This week, big space on a small budget. Small hairdryers on a big | :00:00. | :00:16. | |
budget, and the big camera on no budget at all, because it is not for | :00:17. | :00:18. | |
sale. Our dreams of exploring the great | :00:19. | :00:47. | |
beyond have always been governed by very earthly concerns. Things like | :00:48. | :00:57. | |
resources and safety. I want to go there, actually I think that is a | :00:58. | :01:03. | |
dead pixel. The problem of course with sending stuff into space is | :01:04. | :01:07. | |
that it is exceedingly expensive. Since Nasser was founded in 1958, | :01:08. | :01:10. | |
they have spent more than 800 dollars on it. One of the reasons is | :01:11. | :01:17. | |
that most things space related get sent up, then either stay up or burn | :01:18. | :01:23. | |
up. If we ever want to get out here, things are going to have to get a | :01:24. | :01:30. | |
lot cheaper, for a start. One way to make things cheaper is to reuse | :01:31. | :01:40. | |
them. NASA had a go at this with the shuttle programme. The idea was to | :01:41. | :01:43. | |
get it down to tens of millions per flight, but you know how these | :01:44. | :01:50. | |
things go. The shuttle programme was retired in 2011, and now the | :01:51. | :01:58. | |
gauntlet has been passed to the commercial act, Spacek. They have | :01:59. | :02:01. | |
been trying to make their rocket reusable for some time, but it has | :02:02. | :02:06. | |
not been without its challenges. In April this year, they finally did | :02:07. | :02:10. | |
it, succeeding in touching down on their autonomous drone ship, of | :02:11. | :02:20. | |
course, I still love you. That is the name of the ship, by the way. | :02:21. | :02:24. | |
But I do still love you. The challenge was to reuse the ship, | :02:25. | :02:28. | |
something Elon musk said they plan to do in the future, if it passes a | :02:29. | :02:33. | |
battery of tests. But what if you didn't care if your spacecraft | :02:34. | :02:39. | |
broke? Well, that is the driving force behind an idea recently backed | :02:40. | :02:44. | |
by a host of very smart mines, including Mr Mark Zuckerberg and | :02:45. | :02:48. | |
Professor Stephen Hawking. It is called the Star shop project, and | :02:49. | :02:55. | |
the plan is to launch thousands of tiny spacecraft that are little more | :02:56. | :02:59. | |
than circuit boards. If one of them breaks, that is fine, there are | :03:00. | :03:02. | |
plenty of others that can still do the job. Even better, the hope is | :03:03. | :03:07. | |
that because they are each so tiny, we can propel them to extraordinary | :03:08. | :03:11. | |
speeds, possibly as fast as a quarter of the speed of light. That | :03:12. | :03:15. | |
is more than a thousand times faster than the fastest spacecraft there | :03:16. | :03:21. | |
has ever been, that we know of. The universe is a big place, so if we | :03:22. | :03:27. | |
are to have any chance of understanding it it may be that | :03:28. | :03:31. | |
swarms of miniature craft like these are the only realistic way to do | :03:32. | :03:36. | |
it. But before the swarm can set sail there is still plenty of | :03:37. | :03:43. | |
research to be done. One sort of diminutive spacecraft we have talked | :03:44. | :03:48. | |
about before our each as big as a feast. LJ Rich has been to is Urich | :03:49. | :03:53. | |
to find out how research could make them even cheaper. | :03:54. | :03:59. | |
The recent manufacture of cheap electronic components has made | :04:00. | :04:05. | |
high-speed travel much more viable. ETH Zurich is building a system to | :04:06. | :04:15. | |
observe the ocean's surface, using cheap mobile phone chips. The first | :04:16. | :04:20. | |
will be launched in 2017, and eventually a whole grid of these | :04:21. | :04:27. | |
cubes will circle the earth. One doesn't | :04:28. | :04:29. | |
But one doesn't simply fire cheapo components up into space | :04:30. | :04:31. | |
