Transcript: Ocean of Energy | Apr 28, 2015A fast clip shows wind turbines in the dusk sky, a solar panel farm, and a power plant with a chimney belching smoke into the sky.
The Narrator says THERE'S NO WAY AROUND IT.
WE NEED TO PUSH INNOVATION AND
INCREASE THE DEVELOPMENT OF
CLEANER, RENEWABLE SOURCES
OF ENERGY, AND REDUCE OUR
DEPENDENCE ON FOSSIL FUELS.
The fast clip continues with more scattered wind turbines on a hill, a row of wind turbines in the mountains, rows of solar panels and then large rocks jutting out of the beach.
The Narrator continues YET, NO SINGLE
ACCOMPLISH THIS CHALLENGE ON
WE NEED A MIX OF SUSTAINABLE
The fast clip continues and shows the beach and cliffs, the ocean crashing over rocks at the beach, and large waves on the ocean, and lastly a coastline cliffside with waves crashing into it.
A title appears it reads Ocean of Energy.
The Narrator continues WHAT IF ONE OF THE
MOST PREDICTABLE, UNTAPPED
SOURCES OF CLEAN ENERGY ALREADY
AND IS RIGHT OFF OUR SHORES?
HOW DO WE HARNESS THIS OCEAN
A title appears it reads Ocean of Energy. The title is on a background of waves and cliffs.
Tyler says HEY EVERYONE! I'M Tyler.
A fast clip shows Tyler, snowboarding, surfing, skateboarding, scuba diving and in a plane.
A caption reads Tyler.
Tyler is in his late twenties with brown hair and wears a green plaid shirt, and is clean shaven.
Tyler continues AND THIS IS MY YOUNGER BROTHER
A fast clip shows Alex water skiing, zip lining, swimming with sharks, and holding a fish.
A caption reads Alex.
Alex is in his late twenties with light brown hair and is not clean shaven. He wears a dark blue and green hoodie.
Alex says AND TOGETHER WE'RE THE
Then photos show Alex and Tyler in wetsuits and Alex with snorkels, Tyler with a camera near a glacier with Alex, and Tyler and Alex wearing red Mountie uniforms with brown hats, and holding fishing nets.
A fast clip shows the brothers canoeing on a lake, then sailing a boat, scuba diving in the ocean, then two fisherman throw their nets out into the water, a group of dolphins play in the ocean,
Alex continues WE'RE GOING TO
TAKE YOU ON AN ADVENTURE AROUND
THE WORLD TO EXPLORE THE STATE
OF OUR BLUE PLANET.
A PLANET DEFINED BY WATER
AND ITS ABILITY TO SUSTAIN LIFE.
The fast clip continues showing the two brothers in a speedboat, a woman pumping water, and another woman pulling water from a well.
Tyler says SO JOIN US ON OUR JOURNEY
AS WE EXPLORE THE WORLD,
LOOKING AT THE MOST IMPORTANT
WATER STORIES OF OUR TIME.
Alex says AND TOGETHER WE WILL LEARN
HOW TO BETTER PROTECT OUR
MOST PRECIOUS RESOURCE.
A title appears on screen it reads The Water Brothers.
A clip of the ocean showing tides and waves crashing appears, then changes to an ebb and flow of tides over a crystal clear ocean, and a surfer surfing down a huge wave.
The Narrator SAYS TIDES AND WAVES HAVE
BEEN STIRRING THE OCEAN EVER
SINCE IT FORMED AROUND THREE
POINT EIGHT BILLION YEARS AGO.
ANYONE WHO HAS WITNESSED THE
HUGE EBB AND FLOW OF THE TIDES
OR SURFED A GIGANTIC WAVE CAN
ATTEST TO THE INCREDIBLE ENERGY
FLOWING THROUGH THE OCEAN.
A fast clip shows an aerial view of the tides crashing into the rocks of an island, two people standing on the top of a cliff looking over the ocean, then waves, a power plant that belches its exhaust into the atmosphere, an aerial view of a two-tiered highway full of cars,a muddy beach next to the ocean, and one seagull flying alone above a stormy ocean.
Tyler narrates THE POSSIBILITY OF
CONVERTING THE POWER OF WAVES
AND TIDES INTO ELECTRICITY HAS
OF SCIENTISTS AND ENGINEERS.
YET, THE OCEAN HAD BEEN TOO
VOLATILE AND THE TECHNOLOGY TOO
EXPENSIVE TO COMPETE WITH
CONVENTIONAL SOURCES OF
NOW, AS THE IMPACTS OF CLIMATE
CHANGE ARE BECOMING MORE SEVERE
THESE ENDLESSLY CHURNING
WATERS ARE BEING RECONSIDERED
AS A VIABLE SOURCE FOR
RENEWABLE ENERGY GENERATION.
Dr. Peter Frankel is in his mid-sixties with white hair and eyebrows, and wears a black blazer with a striped blue and black shirt.
A caption reads Dr. Peter Frankel - Co-Founder - Marine Current Turbines.
A fast clip shows the moon in the night sky, then clouds moving over the beach as the tides ebb and flow while the sun sets,
Peter says THE MAIN
ADVANTAGE IS THAT IT'S
WITH WIND AND SOLAR, IT'S
OBVIOUS AT NIGHT THERE IS NO
WITH THE WIND YOU SOMETIMES GET
WITH TIDAL THOUGH, THE TIDES ARE
DRIVEN BY GRAVITY, NOT BY
AND THE GRAVITY FORCES OF THE
MOON AND THE SUN, INTERACTING
WITH THAT OF THE EARTH, ARE
FAR INTO THE FUTURE.
SO UNLIKE THE OTHER INTERMITTENT
OUTPUT FROM THE TIDAL TURBINE IS
AND THAT'S ACTUALLY QUITE A
A clip shows a view of waves crashing into cliffs. Then two people stand on the cliffs and look over the ocean, one man carrying a camera.
Alex narrates WITH ITS RUGGED
COASTLINES AND ROUGH SEAS,
THE WATERS SURROUNDING THE
UNITED KINGDOM ARE CONSIDERED A
PERFECT LOCATION FOR MARINE
RENEWABLE ENERGY GENERATION
AND AS A RESULT THE UK HAS
EMERGED AS THE BIRTHPLACE OF
THIS EXCITING NEW INDUSTRY.
