Anthony, why did you pick something the best platform and develop that. Well, we wanted to pick across the desert, If you and I were racing and you're in a car and I'm on a motorcycle

you could keep up with me. there's no way but 15 years from now So, yes, it's difficult, that's out there. it's going to be the fastest thing by itself? So how does a motorbike stay upright to tell you, but... Well...I'd love to be able Anthony, can you please fill us in? adjusting the steering set-up, Well, it's all about constantly so we have a DC set-up servo, we have encoders for speed, Hama drive, DC motor encoder, and...you do the math.

Can I explain to both of you how it works. Okay, so... Anthony's dream is on the line, and no wonder he's nervous. Here's what happened last year.

ANNOUNCER: And off we go. Good try, guys.

Today's first official run looks like a disaster waiting to happen. The GPS still has problems and the tyres have left the tarmac. It recovers, but in the next few seconds, we've all got our hearts in our mouths.

That was very scary, and GhostRider still has to negotiate that last bumpy hundred yards to the finish line. Success! So, what's the verdict? In the best military tradition, our two scrutineers refuse to either confirm or deny. The bike did everything that was asked of it

and Anthony's sure they've made a good impression. You must be happy? I'm very happy, yeah. I think overall it was a success. And the latest update? Team GhostRider received the thumbs-up to have a crack at DARPA's $2 million.

UP-BEAT TECHNO MUSIC Ah, New York City. A place of vibrancy, colour and, above all, people. More than 8 million people live in this city, speaking more than 160 languages in ethnic villages around the city. Wouldn't it be great to know what they were all saying?

And this gadget will tell me just that. It's called Interact. It's a voice-to-voice translator and could be my ticket to a tour around New York.

English is a second language for a lot of New Yorkers. My friend here is from Morocco. He speaks Arabic. He's going to give me a tour around New York City. And we're going to put the Interact translator to the test. You need a laptop, tablet PC or Internet-enabled PDA loaded with the software. Plug in a headset, then record your voice

to enable the speech recognition software to respond to your commands. Wake up. COMPUTER: English speech recognition enabled.

Please take me to Central Park. Interact logs phrases in English and also displays a written translation before delivering a verbal one. (computer speaks Arabic)

DRIVER: Yeah, sure. 59th Street and 5th Avenue. The voice recognition software only allows it to translate one way. This is Central Park. Do you want me to go through? HAYDEN: Yes, please.

Not bad, this thing. Fantastic with a kid. If you're travelling around, you can take one of these with you, you could basically be in the country of the language that's programmed into it,

you could find out where to go, get a hamburger, get a meal,

get to anywhere you wanted to go. It will cost about $1,200 and speaks about 10 common languages, and soon, if you're online, you can scan documents and it will transcribe them. (computer speaks Arabic) And it's easy to learn from Interact. (speaks Arabic) (speaks Arabic) Thank you.

Korean barbecue, here I come. Interact coped pretty well with Arabic. Let's see how it goes with Korean. So now it's just a matter of selecting Korean instead of Arabic

and simply placing an order.

Seaweed soup... ..and chicken. Translate. (computer speaks Korean) (laughs) Yes. The more you use Interact, the more familiar it becomes with the way you speak, in turn reducing errors in translation.

Five dishes.

Thank you. Thank you. Interact recognises individual words... Thank you. ..unlike other systems that only respond to common phrases. Translate. (computer repeats 'thank you' in Korean) Thank you. It'll soon be available commercially. COMPUTER: English speech recognition disabled. I, uh, I think I'm ready to eat.

Next, the 13-second X-ray which could mean the difference between life and death in an emergency room.

And later, could this gadget hold the secret to Olympic gold? I just want you to lower it a little bit more around the catch.

And that means trouble.

CAROLINE: On September 11, 2001, when a hijacked plane slammed into the Pentagon, the worst casualties of the terrorist attack were sent here, to the Washington Hospital Center. The trauma unit coped well, but it was stretched to the limit.

Here in the trauma room, time is very precious. Doctors talk about the golden hour - that critical 60 minutes following serious injury. Get diagnosis and management on track during this time and you dramatically increase your odds of survival. With a massive emergency and multiple victims, things get complicated.