This lab tests all kinds of equipment for space worthiness. | :04:32. | :04:35. | |
There are tanks and dials and bargain components everywhere. | :04:36. | :04:37. | |
This is how you can tell it is a working lab, and not just | :04:38. | :04:41. | |
The equipment is literally tied to the area where you most need it, | :04:42. | :04:48. | |
in case somebody walks off with the screwdriver. | :04:49. | :04:50. | |
Each of these containers contain a little bit of space. | :04:51. | :04:53. | |
OK, here on earth we can't get rid of the gravity. | :04:54. | :05:01. | |
But we can make vacuum chambers by sucking most of the air out | :05:02. | :05:06. | |
We can make things very hot, then very cold inside a container. | :05:07. | :05:19. | |
Unsurprisingly, electronics really hate that sort of thing, | :05:20. | :05:21. | |
so this is why lab techs try to break them before they launch them. | :05:22. | :05:24. | |
We chose these ones because they have a really, really | :05:25. | :05:29. | |
low power consumption, so it is, like, less than two watts we have | :05:30. | :05:33. | |
for the whole satellite, and for this we can only use 200 milliwatts, | :05:34. | :05:36. | |
When one component fails, the next one simply takes over. | :05:37. | :05:46. | |
This is a one-to-one model of the cube sat that will eventually | :05:47. | :05:49. | |
It has ten GPS chips on there, diagnostics, equipment, | :05:50. | :05:53. | |
The outsides will be mainly covered in solar panels, | :05:54. | :05:57. | |
and there will be antennas that will spring out once it is launched. | :05:58. | :06:02. | |
And of course, once this thing is launched, that is | :06:03. | :06:04. | |
This model of a Galileo global positioning satellite is what | :06:05. | :06:14. | |
Ten of these are operational right now but it takes a lot | :06:15. | :06:19. | |
This small satellite cannot fly on the rocket on its own. | :06:20. | :06:27. | |
These are some 80 million euros or so. | :06:28. | :06:38. | |
The professor's made a model cube sat on the same scale at the Galileo | :06:39. | :06:42. | |
satellite model to help us get our heads round the size difference. | :06:43. | :06:44. | |
I bet he's glad he didn't have to carry the big one! | :06:45. | :06:48. | |
Observation satellites, or navigation satellites, also need | :06:49. | :06:49. | |
a precise position and orbit, so we try to show that on the smallest | :06:50. | :06:53. | |
satellite available we can really get a position on the level of one | :06:54. | :06:56. | |
to two metres, with equipment that is low cost, very cheap, not using | :06:57. | :06:59. | |
Most tech trends show components getting cheaper or more | :07:00. | :07:12. | |
user-friendly, followed by more people accessing the technology. | :07:13. | :07:18. | |
It will be interesting watching legislation catch up with our | :07:19. | :07:21. | |
increasing ability to put things into orbit ourselves, and if the | :07:22. | :07:23. | |
democratisation of space travel, like much tech before it, is | :07:24. | :07:26. | |
inevitable, perhaps we might all get to send our | :07:27. | :07:28. | |
own project into space one day, even if we can't boldly go ourselves. | :07:29. | :07:37. | |
That was LJ, and here is one man that really | :07:38. | :07:40. | |
We first met him back in 2014, when we followed his project to send 100 | :07:41. | :07:54. | |
Well, since then, he has been busy working with Imperial College | :07:55. | :08:12. | |
London, on the next wave of crowd-funded space exploration. | :08:13. | :08:14. | |
I can't ignore the fact I am leaning on an | :08:15. | :08:16. | |
Look, there is proper science on this desk. | :08:17. | :08:23. | |
Look, we have flashing stuff, we have - | :08:24. | :08:25. | |
I am afraid it is South Kensington's finest builders' sand, and I threw | :08:26. | :08:31. | |
away the genuine fake lunar dust, which was the cement, because I | :08:32. | :08:34. | |
