Hello and welcome. Today is the second semi-final of My Genius Idea,

0:00:160:00:20

the show that's looking for the biggest,

0:00:200:00:22

best and brightest ideas from all of you.

0:00:220:00:24

In My Genius Idea, we're looking for the next generation of inventors.

0:00:250:00:30

We received ideas from all over the UK.

0:00:320:00:35

Your genius ideas ranged from how to look after your pets,

0:00:350:00:38

robots to help around the home,

0:00:380:00:40

through to flying cars and eco-powered planes.

0:00:400:00:43

Only 18 ideas made it to the heats

0:00:430:00:46

and over six shows,

0:00:460:00:48

we picked our semi-finalists.

0:00:480:00:49

Last time, we found out who was the first finalist...

0:00:530:00:56

-Tybalt.

-..and now, we're looking for the second,

0:00:560:00:58

as three more inventors take their genius ideas

0:00:580:01:01

out into the real world to see if they can actually work.

0:01:010:01:05

In today's show, we'll be finding out

0:01:060:01:07

how well sound travels under water.

0:01:070:01:10

-Lots of crackling, that's it, really.

-We've set up mission control

0:01:100:01:14

at Europe's largest solar panel building.

0:01:140:01:16

It would make a big difference in space.

0:01:160:01:18

And we're at a pig farm, trying to keep our washing out of the mud.

0:01:180:01:22

And what we've definitely got here is mud today.

0:01:220:01:24

All our semi-finalists will have to impress expert inventor

0:01:240:01:27

and judge Tom Lawton,

0:01:270:01:28

and prove that their idea is worthy of a place in the Grand Final.

0:01:280:01:33

-Tom has always had a passion for inventing.

-I love it.

0:01:330:01:36

There are so many ideas all around us.

0:01:360:01:39

Under everybody's nose, there's a solution

0:01:390:01:41

that needs to be solved or a problem that hasn't been addressed yet.

0:01:410:01:44

Tom started inventing when he was ten, and by the time he was 21,

0:01:440:01:48

he developed his first product -

0:01:480:01:50

the world's first recordable alarm clock.

0:01:500:01:52

You always have ideas. Being an inventor is about

0:01:520:01:56

seeing those ideas through into something that's real.

0:01:560:01:59

He's gone on to build a successful career as an inventor,

0:01:590:02:03

winning international awards for his work.

0:02:030:02:06

Tom chose Tybalt and his

0:02:060:02:08

bike bleeper invention to become our first finalist.

0:02:080:02:11

What do you think is going to make the difference between

0:02:110:02:13

the young inventors that go home

0:02:130:02:15

and the young inventor that joins Tybalt in the final?

0:02:150:02:17

Well, they've all been on their real-world tests,

0:02:170:02:19

and it's all about learning from those real-world tests

0:02:190:02:22

about the problems you might face making your idea real.

0:02:220:02:25

I'm looking for them to have carried some of those ideas

0:02:250:02:27

-and discoveries forward.

-In these tests,

0:02:270:02:30

they'll each be reunited with their experts

0:02:300:02:33

to see if their invention can work out in the real world.

0:02:330:02:36

They'll have to report the results of their tests back to Tom.

0:02:360:02:39

He'll want to know how well the tests went and if the idea

0:02:390:02:42

can be improved, if they've any chance of winning a place

0:02:420:02:45

in the final.

0:02:450:02:46

Tom, you can relax for now. I'm about to introduce

0:02:460:02:50

our last three semi-finalists, but first,

0:02:500:02:51

let's remind ourselves how they got here.

0:02:510:02:53

Emily beat off the competition in Heat Five to secure

0:03:020:03:05

her place in the semi-final.

0:03:050:03:07

Her idea of a device to keep marine mammals

0:03:070:03:10

out of dangerous areas won Tom over.

0:03:100:03:13

-Emily.

-When I next pitch to Tom, I think he'll be looking for...

0:03:130:03:17

if I've improved my idea, if it's progressed.

0:03:170:03:22

Karampreet fought off tough competition in his heat

0:03:290:03:32

to win a place in today's semi. His idea

0:03:320:03:34

of putting solar panels in space

0:03:340:03:37

to beam power back to Earth impressed judge Tom.

0:03:370:03:40

When I was waiting for the result in front of Tom,

0:03:400:03:42

I was really nervous and, if I'm honest, probably not expecting

0:03:420:03:45

to get through, because the other two ideas were also genius.