A map of Europe and Asia focuses on Ireland and the UK. Then Belfast is underlined as well as Portaferry. A view of Strangford Lough shows a town with scattered houses, and gentle tide brushes up against green pastures. The tidal turbine sticks out of the water.
Tyler narrates IN A SMALL TOWN JUST
SOUTH OF BELFAST IN NORTHERN
IRELAND, A FULLY OPERATIONAL
TIDAL TURBINE LOCATED IN
STRANGFORD LOUGH HAS BEEN
TO THE LOCAL GRID SINCE 2008.
Alex appears and points to the tidal turbine. He wears a green jacket and a backpack.
Alex says TODAY WE'VE COME TO THE
TOWN OF PORTAFERRY TO SEE THIS,
THE SEAGEN DEVICE, THE WORLD'S
FIRST COMMERCIAL SCALE
A view shows the turbines.
Tyler narrates THE DAY WE ARRIVED
SEAGEN WAS UNDERGOING
REGULAR MAINTENANCE, GIVING
US A SPECIAL LOOK AT THE
TURBINE BLADES ABOVE THE
Alex says SO MATT, TELL US ABOUT THE
SEAGEN DEVICE, WHAT MAKES
THIS MACHINE SO UNIQUE?
Matthew Reed is in his mid-fifties, bald, and wears a blue jacket.
A caption below reads Matthew Reed. Engineering Director. Marine Current Turbines.
Alex and Matt stand on a boat viewing the turbines. The clip changes to a closer view of the turbines, and workers doing maintenance
Matthew says WELL IT'S A TIDAL
TURBINE GENERATOR, IT'S RATED AT
ONE POINT TWO MEGAWATTS, AND IT
WAS INSTALLED IN APRIL 2008,
AND IT'S HAD A PRESENCE IN
THE WATER SINCE THEN, AND IS
ELECTRICITY AND EXPORTING
THE POWER INTO THE GRID IN
A cartoon clip of the turbine shows the view below the water, where the turbines rotate slowly and create electricity.
Matthew says FUNDAMENTALLY, THE
ENERGY IS CAPTURED FROM THE
LARGE ROTOR BLADES THAT YOU SEE,
THAT PRODUCES A LOT OF TORQUE,
AND TURNS A HUB, ABOUT FOURTEEN
SO RELATIVELY SLOWLY, WE THEN
HAVE A GEARBOX,
WHICH INCREASES THAT TO A
THOUSAND RPM, WHICH TURNS A
GENERATOR, WHICH GENERATES
AND THAT'S SIMPLY FED INTO THE
Alex says SO IT'S MORE OR LESS LIKE
A WIND TURBINE UNDERWATER,
THE BLADES EVEN LOOK LIKE WIND
Matthew says THAT'S
EXACTLY WHAT IT IS.
THAT'S THE BEST WAY TO
UNDERSTAND HOW THE MACHINE
Alex, Tyler, Matthew and a cameraman stand on a speedboat and head towards the SeaGen.
Tyler narrates SEAGEN CAN GENERATE
ONE POINT TWO MEGAWATTS OF
ELECTRICITY, ENOUGH TO POWER
OVER ONE THOUSAND HOMES.
HOWEVER, THE STRENGTH OF TIDES VARIES THROUGHOUT THE YEAR
SO THE AMOUNT OF ELECTRICITY
GENERATED ALSO VARIES.
A cartoon clip shows planet Earth rotating, half of it covered in sunlight and the other half in darkness. Then the circular trajectory of the moon rotating around the Earth, and the sun shining on the sunny side of the Earth.
Alex narrates IT'S AMAZING TO THINK
THAT THE RHYTHMS OF THE OCEAN
ARE INFLUENCED SO STRONGLY BY
FORCES MILLIONS OF KILOMETRES
AWAY FROM EARTH.
The cartoon clip continues and underlines the Sun and the Moon. Blue shading shows the gravitational pull of the moon on the Earth and the red shading shows the suns gravitational pull on the Earth.
Tyler narrates AS THE EARTH SPINS,
THE GRAVITATIONAL FORCES OF THE
SUN AND MOON PULL ON THE OCEAN,
RAISING THE SEA LEVEL.
The cartoon continues, and low tide is highlighted in yellow and high tide in pink. High tide is a pink oval shadow that surrounds the Earth.
Tyler continues BEING MUCH CLOSER TO
EARTH THAN THE SUN, THE MOON'S
GRAVITY HAS A MORE DOMINANT
AS THE MOON PULLS WATER AWAY
FROM THE EARTH, A HIGH TIDE
OCCURS ON BOTH SIDES OF THE
PLANET AS THE EARTH IS ALSO
PULLED TOWARDS THE MOON,
CREATING THE OPPOSING
HIGH TIDE BULGE.
Alex appears looking into a camera and in a speedboat next to the SeaGen with Tyler, who stands behind the cameraman. Alex points to the rushing water.
Alex says WE JUST PULLED UP
ALONGSIDE THE SEAGEN, AND BEING
UNDERNEATH IT, YOU GET A REALLY
GOOD SENSE OF JUST HOW MASSIVE
THIS MACHINE IS AND HOW POWERFUL
THE TIDES ARE HERE.
THE WATER'S JUST RUSHING PAST
RIGHT NOW, BUT THIS IS ONLY A
NEAP TIDE SO IT'S ONLY ABOUT
HALF AS POWERFUL AS THE TIDES
WILL GET HERE.
A cartoon clip has a title that reads Neap Tides, and shows planet Earth next to the Sun and the Moon with a blue shadow that surrounds Earth. The moon then rotates around the Earth that is half in darkness and half in light.
Tyler says WHEN THE SUN AND MOON ARE PERPENDICULAR TO ONE
ANOTHER, THE DIFFERENCE BETWEEN
HIGH AND LOW TIDES IS AT ITS
LOWEST, CREATING NEAP TIDES.
BUT WHEN THE SUN AND MOON'S
GRAVITATIONAL FORCES ALIGN, THE
DIFFERENCE BETWEEN HIGH AND LOW
TIDES IS AT ITS GREATEST,
CAUSING SPRING TIDES.
The speedboat carries Tyler, Alex, and a cameraman. A map appears of Northern Ireland, and a light shines on Strangford Lough.
