Volocopter: 18-propeller electric helicopter takes flight

German engineers celebrate as the Volocopter, one of the world's first electric helicopters, takes off on its maiden flight.

There's a lot to be said for determination. Two years ago, a contraption that looked a bit like a bouncy ball attached to a clothesline, took flight in a pioneering experiment in the German countryside.

A YouTube clip of a man flying the electric "Multicopter" attracted over 8 million hits, with comments ranging from: "AMAZING MACHINE!" to "Not sure you could pay me enough to sit in the middle of flying blenders bolted together."

Regardless, the three German engineers behind the baffling creation plowed ahead with their dream of making an electric helicopter. Last week it paid off.

  

 There wasn't a bouncy ball in sight as the slick white "Volocopter"took to the air for the first time, quietly hovering 20 meters high, while its ecstatic creators cheered below. Featuring 18 propellers on a lightweight carbon frame, the futuristic copter -- which has been around €4 million ($5.4 million) in the making -- could change the way we commute forever.

"Normal helicopters are very hard to fly. But we thought 'what if you could have a helicopter that is easy for the pilot to fly, and cheap compared to other aircraft?'" Clever copter Powered by a 100 kilogram battery, the two-passenger Volocopter can travel at least 70 kilometers per hour, recently making its first remote-controlled flight in a hanger in Karlsruhe, southwest Germany. The chopper weighs just 300 kilograms in total. One limitation is that it currently only has enough power to fly for 20 minutes -- though designers are looking at ways of increasing this, or introducing a hybrid engine.

 Many small rotors -- attached to a 10-meter wide circular frame -- also help the eco-friendly machine hover more easily than other helicopters. "If you let the joystick go, the Volocopter will just hover in the current position, so there's nothing the pilot has to do," said Wolf. "But if you do that in another helicopter it will crash immediately."

The European Union is already looking at ways personal aerial vehicles (PAVs) could revolutionize urban spaces. It might sound like a scene from the Jetsons, but a city where flying machines replace cars isn't as far off as it seems. "The most helicopters in the world are in Sao Paulo, Brazil," explained Wolf. "They have several thousand movements per day because the streets are congested and everyone who can afford it is taking the helicopter to go from one building to the next. "You can imagine this happening in a big city in Germany. And already we've been approached by several companies who'd like to do it, maybe with landing pads on buildings." The team hopes to sell its first Volocopter by 2015, with each machine setting you back €250,000 ($338,000). They're now on the lookout for further funding to develop their unique design.