0:03:450:03:48

Oliver won through in the first heat to win his place in the semi-finals.

0:03:560:04:00

His idea of a wireless controlled clothes line

0:04:000:04:04

gave him the edge with Tom.

0:04:040:04:06

I was really nervous when I was waiting to hear the results from Tom,

0:04:060:04:10

but I got there in the end,

0:04:100:04:12

so I was just over the moon when he said Oliver.

0:04:120:04:15

Our budding inventors all went out in the field

0:04:180:04:21

and developed their ideas further in real-world tests.

0:04:210:04:24

First up, Emily.

0:04:240:04:26

Her invention is a warning device

0:04:280:04:30

to keep sea mammals away from danger.

0:04:300:04:32

It works by playing warning sounds underwater

0:04:320:04:35

to keep them out of harm's way,

0:04:350:04:36

by using the sound of their most feared predator, a killer whale.

0:04:360:04:40

RECORDING OF WHALE

0:04:400:04:43

We're here on the stunning Isle of Mull off the west coast of Scotland,

0:04:450:04:49

a place rich in marine life and one of the best places in Europe

0:04:490:04:52

to see dolphins, seals and even whales.

0:04:520:04:55

We're going to be hooking up with Emily's expert, Jonathan Gordon,

0:04:550:04:59

on a research boat, to see how Emily's idea

0:04:590:05:01

might work in the real world.

0:05:010:05:03

Emily, what areas would you need to protect sea mammals from?

0:05:050:05:07

We need to protect them from military sea operations,

0:05:070:05:10

oil slicks and wind farm construction.

0:05:100:05:15

How does it feel to be in a part of the world that might actually

0:05:150:05:17

-use your idea?

-It feels really good. Before, it was just an idea,

0:05:170:05:21

but now, it's really coming to life and it's really exciting.

0:05:210:05:23

-Shall we go and meet your expert?

-Yeah.

-Come on.

0:05:230:05:26

-Morning.

-Hi, Jonathan.

0:05:270:05:28

-Good to see you again.

-Good to see you.

-Hi, Emily.

0:05:280:05:30

It's a big day for Emily. On board the research boat,

0:05:320:05:35

she's going to have the chance to see some of the sea mammals

0:05:350:05:37

her idea could help protect,

0:05:370:05:39

and then test some of the technology needed to make it work.

0:05:390:05:42

Emily, we're heading out there to an island called Calve Island.

0:05:420:05:46

It's one of the places that seals come and haul-out, to rest.

0:05:460:05:49

She'll have to report all of the results from her test back to Tom,

0:05:500:05:54

as she tries to win the last spot in the final.

0:05:540:05:56

That's so cool, look at that seal just there.

0:06:000:06:02

I think it's really amazing, because I always just thought

0:06:040:06:09

they were an extraordinary and beautiful animal.

0:06:090:06:11

Seeing them up close, I feel they're even more beautiful.

0:06:110:06:13

-It's nice to get so close, isn't it?

-Yeah, it's amazing.

0:06:130:06:16

Having seen the type of sea life

0:06:160:06:18

that could benefit from Emily's idea,

0:06:180:06:20

Jonathan now wants to show her how well sound can travel underwater.

0:06:200:06:24

Emily, this is called a hydrophone.

0:06:240:06:27

It's really like a microphone that you can put in the water,

0:06:270:06:30

and we can listen and see what we can hear.

0:06:300:06:31

Does the sound travel well under the water?

0:06:310:06:34

Extremely well, better than it travels through the air.

0:06:340:06:37

A lot of animals that live in the sea,

0:06:370:06:38

but particularly marine mammals, are very acoustically oriented.

0:06:380:06:42

That's their main sense for detecting all sorts of things,

0:06:420:06:45

including things they need to be frightened of.

0:06:450:06:47

Emily, have a listen, see what you can hear.

0:06:470:06:50

CRACKLING

0:06:530:06:57

Lots of crackling, that's it, really.

0:06:570:06:58

Yeah. What that crackling is

0:06:580:07:00

are little shrimps that live on the bottom and make very loud clicking,

0:07:000:07:05

cracking noises. That's often what you hear

0:07:050:07:08

when you're in a rocky environment, crackling.

0:07:080:07:11

Emily now knows that sound travels really well underwater,

0:07:130:07:16

but just how far away can it be heard?

0:07:160:07:19

To find this out, Jonathan's put together a test.

0:07:190:07:22

He's going to be playing the sound of the killer whale

0:07:220:07:24

-from the lifeboat...