Alex says Engineers HAVE TO TAKE ALL THESE VARIABLES
INTO CONSIDERATION INCLUDING THE FACT THAT TIDES ARE
INFLUENCED BY GEOGRAPHY AND
CAN BECOME MORE PRONOUNCED
IN CERTAIN COASTAL AREAS LIKE
STRANGFORD LOUGH WHERE
FEATURES SUCH AS A NARROW
INLET AND SHALLOW WATER MAKE THE HEIGHT OF THE TIDES AND THE SPEED OF
THE CURRENTS EVEN STRONGER.
A view shows the Seagen and the tides rushing past.
Tyler narrates ALL THESE FACTORS
HELP MAKE TIDAL ENERGY VERY PREDICATBLE
BUT ONE CONCERN
WITH TIDAL TURBINES IS THE
POSSIBILITY THAT THE SPINNING
BLADES WILL STRIKE MARINE LIFE.
SO IN RESPONSE, A WILDLIFE
MONITORING PROGRAM HAS
BEEN SET UP WITH A LOCAL
A seal swims in a bay
A caption reads Jeremy and Simon Rogers. Maintenance Engineers. SeaGen.
Jeremy and Simon stand on a boat near the coast.
Jeremy says IF THERE'S
ANY REPORTS OF DEAD SEALS WASHED
UP ON THE SHORE, WE'VE HAD
TO LIFT THEM AND BRING THEM
UP TO THE LOCAL VETERINARY
CLINIC IN BELFAST TO GET AN
AUTOPSY, TO PROVE THE FACT THAT
SEAGEN ACTUALLY ISN'T
DOING ANY HARM.
A view of seals lying on the muddy shore.
Jeremy continues OUT OF ALL THE ONES THAT WE'VE
BROUGHT OUT, THERE HASN'T
BEEN ONE COME BACK YET TO SAY
THAT IT HAS BEEN HARMED
BY SEAGEN, IT'S BEEN NATURAL
A view of the SeaGen shows the speedboat floating below.
Tyler narrates ITS BELIEVED THAT DUE TO THE SLOW
ROTATION SPEED OF THE TURBINE BLADES ITS VERY
EASY FOR ANIMALS
TO AVOID BEING STRUCK.
ACTUALLY, MAINTENANCE ENGINEERS
HAVE NOTICED SOME POSITIVE
IMPACTS ON MARINE LIFE.
Jeremy and Simon stand on a boat in blue jackets. A view of the SeaGen appears and a closeup of mussels that are attached to the Seagen and birds circling above.
Jeremy says NOW TURNED INTO
AN ARTIFICIAL REEF, THERE'S A
MUSSEL BED GROWING REALLY ON
THE STRUCTURE OF SEAGEN
WHICH AGAIN, IS INVITING MORE
INVERTEBRATE LIFE TO
GROW THERE, WHICH INVITES
THE BIGGER ANIMALS TO COME
AND FEED ON THOSE, AND THE BIRD
Simon scoops up mussels in his hands.
SIMON says AND IT MAKES A NICE
DINNER FOR US IN THE EVENING
AS YOU'RE GOING OFF, YOU JUST
GRAB A HANDFUL
OF MUSSELS, JUST AS YOU'RE
YOU CAN'T GET THEM ANY FRESHER
A cartoon shows the SeaGen with a caption that reads SeaGen 2.0 There Blade Turbine Design. Its blades appear turning underwater.
Matt says THE SEAGEN MACHINE HAS
PROVED THAT THE ACTUAL
IT'S TAUGHT US PLENTY OF LESSONS
ALONG THE WAY,
WHICH WE'VE BEEN ABLE TO LEARN
FROM AND RECTIFY AND
GET THE MACHINE RUNNING
SO IT'S BEEN A REALLY, REALLY
GOOD LEARNING EXPERIENCE,
AND WE THINK THAT WILL BE THE
SPRING BOARD INTO WIDER
DEPLOYMENT OF THIS TECHNOLOGY
WITH FARMS COMING UP IN THE
A map of the UK hows the Orkney Islands underlined, and the islands themselves highlighted in red.
Tyler narrates THE SUCCESS OF THIS
ENTERPRISE IS A POSITIVE SIGN
FOR THE TIDAL ENERGY INDUSTRY
AND TO GET A SENSE OF WHAT THE
FUTURE HOLDS FOR THESE
TECHNOLOGIES THERE IS NO BETTER
PLACE TO GO THAN THE REMOTE
ORKNEY ISLANDS IN SCOTLAND.
A fast clip shows the Orkney Islands: row houses, a woman walking a pony with two dogs, green pastures, neolithic standing stones, one single turbine on a hill, then a single wind turbine in a pasture of sheep and scattered houses that are close to the coast, a view of Orkneys coast with waves thrashing the cliffs, then a wind turbine being lifted and inspected.Alex narrates PEOPLE HAVE BEEN
LIVING IN ORKNEY FOR OVER
EIGHTY-FIVE HUNDRED YEARS
AND ANCIENT NEOLITHIC SITES ARE SCATTERED ACROSS THE ISLANDS.
BUT TODAY THE ISLANDS ARE
GETTING INTERNATIONAL ATTENTION
FOR THE DEVELOPMENT OF STATE
OF THE ART ENERGY TECHNOLOGY.
ORKNEY'S EXPOSED, RUGGED
COASTLINES WITH STRONG
CURRENTS AND WINDS MAKE IT
THE PERFECT HOME FOR THE
EUROPEAN MARINE ENERGY
CENTRE OR EMEC.
Tyler says STARTING IN 2003,
COMPANIES FROM AROUND THE WORLD
HAVE DESCENDED ON ORKNEY TO
TEST PROTOTYPES FOR HARNESSING
MARINE RENEWABLE ENERGY LIKE THIS TITLE TURBINE.
EMEC HAS BUILT INFRASTRUCTURE
SO THAT DEVICES CAN BE
CONNECTED TO THE LOCAL POWER GRID
BECOME ONE HUNDRED PERCENT
POWERED BY RENEWABLE ENERGY.
Tyler and Alex stand and look at the wind turbine on a dock.
Neil is in his mid-sixties, bald and clean-shaven, and wears a blue jacket over his white shirt and tie. The coast and the EMEC facilities are in the background.
The scene changes and a caption reads Neil Kermode. Managing Director. EMEC.
NEIL says WE'VE DONE
IT, WE'VE DONE IT HERE.
WE GENERATED FROM WAVE
ENERGY IN 2004, FIRST TIME
ANYWHERE IN THE WORLD THAT
HAD BEEN DONE.