Each patient usually needs to be X-rayed to assess the extent of their wounds and to discover any possible internal injuries. Radiology boss Dr James Jelinek knows how important these X-rays are. People die from massive internal bleeding from a pelvic fracture, yet if you don't know in the early aspect of the patient's care that the pelvis is fractured, no matter how good you are, if that's not taken care of, that patient won't make it.

WOMAN: Just the chest... Okay.

The trouble is, X-rays can create a major bottleneck in emergency care. They might take up to 20 minutes to process, and each patient needs to have several done. Traditionally, X-rays only produce an image that's so big, so if you want to create a panorama of the whole body,

you have to take multiple X-rays, and that all takes plenty of time.

Time and trauma are very much critically related. If you've got six patients, and the ordinary time it takes to image one patient is 15, 20 minutes, I wouldn't wanna be the sixth patient. If you can kind of stand at attention like a soldier, like you're doing, and hold that position, we'll get a pretty picture, okay? But that X-ray department logjam is a thing of the past at this hospital, thanks to a revolutionary new X-ray machine

that is literally a life-saver. It's a wonderful machine. It's an incredible leap of technology compared to what we've had before. This breakthrough in emergency care is called the Statscan. It can take a low-radiation digital X-ray of the whole body in just seconds, and it comes from a surprising place. Interestingly enough,

this technology had its origins over in the diamond mines in South Africa. Any workers who couldn't quite resist the temptation of a few sparkly souvenirs were quickly picked up by a fairly controversial total body X-ray scan. Diamonds could be very easily spotted, even if they'd been swallowed. The Statscan's ability for quick detection is desperately needed

for the trauma unit's newest patient. 69-year-old May McLean rolled her pick-up and may have internal injuries. Any resulting blood loss could be fatal. The Statscan gives an instant snapshot of May's injuries. Two sweeps of the scanner beam record May from head to toe. So a full body X-ray can be done in just seconds.

It's a quantum leap in trauma care technology. This thin pencil beam is used to scan the entire body, to give us X-ray qualities that really are not only spectacular, but we can actually scan the entire body in 13 seconds... Wow. That's... ..which, compared to ordinary time, would take 45 minutes. Only moments after her 13-second scan, a digital X-ray of May is available on a computer monitor.

Here you're seeing the patient's humerus, which is the long bone of the upper arm. Clearly there's a fracture. May's main injury is a fractured arm, so she's been relatively lucky. Dr Christian Corwin can zoom in on any part of her body. She wasn't wearing a seat belt... And contrast can be altered to look at either bones or soft tissues, like lungs. Two minutes in the scanner we've quickly identified the injuries that we need to deal with

and ruled out some more potentially life-threatening injuries that we could quickly fix. This is only the fifth Statscan installed in a US hospital. They cost about $600,000 and they're a lot safer for patients and staff. The narrow beam cuts radiation exposure by up to 75%, compared to old X-rays. This is a very thin -

probably no more than three or four pieces of paper thick - beam where the X-ray would come out. And it comes down to here, which is our detector, and it's tightly narrowed so that there's no stray radiation

going outside the area we want to cover. Old-style X-rays are large, creating spill areas and subjecting parts of the body to multiple X-ray exposures. The narrow beam of the Statscan lessens spill

and means each part of the body is only subjected once to X-rays. When you can get one patient done in a matter of seconds, then everyone's ability to take care of more patients is enhanced. Thanks to the Statscan, May has been cleared of serious injury in record time. Being able to know that there's really nothing seriously wrong that quick is nice,

so then we can start worrying about things like her family, whether or not she's in pain, get you something to eat or drink. This ground-breaking technology is improving patient care.

And the Washington Hospital Center is better prepared for any future emergency. It's a tremendous sense to know that we can not only take care of these patients faster, but do it better. In fact, we're really practising state-of-the-art medicine. So we're talking about saving time and potentially saving lives as well?