What that is, that is our cheapskate Mars yard. | :08:35. | :08:37. | |
So we are working on a Mars lander concept. | :08:38. | :08:39. | |
So this is a mixture of thin film devices, | :08:40. | :08:42. | |
so basically a Mars weather network, so try and drop a few hundred | :08:43. | :08:45. | |
By weather stations, you are talking about a variation | :08:46. | :08:48. | |
on your pocket spacecraft idea, thin film printable circuits. | :08:49. | :08:51. | |
This would be about 20 microns thick, so that is | :08:52. | :08:55. | |
Onboard, they would have the radio, the computers, temperature sensors, | :08:56. | :09:01. | |
humidity sensors, all the bits and pieces you would have | :09:02. | :09:04. | |
Cube sats are relatively cheap to make, but you still have to put them | :09:05. | :09:13. | |
on a rocket and get them into space, but you have | :09:14. | :09:15. | |
a plan to make them up there, rather than down here, don't you. | :09:16. | :09:19. | |
So depending on where you are going, it can take from a couple | :09:20. | :09:23. | |
of years to a decade to reach another planet in the solar system | :09:24. | :09:26. | |
What we would like to do is take the spacecraft | :09:27. | :09:30. | |
printers that we currently have in the lab, put them in cube sats, | :09:31. | :09:33. | |
and you can print the spacecraft in orbit around Mars or around | :09:34. | :09:36. | |
That means if you want to design a new space mission, | :09:37. | :09:40. | |
rather than waiting for several years you can go file, print on your | :09:41. | :09:43. | |
laptop, and then a few minutes or a few hours later, out pops a new | :09:44. | :09:47. | |
You are printing spacecraft in orbit, | :09:48. | :09:50. | |
It will take a while, but we will have our first | :09:51. | :09:58. | |
prototypes flying hopefully towards the end of this year. | :09:59. | :10:01. | |
Why are we seeing so much activity round small | :10:02. | :10:06. | |
So, up until ten years ago, when you bought a launch | :10:07. | :10:12. | |
for a spacecraft, you actually designed your spacecraft go to be | :10:13. | :10:15. | |
And then along came the cube sat standard, which | :10:16. | :10:21. | |
suddenly decoupled the shape of your spacecraft from the type of rocket | :10:22. | :10:24. | |
So you can go shopping to lots of different launch providers and see | :10:25. | :10:29. | |
what is offering the best deal, who is going in the right direction. | :10:30. | :10:32. | |
I am going to play with your little Mars yard for a bit. | :10:33. | :10:40. | |
Sticking with galactic fancies, Spacex announced | :10:41. | :10:42. | |
its partnered with Nasa in a mission to Mars, which boss Elon Musk says | :10:43. | :10:46. | |
If all goes to plan, it will be the first ever interplanetary mission | :10:47. | :10:54. | |
And it was a week full of bad news for Apple and Twitter, as they | :10:55. | :11:01. | |
announced their financial results for the first quarter of this year. | :11:02. | :11:06. | |
On the other hand, it was a triumphant week | :11:07. | :11:09. | |
for Facebook as the social network tripled its profits, compared to | :11:10. | :11:12. | |
It was the week that Stanford University's Ocean One robot | :11:13. | :11:21. | |
explored a 17th century shipwreck at the bottom of the Mediterranean. | :11:22. | :11:25. | |
The humanoid sub-bot is powered by artificial intelligence and haptic | :11:26. | :11:29. | |
feedback systems, and its creators hope it will eventually be able to | :11:30. | :11:32. | |
And not to be outdone in the robot stakes, China unveiled one that | :11:33. | :11:39. | |
The self-charging anbot is a human-hunting, pain-inducing | :11:40. | :11:45. | |
droid, designed by the military's National defence University. | :11:46. | :11:51. | |
Capable of speeds of up to 11 mph, the fearsome beast intends to zap | :11:52. | :11:54. | |
citizens partaking in any lewd behaviour. | :11:55. | :12:00. | |