2008, WE HAD A TURBINE HERE
GENERATING FROM THE TIDES, FIRST
TIME IN THE UK.
SO WE'VE SPLIT PEOPLE APART
FROM THOSE WHO
DON'T BELIEVE IT'S GOING TO
WORK AND THOSE WHO DO.
AND NOW WE'VE ACTUALLY SHOWED
THEM THAT IT REALLY IS WORKING.
A cartoon clip shows waves in the distance and green buoys used as a way to trap wave energy.
Tyler narrates TECHNOLOGIES
AT EMEC COME IN ALL SHAPES AND
SIZES AND SOME OF THE MOST
FASCINATING AND UNUSUAL DESIGNS
ARE THE MANY DEVICES USED
TO CAPTURE WAVE ENERGY.
Alex speaks on the boat and then the boat propellers appear turning as they head to Pelamis.
Alex says SO WE'VE LOADED UP THE
BOAT, AND WE'RE ABOUT TO GO SEE
THE PELAMIS WAVE ENERGY DEVICE
AND WE'RE REALLY EXCITED TO
LEARN HOW THIS MACHINE IS ABLE
TO HARNESS THE POWER OF WAVES.
Joe Thompson appears. He is in his early thirties with brown hair, and wears a orange jacket and red vest. A view of Pelamis shows it is red and yellow, and is a long tube buoyed in the ocean by the turbines below.
Tyler narrates Joe THOMPSON IS THE
OPERATIONS ENGINEER FOR THE
PELAMIS P2, A WAVE ENERGY
MACHINE APPROPRIATELY NAMED
AFTER A SPECIES OF SEA SNAKE.
Alex says SO HOW DOES THE MACHINE
ACTUALLY CAPTURE WAVE ENERGY?
A cartoon clip shows Pelamis on the water, then a closeup of how Pelamis functions. Hydraulic rams move in and out, pressurising the oil that moves through the generators on the machine, creating electricity that is sent back to the substation via cables on land.
Alex and Joe sit in the boat, with Pelamis behind them.
A caption reads Joe Thompson. Operations Engineer. Pelvis Wave Power.
Joe says SO AS YOU CAN SEE HERE,
WITH THE MACHINE, IT'S GOT FOUR
JOINTS ON IT AND AS THE WAVE
MOVES ALONG THE MACHINE IT
MOVES THE SEPARATE SECTIONS
AND THE JOINTS MOVE LIKE THIS.
AND IN EACH JOINT THERE ARE FOUR
HYDRAULIC RAMS, WHICH WILL THEN
BE MOVED IN AND OUT AT VARIOUS
POINTS OF THE MACHINE;
IT CAN ALSO MOVE SIDE TO SIDE.
AND THEY PRESSURIZE OIL, WHICH
THEN IS FED THROUGH
GENERATORS ON THE MACHINE.
SO THE MACHINE GENERATES
ELECTRICITY ON BOARD AND
CONDITIONS IT AND THEN SENDS IT
VIA CABLE, WHICH GOES ALONG THE
SEABED, BACK TO LAND, BACK TO
Alex says SO IT'S CONNECTED TO
Joe says YEP, THIS IS GENERATING
ELECTRICITY TO THE NATIONAL
GRID RIGHT NOW.
A close up view shows Pelamis from front to rear.
Joe continues THIS MACHINE HERE IS
RATED FOR 750 KILOWATTS, WHICH
MEANS IT CAN GENERATE UP TO
750 KILOWATTS ANYTIME, WHICH
YOU COULD PROBABLY COMPARE
TO A MEDIUM-SIZED WIND TURBINE.
Tyler says THE PELAMIS IS ABLE TO POWER AS MANY AS FIVE HUNDRED HOMES AND THIS LATEST VERSION IS
BEING PUSHED TO THE LIMITS
IN THE TURBULENT SEA CONDITIONS
OF ORKNEY TO DETERMINE JUST HOW
EFFICIENT THIS TECHNOLOGY
Alex says SO WHAT MAKES WAVE
ENERGY SUCH A GREAT FORM OF
ENERGY TO CAPTURE?
A cartoon clip shows an underwater view of Pelamis as well as an aerial view of two wave energy machines.
Joe says THE WAVES OFTEN COME AS
DIFFERENT TIMES THAN THE WINDS,
SO WHEN YOU GOT WIND POWER, YOU
WILL HAVE WAVE POWER, BUT
WHEN THE WIND GOES AWAY, THE
WAVES WILL PROBABLY STILL BE
THERE FOR QUITE SOME TIME,
SO YOU CAN RELY ON THE FACT
THAT YOU WILL HAVE A GOOD
MIX OF ENERGY, WHICH HELPS
FOR ENERGY SECURITY.
Tyler says ALTHOUGH WAVE
BEHAVIOUR IS INCONSISTENT AND
HARNESSING WAVE ENERGY IS
NORTHERN SCOTLAND REMAINS A
PERFECT PLACE TO FURTHER
ADVANCE THIS PROMISING
A clip shows Alex and Joe talking on the boat, with Pelamis in the background.
Alex says AND I HEAR THAT WHEN
YOU'RE NOT WORKING ON THE WAVE
POWER DEVICE, YOU ALSO LIKE TO
PLAY IN THE WAVES AS WELL.
The clip changes to Alex, Tyler, and Joe, with their surfboards and wetsuits walking along the coast and then heading into the water.
Joe says YEAH, I'M AN AVID SURFER,
SO I WORK AND PLAY IN THE WAVES.
I'VE BEEN SURFING FOR TWELVE
YEARS AND I SUPPOSE THAT'S PART
OF THE ATTRACTION OF WORKING
IN WAVE POWER IS YOU
GET TO BE BY THE SEA.
WHAT'S A BETTER WAY TO FIND OUT
WHAT THE POWER OF THE WAVES
IS THEN TO GO OUT IN THEM
All three surf the waves. Then the clip ends with Alex with his surfboard next to the coast, and a view of the ocean from the shore at dusk.
Alex says OH MAN, THAT WAS SO MUCH
FUN, I'M EXHAUSTED.
BEING OUT THERE, GETTING
PUMMELLED BY THE WAVES, REALLY
DOES SHOW YOU THOUGH, HOW
POWERFUL WAVE ENERGY REALLY IS.
