0:00:16 > 0:00:18Hi and welcome to My Genius Idea,
0:00:18 > 0:00:21the show that's looking for the biggest, best and brightest
0:00:21 > 0:00:23ideas from all of you.
0:00:25 > 0:00:28In My Genius Idea, we're looking for the next generation of inventors.
0:00:31 > 0:00:33We received ideas from all over the UK.
0:00:33 > 0:00:37Genius ideas ranged from how to look after your pets,
0:00:37 > 0:00:39robots to help around the home,
0:00:39 > 0:00:42through to flying cars and eco-powered planes.
0:00:42 > 0:00:45Only 18 ideas made it to the heats.
0:00:48 > 0:00:50They'll go head-to-head to see who'll be crowned
0:00:50 > 0:00:52the overall winner.
0:00:52 > 0:00:54Our budding inventors will work with experts
0:00:54 > 0:00:57to help their inventions come to life.
0:00:57 > 0:01:00They'll go behind the scenes of some of the UK's most successful
0:01:00 > 0:01:03organisations to give them the inspiration needed
0:01:03 > 0:01:06- to progress their inventions further.- I used it to inspire me.
0:01:06 > 0:01:09Deciding if they can progress in the competition
0:01:09 > 0:01:13will be down to expert inventor and judge Tom Lawton.
0:01:17 > 0:01:19Tom has always had a passion for inventing.
0:01:19 > 0:01:21I love it! There are so many ideas all around us.
0:01:21 > 0:01:24Under everybody's nose, there's a solution
0:01:24 > 0:01:26or a problem that hasn't been addressed yet.
0:01:26 > 0:01:29Tom started inventing when he was 10.
0:01:29 > 0:01:33By the time he was 21, he developed his first product,
0:01:33 > 0:01:35the world's first recordable alarm clock.
0:01:35 > 0:01:37You always have ideas.
0:01:37 > 0:01:41And being an inventor is about seeing those ideas through
0:01:41 > 0:01:44- into something that's real.- He's gone on to build a successful career
0:01:44 > 0:01:47as an inventor, winning international awards for his work.
0:01:47 > 0:01:50It's great doing a programme about young inventors
0:01:50 > 0:01:54because they have a very fresh perception of the world.
0:01:54 > 0:01:56I hope to be inspired by some of these young minds.
0:01:57 > 0:02:00Hoping to impress Tom with their ideas today are:
0:02:08 > 0:02:11And here they are, our three young inventors.
0:02:11 > 0:02:15Welcome, guys, to the Nerve Centre. How are you all feeling? Nervous?
0:02:15 > 0:02:17- Yeah.- A little bit, yeah.
0:02:17 > 0:02:20I can feel the tension in the air. OK, I'm coming to you, Georgia.
0:02:21 > 0:02:23What's the big idea?
0:02:23 > 0:02:25Well, my idea is a bike
0:02:25 > 0:02:29with airbags so if you fall off, you won't hurt yourself.
0:02:29 > 0:02:32Cycling fan Georgia hopes to clean up in today's show.
0:02:32 > 0:02:35Using her own experience of falling off her bike,
0:02:35 > 0:02:40she's come up with her own genius idea - airbags for bikes.
0:02:40 > 0:02:43I was out riding with my friends on my bike
0:02:43 > 0:02:45and I fell over
0:02:45 > 0:02:47and that's how I thought of my idea.
0:02:47 > 0:02:50I think I have the best idea because it can help people.
0:02:50 > 0:02:53Brilliant. What a righteous cause! Great stuff.
0:02:53 > 0:02:54Tybalt, I'm coming to you next.
0:02:54 > 0:02:58I've invented a bike bleeper
0:02:58 > 0:03:01which warns car drivers when there's a cyclist ahead.
0:03:01 > 0:03:05Mountain biker Tybalt has come up with the revolutionary idea
0:03:05 > 0:03:09to make the road safer for both cyclists and motorists.
0:03:09 > 0:03:11I designed the bike bleeper
0:03:11 > 0:03:14to try and stop people getting hit on their bikes.
0:03:15 > 0:03:18Everyone who drives and who bikes should own one.
0:03:20 > 0:03:22Catherine, fill us in.
0:03:22 > 0:03:25I designed a voice activated door.
0:03:25 > 0:03:29A voice activated door? That sounds impressive. I'd like to have one.
0:03:30 > 0:03:34Keen swimmer Catherine wants the freedom to move between rooms
0:03:34 > 0:03:36without having the hassle of turning the handle
0:03:36 > 0:03:38by using speech technology.
0:03:38 > 0:03:41My idea is a door
0:03:41 > 0:03:43and you say, like, "Open"
0:03:43 > 0:03:44and then it will open.
0:03:44 > 0:03:47It's useful for people who are carrying things.