This week saw the release of a brand-new product by British | :12:01. | :12:14. | |
I was invited down to its HQ in advance to find out just what it | :12:15. | :12:21. | |
I had a feeling it might have something to do with air. | :12:22. | :12:26. | |
Because from innovation in the field of vacuum cleaning - | :12:27. | :12:29. | |
sucking, if you will - Dyson has moved on to blowing, with hand | :12:30. | :12:32. | |
driers and those fans with the whole load of nothing in the middle. | :12:33. | :12:38. | |
Something that still weirds me out, if I am honest. | :12:39. | :12:43. | |
Well, it turns out the next logical frontier to air is hair. | :12:44. | :12:47. | |
Welcome to Dyson's hair laboratories. | :12:48. | :12:54. | |
They have spent ?50 million on this set up. | :12:55. | :13:00. | |
And they have on site 1,010 miles of hair. | :13:01. | :13:05. | |
Not all of it from the same person, I hasten to add. | :13:06. | :13:08. | |
The result is something called the Dyson Supersonic. | :13:09. | :13:11. | |
So take a few seconds to think about what | :13:12. | :13:13. | |
Five years in development, and after a lot of work with all that | :13:14. | :13:26. | |
hair, Dyson believes its offering can overcome what it sees as the | :13:27. | :13:29. | |
Ones that I, for one, had not noticed as being problems but then | :13:30. | :13:38. | |
The Supersonic's temperatures is regulated 20 times a second, | :13:39. | :13:45. | |
which should mean your hair can't be damaged by overheating. | :13:46. | :13:48. | |
Something that cheaper models are apparently guilty of. | :13:49. | :13:52. | |
The device is said to be quieter, lighter, and crucially, | :13:53. | :13:55. | |
it claims to offer more powerful and more controlled airflow, | :13:56. | :14:00. | |
Most of these advantages come from the motor technology at its heart. | :14:01. | :14:08. | |
This is a conventional hairdryer motor, so it is big, heavy, | :14:09. | :14:11. | |
This is the new Dyson supersonic motor. | :14:12. | :14:16. | |
So it is as small as a two pence piece. | :14:17. | :14:18. | |
That is so small we have been able to put that inside the handle. | :14:19. | :14:23. | |
So it sucks in air there at the bottom. | :14:24. | :14:26. | |
Because it is small, it can be located in the handle, | :14:27. | :14:32. | |
Because it is small, it can be located in the handle, | :14:33. | :14:46. | |
That is weird, you can do that with a hairdryer. | :14:47. | :14:50. | |
What is happening, how it works, this motor generates | :14:51. | :14:52. | |
We are getting that air to blow round that channel there, and that | :14:53. | :14:57. | |
When it accelerates, it sucks in a load more air | :14:58. | :15:01. | |
On average, there is about three times more | :15:02. | :15:07. | |
airflow coming over the outside of this and through the middle. | :15:08. | :15:09. | |
That then, as they say, is the science bit, but what you really | :15:10. | :15:13. | |
want to know is does any of this make a blind bit of difference? | :15:14. | :15:16. | |
Well, meet Lily, who has kindly volunteered to get her air done, all | :15:17. | :15:19. | |
in the name of science, and George, hairdresser to the stars, with | :15:20. | :15:22. | |
Kirk Douglas, who I was very keen to talk to, about Spartacus, Ulysses, | :15:23. | :15:30. | |
He was much more interested in the hairdressing business than | :15:31. | :15:35. | |
Let me know when you are ready to dry, George. | :15:36. | :15:45. | |
Now George reckons it would normally take about 30 minutes to dry Lily's | :15:46. | :15:52. | |
hair with his normal hairdryer, so certainly long enough | :15:53. | :15:55. | |
What is your first impressions about it? | :15:56. | :15:58. | |
It is much lighter than a conventional hairdryer. | :15:59. | :16:00. | |
Airflow is good for what I am doing now, which is just taking most | :16:01. | :16:04. | |
It is a lot more expensive than the most expensive conventional | :16:05. | :16:19. | |