AND IT'S AMAZING TO THINK THAT
THE WAVES WE WERE RIDING
HAVE COME ALL THE WAY FROM
THE OTHER SIDE OF THE
ATLANTIC, THOUSANDS OF
IT'S SUCH A MASSIVE SOURCE OF
RENEWABLE ENERGY JUST WAITING TO
IMAGINE IF WE COULD CAPTURE JUST
A FRACTION OF IT.
A fast clip shows a miniature wind turbine in the water, then it changes to Alex and Tyler walking to see the FloWave. An aerial view of the FloWave shows a green pool with a fenced-in grey edge.
Tyler narrates EMEC PLAYS AN ESSENTIAL ROLE
OPTIMIZE THEIR DESIGNS FOR
BUT BEFORE MACHINES CAN BE TESTED IN
THE OCEAN, DEVICES ARE PUT
THROUGH THEIR PACES AT THE
SMALLER MODEL SIZE SCALE.
SO WE WENT TO THE UNIVERSITY OF
EDINBURGH TO CHECK OUT THE
FLOWAVE THE MOST ADVANCED
MARINE ENERGY TEST TANK
IN THE WORLD.
Alex, Tyler and Stuart walk around FloWave, which creates waves and tides.
Alex says FLOWAVE'S CEO, STUART
BROWN, WAS ON HAND TO SHOW
US HOW THE WORLD'S MOST
EXPENSIVE WAVE POOL IS ABLE TO
CREATE BOTH WAVES AND TIDES AT
THE SAME TIME.
Tyler narrates WITH ITS UNIQUE
CIRCULAR SHAPE AND 168
WAVE-MAKERS WORKING IN TANDEM,
THE FLOWAVE CAN PUSH WAVES AND
CURRENTS TOWARDS DEVICES
FROM EVERY ANGLE, MIMICKING
Alex and Stuart stand by the FloWave and chat. A view shows the panels of the FloWave machine and the waves that are created.
Stuart Brown is in his mid-forties and has brown hair. He wears a grey sweater, blue jeans, and a blue shirt with glasses.
A caption reads Stuart Brown. CEO. FLOWAVE.
Stuart says THIS IS EFFECTIVELY
LIKE A STEPPING-STONE.
WHEN YOU HAVE SMALL SCALE
TESTING, MAYBE ONE-HUNDREDTH
SCALE MODELS, TO TEST AND PROVE
CONCEPTS, IT'S A HUGE LEAP TO GO
FROM THERE TO TESTING SOMETHING
IN STEEL, IN THE REAL SEA.
IT'S EXPENSIVE IN TERMS OF THE
CONSENTING, IN TERMS OF THE
VESSELS YOU NEED TO HIRE,
AND SO ON.
SO THIS IS A WAY OF TESTING IT
AT LARGE MODEL SCALE, TO
REFINE THOSE DEVICES, TO GET
THE RISK OUT, AND BASICALLY
MAKE YOUR MISTAKES
RELATIVELY CHEAPLY BEHIND
CLOSED DOORS, IN A VERY
A computer sits on a table next to FloWave. The FloWave creates one large wave.
Tyler narrates TO GIVE US A SAMPLE OF HOW POWERFUL AND PRECISE
THE MACHINE IS THEY SHOWED US
HOW THEY PUSH THE FLOWAVE
TO ITS LIMITS TO CREATE A
ONE-TON BLAST OF WATER CAPABLE
OF CRUSHING A CAR.
Alex says(LAUGHTER) WOW.
Stuart says HOW COOL IS THAT?
Alex says THAT'S SO COOL. (LAUGHTER)
Stuart says IT'S A VERY
IT'S A HUGE PIECE OF
ENGINEERING, BUT MOST
IMPORTANTLY IT REALLY WILL
SOLVE SOME OF THOSE BIG
INDUSTRY CHALLENGES AND
ISSUES, ABOUT PERFORMANCE,
ABOUT RELIABILITY, AND THAT
LEADS INTO BANKABILITY, AND
FINANCE-ABILITY AS WELL.
An aerial view of the wave machine shows the fountain of water in the centre of the machine. A clip shows a power plant and the exhaust it expels into the atmosphere, and then a view of a smog-filled port.
Tyler narrates WITH TIDAL AND
WAVE ENERGY TECHNOLOGIES
STILL IN EARLY STAGES OF
DEVELOPMENT THE INITIAL COSTS
CAN BE EXPENSIVE FOR DEVELOPERS
BUT THESE COSTS MUST BE WEIGHED
AGAINST THE OFTEN UNACCOUNTED
FOR BENEFITS OF REDUCED AIR
POLLUTION AND ITS EFFECTS ON
Alex says BUT AS TESTING
FACILITIES LIKE FLOWAVE HELP
AND AS MORE DEVICES ARE INSTALLED
AROUND THE WORLD COSTS
ARE EXPECTED TO FALL QUICKLY.
THE NEXT BIG CHALLENGE IS TO
DETERMINE JUST HOW WIDESPREAD
MARINE RENEWABLES COULD BECOME.
A fast clip shows a view of SeaGen in front of marshlands near the coast, and a seal swimming in the ocean
Peter says WE DON'T
ACCURATELY KNOW HOW MUCH TIDAL
ENERGY THERE IS BECAUSE MOST OF
THE LOCATIONS WHERE THERE ARE
POSSIBILITIES HAVE NEVER
BEEN SURVEYED PROPERLY.
WE DO HAVE A PRETTY GOOD IDEA
OF THE UK'S RESOURCE, AND WE
THINK IT'S IN THE REGION OF
ABOUT TEN PERCENT OF PRESENT
DAY ELECTRICITY DEMAND, THAT
WOULD EQUATE TO ABOUT FIVE
TO TEN GIGAWATTS OF INSTALLED
The fast clip continues with the clouds moving over the beach and the ocean.
Peter continues AND I
BELIEVE THE REST OF THE WORLD IS
PROBABLY, TO GIVE A VERY
ROUND NUMBER, ABOUT AN ORDER
OF MAGNITUDE MORE, IN OTHER
WORDS, ABOUT TEN TIMES THE UK.
AND YOU MAY BE INTERESTED I
THINK, THE OTHER COUNTRY WHICH
HAS A PARTICULARLY GOOD RESOURCE
A map of the Earth shifts to Canada. The word Canada is written in large letters. An aerial clip shows the Bay of Fundy which has cliffs, coasts, and beaches.