-This is our underwater speaker.

0:07:240:07:27

Do you want to lower it gently into the water?

0:07:270:07:30

..and then, they'll head back out into the harbour,

0:07:310:07:34

to see how far the sound travels.

0:07:340:07:35

-How far away are we now?

-650 metres.

0:07:350:07:41

That would be a really useful distance to be able to keep animals

0:07:410:07:44

away from dangerous things, and give them protection.

0:07:440:07:47

This test is key in getting their idea to work.

0:07:470:07:50

At 650 metres, could a sea mammal about to swim into danger

0:07:500:07:53

hear the warning sound and turn away?

0:07:530:07:56

To find out, they drop the listening device into the water...and wait.

0:07:560:08:01

WAILING

0:08:010:08:03

-You can hear that.

-Wow. Even I can hear that.

0:08:030:08:05

For the sea mammals, that would be a really useful distance,

0:08:050:08:07

to be able to protect them.

0:08:070:08:08

At nearly three-quarters of a kilometre away,

0:08:080:08:11

the whale sound can be heard loud and clear.

0:08:110:08:13

-It's a great result.

-I think it's really amazing

0:08:130:08:16

that we can hear from here so clearly.

0:08:160:08:18

Yeah, I'm surprised myself that it's working so well.

0:08:180:08:21

I think the next step now would be to try and

0:08:210:08:24

do some experiments with real animals in the wild.

0:08:240:08:27

So, Emily, how did you find your day out at sea?

0:08:300:08:33

I found it really exciting, because it was...

0:08:330:08:35

really up close to the animals. It really made me feel for them

0:08:350:08:39

and realise how important it actually is to me to save them.

0:08:390:08:43

So, a great day for Emily.

0:08:450:08:47

If she could develop her idea further, she might make an important

0:08:470:08:50

contribution towards conserving sea mammals in the future.

0:08:500:08:54

Next to put their idea to the test in the real world is Karampreet.

0:08:540:08:58

Karampreet wants to invent the next generation of renewable energy

0:08:590:09:03

by launching a satellite into space, to capture the powerful rays

0:09:030:09:06

of the sun, and then beam this super solar energy back to Earth.

0:09:060:09:10

Glyndwr University are leaders in solar energy research

0:09:100:09:14

and technology. They're housed in a building that has

0:09:140:09:17

the largest solar panel of its kind in the whole of Europe.

0:09:170:09:20

This wall produces 85 kilowatts of power,

0:09:200:09:24

enough to power 15 houses for a year.

0:09:240:09:26

So this is the perfect place to test Karampreet's invention.

0:09:260:09:30

Karampreet, talk to us about who's going to benefit from this.

0:09:310:09:34

I think there's already areas where they don't have enough energy,

0:09:340:09:37

but I think even more developed countries like the UK,

0:09:370:09:39

in a few years, we could face an energy crisis. So I think it would be

0:09:390:09:43

-helpful all over the world.

-I think it's time to meet Dr Douglas,

0:09:430:09:46

-your expert, shall we?

-Let's go.

0:09:460:09:49

Dr Douglas Halliday has brought along the solar panel

0:09:510:09:54

that could make Karampreet's invention work,

0:09:540:09:56

and possibly win him that place in the final.

0:09:560:09:59

The first part of the real-world test

0:09:590:10:01

is to show why putting solar panels in space

0:10:010:10:03

is more efficient than using them here on planet Earth.

0:10:030:10:06

In space, you're not limited by climatic radiations and cloud cover.

0:10:060:10:11

Down here, we've got some artificial cloud.

0:10:110:10:14

The idea is, we're going to cover our panel with pretend cloud

0:10:140:10:18

and look at the impact on the power that's being produced.

0:10:180:10:21

The voltmeter reading is around 32 vaults.

0:10:210:10:24

What happens when we put on our fake cloud?

0:10:240:10:26

Karampreet, if you'd like to go

0:10:260:10:28

and look at the voltmeter and tell us what the meeting is.

0:10:280:10:31

-It's around 28 volts.

-OK, so we've had a drop in the voltage output

0:10:310:10:36

of over four volts from this panel,

0:10:360:10:38

which would obviously reduce the amount of power it produces.

0:10:380:10:41

One of the key benefits of installing this panel in space

0:10:410:10:44

is that it's not limited in this way.

0:10:440:10:47

I'm really encouraged by this, and it does show that it would make

0:10:470:10:49

-a big difference is space, making it worthwhile.

