Ebihara, the government official in charge of the project.
For now, nobody believes people are going to be zipping around in flying cars any time soon. Many hurdles remain, such as battery life, the need for regulations and of course safety concerns. But dozens such projects are popping up around the world.
The vehicles are often called EVtol, which stands for "electric vertical takeoff and landing" aircraft. All the flying car concepts promise to be better than helicopters, which are expensive to maintain, noisy to fly and require trained pilots, proponents say.
"You may think of Back to the Future, Gundam, or Doraemon," Ebihara said, referring to vehicles of flight in a Hollywood film and in Japanese cartoons featuring robots. "Up to now, it was just a dream, but with innovations in motors and batteries, it"s time for it to become real."
Google, drone company Ehang and car manufacturer Geely in China, and Volkswagen AG of Germany have invested in flying car technology.
Nissan and Honda said they had nothing to say about flying cars, but Toyota recently invested $500 million in working with Uber on self-driving technology for the ride-hailing service. Toyota group companies have also invested 42.5 million yen ($375,000) in a Japanese startup, Cartivator, that is working on a flying car.
The hope is to fly up and light the torch at the 2020 Tokyo Olympics, but it"s unclear it will meet that goal. At a demonstration last year, the device crashed after it rose to slightly higher than eye level. A video of a more recent demonstration suggests it"s now flying more stably, though it"s being tested indoors, unmanned and chained so it won"t fly away.
There are plenty of skeptics. Elon Musk, chief executive of electric carmaker Tesla Inc, said even toy drones are noisy and blow a lot of air, which means anything that would be "1,000 times heavier" isn"t practical.
"If you want a flying car, just put wheels on a helicopter," he said in a recent interview. "Your neighbors are not going to be happy if you land a flying car in your backyard or on your rooftop."