Possibly double the price, if not more, but - hey. | :16:20. | :16:30. | |
Is it worth several times the cost of a salon-quality hairdryer? | :16:31. | :16:38. | |
Yes, we all spend, I don't know, 20 or 30 minutes a day doing | :16:39. | :16:42. | |
Every morning, you use it an awful lot. | :16:43. | :16:49. | |
Beauty is very important, doing your hair so it is glossy | :16:50. | :16:52. | |
and smooth and undamaged, and done quickly, because this is | :16:53. | :16:54. | |
Yes, I believe people will pay for that. | :16:55. | :17:00. | |
Next week, we will hear more from Sir James Dyson and his lovely hair. | :17:01. | :17:19. | |
Last week, the broadcast industry gathered in Las Vegas for NAB | :17:20. | :17:22. | |
On show there were loads of 4k cameras, loads of VR cameras, | :17:23. | :17:40. | |
loads of high dynamic range cameras, as you would expect, | :17:41. | :17:42. | |
but there was one piece of kit there that really did stand out. | :17:43. | :17:46. | |
We think it could change the way that films are made in the future. | :17:47. | :17:49. | |
A camera from a start up called LightO, which housed some quite | :17:50. | :17:56. | |
Instead of taking a flat 2-D image, it captured a scene | :17:57. | :17:59. | |
You could change the focus after you had taken the shot or | :18:00. | :18:10. | |
It did this by taking in so-called light rays on the sensor | :18:11. | :18:14. | |
Clever as it was, LightO's consumer camera and subsequent | :18:15. | :18:17. | |
Proving too pricey to tempt shutter bugs away | :18:18. | :18:23. | |
Well, now from the ashes a new Phoenix has arisen. | :18:24. | :18:38. | |
A beast of a camera, giving movie makers a new palette | :18:39. | :18:41. | |
LightO Cinema, capturing a staggering amount of information | :18:42. | :18:45. | |
It has millions of tiny lenses inside, sucking in | :18:46. | :18:48. | |
The end result is in fact more like a 4k image, | :18:49. | :18:52. | |
using the same core light field technology as the still cameras. | :18:53. | :18:55. | |
Knowing the distance of objects or people in front of the lens means | :18:56. | :18:58. | |
they can be isolated and replaced more easily than with today's blue | :18:59. | :19:02. | |
Of course, as with the original cameras you can decide | :19:03. | :19:05. | |
where to focus the shot in the footage after you have captured it. | :19:06. | :19:10. | |
Or change the perspective on a scene. | :19:11. | :19:12. | |
But doesn't this new-found creative palette mean the director's vision | :19:13. | :19:16. | |
In fact what we do is record as meta data what the decision was | :19:17. | :19:21. | |
made on set, and that is the first thing that we render out. | :19:22. | :19:24. | |
We also record a whole lot of other aperture views, | :19:25. | :19:26. | |
which means different perspectives, and we offer up that array | :19:27. | :19:29. | |
of different perspectives in a whole range of refocus range, | :19:30. | :19:31. | |
to make your shot different from when you originally controlled it. | :19:32. | :19:40. | |
It should enable creativity in film making, rather than remove it. | :19:41. | :19:42. | |
Saying we can lock it, this is one thing, and achieving it | :19:43. | :19:46. | |
Somebody, anywhere in the path, an editor - editors do | :19:47. | :19:49. | |
fantastically important things for movies, but they are not the people | :19:50. | :19:52. | |
LightO has one eye on the next generation | :19:53. | :20:12. | |
of film-makers - those producing content in virtual reality. | :20:13. | :20:14. | |
It has developed a light field VR rig called the Merge. | :20:15. | :20:16. | |
Content made with this camera would let you move around live action VR | :20:17. | :20:20. | |
environments, something impossible today, where you are rooted to | :20:21. | :20:22. | |
This kind of so-called computational imaging | :20:23. | :20:24. | |
technology might be compelling, but of course, it is not cheap. | :20:25. | :20:27. | |