-What a great start.

0:10:490:10:52

Yeah, I'm really happy with this.

0:10:520:10:54

So, we've shown how much more solar energy can be collected

0:10:560:10:59

without the problem of cloud cover. Now, we've got to think about

0:10:590:11:01

how that solar energy collected up in space can be transmitted

0:11:010:11:05

back here on Earth, to be used as an alternative energy source.

0:11:050:11:08

You need to transmit the energy from the solar panel back down to Earth.

0:11:090:11:13

One of the ways you can think about doing that is with microwaves.

0:11:130:11:17

Dr Halliday has set up a demonstration to show how the energy

0:11:170:11:21

from space could be transferred to Earth using microwave beams.

0:11:210:11:25

On the left, we have space, which will transmit the microwaves

0:11:250:11:28

to the antenna on the right, planet Earth.

0:11:280:11:31

The amount of power received is displayed on this meter.

0:11:310:11:34

Right, there's another problem and challenge we have to overcome.

0:11:340:11:37

If you sit down between the two antenna, we can demonstrate here.

0:11:370:11:42

What you'll notice is that the power level has dropped, almost to zero.

0:11:420:11:47

That indicates the issues that happen

0:11:470:11:50

-when the signal is interrupted.

-What kind of interruptions

0:11:500:11:52

would we get when we transmit this microwave beam back to Earth?

0:11:520:11:55

First of all, there's cloud cover, such as we have today.

0:11:550:11:58

There's also the possibility of aircraft,

0:11:580:12:01

or even migrating birds that may get in the way of the microwave beam.

0:12:010:12:06

One of the other issues is that the solar satellite

0:12:060:12:09

will be 25,000 miles away from Earth.

0:12:090:12:12

In order to demonstrate the difficulties of transmitting

0:12:120:12:14

over a large distance, Karampreet, if you could pick up the antenna

0:12:140:12:18

and just walk down there with it.

0:12:180:12:19

You can see that as he's walking away,

0:12:190:12:22

the signal is dropping almost to zero, because of the extra distance

0:12:220:12:25

involved between the antenna.

0:12:250:12:27

A major stumbling block, where do we go from here?

0:12:270:12:30

One stage going forward would be to think about using a satellite dish,

0:12:300:12:35

which would focus and direct the energy in a specific direction.

0:12:350:12:39

But that wouldn't necessarily overcome the distance that

0:12:390:12:42

we've been talking about - 25,000 miles

0:12:420:12:45

from the solar panels to the Earth.

0:12:450:12:47

I'm feeling confident that we can overcome this.

0:12:470:12:49

Karampreet may still be confident,

0:12:490:12:51

but if he's any chance of making it to the final,

0:12:510:12:53

he'll have to think of a better way to transmit the energy

0:12:530:12:55

before he reports back to Tom.

0:12:550:12:57

It is a bit disheartening that there are new issues to overcome,

0:12:570:13:00

but as an inventor, you have to keep going and keep trying.

0:13:000:13:03

I think one of the important things is never to lose hope.

0:13:030:13:06

Karampreet's got a great idea on his hands, but it's an ambitious one.

0:13:060:13:10

There are problems with transmitting all that energy

0:13:100:13:13

from the solar panel 25,000 miles away to here on Earth. Next up,

0:13:130:13:17

I'm off to hang out with Oliver.

0:13:170:13:19

Oliver's invention was inspired by his mum, who doesn't like walking on

0:13:200:13:23

their muddy garden to hang out the washing.

0:13:230:13:26

The line moves around, which means users don't have to step in mud.

0:13:260:13:29

It also comes with an alarm to tell you when it's dry.

0:13:290:13:32

To test Oliver's washing line out, I've roped in some extras

0:13:330:13:37

who love really muddy places. We're here at a pig farm to see if

0:13:370:13:40

we can hang out the washing without treading in the mud.

0:13:400:13:43

Come on then, girls, ready for your close-up.

0:13:430:13:45

So, Oliver, we're here with your family at a pig farm.

0:13:480:13:51

-Are you as messy as these guys at home?

-Probably.

0:13:510:13:55

-Is he, Mum?

-Yes, he definitely is.

-So I guess you're hoping that

0:13:550:13:59

-Oliver's invention comes to reality?

-Yes, I definitely am,

0:13:590:14:02

because I hate going out with muddy feet

0:14:020:14:04

in my garden to hang my washing out.

