  • Intelligent.

  • Indestructible.

  • And with no humans on board,

  • these sail boats are plotting

  • their own course through the waters of San Francisco Bay.

  • If this guy gets his way,

  • soon there will be hundreds of them

  • trawling the ocean for data.

  • (electronic music)

  • This is Richard Jenkins.

  • And he's someone who likes a challenge.

  • Here he is trying to break the world record

  • for land sailing in 2009.

  • I registered at 116 miles an hour,

  • which I thought was kind of a low bar

  • and I could do it in maybe a year

  • and it was actually anything but easy.

  • Instead of one year, it took Jenkins

  • a decade of toiling in deserts around the world.

  • But break the record he did,

  • clocking just over 126 miles per hour

  • in his own custom designed vehicle.

  • The next challenge was a nod to Magellan

  • with a modern twist.

  • It encouraged me that nothing has ever gone

  • around the world unmanned and it's kind of the last

  • great records to get.

  • So Jenkins set out to build a robotic sailboat

  • capable of circumnavigating the globe.

  • In 2013, he sent the world's first unmanned vessel

  • across an ocean, going from San Francisco to Hawaii.

  • We actually called it the Honey Badger

  • because, you know, it doesn't give a shit,

  • it just plows through anything.

  • And somewhere, amidst all that,

  • he found the time to start a new business.

  • Based in this former aircraft hangar, in Alameda, California

  • Jenkin's company Saildrone has already raised

  • 90 million dollars from investors.

  • And here's what's got those venture capitalists so excited.

  • A 20 strong fleet of autonomous sea-worthy drones.

  • Who put the shark faces on them?

  • That was me, last weekend, I just freehanded that.

  • Powered only by the wind and sun,

  • these GPS guided bots can survive

  • at sea for months at a time.

  • Bristling with sensors, scientific equipment,

  • and cameras, they beam back real time data

  • and images via satellite from the ocean surface.

  • These two vehicles are on their way back from

  • a seven, almost eight month voyage.

  • Probably 10 thousand miles.

  • Where did they go?

  • Down to the Equatorial Pacific,

  • studying El Nino affects on the equator.

  • Right.

  • You wanna know what it looks like?

  • Is this the camera view?

  • Yes, this is a real time camera view.

  • And there it is, that's a picture from

  • Equatorial Pacific right now.

  • It's nice and sunny.

  • It's always sunny.

  • It's always sunny down there.

  • Right now, Saildrone is busy

  • prepping for a new mission.

  • The 2000 mile round trip to an area of Pacific Ocean

  • known as the white shark cafe.

  • Great White's come to this remote spot to hang out

  • for months at a time and scientists have spent decades

  • wanting to know why.

  • So we're working with Stanford University

  • to take these vehicles and literally follow the sharks

  • to the cafe to understand, literally,

  • what they're doing there.

  • Is it food, is it reproduction?

  • No one really knows.

  • The drones are ideal for missions like this.

  • They're much cheaper than large research ships

  • and can collect many different types of data.

  • PH, chlorophyll, humidity, radiation,

  • wind speed, direction, temperature,

  • the list goes on.

  • We measure everything you could possibly measure

  • near the surface of the ocean.

  • And data like this sheds light

  • on something that affects everyone.

  • The weather.

  • There really is infinite use for

  • more accurate weather and climate data.

  • So a big focus for us this year is deploying drones

  • into the hurricane field so we can find out how strong

  • they're going to be and where they're going to land.

  • And the impacts of that information is huge.

  • So for insurance risk, financial markets,

  • and for people's safety.

  • On an unmanned craft, hurricane force winds

  • would shred a conventional sail.

  • So instead, the drones harness the wind using the hard

  • vertical wing adapted from Jenkins' land sailing days.

  • When wind passes over an airplane wing, it produces lift.

  • In this case, the wind produces thrust that moves

  • the sail drone forward.

  • Jenkins invented a tail, with a small adjustable tab

  • to control this force.

  • It stops the wing from spinning out of control

  • and lets the robot make snap sailing decisions.

  • Everything about the craft is 100 percent

  • salt-water proof and submersible.

  • Today I'm hitching a ride to see Rich deploy

  • two of his drones to the white shark cafe.

  • There's not much wind so they're given a tow

  • into San Francisco Bay before being released.

  • There's enough wind here now we can start sailing.

  • We just left the city and this is where

  • we normally let them go.

  • Goodbye drone.

  • As soon as their released, they're on full autonomous mode.

  • You guys have gone 200 thousand nautical miles

  • without an incident?

  • Yep, we've had the drones operating for four years now.

  • And not a single scratch on the vehicle.

  • And nobody's every phoned it in as a, like a UFO

  • or some sailor's like what the hell are these things

  • doing out in the water?

  • No, they behave really predictably

  • and safely around ships.

  • And there are animals that come up and check them out?

  • Yep.

  • We got some really good pictures.

  • So, there's a spotted fur seal, jumped on for a ride

  • up in the Chukchi sea about 65 degrees north,

  • and hung out there for about six hours.

  • (electronic bubbly music)

  • These drones have a two week journey ahead of them

  • before they make their shark rendezvous

  • and soon, they'll be part of an even bigger fleet.

  • I want to get a thousand drones

  • within three to four years.

  • And that gives us full global coverage

  • so we have as much or better data of oceans

  • that we currently have for land

  • and that will transform our understanding of our planet.

  • (electronic fading out)

Intelligent.