0:03:49 > 0:03:52I think my idea is special because it's quite good
0:03:52 > 0:03:55for people like me who have brothers or sisters
0:03:55 > 0:03:57and they don't want them in their room!
0:03:57 > 0:04:00In the My Genius Idea HQ,
0:04:00 > 0:04:02Georgia, Tybalt and Catherine
0:04:02 > 0:04:06will each have one hour to develop their idea with a top specialist.
0:04:06 > 0:04:10Georgia's working on airbags for bikes with Stewart Humby,
0:04:10 > 0:04:12an accident investigator.
0:04:12 > 0:04:15You've got this fabulous idea for putting an airbag onto a bike.
0:04:15 > 0:04:18- Yeah.- What can you tell me about it so far?
0:04:18 > 0:04:19What have you thought about?
0:04:19 > 0:04:22Like, if you're on your bike and you fall off,
0:04:22 > 0:04:26if it tilts too far to the side like it's going to fall or crash,
0:04:26 > 0:04:29- the airbags will come out and you'll land on them.- Fantastic.
0:04:30 > 0:04:33Have you thought about where you want to the put the airbags?
0:04:33 > 0:04:36In the handlebars and on the seat.
0:04:36 > 0:04:40OK. Have you thought about putting them on the occupant as well
0:04:40 > 0:04:42as on the bike, or only on the occupant or the bike?
0:04:42 > 0:04:45Yeah, like, on the bike as well as on...
0:04:45 > 0:04:49You could have a jacket with a bag in the pockets.
0:04:49 > 0:04:52The other thing to think about is around your neck as well.
0:04:52 > 0:04:55Often, when you fall off and hit your head, it twists it.
0:04:55 > 0:04:57Like a hoodie and you can have it in the side.
0:04:57 > 0:05:01Fantastic, yeah! A hoodie airbag, brilliant idea.
0:05:01 > 0:05:03With Georgia exploding with ideas,
0:05:03 > 0:05:07Catherine is getting to work on her invention with Peter Bell,
0:05:07 > 0:05:08a speech recognition expert.
0:05:08 > 0:05:12Where would you have your door? What sort of door would it be?
0:05:12 > 0:05:16- It'd be like a house door.- Right. A door in a normal family home?
0:05:16 > 0:05:20- Yeah.- What would be the advantage of having it voice activated?
0:05:20 > 0:05:23You wouldn't need a key so you wouldn't lose it.
0:05:23 > 0:05:26- So you wouldn't lose the key. You'd always be able to get in.- Yeah.
0:05:26 > 0:05:30I assume it'll be important that this door only let through
0:05:30 > 0:05:33- the right kind of people? - Yeah.- Is that right?
0:05:33 > 0:05:35How do you think that might work?
0:05:35 > 0:05:37It would only recognise your voice
0:05:37 > 0:05:39so you programme it to recognise just your voice.
0:05:39 > 0:05:43We have two types of technology that we tend to use
0:05:43 > 0:05:45for these kind of applications.
0:05:45 > 0:05:47We never thought about doing it with a door.
0:05:47 > 0:05:51But one method is to recognise the words that people are saying
0:05:51 > 0:05:52and then the other method
0:05:52 > 0:05:55is to try and recognise individual speakers.
0:05:55 > 0:05:59We call one speech recognition and the other one speaker recognition,
0:05:59 > 0:06:03- or sometimes speaker identification. - So, good news for Catherine -
0:06:03 > 0:06:06the technology exists to make her idea work.
0:06:06 > 0:06:09Meanwhile, Tybalt is with Chris Styles,
0:06:09 > 0:06:12finding out what technology is available for his invention.
0:06:12 > 0:06:16You've come here with an awesome idea. Can you tell me more about it?
0:06:16 > 0:06:19I've invented a bike bleeper to save the lives of cyclists
0:06:19 > 0:06:21on the road.
0:06:21 > 0:06:26If there's a device what could maybe warn the car driver
0:06:26 > 0:06:30if there was a cyclist ahead round the bend. I thought to myself...
0:06:30 > 0:06:32"What can travel round a bend
0:06:32 > 0:06:35"by some sort of signal?"
0:06:35 > 0:06:38So I used a radio transmitter and radio receiver -
0:06:38 > 0:06:42a radio transmitter on the cyclist and a a radio receiver in the car.
0:06:42 > 0:06:45So the idea is that the bike is constantly giving out a signal
0:06:45 > 0:06:48and the car picks up on it hopefully and alerts the driver?
0:06:48 > 0:06:51Yeah, within a 30-metre range.
0:06:51 > 0:06:55Georgia's keen to find out the best design for her airbags on bikes.
0:06:55 > 0:06:58Do you know, like...? If they're light and soft,
0:06:58 > 0:07:00if you land on them, would they not pop?