0:14:040:14:06

Let's see if we can solve this problem.

0:14:060:14:08

It's time to meet your expert. Come on, let's go.

0:14:080:14:10

Oliver's expert, Lee Russell, has built a prototype of his invention.

0:14:130:14:17

-Right, Lee, what have we got here?

-Oliver wanted his washing line

0:14:170:14:20

to be able to move along so his mum didn't have to get in the mud.

0:14:200:14:23

That's one of the first things we're going to show.

0:14:230:14:25

What we've definitely got here is mud today. We're going to try

0:14:250:14:28

to keep out of that as much as we can. After that,

0:14:280:14:30

we're going to test to see if we can tell when the washing's dry.

0:14:300:14:33

We're ready for the first part of the test, Oliver.

0:14:330:14:36

What do you want me to do?

0:14:360:14:38

First of all, I'd like you to hang out the washing.

0:14:380:14:42

No worries, Oliver.

0:14:420:14:43

I do this all the time at home.

0:14:430:14:45

Right, OK. That's on there. OK, Oliver. Three, two, one...

0:14:480:14:54

Press the button!

0:14:540:14:55

-Yes!

-Yes!

0:14:560:14:58

-You've done it.

-Yay!

-'So, the first part of the test

0:14:580:15:01

'was a massive success for Oliver, but now, they've got to see whether

0:15:010:15:04

'that line can send a signal to Oliver's mum

0:15:040:15:07

'and let her know when the clothes are dry,

0:15:070:15:08

'meaning Oliver could breeze into that final spot.'

0:15:080:15:12

Right, Lee, how are we going to work the second part of the test?

0:15:120:15:15

We've got this little system here.

0:15:150:15:16

It's kind of like a mobile phone.

0:15:160:15:18

It will receive a signal from the unit on the washing line,

0:15:180:15:21

and when the washing's dry, it will receive a little message saying

0:15:210:15:25

-"washing dry" and that buzzer will go off.

-Right, I'll hang this up.

0:15:250:15:28

The science behind the alarm system

0:15:280:15:31

is to measure the wet clothes over a period of time.

0:15:310:15:34

As clothes dry, the water in them evaporates and they become lighter.

0:15:340:15:37

So, once the weight stops changing, the washing should be dry.

0:15:370:15:41

For our real-world test, we're using dry clothes to check the alarm

0:15:410:15:45

so, if it works, it should go off more or less straightaway

0:15:450:15:47

once we've hung the clothes out. It's all riding on this.

0:15:470:15:51

In theory, when I plug this receiver in,

0:15:510:15:54

it should send a message to Oliver and his mum.

0:15:540:15:57

So, let's join them now.

0:15:570:15:59

Oliver, I'll let you do the honours.

0:16:010:16:03

Plug the battery in.

0:16:030:16:05

We're hoping we get a message that says...the washing is done.

0:16:050:16:08

Lee's system weighs the washing every five minutes

0:16:080:16:12

and then decides whether to send a signal.

0:16:120:16:15

So, we waited...

0:16:150:16:16

..and waited...

0:16:170:16:19

PIG GRUNTS

0:16:190:16:21

..and, just as we were about to give up...

0:16:210:16:23

-BUZZING

-Yes!

-Yes!

0:16:230:16:28

Washing dry!

0:16:290:16:30

Oliver, what a success! Both parts of the test worked today.

0:16:320:16:35

I'm feeling really great. It's just a brilliant day,

0:16:350:16:41

and I hope to get through to the final with this idea.

0:16:410:16:44

Although it's been a success,

0:16:440:16:46

expert Lee has spotted a problem - the wind.

0:16:460:16:49

When the wind blows, the clothes will tug on the line and could give

0:16:490:16:52

a false reading to the sensor, showing they're changing weight.

0:16:520:16:55

So, Oliver, how did you find your day at the pig farm?

0:16:570:17:00

It was really good.

0:17:000:17:02

I loved learning about my idea and how I could venture forward from it.

0:17:020:17:07

-You've got lots to think about, haven't you?

-Yep.

0:17:070:17:09

-But overall, happy? Thumbs up?

-Yeah.

-Yes!

0:17:090:17:13

We've seen how Oliver's idea might actually work, although they didn't

0:17:130:17:16

take into account the elements - how will the wind affect his line?

0:17:160:17:19

Overall though, the skies look blue for Oliver and his genius idea.

0:17:190:17:24

With the real-world tests completed, they've each thrown up

0:17:250:17:28

different results for the young inventors. Emily's been able

0:17:280:17:31

to test the technology that will make her idea work.