Tyler narrates WITH THE WORLD'S
LONGEST COASTLINE AND COUNTLESS
INLETS AND BAYS, CANADA IS A
PERFECT FIT FOR A TIDAL ENERGY
INDUSTRY AND THE MOST EXCITING
STUDIED TODAY IS THE BAY OF
FUNDY, HOME TO THE LARGEST
TIDAL RANGES IN THE ENTIRE
Alex stands in front of the Barrage System set up on the coast of Nova Scotia.
Alex says PEOPLE HAVE BEEN TRYING TO
THINK OF WAYS TO GENERATE
ELECTRICITY FROM THE BAY OF
FUNDY FOR WELL OVER A
BUT IT WASN'T UNTIL 1984 THAT
NOVA SCOTIA BUILT THIS
THE ANNAPOLIS ROYAL
TIDAL GENERATING STATION.
Alex continues IT'S CALLED A TIDAL
BARRAGE SYSTEM AND IT WORKS
A LOT LIKE A HYDROELECTRIC DAM.
BUT THESE SYSTEMS HAVE
A FEW LIMITATIONS.
THERE ARE VERY FEW PLACES YOU
CAN BUILD THEM, AND WHEN YOU DO,
THEY SOMETIMES TRAP MARINE LIFE
THAT SWIM THROUGH THE GATES.
BUT THANKFULLY, TIDAL TECHNOLOGY
HAS COME A LONG WAY IN THE PAST
THIRTY YEARS AND NOVA SCOTIA IS
ON THE VERGE OF REVOLUTIONIZING
THE WAY THEY GENERATE
ELECTRICITY FROM THE TIDES.
A fast clip shows an aerial view of a bay, then the coast with a forest and the ocean.
A map of Canada and the USA appears. Then an aerial view of the Bay of Fundy that lies between Maine, New Brunswick and Nova Scotia.
Tyler narrates THANKS TO
ADVANCES MADE AT RESEARCH
FACILITIES LIKE EMEC, IN-STREAM TIDAL
TURBINE TECHONOLOGY FINALLY
SEEMS READY TO TAKE ON THE
CHALLENGE OF HARNESSING THE
MOST POWERFUL TIDAL SYSTEM
IN THE WORLD.
A spotlight shines as and waves funnel through the bay.
Alex narrates THE RECORD BREAKING
BAY OF FUNDY TIDES ARE A RESULT
OF ITS UNIQUE SHAPE AND DEPTH
FORMING A FUNNEL LIKE STRUCTURE
THAT IS JUST THE RIGHT LENGTH
TO MAXIMIZE TIDAL RANGE.
AS THE HIGH TIDE FLOWS INTO THE
MOUTH OF THE BAY,
IT TAKES ROUGHLY SIX HOURS FOR THAT WATER
TO FLOW TO THE TIP OF THE BAY
AND BACK OUT AGAIN,
MATCHING UP ALMOST PERFECTLY WITH THE EBB
AND FLOW OF TIDES ACROSS THE
A fast clip shows high tide and low tide in the bay.
Tyler narrates THE DIFFERENCE
BETWEEN HIGH AND LOW TIDES IN PARTS OF THE BAY CAN BE LARGE
ENOUGH TO COVER A FIVE-STOREY
BUILDING AND DURING THE TWELVE
AND A HALF HOUR TIDAL CYCLE,
OVER 115 BILLION TONS OF WATER
FLOW IN AND OUT OF THE BAY.
Doctor Richard Karsten appears. He is in his mid-forties, wears glasses, and has shoulder length brown hair. He wears a blue blazer and a blue and white striped shirt. He sits in a chair at an oval table.
A caption reads Doctor Richard Karsten. Department of Mathematics. Acadia University.
Richard says THE AMOUNT OF
WATER THAT'S GOING THROUGH THERE
WE CALCULATED, WHEN IT'S FLOWING
AT FLOOD TIDE, IS ROUGHLY THE
SAME AMOUNT OF WATER AS ALL THE
RIVERS IN THE WORLD COMBINED.
SO RIGHT OUTSIDE IN MINAS
PASSAGE THERE, WE HAVE MORE
THAN THE AMAZON, IT'S ABOUT
TWO AND A HALF, THREE TIMES
WHAT THE AMAZON RIVER IS
FLOWING AT ANY GIVEN POINT.
SO THIS IS A HUGE AMOUNT OF
WATER GOING THROUGH THERE.
A clip shows the beach with the ebb and flow of the tide. Then it changes to sea-birds at the beach.
Alex narrates THIS MASSIVE MOVEMENT
OF WATER AND NUTRIENTS SUPPORTS
A RICH ECOSYSTEM OF
FISH, CRUSTACEANS, MAMMALS AND
MILLIONS OF MIGRATORY SEABIRDS.
Tyler appears in the bay with two rafts, the beach, and the forest beyond it in the background.
Tyler says THERE ARE SO
MANY AMAZING NATURAL WONDERS TO
SEE IN THE BAY OF FUNDY, BUT ONE
OF THE COOLEST ONES TO
EXPERIENCE IS KNOWN AS A TIDAL
BORE, AND THIS OCCURS WHEN
THE TIDES MEET LARGE RIVERS, AND
WHEN THESE TWO FORCES OF WATER
MEET, THEY CREATE MASSIVE
WAVES THAT PEOPLE LOVE TO WHITE
WATER RAFT ON.
SO TODAY WE'RE GOING TO GET OUT
ON THE WATER AND EXPERIENCE THE
TRUE ENERGY IN THE TIDES.
An aerial view shows a single raft in the Bay of Fundy, then it changes to two motorboats that cruise up the river, one with Tyler and Alex
Alex narrates THE SHUBENACADIE RIVER NEAR THE CITY OF TRURO,
NOVA SCOTIA HOSTS ONE OF THE
MOST UNUSUAL RIVER RAFTING
EXPERIENCES IN THE WORLD. TWICE A DAY A TIDAL BORE FORCES
ITS WAY UP THIS RIVER
SYSTEM FOR OVER THIRTY
KILOMETERS AND IS SO FAST
AND POWERFUL IT CAN ONLY BE
RIDDEN FOR LONG PERIODS
USING A MOTORBOAT.
Alex has a camera in his hand on the boat, and Tyler and Alex get soaked by the tide waves.