0:07:00 > 0:07:03The thing with an airbag is, if you look at this,
0:07:03 > 0:07:05what you notice when the airbag goes off,
0:07:05 > 0:07:09it pops out and immediately see how it collapses straightaway?
0:07:09 > 0:07:11Whereas these systems here
0:07:11 > 0:07:15use something different. This is a new technology that's come in.
0:07:15 > 0:07:17What you have is a gas cylinder.
0:07:17 > 0:07:21It's got carbon dioxide inside, like you get in lemonade, OK?
0:07:21 > 0:07:25That fills the bag up, it keeps it up for a long time.
0:07:25 > 0:07:28So then if you came off your bike, you'd still have your airbags on?
0:07:28 > 0:07:33Exactly, yeah. It's still inflated and you're still...protected.
0:07:33 > 0:07:38So Georgia's idea looks like it could progress from putting airbags
0:07:38 > 0:07:42on bikes to airbags on bikers' clothing. Which will she decide?
0:07:43 > 0:07:46Catherine's finding out the best way to operate
0:07:46 > 0:07:48her automatic door securely.
0:07:48 > 0:07:51The important thing about your door is that it only opens
0:07:51 > 0:07:54for the person that's allowed to open the door.
0:07:54 > 0:07:56So I thought we could get...
0:07:56 > 0:07:59the door to recognise a particular password.
0:07:59 > 0:08:03We could have different passwords for different people.
0:08:03 > 0:08:06Can you use it anywhere else apart from your house, like a shop
0:08:06 > 0:08:09- or a business meeting?- Well, that's a really good question.
0:08:09 > 0:08:12I was thinking, when I saw your idea,
0:08:12 > 0:08:15that where it'd be really useful for me would be getting into work
0:08:15 > 0:08:19because at the moment, we have a swipe card system.
0:08:19 > 0:08:22So this is my card to get into the door.
0:08:22 > 0:08:25Of course, I have to swipe it and then I have to key in a pin number.
0:08:25 > 0:08:28So I think that's somewhere where it could be really useful.
0:08:28 > 0:08:32You could use it in hospitals for people who can't use their hands.
0:08:32 > 0:08:36They don't have to touch anything so infection might not spread.
0:08:36 > 0:08:39By thinking of new uses for her invention,
0:08:39 > 0:08:42Catherine could clean up in today's competition.
0:08:42 > 0:08:44Tybalt is right on track with his idea, too.
0:08:44 > 0:08:46The technology exists to make his invention,
0:08:46 > 0:08:49but the challenge is to make it small enough to fit on a bike.
0:08:49 > 0:08:53On a bike, you can't have a power supply or take a laptop with you.
0:08:53 > 0:08:57There's certainly no way that you'd want to mount this. The aim would be
0:08:57 > 0:09:00to smash the design down to something more portable.
0:09:00 > 0:09:03Have you thought about how you would wish...
0:09:03 > 0:09:07the system to, you know, flag a warning to the driver?
0:09:07 > 0:09:10Would it just a beeping, or have you thought about...
0:09:10 > 0:09:13- a visual thing? - Yeah, I thought about warnings
0:09:13 > 0:09:16- like, "Warning, cyclist ahead." - Have you ever been in the car
0:09:16 > 0:09:20and the name of the radio station appears on the display?
0:09:20 > 0:09:23They actually use a technology called RDS, Radio Data Service.
0:09:23 > 0:09:26At the radio station end, they can transmit the name
0:09:26 > 0:09:29of their radio station. When you tune to it, it comes up on your radio.
0:09:29 > 0:09:33So, great news for Tybalt. He can use existing technology
0:09:33 > 0:09:36in car radios to warn drivers of cyclists.
0:09:36 > 0:09:41With only 20 minutes left, I'm off to check on everyone's progress.
0:09:41 > 0:09:44First, Georgia with her airbags for bikes.
0:09:44 > 0:09:47As well as maybe mounting the airbags onto the bike,
0:09:47 > 0:09:50maybe now also putting them on a jacket as well.
0:09:50 > 0:09:52It also uses a gas system, and you were talking about
0:09:52 > 0:09:56the difference with that. Can you remember what that was?
0:09:56 > 0:09:59If you're wearing the suit, if you've come completely
0:09:59 > 0:10:01off your bike, these ones will still be out.
0:10:01 > 0:10:04That's right. So it remains inflated for a long period of time,
0:10:04 > 0:10:07so as you're rolling down the road, this keeps protecting you for each
0:10:07 > 0:10:10- roll, roll, roll, then you're OK. - That's interesting. It sounds like
0:10:10 > 0:10:12you're really coming along with this now.
0:10:12 > 0:10:15- Have you learnt loads from Stewart? - Yeah.
0:10:15 > 0:10:17Meanwhile, Catherine has come up with some problems
0:10:17 > 0:10:19with her voice activation device,
0:10:19 > 0:10:22but has made some alterations that might just work.