0:17:310:17:34

Karampreet has to solve the difficult problem of transferring

0:17:340:17:38

the energy back to Earth. And Oliver's seen his line work,

0:17:380:17:42

but needs to ensure the weighing mechanism -

0:17:420:17:44

to tell when the clothes are dry - remains accurate when it's windy.

0:17:440:17:47

But who can impress Tom the most with their overall results

0:17:470:17:51

and win themselves that place in the final?

0:17:510:17:53

So, Tom, we've just seen the real tests there.

0:17:550:17:57

Anything that caught your eye?

0:17:570:17:59

Yeah, it's all great.

0:17:590:18:01

In particular, it's good to see even Karampreet perhaps becoming aware of

0:18:010:18:05

how big his idea is and some of the hurdles

0:18:050:18:08

he's going to face in making it a reality.

0:18:080:18:10

So, yeah, that's the point of the real-world tests -

0:18:100:18:12

to discover things that you couldn't do in theory.

0:18:120:18:15

Is it exciting for you to see these ideas

0:18:150:18:17

kind of start to become more real?

0:18:170:18:20

It is. I'm not even the one who's developing them.

0:18:200:18:22

So, yeah, it's great to be sat back and seeing what they're developing.

0:18:220:18:26

-Really good.

-I know we've got three very excited and pretty nervous

0:18:260:18:29

young inventors waiting to chat with you and talk you through

0:18:290:18:32

-their ideas. I'll leave you to make some final preparations.

-Thanks.

0:18:320:18:36

OK. You know what time it is, don't you? It's time to speak to Tom...

0:18:360:18:42

'All three of our budding inventors

0:18:420:18:44

'now have to pitch to Tom for a place in the final.

0:18:440:18:46

'First up, it's...'

0:18:460:18:48

-Oliver. Are you ready?

-Yeah.

-Are you prepared?

-Yeah.

0:18:480:18:51

Bring it on. Off you go. Good luck!

0:18:510:18:53

To impress Tom, Oliver will need to remember all the technology

0:18:530:18:56

behind his idea, as well as proving that his invention

0:18:560:18:58

still has the potential to work. Will Tom be convinced

0:18:580:19:02

that he should win a place in the final?

0:19:020:19:03

Hi, Oliver, lovely to see you. I understand you've been testing

0:19:030:19:07

your wireless washing-line on a farm with some pigs. How did it go?

0:19:070:19:12

-It went really well.

-In particular, what aspects went well?

0:19:120:19:16

-The washing line went forwards and backwards...

-Yes.

0:19:160:19:19

..first time, so that was really good.

0:19:190:19:21

And the alarm went off at the right time, and when it went off,

0:19:210:19:28

we all jumped and cheered, so it was really good.

0:19:280:19:31

Did any problems arise during this test?

0:19:310:19:34

We thought about the problems and I've got two.

0:19:340:19:39

The pulley system must allow pegs to go round it.

0:19:390:19:43

If the pegs can't go around the pulley system,

0:19:430:19:46

-it's just going to go forwards and backwards.

-Right, OK.

0:19:460:19:49

And then you're not going to be able to get the far clothing to you, etc.

0:19:490:19:53

You mentioned that you had two problems. What was the other?

0:19:530:19:56

The sensor must go off at the right time.

0:19:560:20:00

Lee, my expert, says that the sensor must be adapted, so the wind

0:20:000:20:05

-doesn't interfere, so it sends the alarm just at the right time.

-OK.

0:20:050:20:10

It pulls the weight of the clothes down and makes them appear heavier?

0:20:100:20:14

-Yeah.

-Listen, thank you very much for answering all my questions

0:20:140:20:18

and for another presentation.

0:20:180:20:20

I think you've done really well. You seem to have learned a lot

0:20:200:20:23

and seem to relish the challenge of overcoming another problem and...

0:20:230:20:28

-well done.

-Thank you.

-Thank you, Oliver.

0:20:280:20:30

I think it went really well today.

0:20:310:20:33

It's all dependent on what he decides.

0:20:330:20:37

Next up, it's Karampreet. Has he come up with a solution

0:20:390:20:42

to transfer the power from his solar space panels back to Earth

0:20:420:20:46

that will persuade Tom he's worthy of a place in the final?

0:20:460:20:49

Hi, Karampreet. It's great to see you again.