Better images, shorter time, and hopefully, that results in saving more lives. Knock, knock, look what's here - the ultimate home delivery. A block of apartments built in less than a week. This I've got to see. Adam and Jamie go to new heights to test a knock-out myth -

In heavily populated cities around the world, urban sprawl and the demand for affordable accommodation

is a problem with no quick fix. London, with its 7 million people, is a perfect example of how a city suffers from a housing crisis. But as the desire for inner-city living grows, the London suburb of Camberwell has become the perfect location for young, fast professionals to live close to the city,

but without the high cost. So, it needs fast housing. Thanks, mate. And believe it or not, in just nine days, there'll be a complete set of units right there. It's a revolutionary modular system known as Buma housing, developed in Poland. And the innovations start at ground zero. Now, these might not look like much,

but they're incredibly important. This particular design has its own patent. This is the footings of the buildings. They get screwed down and go down to a depth of 5m to 6m.

When they get to their location at the bottom, they send out anchors, and that's what makes them so solid. And if you wanted to dismantle the buildings and relocate them, you could take the footings as well.

They unscrew, and off they go. So once the footings are sunk,

a convoy of semitrailers make a three-day journey from Poland to lead a military-like assault. If you look how long this vehicle is, getting it into these small locations can be difficult. So what they've done is they've got movement in these back axles. The back axles actually can steer and you've got a guy down the back here with a remote control, works with the driver,

and that's how we're going to get it in. Stop! This is a two-bedroom module. This is about to go up right now. Every one of these modules is half of the flat. Each module is built around a light-gauge steel frame. The walls are three layers thick and heavily insulated against sound and the elements.

What makes this system unique is that the interior is fully fitted in the factory, and they start from just $150,000.

The building is the shortest part of the process, which is pretty amazing, really. These things have got mirrors, kitchens, carpets, already in them as they arrive. To build these apartments conventionally would take a year,

with 10 trucks a day in these narrow streets. It's a solution to the urban sites which cause such an incredible inconvenience, um... ..to the urban environment and to the local community. This is certainly the way forward. And the neighbours are happy. I don't know about the connection and the soundproofing, I don't know about the technicals on it, but as a principle,

I think it's the way it could've been done 25 years ago. It's amazing. It's fantastic. I totally agree. And it's good, and it looks clean. I think it's actually physically quite easy to keep looking good. A total of 18 modules will complete this three-storey complex. They simply bolt together and then it's just a matter of connecting water and power. Ah, look at this.

Everything in this place is great. The doors are fire doors, good quality... ..and a fully-fitted kitchen straight off the back of a truck. Great benchtops, cupboards, stainless steel appliances, plumbing's already in there for your dishwasher and washing machine. It is fantastic. All the tiling's even done here. Look at this. Stainless steel sink, here's your living area, eat-in kitchen...

This is where the two modules actually join, just here. Now, this'll be filled with concrete, then up the sides here they'll plasterboard this in, skim it with a bit of plaster. You'll never know that those two modules were ever joined. Brilliant stuff. From this... ..to this, in a little more than a week. With government funding, Buma apartments are currently rented to key workers,

like nurses and police. So what's instant housing like to live in? DOORBELL RINGS Who is it? Hello, Zene, how are you going? Hey, Marcella, how are you? Very good. How are you? Very well... Marcella is a social worker and it's the only way she could afford inner-city living. It's just a great space too, isn't it? On the back of the truck, they didn't look as big as this,

and they really are quite spacious inside. And warm? Yes, yes. Yes, they are, actually. What I found this winter when I moved here, we rarely had the heaters on. So they're well insulated? Yes, yes. Door windows. Yeah. How does that work? Let me show you. You can have it as a door? You can have them as a door to get out to the balcony, or...

ZENE: The wind's coming in. Yeah. You can just pull them down. Have it as a window. Yes. That is really good, isn't it? So great for security. It may be London's latest just-add-water answer to low-cost rental housing, but in the future, you might buy them off-the-shelf one week and install them the next. Now, that's real home delivery!

one of the great campuses of America's south. Steeped in history, tradition and old-world charm. But Duke is also a university of the future, where cutting-edge technology is creating a learning revolution. And there's only one way to really put it to the test. It's my first day back as a university student, so I had to buy all the gear.

