A Canadian team has finally won a cash prize on offer for 33 years for creating a human-powered helicopter. It works, but don't expect to ever see one like it on sale.

Finally, a human-powered helicopter

Thirty-three years ago, the American Helicopter Society offered an $10,000 reward to anyone who could build a human-powered helicopter.

Specifically the challenge was to create a flying machine that would be able to reach a height of three meters, fly for 30 seconds by human power alone, and stay in a 10 by 10 meter area.

Despite raising the award to its current $250,000, no-one has been able to accomplish this feat – until now.

A Canadian team from the University of Toronto finally snatched the prize this week.

The winning vehicle is called the Atlas, and was designed by a team of about 20 students and young professionals. They formed a company named AeroVelo with its first mission to win the cash prize.

The Atlas doesn't look like a helicopter. Since it is human-powered, it is extremely light just 55 kilograms – but it spans a sprawling 49.4 meters.

AeroVelo co-founder Cameron Robertson, 26, said the aircraft is designed to be ridden by someone 160 pounds or less. It also requires a fairly strong pedaler, requiring about one horsepower to operate, when the average person could probably manage a half horsepower, he said.

The winning June 13 flight was pedaled by team leader Todd Reichert, 31, an aerodynamics expert and competitive speed skater.