Alex continues EVEN THOUGH IT IS TOO SHALLOW HERE
TO CAPTURE THE
TURBINE, IT IS A PERFECT
EXAMPLE OF JUST HOW POWERFUL
THE BAY OF FUNDY TIDES ARE.
WITH SO MUCH ENERGY FLOWING
RIGHT THROUGH THE BACKYARDS OF
OVER A MILLION CANADIANS, IT
MIGHT SEEM SURPRISING
THAT A TIDAL ENERGY INDUSTRY
HASN'T ALREADY TAKEN OFF HERE.
BUT THE INCREDIBLE STRENGTH OF
THESE TIDES PRESENTS A
Alex and Tyler walk together and enter FORCE. A map shows Maine, New Brunswick, PEI and Nova Scotia. Parrsboro, Nova Scotia is underlined.
Alex narrates ONE GROUP THAT IS
HELPING MAKE THIS DREAM A
REALITY IS THE FUNDY OCEAN
RESEARCH CENTRE FOR ENERGY, ALSO KNOWN AS FORCE, LOCATED NEAR THE
TOWN OF PARRSBORO, NOVA SCOTIA.
A boat picks up Tyler and Alex. Alex and Matt both wear red safety vests, Alex wears a green coat and Matt a grey coat, and they look towards the future location of the Tidal turbines.
Tyler says WE MET WITH MATT
LUMLEY WHO TOOK US TO THE SITE
WHERE FORCE IS PLANNING TO INSTALL TIDAL TURBINES THAT WILL
BE HOOKED UP TO NOVA SCOTIA'S
Alex says SO WE ARE RIGHT NEAR THE
TEST SITE AND THIS IS
BLACK ROCK, YOU WERE SAYING, YOU
CAN SEE THE WATER
RUSHING RIGHT BY US.
Matt appears and he is in his mid-forties, clean-shaven, with dark brown hair.
A caption reads Matt Lumley. Communications Director. Force.
Matt and Alex sit on the boat with the bay in the background.
Matt says YEAH IT'S INCREDIBLE.
RIGHT NOW, WE ARE GOING SIX OR
SEVEN KNOTS JUST TO
SO, IN OTHER WORDS, WE'RE
BURNING ALL THIS FUEL TO
STAY IN ONE PLACE AND
EFFECTIVELY WHAT TIDAL
ENERGY IS DOING, WITH AN
UNDERWATER WINDMILL ANCHORED
TO THE SEAFLOOR, IS COLLECT ALL
A view shows the bay, its cliffs, and a strong current.
Tyler narrates IN 2009, NOVA
SCOTIA'S FIRST TIDAL TURBINE
PROTOTYPE WAS DEPLOYED AT THIS
SITE BUT ENGINEERS UNDERESTIMATED JUST HOW POWERFUL
THE TIDAL CURRENTS REALLY WERE.
Matt says IT LASTED THROUGH ONE
SPRING TIDE AND THEN ON THE
SECOND SPRING TIDE, ACTUALLY THE
SECOND BIGGEST SPRING TIDE
OF THE YEAR, THE BLADES BLEW
SO THERE IN A NUTSHELL IS BOTH
THE CHALLENGE AND THE
WE ARE WORKING WITH A SITE THAT
HAS EQUIVALENT TO CLASS FOUR
HURRICANE TIDAL CURRENTS.
SO ENORMOUSLY POWERFUL, BUT ALSO
IF YOU CAN HARNESS THAT ENERGY
THE POTENTIAL HERE IS RICH.
AS WE'VE DEVELOPED THE SITE
OVER THE LAST FEW YEARS WE NOW
HAVE A MUCH BETTER UNDERSTANDING
OF WHAT YOU REALLY HAVE
TO DESIGN FOR.
Alex says SO IF YOU CAN GET A
TURBINE TO WORK RIGHT HERE YOU
CAN GET IT TO WORK ANYWHERE,
A clip shows several high rises and a ferry boat on the river, a street full of cars in the middle of the city, an aerial view of the coast and a bay.
Matt says YEAH. OUR GOAL IS TO SEE
20 MEGAWATTS IN THE WATER
NOVA SCOTIA'S GOAL IS TO TENDER
FOR AN ADDITIONAL 300 MEGAWATTS,
STARTING ABOUT THAT TIME, AND
THE ACTUAL POWER POTENTIAL IS UP
AROUND 2500 MEGAWATTS.
AND THAT'S LARGER THAN THE
GREATEST PEAK DEMAND IN
Alex says SO MORE POWER THAN ALL OF
NOVA SCOTIA CURRENTLY USES
AT THEIR PEAK DEMAND.
Tyler, Alex and Matt get off the boat and cross the beach.
Matt says EXACTLY RIGHT.
Alex SAYS WOW.
THE WORK BEING DONE BY FORCE IS ESSENTIAL FOR HELPING
NOVA SCOTIA MEET ITS GOALS FOR
TIDAL POWER GENERATION
BUT FORCE IS NOT THE ONLY
GROUP WORKING TO MAKE THESE
DREAMS A REALITY.
Then a view of an abandoned house leads to Greg, Tyler and Alex in red suits crossing a dock, then getting onto a motorboat.
Tyler says GREG TROWSE IS AN
ENGINEER FOR FUNDY TIDAL, A
COMPANY THAT IS PLANNING TO install smaller turbine projects
THAT WOULD BE OWNED AND
OPERATED BY COASTAL
Tyler narrates WE JOINED HIM FOR
TESTS AT A POTENTIAL TURBINE
Alex and Greg appear on the motorboat.
Greg is in his mid-thirties with a beard, and wears a reversed baseball cap.
A caption reads Greg Trowse. Chief Technology Officer. Fundy Tidal.
Alex says SO GREG, TELL US ABOUT
THESE DEVICES HERE, AND WHAT WE
ARE GOING TO BE DOING TODAY.
Greg says OKAY, THESE ARE LOW
PROFILE SURFACE DRIFTERS.
SO WE'LL PUT THESE IN THE WATER,
IT'S GOT A GPS IN IT AND IT'S
GOING TO MEASURE FLOW SPEED AND
DIRECTION ALL ALONG ITS TRACK.
SO WHAT WE'LL DO IS DEPLOY
THEM ACROSS THE CHANNEL HERE
AND WE'LL PICK THEM UP
DOWNSTREAM AND REPEAT THAT
THROUGH THE TIDAL CYCLE.