0:20:490:20:51

I understand you've been researching your solar space panels

0:20:510:20:56

further by visiting the largest solar wall in Europe.

0:20:560:20:59

-How did that go?

-That went really well.

0:20:590:21:01

I made a few slight modifications to my idea whilst I was there.

0:21:010:21:05

OK. Interesting, I look forward to learning about that.

0:21:050:21:08

What aspects of the test that you went through worked well?

0:21:080:21:10

In the first experiment, we allowed a 3 square metre solar panel

0:21:100:21:14

to collect solar energy on what was a rather cloudy day.

0:21:140:21:17

-The energy output we got was 33 Volts.

-OK.

0:21:170:21:21

We then obstructed some of the light coming in with an artificial cloud,

0:21:210:21:24

-and the new reading came in at 27 Volts.

-OK.

0:21:240:21:27

-That's a reduction of around 20%.

-So it's very clear

0:21:270:21:31

that cloud cover affects the amount of solar energy you can collect.

0:21:310:21:35

It does. Even on a sunny day, the atmosphere

0:21:350:21:39

absorbs around 40% of the solar energy we'd otherwise receive.

0:21:390:21:42

-Which is a huge amount.

-And we're obviously limited to daytime hours.

0:21:420:21:45

And these issues would be overcome by my idea.

0:21:450:21:48

So these were things you discovered and you defined.

0:21:480:21:50

Were there any problems that arose during your test?

0:21:500:21:54

In a second experiment,

0:21:540:21:55

we transmitted microwave energy through the air

0:21:550:21:58

and allowed some of it to be collected by a receiver antenna.

0:21:580:22:00

-OK.

-The reading we got was actually extremely small

0:22:000:22:03

and was next to nothing if something obstructed the path.

0:22:030:22:06

-OK.

-Or if we increased the distance

0:22:060:22:08

from the transmitter to the receiver antenna.

0:22:080:22:10

-OK.

-And this showed it would be imperative to send the microwave

0:22:100:22:13

energy as a focused beam, so all the energy is collected by a dish.

0:22:130:22:17

I certainly credit you for thinking so big with the whole of this idea.

0:22:170:22:20

A great presentation again. You've answered all my questions.

0:22:200:22:23

You, of course, have researched this thoroughly,

0:22:230:22:25

-so, thank you very much, Karampreet.

-Thank you.

0:22:250:22:27

I thought my pitch went very well.

0:22:290:22:31

I did my pitch as best I could. If I don't get through,

0:22:310:22:34

I won't be worried, because there's nothing else I could have done.

0:22:340:22:38

Finally, it's Emily's turn to pitch her marine mammal protection system.

0:22:390:22:44

Tom will be judging all the young inventors on how well

0:22:440:22:46

their ideas have progressed from the heats,

0:22:460:22:48

and the results from the real-world tests.

0:22:480:22:51

-Hi, Emily, it's a pleasure to see you again.

-Hi.

0:22:510:22:54

I hear that you got to see some marine mammals up close

0:22:540:22:58

in the real world as part of your reward tests.

0:22:580:23:00

Yeah, it was really cool. We saw two seals and they were really pretty.

0:23:000:23:03

How did the tests go?

0:23:030:23:05

The tests went really well.

0:23:050:23:06

Because we were quite far away and the sound travelled so well through

0:23:060:23:11

-the water, it was really good that we could still hear it.

-Yeah.

0:23:110:23:14

It actually travels better than it does through the air.

0:23:140:23:16

-OK.

-It was really quite amazing.

-Do you think if there were other

0:23:160:23:20

ambient sounds that were going on - maybe lots of fishing,

0:23:200:23:23

lots of boat activity -

0:23:230:23:24

do you think that might affect the clarity of the sound you heard?

0:23:240:23:28

When we were playing my sound, we could still hear all the boats,

0:23:280:23:33

but you can still make out which sound it was

0:23:330:23:35

and really clearly, so I don't think it would affect it at all.

0:23:350:23:37

So, over and above the sound of the other boats,

0:23:370:23:39

you could still hear the sound clearly?

0:23:390:23:41

The sound you played through the hydrophone,

0:23:410:23:43

was that an actual sample from a killer whale?

0:23:430:23:47

Yeah. Jonathan said he'd recorded it a while back

0:23:470:23:50

-and they were the real sounds.

-OK, OK.

0:23:500:23:52

So, it's an accurate reproduction of a recording of that sound,

0:23:520:23:56

and that's what's played through the hydrophone.