0:10:22 > 0:10:25- What have you been doing then, Catherine?- We've been trying
0:10:25 > 0:10:29to set a password and seeing how the voice activation works.
0:10:29 > 0:10:31You're talking about this being in people's homes.
0:10:31 > 0:10:33Is that the only place you see it working?
0:10:33 > 0:10:36You could have it in hospitals or in a supermarket as well,
0:10:36 > 0:10:40cos in a hospital, people might not be able to use their hands.
0:10:40 > 0:10:43If you touch something, it can spread infection,
0:10:43 > 0:10:45so you wouldn't have to touch the door.
0:10:45 > 0:10:48That's a really good idea. That's something that you think,
0:10:48 > 0:10:51why have they not got that already? It makes so much sense.
0:10:51 > 0:10:53Is this kind of technology used by lots of people?
0:10:53 > 0:10:55No, it's not used very much.
0:10:55 > 0:10:57These things are still very much in development.
0:10:57 > 0:11:00But they certainly haven't spread to places
0:11:00 > 0:11:03where they could be really useful, like hospital.
0:11:03 > 0:11:05And Tybalt is exploring further
0:11:05 > 0:11:09how his idea can work with existing car radios.
0:11:09 > 0:11:12Tybalt, please talk me through this. What's going on here?
0:11:12 > 0:11:15We're talking about how FM radio works.
0:11:15 > 0:11:18Something like this, we're taking off-the-shelf components
0:11:18 > 0:11:20to build what is essentially a prototype.
0:11:20 > 0:11:24Does it sound exciting? This talk of a prototype of one of your ideas?
0:11:24 > 0:11:29- Yeah.- I don't want to hold you up, so I'll see you guys later.
0:11:29 > 0:11:32So, what does expert inventor
0:11:32 > 0:11:35and judge, Tom, make of the ideas so far?
0:11:35 > 0:11:39I am dead impressed, actually. You've got three original ideas.
0:11:39 > 0:11:42People say, why didn't I think of that? There's three ideas there
0:11:42 > 0:11:44that you think, why didn't anybody think of it?
0:11:44 > 0:11:46Do you think the key is in simplicity?
0:11:46 > 0:11:50Yeah, there's an interesting use of technology there and these experts
0:11:50 > 0:11:54know their stuff almost as well as the kids do, and it's impressive
0:11:54 > 0:11:56to see technology used in the right way,
0:11:56 > 0:11:59but importantly to solve the problem and that's what it's about.
0:11:59 > 0:12:04Has anything caught your eye so far? I know it's early days.
0:12:04 > 0:12:07Well, I'm a keen cyclist myself, so I obviously have an infinity
0:12:07 > 0:12:09with a couple of the ideas that we've seen,
0:12:09 > 0:12:12but I'm not going to discount the other one as well.
0:12:12 > 0:12:17There's so many applications for the voice recognition stuff, I can see.
0:12:17 > 0:12:19So I'm going to reserve my judgement until the pitch.
0:12:21 > 0:12:24Tom will be judging all their ideas later on.
0:12:24 > 0:12:27He'll want to know well Georgia, Catherine and Tybalt have grasped
0:12:27 > 0:12:30the technology behind their inventions,
0:12:30 > 0:12:32and how well they can sell them to him.
0:12:32 > 0:12:34This here, that's...
0:12:34 > 0:12:37Only one of our budding inventors can go through to the next round.
0:12:38 > 0:12:41The guys are hard at work behind me. But we've already had them
0:12:41 > 0:12:43hard at work, looking at how inventions and ideas
0:12:43 > 0:12:46can be brought into the real world. We sent all three of them off
0:12:46 > 0:12:50to meet Olympic gold medallist and world record holder cyclist,
0:12:50 > 0:12:52Chris Boardman, to see how great ideas
0:12:52 > 0:12:55have made the British cycling team one of the best in the world.
0:12:59 > 0:13:03Great Britain is at the forefront of cycling technology,
0:13:03 > 0:13:06and the GB team won eight gold medals at the Beijing Olympics.
0:13:06 > 0:13:09The team's home is the National Cycling Centre in Manchester.
0:13:09 > 0:13:11Olympic gold medallist, Chris Boardman
0:13:11 > 0:13:15broke three world records here, and was the technical manager
0:13:15 > 0:13:17to the British cycling team at the Beijing Olympics.
0:13:18 > 0:13:22The inspiration to be gained from watching world class riders
0:13:22 > 0:13:26in an environment like this, is watching things being done
0:13:26 > 0:13:28to the absolute maximum, to being pushed always,
0:13:28 > 0:13:30never being satisfied with "That's good enough".
0:13:30 > 0:13:33It's always, "How can it be better? How can it be better?"
0:13:33 > 0:13:39Today, might help me with science and aerodynamics and how bikes work.