Got the Duke University sweatshirt, got the bag, the book lists, pens, paper, everything I'd normally have, but here - check this out - every student here has to have one of these - a remote control. And this is the weird thing - Every student has an iPod. These are portable music players - sort of thing a university would normally ban, you'd think. But here, they're using them for educational purposes. This is going to be fun.

Instead of fighting the distractions of new technology, Duke is embracing them. In a trial this academic year, 1,650 iPods were handed out to new students. But you won't find one song on their 20GB hard drives. Believe it or not, these students are hard at work studying. ..distance and direction...

How do I find what we're listening to now? Firstly, you turn it on like that. Where is it? (laughs) Under.... iPods are in the classroom and on the curriculum, pre-loaded with campus information and used for everything from language lessons to recording and downloading lectures. So these are the ways in which this sound, right, relates to other sounds. iPods are being put to other creative uses.

Like here in Computer Engineering, where pulse rates are recorded and manipulated using computer analysis. Now, the best thing about an iPod, I reckon, is you can skip classes. All the lectures are recorded, I can download them onto the iPod and listen to them at my leisure. Gives you more time to do what being a student's really all about -

doing coffee. You've heard of interactive TV. Well, this is interactive teaching. First-year physics - this brings back memories. In another Duke University trial, each freshman in this class has their own remote control. The college calls it personal response system - PRS. This is a lecture where I use this, right?

Yes. Good. This is a somewhat challenging, harder-than-average PRS question. Students buy a remote from Duke for $35 and PRS polling is used to gauge their understanding during lectures.

Is the image on the retina, the size of the image, getting bigger or getting smaller, or is it staying the same? We've got to answer this now, right? Yeah, he has this on the screen, and you turn it on,

and there are transmitters around the room, and you pick whatever number you want as your answer and you point... Point it there. So what's the answer? (laughs) Each student response is registered and results are instantly tallied, giving the lecturer a clear picture of class progress. That is the correct answer. For the quarter of you who weren't sure how to get the answer,

or chose the other one, let me quickly walk through what's going on. Individual votes aren't identified. This anonymous polling takes the pressure off students fearful of giving the wrong answer, promoting class discussion and teacher-student interaction. These things are great. You really do get the feeling that you're participating in the lecture, rather than just being talked at. And studies show participating does increase learning. Probably would've turned up to more lectures myself if they had these

back in my day. At first, staff thought the remotes were just another teaching gimmick. Now most, like physics professor Henry Greenside, believe they're an essential teaching tool. First of all, I get an immediate sense of whether I've been communicating successfully with the class. How would you get that feedback normally? You'd have to wait until the end of class, until a quiz, then it's two weeks later, and you've lost the moment.

That's the end of the lecture. Imagine staring at an object like this and being able to move it just by using the power of your mind. Or perhaps turning off your TV, or opening your garage door just by thinking about it. In other words, using your mind as a sort of remote control. Well, it's not science fiction,

and thanks to some very clever technology, it's now one step closer to reality. Four years ago, Matthew Nagle was the victim of a stabbing attack. It's says, "Hi, we'll talk soon." He was left paralysed from the neck down, confined to a wheelchair for the rest of his life. After my injury, I was depressed for two years.

Very, very depressed. But today, medical science has given Matthew something he thought he'd lost forever - a taste of independence. Going to open the first email, which says "Congrats". It says, "You are doing a great job." Matthew is controlling his computer cursor through a high-tech device that is actually reading his mind. It's called 'BrainGate'.

I use my brain... I just thought it. I said, "Cursor, go to the top right," and it did, and now I've got control of it all over the screen. That's wild. BrainGate is being developed by a team led by Dr John Donoghue at America's New England Sinai Hospital.

Our basic science question was, "How do you turn your thoughts into action?"

