Game of Drones: As U.S. Dithers on Regulations, Rivals Get a Head Start It's likely to be a year or more before the FAA's regulations are in place - good news for companies operating outside the U.S.

Drones, or unmanned aerial vehicles (UAVs), are a hot ticket in Silicon Valley, but U.S. government dithering over regulations has given overseas companies a head-start in figuring out how best to exploit them.

Global spending on drones could add up to close to $100 billion over the next decade, with commercial uses - from farming and filming to pipelines and parcels - accounting for around an eighth of that market, according to BI Intelligence.

But for years, the Federal Aviation Administration (FAA), the authority largely responsible for regulation in the United States, has dragged its feet, only last month issuing draft rules on who can fly drones, how and where. It's likely to be a year or more before the regulations are in place - good news for companies operating outside the U.S. and looking to build a business around drones.

Sky-Futures, a British company that dominates the use of drones to collect and analyze inspection data for oil and gas companies, says its business soared 700 percent last year as the normally conservative energy industry embraced the new technology. Co-founder and operations director Chris Blackford said the company is coupling drones with software and a better understanding of what works in the field, giving Sky-Futures "a head-start over the U.S because we understand pretty intimately the problems facing the oil and gas market, and how we can solve them with technology."

Looser regulations outside the U.S. have created pockets of innovation attracting ideas, money and momentum, says Patrick Thevoz, co-founder and CEO of Swiss-based Flyability, which builds drones inside a spherical cage that allows them to bump through doors, tunnels and forests without losing balance.

Another British company, BioCarbon Engineering, hopes to speed up reforestation by using drones to plant germinated seeds, and shares in New Zealand-based Martin Aircraft trebled in the first few days after listing in Australia last month, on investor hopes for the personalized aircraft maker which is developing a UAV that could be used by the military, oil and gas, mining and farming industries.

In Japan, the government is looking to fast track industry-friendly regulation to give its drone business an edge.

But the real work, say those in the industry, is in building out the drone ecosystem: the payload, software, operator and end user, and making sense of the data. That can only come by connecting to potential customers.

"As long as you don't have the end user because they can't use it, you're basically missing a lot of the ecosystem," says Thevoz.

In Singapore, Garuda Robotics is already moving beyond just being a drone operator. "The drones are a means to get the data out of the sky," says co-founder and CEO Mark Yong, "but if you can't process it you've not created any value for the customer."

While the company has been helping map the boundaries of palm oil plantations in Malaysia, it has added the ability to calibrate the drones' cameras to measure moisture levels in individual trees. It's now working with agronomists to figure out how to make sense of that thermal data to judge the health of trees and their likely yield.

Other projects include assembling real-time 3D maps of building sites to help construction schedules, monitoring and reducing algae blooms and keeping tabs on packs of stray dogs using infrared cameras.

All of this would be hard, if not impossible, under FAA regulations that limit drones flying out of sight of the operator, or at night.

While regulation typically lags technology, no one's betting against Silicon Valley dominating the industry in the long run. Last year, more than $100 million flowed into U.S. drone start-ups, according to CB Insights, double 2013 levels.

"Let's not kid ourselves," said Philip Von Meyenburg, who runs a drone operating company out of Singapore. "They know what they're doing in the U.S."

And China, too, is in the game as hardware prices fall rapidly. China's DJI sells consumer grade drones for $500, making it hard for companies producing lower volumes to justify their higher prices.

"The challenge for all drone manufacturers now is that we're in a market that is constantly updating," said Flyability's Thevoz.