0:13:39 > 0:13:41I think it'll help my invention,
0:13:41 > 0:13:45because aerodynamics is involved with bikes.
0:13:45 > 0:13:48I'm looking forward to seeing the bikes and looking
0:13:48 > 0:13:50at how they work and seeing the track.
0:13:53 > 0:13:56Good morning. Welcome to the Manchester Velodrome.
0:13:56 > 0:13:58After the introductions,
0:13:58 > 0:14:00Chris is keen to explain the technology behind the track.
0:14:00 > 0:14:04Any ideas why it's got a slope?
0:14:04 > 0:14:06Does it help people going round sharp corners?
0:14:06 > 0:14:10It does. If it was completely flat, when they got
0:14:10 > 0:14:15to about 30 km per hour, they'd have to REALLY lean over to get around.
0:14:15 > 0:14:18And if the track was flat, they'd probably slide out.
0:14:18 > 0:14:22Their wheels couldn't grip and they'd slide out.
0:14:22 > 0:14:25So they've had to make the track bent like this to bring it up,
0:14:25 > 0:14:28so the riders can get round at speed.
0:14:28 > 0:14:31That's the only way to get around a bend this tight.
0:14:33 > 0:14:36Here, there's a little experiment
0:14:36 > 0:14:40that shows how a bike rider goes around the track.
0:14:40 > 0:14:42If I spin this ball around,
0:14:42 > 0:14:45the energy is trying to push it outwards,
0:14:45 > 0:14:47always trying to push it outwards,
0:14:47 > 0:14:50so it can go around the top of this funnel,
0:14:50 > 0:14:53so long as I keep going at a certain speed,
0:14:53 > 0:14:57and centrifugal force is what helps them to do that.
0:15:00 > 0:15:03It shows you that if you're going fast enough,
0:15:03 > 0:15:06the ping pong ball can go actually around.
0:15:06 > 0:15:09But if you're going too slow, you just drop. Like that.
0:15:11 > 0:15:16The biggest thing that the riders have to overcome is air resistance.
0:15:16 > 0:15:19So the bike has to be a nice, aerodynamic shape.
0:15:19 > 0:15:23This is one of the fastest bikes that you'll find in the world.
0:15:24 > 0:15:27But it's not just the bike that needs to be aerodynamic.
0:15:27 > 0:15:30It's the cyclist's position too.
0:15:30 > 0:15:34I'm now very upright and there's a lot of wind hitting my body now.
0:15:34 > 0:15:36And it's really slowing me down.
0:15:36 > 0:15:40So, I can't do anything about the bike shape, because that's fixed.
0:15:40 > 0:15:42Bit I CAN make me smaller,
0:15:42 > 0:15:46by getting lower on bike and pulling myself down,
0:15:46 > 0:15:49and pull my elbows in.
0:15:49 > 0:15:51I'm probably about 30% smaller.
0:15:51 > 0:15:55And that makes a very, very big difference.
0:15:55 > 0:15:59Chris has got a wheelie good challenge for our inventors.
0:15:59 > 0:16:01He's teamed them up with Carolyn,
0:16:01 > 0:16:03one of the cyclists training at the Velodrome.
0:16:03 > 0:16:05Shall I go around once, and show you what I do?
0:16:05 > 0:16:08And maybe you can give me some tips afterwards?
0:16:11 > 0:16:15Our budding inventors have to put what they know about rider position
0:16:15 > 0:16:18and the shape of the track to the test,
0:16:18 > 0:16:21as they work out a way to try and make Carolyn go faster.
0:16:24 > 0:16:26So, what do you think?
0:16:26 > 0:16:32Erm...you could try crouching down. It'll help your speed.
0:16:32 > 0:16:36And you should go lower on the flatter bits
0:16:36 > 0:16:39and higher on the bends.
0:16:41 > 0:16:44Her first lap was just under 23 seconds,
0:16:44 > 0:16:49so after some expert coaching, what can she do on a second attempt?
0:16:56 > 0:16:57So, what do you think?
0:16:57 > 0:17:03- What was my time?- 18.644 seconds.- Oh, it was over four seconds faster!
0:17:03 > 0:17:05I'm really happy with that!
0:17:07 > 0:17:10It was surprising, because those little changes
0:17:10 > 0:17:12made such a big difference.
0:17:15 > 0:17:18I think it was great to learn about aerodynamics,
0:17:18 > 0:17:20because it can help my invention.
0:17:23 > 0:17:27We're back in HQ and with only 10 minutes left, Georgia,
0:17:27 > 0:17:31Catherine and Tybalt will have to make the most of their time.
0:17:31 > 0:17:35Originally, Georgia wanted to fit airbags on bikes,
0:17:35 > 0:17:38but has decided to put them on clothing instead.