0:23:560:23:58

What have you identified is the primary...

0:23:580:24:02

locations where this technology would be of greatest benefit?

0:24:020:24:06

I was speaking with Jonathan.

0:24:060:24:08

We realised...

0:24:080:24:10

-that wind turbine construction is a major threat to them.

-Yeah.

0:24:100:24:14

It's a really big part of noise pollution.

0:24:140:24:17

There's always people on patrol boats looking out for the animals.

0:24:170:24:22

If they're spotted, the operation is immediately stopped

0:24:220:24:26

and it can't continue until all the animals are away.

0:24:260:24:28

-OK.

-If we could keep them away before they got near,

0:24:280:24:32

-it would save the company time and money.

-Yes, OK.

0:24:320:24:35

-Listen, well done, and thank you for a clear presentation.

-Thank you.

0:24:350:24:39

I thought it went really well. I'm really happy

0:24:420:24:45

with what I said to Tom today and I hope he puts me through to the final.

0:24:450:24:49

Oliver, Karampreet and Emily have tested

0:24:510:24:55

their ideas in the real world and have pitched their results to Tom.

0:24:550:24:59

Only one of them can win the last place in the all-important final.

0:24:590:25:03

Will it be Oliver and his idea for

0:25:030:25:06

a wireless controlled washing line?

0:25:060:25:08

Karampreet's solar panels in space?

0:25:080:25:12

Or Emily's marine mammal

0:25:120:25:13

protection system?

0:25:130:25:15

Tom, it's the second semi-final and these decisions

0:25:150:25:18

-don't get any easier, do they?

-No, they don't.

0:25:180:25:20

-This has been the toughest decision I've had to make so far.

-Really?

0:25:200:25:23

Really difficult. Weighing everything up,

0:25:230:25:25

-it's been really challenging.

-OK. It may have been challenging,

0:25:250:25:29

but have you come to a final decision?

0:25:290:25:31

-Have you decided who is going to be in the final?

-I have, yes.

0:25:310:25:35

OK, Thomas, if you'd like to take a seat,

0:25:350:25:36

I'll welcome in our young inventors.

0:25:360:25:39

It's crunch time.

0:25:390:25:41

They've all spent time testing their ideas and have pitched them to Tom.

0:25:410:25:45

But who has won that place in the final?

0:25:450:25:48

How are you all feeling?

0:25:500:25:51

-Nervous.

-There's a lot of tension in the room.

0:25:510:25:54

You've all done so well to get this far - to the semi-final.

0:25:540:25:57

Tom has admitted this has been

0:25:570:25:58

the most difficult decision he's had to make yet.

0:25:580:26:01

Nevertheless, he has come to a decision.

0:26:010:26:04

-So, Tom, it's over to you.

-Yeah, the three of you

0:26:040:26:08

have done brilliantly, to echo what Johnny said.

0:26:080:26:11

Oliver, you've shown a true inventive spirit

0:26:110:26:13

and you constantly find solutions to all the problems you encounter,

0:26:130:26:17

but I do still question whether this is the best solution

0:26:170:26:20

to the problem of drying clothes.

0:26:200:26:23

Karampreet, your capacity to think big is utterly inspiring.

0:26:230:26:27

So too is your ability to underpin your ideas

0:26:270:26:30

with intelligent thinking and hard facts. However, I still wonder if

0:26:300:26:34

there are too many unknown factors that make this idea

0:26:340:26:37

a fantastic area for further research.

0:26:370:26:41

Emily, it's a unique idea and a very clever one too.

0:26:410:26:45

But while your expert believes it will work,

0:26:450:26:48

we still haven't seen it work in the wild.

0:26:480:26:51

All things considered, I have come to a conclusion and...

0:26:510:26:54

the young inventor that I'm going to send through to the final is...

0:26:540:26:59

..Emily.

0:27:060:27:08

So, Emily wins the last place in the final with her idea of

0:27:080:27:12

a marine mammal protection system,

0:27:120:27:14

and will go head-to-head with Tybalt and his bike bleeper.

0:27:140:27:17

Emily, did you think you were going to make it through?

0:27:170:27:20

I thought I'd have a chance of getting through, but because

0:27:200:27:24

-both the boys' ideas were really good, I wasn't sure.

-Well done,

0:27:240:27:28

you got through to the final!

0:27:280:27:30

So, we have our second and last genius idea through to the final,

0:27:300:27:33

and it was Emily's. Over these eight shows,

0:27:330:27:36