We were very interested in how you think about making a movement and then how the brain computes that or changes it into something that makes your muscles move the way you want to. What we've done, is we've been able to successfully tap into the brain and read out that message that's coming out. And what's a big surprise is how straightforward that signal is. And here's what makes it all possible -

a tiny computer chip studded with 100 electrodes. This is surgically placed 1mm into the surface of the brain area that's responsible for movement. These sensors pick up electrical signals from the brain, which are then fed into a computer where software interprets their meaning. And that's when the magic happens. MATTHEW: Next, I wanna turn on my television. COMPUTER BLEEPS

Just by concentrating on what he wants to do, Matthew's brain becomes a virtual remote control. I'm going to channel down. That's channel down, now I'm going to channel up.

There's channel up. Even more remarkable, and the ultimate aim of the BrainGate project, giving people with quadriplegia the power of movement. Matthew imagines he's moving his hands.

The sensors relay the message to an artificial limb. Open. Close. Not bad, man. Not bad at all. I think a more ambitious goal is that this kind of... ..these kinds of devices kick off a whole new age of neurotechnology developments in which we can create medical devices

that can be put into or onto the body. Next, I'm going to paint a circle. For Matthew, he's just happy mastering the finer points of his remote. That's the best circle I can do, and I'm going to exit. I'd just like to tell those people in wheelchairs to hold on -

'cause there's better...things are going to get better, you know. Imagine you're walking beneath a very tall building and someone drops a coin off the top. Are you dead or alive? Adam and Jamie jump, blast... BANG! ..and even risk their butts to find out. WHOOSH! Oh! (laughs) That hurts!

MAN: Excuse me! Hey, mate! CAR HORN HONKS Could I get a cappuccino and a latte, thanks? Now you can get cafe-quality espresso coffees in your car using freshly ground Arabica beans and freshly frothed milk. They're so good, you'll think someone else made them.

If you drop a coin from a tall building - even something small, like this American penny - will it develop enough speed to cause serious damage or even kill someone, when it hits the ground?

JAMIE: The myth is that if you throw a penny off a building this height, that it'll either get going so fast that it'll embed itself in the concrete at the base of the building, or it'll hit somebody in the head and kill them. But they have to know how fast it'll fall. In other words, its terminal velocity.

To test this myth, Adam takes to the sky.

ADAM: Whoo-hoo! They know a person's top speed is nearly 200km/h.

Adam reckons by dropping a handful of pennies, he'll see what their terminal velocity is relative to his own fall.

What did the pennies do when you let them go? They slid right out of my hands. I opened one hand, then the other, and the pennies just shot out towards the sky. Other than that, I was travelling way faster than they were. Now for some real science. Using a penny wind tunnel, he figures that a dropped penny's top speed is around 60 miles - or 100 kilometres - an hour. This matches the math, the complex equations we have showing the velocity. We should go for a worst-case scenario. Worst-case scenario equals top speed. So Jamie figures the staple gun is the best way of firing a penny. GLASS SHATTERS

Whoops! (laughs) We should get out of here. That's mercury vapour.

Well, the good news is, it works. Next, Jamie builds a penny speedometer. Okay, firing. BANG! The penny travelled one metre in 16/500ths of a second. That's around 100km/h. Look, you can see the penny imprint. Oh, my God!

Damn. That is some serious impact there. Now, remember, the myth is a penny falling at top speed

will penetrate concrete, asphalt or possibly someone's skull. BANG! No penetration here. But what about flesh and bone? The boys have a couple of options. Norma, Adam's ballistics dummy. Lights. BANG! Perfect hit. The penny broke through the thin layer of ballistics gel, but the skull is intact. Second option, each other. So, you ready to put that to the ultimate test? Try and catch it in your hand? The penny is leaving an imprint in the concrete when it hits, so, you know, I'm a little hesitant about catching it, actually. ADAM: I'll do it. JAMIE: Okay.

(high-pitched voice) Ooh! I'm scared. Okay. Three, two... ..one. OW! (laughs) That didn't actually hurt that much. It stings, but there's no bruising or broken skin. Well, I always enjoyed seeing Adam in pain. I'm not sure what it is. Go ahead, shoot me in the ass. Come on, I can take it.