0:17:38 > 0:17:41All she has to do now is inflate it to see
0:17:41 > 0:17:44how it could protect the rider in a fall.
0:17:44 > 0:17:48- Give it a good, sharp pull. - Your coat will come off! - SHE LAUGHS
0:17:48 > 0:17:51Well that's easier said than done. So to make sure Georgia
0:17:51 > 0:17:55doesn't start to feel too deflated, I've come to her rescue.
0:17:55 > 0:17:59- Right, three, two, one. - COAT PUFF UP AIR
0:17:59 > 0:18:01And there we go!
0:18:01 > 0:18:02- That's amazing!- It's good, isn't it?
0:18:02 > 0:18:05And I'm... Feel that.
0:18:05 > 0:18:07I could fall over anywhere.
0:18:07 > 0:18:11- How far will it expand?- That's its maximum inflation now.
0:18:11 > 0:18:16So now, I would have come to a stop long ago, by now.
0:18:16 > 0:18:19So how does it feel, seeing one of your ideas
0:18:19 > 0:18:22- coming into the real world slowly? Pretty impressed with that?- Yeah.
0:18:22 > 0:18:26Catherine is now recording voice commands into special
0:18:26 > 0:18:30voice recognition software that could make her idea a reality,
0:18:30 > 0:18:32as long as she can remember the magic words.
0:18:32 > 0:18:34Open sesame.
0:18:36 > 0:18:38Nine green apples.
0:18:39 > 0:18:40No.
0:18:40 > 0:18:42I've forgotten the password.
0:18:42 > 0:18:44Oh, what was the password?
0:18:44 > 0:18:45Eight pebble bananas.
0:18:47 > 0:18:49Yeah.
0:18:51 > 0:18:55Having found out his invention will work with existing technology
0:18:55 > 0:18:58Tybalt finds out how his idea can be made to work with a car radio.
0:19:01 > 0:19:06Any car radio that picks up your FM signal will spot
0:19:06 > 0:19:08there's a TA flag, a traffic announcement flag,
0:19:08 > 0:19:12and regardless of what it's doing, if it's playing a CD or another station,
0:19:12 > 0:19:14it changes channels to your bike's channel
0:19:14 > 0:19:17and plays "cyclist alert" through the speakers.
0:19:17 > 0:19:20When it goes out of range of the bike it no longer receives the signal,
0:19:20 > 0:19:23so reverts back to what you were listening to.
0:19:23 > 0:19:26Yeah, I think it would work like that and I had suggested that
0:19:26 > 0:19:28but I didn't know how I could do it.
0:19:28 > 0:19:30So essentially it's a mechanism
0:19:30 > 0:19:34that allows your bike to interrupt the car radio.
0:19:34 > 0:19:37And play an announcement specifically to that car.
0:19:37 > 0:19:39With time up Georgia has found out
0:19:39 > 0:19:43the best way to protect cyclists with airbag technology.
0:19:43 > 0:19:46Catherine has developed further uses for her idea
0:19:46 > 0:19:48hoping to use it in hospitals.
0:19:48 > 0:19:52And Tybalt knows he can use existing car radios to make his idea work.
0:19:52 > 0:19:55But whose invention will impress Tom the most to win a place
0:19:55 > 0:19:58in the next stage of the competition?
0:20:02 > 0:20:05All three of our budding inventors now have to pitch to Tom.
0:20:05 > 0:20:07First up, it's Georgia.
0:20:07 > 0:20:09Good luck, we'll be rooting for you.
0:20:09 > 0:20:10Off you go.
0:20:13 > 0:20:16Will Georgia be able to impress Tom
0:20:16 > 0:20:18with her idea of airbags to protect cyclists?
0:20:18 > 0:20:22Will she be able to persuade him that she has the winning invention?
0:20:23 > 0:20:27- Hi, Georgia. How are you?- I'm really good but nervous at the same time.
0:20:27 > 0:20:31I'm looking forward to learning about your airbags for bikes.
0:20:31 > 0:20:32Can you explain the idea?
0:20:32 > 0:20:37It's changed, and instead of having it on the bike
0:20:37 > 0:20:41put it in a normal jacket, a normal jumper,
0:20:41 > 0:20:43- that you'd normally wear...- OK.
0:20:43 > 0:20:50And then have gas containers which have CO2 inside,
0:20:50 > 0:20:52so if you fall, or trip,
0:20:52 > 0:20:55there's a sensor that senses it,
0:20:55 > 0:20:58and then it'll go off and you won't hurt yourself.
0:20:58 > 0:21:01So you were saying when you fall off the bike
0:21:01 > 0:21:03the CO2 canister's triggered,
0:21:03 > 0:21:06and that inflates the airbags.
0:21:06 > 0:21:09What happens? Do they stay inflated?
0:21:09 > 0:21:13They stay inflated because the CO2 is different from an airbag.
