Watch this all-electric ‘flying car’ take its first test flight in Germany

April 24, 2017

 

Flying cars, that perennial dream for futurists that always seem to be at least five years away, may be a little closer to reality than we realize. A lot of prototypes have been showcased recently, and a lot of money is being tossed around. More people than ever seem to buy into the crazy notion that in the near future we’ll be buzzing between rooftops in private, autonomous drones. Today, Munich-based Lilium Aviation announced an important milestone: the first test flight of its all-electric, two-seater, vertical take-off and landing (VTOL) prototype.

In a video provided by the Munich-based startup, the aircraft can be seen taking off vertically like a helicopter, and then accelerating into forward flight using wing-borne lift.

The craft is powered by 36 separate jet engines mounted on its 10-meter long wings via 12 movable flaps. At take-off, the flaps are pointed downwards to provide vertical lift. And once airborne, the flaps gradually tilt into a horizontal position, providing forward thrust.

During the tests, the jet was piloted remotely, but its operators say their first manned flight is close-at-hand. And Lilium claims that its electric battery “consumes around 90 percent less energy than drone-style aircraft,” enabling the aircraft to achieve a range of 300 kilometers (183 miles) with a maximum cruising speed of 300 kph (183 mph).

In many ways, electric-powered aviation is still in its infancy. Electric cars with thousand-pound batteries generally max out at 300 miles per charge. The most sophisticated electric aircraft today can barely muster an hour aloft at 99 mph — and that’s without vertical take-off and landing. But Patrick Nathen, co-founder of Lilium Jet and the startup’s head of calculation and design, said their battery technology will get the job done.

“It’s the same battery that you can find in any Tesla,” Nathen told The Verge. “The concept is that we are lifting with our wings as soon as we progress into the air with velocity, which makes our airplane very efficient. Compared to other flights, we have extremely low power consumption.”

Safety is a major emphasis at Lilium, Nathen added. While the startup is working toward having its aircraft piloted autonomously, it intends to use human pilots in the meantime. There will be parachutes on board, and something called the “Flight Envelope Protection System” will prevents the pilot from performing maneuvers or flying the aircraft beyond safe flight parameters.

The plan is to eventually build a 5-passenger version of the jet. So anyone who dreams of a minivan version of the Jetsons’ flying car, this craft is for you. And naturally, Lilium envisions its aircraft used in dense, urban areas in an on-demand capacity. Pull out your smartphone, book a seat, and make your way to the nearest launchpad, which can be found at street level or on a nearby rooftop. Like Uber, but for flying cars (even though Uber is already working on its own version).And before you dismiss this as another luxury mode of transportation for the super-rich, Nathen insists the goal is to get the cost low enough so everyone can use it. A 55-minute taxi ride from Midtown Manhattan to JFK airport, with a fare of $55, becomes a breezy 5 minute flight in a Lilium jet, for as low as $6.

If it seems fantastical, it’s probably because it is. Flying cars, of course, are ridiculous. Wild-eyed inventors have been pursuing the idea for decades, with little to show for it. Many have gone broke, and some have died, trying to turn their fever dreams into reality. The fact that flying cars act as a stand-in for some distant, unattainable future isn’t a mistake. There are many things about flying cars that make them impractical, unworkable, and even wrongheaded. The problem is that these aircraft don’t solve any problems for normal human beings, nor do they even gesture toward a meaningful impact in the distant future. But that hasn’t stopped many from trying. And with better materials, autonomous navigation systems, and other technical advances, dozens of well-heeled investors are convinced that we’re on the cusp of seeing flying cars — or at least small, electric, autonomously flown commuter planes — take to the skies.

“We are right now at the magical point,” Nathen said. “We have without a doubt started at the perfect time… This is why you can see a lot of different projects from all over the world.”

Dave Brain: What a planet needs to sustain life

September 24, 2016

“Venus is too hot, Mars is too cold, and Earth is just right,” says planetary scientist Dave Brain. But why? In this pleasantly humorous talk, Brain explores the fascinating science behind what it takes for a planet to host life — and why humanity may just be in the right place at the right time when it comes to the timeline of life-sustaining planets.

Riccardo Sabatini: How to read the genome and build a human being

May 04, 2016

Secrets, disease and beauty are all written in the human genome, the complete set of genetic instructions needed to build a human being. Now, as scientist and entrepreneur Riccardo Sabatini shows us, we have the power to read this complex code, predicting things like height, eye color, age and even facial structure — all from a vial of blood. And soon, Sabatini says, our new understanding of the genome will allow us to personalize treatments for diseases like cancer. We have the power to change life as we know it. How will we use it?

Atlas, The Next Generation

March 03, 2016

A new version of Atlas, designed to operate outdoors and inside buildings. It is specialized for mobile manipulation. It is electrically powered and hydraulically actuated. It uses sensors in its body and legs to balance and LIDAR and stereo sensors in its head to avoid obstacles, assess the terrain, help with navigation and manipulate objects. This version of Atlas is about 5′ 9″ tall (about a head shorter than the DRC Atlas) and weighs 180 lbs.

Jeremy Howard: The wonderful and terrifying implications of computers that can learn

What happens when we teach a computer how to learn? Technologist Jeremy Howard shares some surprising new developments in the fast-moving field of deep learning, a technique that can give computers the ability to learn Chinese, or to recognize objects in photos, or to help think through a medical diagnosis. (One deep learning tool, after watching hours of YouTube, taught itself the concept of “cats.”) Get caught up on a field that will change the way the computers around you behave … sooner than you probably think.

Super Samurai: Robot beats Japanese master swordsman

May 16, 2015

Japanese engineers have come up with a robot that can copy the moves of a samurai sword master and then beat his “teacher” in a fight. The samurai machine carries out hard-angled cuts with speed and precision – without breaking sweat.

Among the robot’s most spectacular accomplishments is a party trick: being able to slice a runner bean lengthways.

The robot competed against renowned Japanese swordsman Isao Machii, from whom it learned how to fight by motion capturing his moves.

Machii can slice a fried shrimp fired at him at about 130 km per hour, according to The Independent, but he still lost his swordfight against the machine.

Robot arms, which have truly amazing skills, have recently entered the spotlight: one beat a world table tennis champion in March, while Russian military robots scored high at a shooting challenge a month ago during field training.

In April, a UK company unveiled a robo-chef capable of preparing meals from scratch.