SO IT GIVES US REALLY GOOD
Alex says SO IT'S GOING TO HELP
YOU DETERMINE WHERE THE BEST
PLACES TO PUT A TURBINE
IN THE FUTURE?
Greg says YEAH, ABSOLUTELY, IT
HELPS WITH THAT, AMONG ALL THE
DIFFERENT DEVICES WE THAT WE USE
TO MEASURE FLOW,
THIS IS ONE OF THE CHEAPER ONES
THAT WE USE EARLY ON BUT IT'S
REALLY USEFUL THROUGHOUT THE
SITE ASSESSMENT PROCESS FOR
GIVING US A REALLY GOOD
UNDERSTANDING OF THE BIG
PICTURE OF WHAT THE FLOW IS
DOING THROUGH THE CHANNEL.
Alex says AND IS THERE A LOT OF
COULD THERE BE A LOT OF
Greg drops the surface drifters into the water and later picks up another one and points at the flow speed.
Greg says OH YEAH, ABSOLUTELY, I
MEAN WE'RE NOT TRYING TO
GENERATE ELECTRICITY TO POWER
HALIFAX OR ANYTHING LIKE THAT,
BUT TO POWER THESE COMMUNITIES,
SO IT'S REALLY ABOUT LOCAL
POWER PRODUCTION AND
LOCAL POWER USE.
THERE'S PROBABLY WAY MORE IN
THIS TIDAL CHANNEL HERE THAN THE
COMMUNITY COULD EVER USE,
SO WHAT WE REALLY THINK WE CAN
TAKE OUT AN AMOUNT TO MATCH
COMMUNITY USE SO IT'S
SUSTAINABLE AND IT
DOESN'T HAVE A BIG EFFECT ON THE
TIDAL CHANNEL ITSELF AND THE
MARINE LIFE THAT USES IT.
Tyler drops a driver into the water while Greg supervises. The drifter appears gently moving with the tide.
Alex says WITH TURBINE SITES
ALREADY BEING SELECTED AND MANY
TECHNICAL CHALLENGES BEING
OVERCOME, IT NOW APPEARS THAT
THE ONLY MAJOR OBSTACLES THAT
WILL LIMIT THE TOTAL NUMBER OF
ARE THE POTENTIAL ENVIRONMENTAL IMPACTS ON MARINE LIFE THAT FEED
AND MIGRATE IN THE BAY.
Doctor Graham Daborn is in his mid-sixties with a long white beard and white hair, and wears glasses. He is also wearing a blue shirt under a dark blue sweater.
A caption reads Doctor Graham Daborn. Professor Emeritus. Acadia University.
Graham says AT THE
PRESENT TIME I DON'T THINK WE
ARE IN A POSITION TO SAY WHAT
THAT LIMIT WOULD BE BECAUSE
WE KNOW SO LITTLE ABOUT THE
EFFECTS OF THESE INDIVIDUAL
TURBINES AND SIMILARLY THE
EFFECTS OF AN ARRAY OF THEM.
A fast clip shows a view of a lighthouse on the coast with seagulls circling, waves crashing on the cliffs, and Tyler and Alex in wetsuits carrying two canoes into the water.
SO THE STRATEGY IS WE WILL DO
IT INCREMENTALLY, PUT OUT THE
TURBINES, FIND THE ONES THAT
WILL WORK AND SURVIVE
IN THAT ENVIRONMENT AND ALL THE
TIME MONITORING WHAT
THE EFFECTS ARE SO THAT WE CAN
COME TO A POINT IN WHICH WE
SAY WE'RE APPROACHING A STAGE
IN WHICH THERE WILL BE NEGATIVE
EFFECTS AND THEREFORE THAT WOULD
BE THE TIME IN WHICH WE PUT
A CAP ON IT.
A clip shows a whale tail in the ocean, then Alex and Tyler canoeing through the bay.
Graham says WE DON'T WANT
TO TRADE OFF THE RICHNESS AND
THE ATTRACTIVENESS OF THE BAY OF
FUNDY FOR ENERGY.
IF WE CAN TAKE ENERGY OUT OF IT
CHANGING THE ECOSYSTEM OR
AFFECTING THE LIFE THAT'S IN
IT THEN THAT MAKES TIDAL POWER A
VERY ATTRACTIVE OPPORTUNITY.
Peter appears at the FloWave facility.
Peter says WE DON'T HAVE
THE LUXURY THAT WE HAD IN THE
PAST OF JUST USING ONE MAJOR
SOURCE JUST COAL OR JUST OIL
OR JUST GAS.
BECAUSE THEY ALL POLLUTE FOR
A START AND ALSO THEY ARE
RUNNING OUT IN SOME CASES.
SO IF WE ARE GOING TO USE
RENEWABLES, THEY ALL HAVE THEIR
PROS AND CONS, SO WE NEED TO
HAVE A MIX OF CLEAN
IT'S REALLY A MATTER OF HAVING
AS MANY WEAPONS IN OUR ARSENAL
AS WE CAN TO PRODUCE ENERGY.
Tyler and Alex sit on a rock at low tide in the bay.
Alex says MARINE RENEWABLE ENERGY IS
MORE THAN JUST A PIPE DREAM.
IT'S ALREADY HELPING SCOTLAND
MEET ITS TARGETS TO REDUCE
GREENHOUSE GAS EMISSIONS AND
NOW IT IS TIME FOR CANADA
AND THE REST OF THE WORLD TO
FOLLOW IN THEIR FOOTSTEPS.
Tyler says WHILE TIDAL AND WAVE
POWER WON'T BE ABLE TO SATISFY
OUR ENERGY DEMANDS ON THEIR
OWN THEY CAN DEFINITELY BE AN
IMPORTANT PART OF THE SOLUTION.
Alex says RENEWABLES MAY COST US A
LITTLE BIT MORE ON OUR
ELECTRICITY BILLS BUT IT'S NOT
NEARLY AS COSTLY AS THE
UNTOLD ECONOMIC PRICE OF CLIMATE
THAT'S ALREADY UPON US.
Tyler says THE BEST PART IS THAT THE
TECHNOLOGIES ALREADY EXIST.
WHAT WE NEED NOW IS AN INFORMED
AND EXCITED PUBLIC
TO HELP GOVERNMENT AND INDUSTRY
HARNESS THIS OCEAN OF ENERGY.
Alex says JOIN US AND DIVE DEEPER
INTO THE EPISODES AT
The End Credits roll.