WHOOSH! Oh! (laughs) Ow. Oh, man. Ouch! (laughs) Oh... JAMIE: Well, you said I could. So, you made that great gun, we made the pennies go 64mph. What did we end up with? Well, it didn't penetrate the asphalt, it didn't penetrate the concrete, it didn't penetrate the skull of the ballistics dummy and it didn't hurt your butt. Thank goodness. I mean, it kinda stung when we hit the bones on our hands, but, you know, the myth's not looking good. But these boys never give up. Now, they want to find out how fast a penny has to go to cause some serious damage. Adam's using a high-powered rifle. This should give it some real bang.

Alright. Firing.

BANG! That's like a bullet. That's the speed of a bullet. The coin still didn't end up embedded in the block. Even at supersonic speed, a penny weighing just 2.5g simply doesn't have enough mass to break through concrete or bone. Eliminating all the things that are in the penny's way

from just reaching the ground, 64mph just wasn't enough to cause any kind of damage to a person. And then, when we made it go almost three times the speed of sound, it still wasn't enough to break the bones. Yeah, the worst I can come up with is if you were looking straight up in the sky and got hit in the eye, it probably wouldn't be good for you, but even then I don't know whether it'd take your eye out. We've busted the heck outta this one. Myth busted. Yes. Next time, how clean is your bathroom? Adam and Jamie test the myth that airborne nasties will find their way into every nook, cranny and toothbrush. The race for glory at the next Olympic Games is on. And better use of technology will determine who gets the gold.

ANNA: To be a top-class rower, you need strength, stamina and precision teamwork. Their technique needs to be so critically honed in training that it becomes second nature in a race. Lake Karapiro is home to New Zealand's national rowing squads and it's here that they're using technology to see their training through very different eyes.

Now, rowing is not as simple as it looks. First of all, these boats are built for speed, not stability. Rowers sit on sliding seats which let them increase the length and force of the stroke. The blades have to enter and leave the water cleanly, and each member of the crew must be in perfect unison. It's the coach's job to get a crew up to speed. He has to pick up any problems with technique and correct them. The real problem for the rowers is they can't see what he's talking about.

Dr Clara Soper from Auckland University of Technology has solved the problem with a clever marriage of video technology. She's developed a pair of video goggles

that lets these rowers see exactly what their coach is talking about

as it's happening. The technology of video goggles isn't new. In fact, these are an off-the-shelf item that you could buy for watching DVDs at home. It was integrating them into a wireless system linked with a camera that opened up the possibility of using them for sports training. Rowers wear the goggles, which are fitted with two small monitors and a receiver.

The training session is videoed from the coach's perspective. Just relax a little bit more coming into the catch. Just want you to flow a little bit more around the catch, around that front turn. You're a bit jerky at the moment. A transmitter on the camera sends a video signal back to the goggles. An added bonus of the set-up - the rowers wear an earpiece and can hear instructions straight from the coach's mouth.

It's immediate feedback that helps these athletes make the subtle changes to their technique. Come up onto your feet a little bit. Can you feel yourself come up on your feet? Champion rowers Nathan Twaddle and George Bridgewater have been training using the video goggles for three years now. The goggles have become an integral part of each session. COACH: That's better. That's a better change. That's flowing a little better. And just keep working on that. Well, I'm not exactly a world-class rower, like David here, who's part of New Zealand's national squad, but let's see if I can improve my technique with the help of the video goggles. COACH: Anna, just try and bring the hands flat through. Straight lines. Just try and chop the tops off your knees with your hands... I have to be honest. It's a very weird feeling.

As soon as the goggles go on, there's a battle between your eyes and your brain. The monitors only come into focus millimetres from the eyes. Each eye is seeing a separate image which my brain interprets and registers as a single image. But the biggest challenge is getting used to the idea that I'm facing one direction and seeing myself from a side view. It's a visual contortion that takes some getting used to.

Okay. Well, that was really disconcerting. Dave tells me that as you get better at rowing, you actually feel the stroke in your hands and your feet, but at my level, I just wanna use my eyes. It's a revolutionary way of coaching. For rowers at the top level, the video goggles will add a competitive advantage to training sessions. That's it for 'Beyond Tomorrow'. I'm off to think of more ways to make a car drive a couple of hundred miles all by itself, 'cause, I tell you what, that $2 million sounds pretty alright.