0:21:13 > 0:21:18- Cos airbags have holes in that let all the air out straightaway.- OK.
0:21:18 > 0:21:21But the CO2 just stays for quite a while.
0:21:21 > 0:21:23OK. And why have you designed that feature into it?
0:21:23 > 0:21:27Erm, because if you came off your bike on a hill,
0:21:27 > 0:21:29you'd just roll and roll.
0:21:29 > 0:21:32If you were tumbling it stays inflated and would still protect you?
0:21:32 > 0:21:34- And it wouldn't hurt. - A very good idea.
0:21:34 > 0:21:37So it could be for joggers, people on horses,
0:21:37 > 0:21:39you could use it for all sorts of action sports.
0:21:39 > 0:21:41A great idea. Thank you very much.
0:21:41 > 0:21:43It was a brilliant pitch, and I wish you luck.
0:21:43 > 0:21:45OK.
0:21:47 > 0:21:50When I was walking I was a bit scared
0:21:50 > 0:21:54but when he started talking halfway through it was OK.
0:21:54 > 0:21:58Tybalt is next up with his bike bleeper invention.
0:21:58 > 0:22:02Will he convince Tom that he should go through to the semifinals?
0:22:02 > 0:22:06Hi, Tybalt. I'm looking forward to learning about the bike bleeper.
0:22:06 > 0:22:08Can you explain the idea to me?
0:22:08 > 0:22:09I invented the bike bleeper
0:22:09 > 0:22:13cos a friend from school was knocked off his bike and killed.
0:22:13 > 0:22:17When the car comes into the 50-metre range
0:22:17 > 0:22:22the car will bleep, the device in the car will bleep.
0:22:22 > 0:22:24OK. Can you explain a little bit, perhaps,
0:22:24 > 0:22:27about the technology as to how it might work?
0:22:27 > 0:22:33There is a radio receiver in the car and a radio transmitter on the bike.
0:22:33 > 0:22:36And it's folded away in a little box on the bike,
0:22:36 > 0:22:40but can clip onto the handlebars and can go on the dashboard on the car.
0:22:40 > 0:22:45Has the idea improved at all since you spent time with the expert?
0:22:45 > 0:22:47Yes.
0:22:47 > 0:22:54I didn't know there was an existing radio receiver in the car
0:22:54 > 0:22:56built in the car in the radio.
0:22:56 > 0:23:01So that radio receiver is just in a regular radio in a car
0:23:01 > 0:23:03and every car's got a radio in it.
0:23:03 > 0:23:07So, in effect, the bleeper that would be on all bikes, or most bikes,
0:23:07 > 0:23:10would talk to almost all cars.
0:23:10 > 0:23:12That's a really, really good idea.
0:23:12 > 0:23:14Thank you.
0:23:14 > 0:23:16Have you thought about what might happen
0:23:16 > 0:23:19if drivers don't have their radios on, for instance?
0:23:19 > 0:23:22Would the technology still work?
0:23:22 > 0:23:25Erm, no, that's the only thing why buying on would be good.
0:23:25 > 0:23:28I think it's very honourable that you're doing something
0:23:28 > 0:23:30that could potentially save lives.
0:23:30 > 0:23:34I think you've done a really good presentation, thank you very much.
0:23:34 > 0:23:35Thank you.
0:23:35 > 0:23:37With Tybalt's pitch over Catherine's up next
0:23:37 > 0:23:40with her voice-activated door system.
0:23:40 > 0:23:44Will Tom be persuaded that she should go through to the semifinals?
0:23:44 > 0:23:48Remember, Tom's not looking for a completely finished idea today,
0:23:48 > 0:23:51he's looking for an idea that has the most potential.
0:23:51 > 0:23:54he'll judge them on the technologies they've mastered
0:23:54 > 0:23:58- and how well they can explain their idea.- Catherine, how are you?
0:23:58 > 0:23:59OK, thank you.
0:23:59 > 0:24:02Good, good. I'm looking forward to learning about your idea,
0:24:02 > 0:24:04for a voice-activated door.
0:24:04 > 0:24:07Can you explain the concept to me?
0:24:07 > 0:24:10Well, you talk into the sensor there,
0:24:10 > 0:24:13and then it'll recognise your voice,
0:24:13 > 0:24:15and you can also make a new password there.
0:24:15 > 0:24:18And the door mechanism will make the door open,
0:24:18 > 0:24:19and then you walk through.
0:24:19 > 0:24:23So you walk up to the door, you say, "open sesame", or "this is my house"
0:24:23 > 0:24:25or "I live here" or "I'm so-and-so",
0:24:25 > 0:24:29- and it recognises your voice and the door...- Then you say a password.
0:24:29 > 0:24:33You say a password as well, so that encrypts it so it's specific to you,
0:24:33 > 0:24:36and the door opens for you.
0:24:36 > 0:24:38Mmm, very interesting.
0:24:38 > 0:24:42Where did you get the inspiration for this from?
0:24:42 > 0:24:44It was one night and my mum went out of the room
0:24:44 > 0:24:47- and she came back with a tray full of drinks.- OK.
0:24:47 > 0:24:50And one of us had to get out our comfy chair to go and open the door.
0:24:50 > 0:24:53- OK.- And then after that we said that it would be really good
0:24:53 > 0:24:56to have just a door that said, "open sesame" and it would open.
0:24:56 > 0:24:58Who will benefit from the idea?
0:24:58 > 0:25:01- Well you could have it in a home, like I've said.- Yeah.
0:25:01 > 0:25:05Or in a hospital as germs spread easily when you touch surfaces.
0:25:05 > 0:25:07Now that's an interesting idea.
0:25:07 > 0:25:10So, if it would recognise your voice,
0:25:10 > 0:25:13how would it recognise your voice and not my voice, for instance?
0:25:13 > 0:25:17You'd have to train it, like say into it if you were cross,
0:25:17 > 0:25:20and you'd have to say into it if you were happy.
0:25:20 > 0:25:22OK. So you'd record your voice into it,
0:25:22 > 0:25:25it would then recognise the kind of pattern of the sound of your voice.
0:25:25 > 0:25:28- Yes.- It would remember that... - Yes.- ..then know it.
0:25:28 > 0:25:31Thank you very much, a really good presentation. Well done.
0:25:35 > 0:25:38So, with the pitches over who has impressed the most
0:25:38 > 0:25:40to book themselves a place in the next round?
0:25:42 > 0:25:46Will it be Georgia's idea for airbags?
0:25:46 > 0:25:48Tybalt's bike bleeper device?
0:25:50 > 0:25:55Or Catherine and her voice-activated door system?
0:25:55 > 0:25:58Tom, three more strong ideas today.
0:25:58 > 0:25:59How did they do?
0:25:59 > 0:26:02They did brilliantly. I'm so impressed.
0:26:02 > 0:26:04You've got three great ideas,
0:26:04 > 0:26:07they've all taken on board the advice the experts have given
0:26:07 > 0:26:09and pitched really well too.
0:26:09 > 0:26:12It must have been really difficult to make a decision but have you?
0:26:12 > 0:26:15- I have.- OK, shall I get the young inventors in then?
0:26:15 > 0:26:16Do it, Johny.
0:26:16 > 0:26:18- Tom, if you'd like to take a seat. - OK.
0:26:18 > 0:26:21It's crunch time.
0:26:21 > 0:26:25They've all spent time developing their ideas and pitched them to Ton
0:26:25 > 0:26:27but who has won that place in the semifinals?
0:26:27 > 0:26:30How are you doing, guys?
0:26:30 > 0:26:31Nervous.
0:26:31 > 0:26:32Bit nervous.
0:26:32 > 0:26:35You've done so well to get this far.
0:26:35 > 0:26:36But Tom has come to a decision.
0:26:36 > 0:26:39So, Tom, it's over to you.
0:26:39 > 0:26:43Yeah, you've done brilliantly to get this far, you really have.
0:26:43 > 0:26:45Georgia, I thought your idea was fabulous,
0:26:45 > 0:26:49I loved the way that you've addressed road safety
0:26:49 > 0:26:51and making cycling safer.
0:26:51 > 0:26:53I do worry about if it's something
0:26:53 > 0:26:56people would actually wear on a day-to-day basis.
0:26:56 > 0:26:58Tybalt, it's a great idea as well.
0:26:58 > 0:27:02The solution seems interesting. Especially going through the stereo
0:27:02 > 0:27:05but what'd happen if people don't have their radio on?
0:27:05 > 0:27:08Catherine, a great idea as well.
0:27:08 > 0:27:11And I'm particularly impressed by the journey it's taken,
0:27:11 > 0:27:14how it's evolved from something that works in the home
0:27:14 > 0:27:16that could work in hospitals and areas like that.
0:27:16 > 0:27:20It's a difficult decision for me to make.
0:27:20 > 0:27:22It's a difficult decision, Tom.
0:27:22 > 0:27:25But it's a decision that you've got to come to.
0:27:25 > 0:27:26So I'm going to ask you,
0:27:26 > 0:27:31which genius idea is going through to the next round, the semifinals?
0:27:35 > 0:27:39It's Tybalt.
0:27:39 > 0:27:40How does it feel?
0:27:40 > 0:27:41It feels really good.
0:27:41 > 0:27:44So, Tybalt wins with his bike bleeper.
0:27:44 > 0:27:47And he's still in with a chance of winning My Genius Idea.
0:27:47 > 0:27:50All that's left to say is join us next time
0:27:50 > 0:27:52as we look for another genius idea.