Renting the cinema rig starts at $125,000. | :20:28. | :20:29. | |
Right now, it is aimed at the pros, but who knows, | :20:30. | :20:31. | |
a few years down the road we may see it re-emerge as a creative tool | :20:32. | :20:35. | |
Now, summer is on the way, and that means | :20:36. | :20:47. | |
if you a biker it is time to dust off the leathers and hit the road. | :20:48. | :20:51. | |
It can be exhilarating if you are of that persuasion, | :20:52. | :20:53. | |
but it can also be a long and lonely road if you have an accident. | :20:54. | :20:57. | |
It could take a while before the emergency services are | :20:58. | :21:00. | |
Well, Kate Russell has been for a spin with a piece of tech that | :21:01. | :21:05. | |
could speed up the response time and potentially save lives. | :21:06. | :21:07. | |
Just you, the road and 1200cc of pure power. | :21:08. | :21:22. | |
A motorbike isn't just a vehicle to move you from place to place. | :21:23. | :21:25. | |
It is an adventure every time you ride it, and wide-open spaces, | :21:26. | :21:28. | |
with sweeping curves and corners like this, bring body and bike | :21:29. | :21:31. | |
It is hard to beat once you have experienced it. | :21:32. | :21:44. | |
70% of all accidents on bikes happen on rural roads. | :21:45. | :21:48. | |
If you are on your own, that could be a real problem. | :21:49. | :21:54. | |
If you are out by yourself - I mean we ride together quite a lot, if you | :21:55. | :21:58. | |
are out by yourself, if you fall off, we have technology that tells | :21:59. | :22:01. | |
the emergency services where you are and sends medical information. | :22:02. | :22:07. | |
It is about keeping riders safe but still having fun. | :22:08. | :22:09. | |
To ensure pinpoint accuracy during a crash, | :22:10. | :22:11. | |
the app using downstream satellite data to locate a fallen rider. | :22:12. | :22:15. | |
If you are in an open space, where there is no blockages to the | :22:16. | :22:19. | |
signal, then you can be located down to a metre accuracy very reliably. | :22:20. | :22:22. | |
The really good news is there are more satellites going up every day, | :22:23. | :22:25. | |
including the European Galileo system, | :22:26. | :22:26. | |
which means the more satellites, the better quality signals, and that | :22:27. | :22:29. | |
accuracy is coming down to sub-metre level in the years to come. | :22:30. | :22:37. | |
We are protecting against the worst case scenario, when you | :22:38. | :22:40. | |
If you hit something, you are carrying a lot of speed. | :22:41. | :22:46. | |
They knew roughly the route he was taking, but not exactly. | :22:47. | :22:53. | |
And it was 12 hours before they found him. | :22:54. | :22:56. | |
But the bike could also be, you know, over a hedgerow or | :22:57. | :23:06. | |
You might not be visible from the road. | :23:07. | :23:10. | |
The alert is triggered by the smartphone app, | :23:11. | :23:12. | |
which is then connected through to BT, like any other 999 call. | :23:13. | :23:15. | |
That is presented to our 999 call handlers, with some enhanced data. | :23:16. | :23:18. | |
Call handlers continues with triage, by attempting to call | :23:19. | :23:20. | |
If they are unable to get in contact with the patient, then | :23:21. | :23:25. | |
It is the first app in the UK to gain DCMS certification, allowing | :23:26. | :23:29. | |
it to route activation directly through the emergency services. | :23:30. | :23:31. | |
Giving riders peace of mind that, should the worst case scenario come | :23:32. | :23:34. | |
to pass, they have the best possible chance of surviving. | :23:35. | :23:47. | |
That was Kate, and that is it from Dyson's HQ. | :23:48. | :23:51. | |
If you are wondering what this is, this is what the engineers got | :23:52. | :23:57. | |
I would be rather annoyed if they did this to my car. | :23:58. | :24:04. | |
That is from us, @BBCClick on Twitter throughout the week, please. | :24:05. | :24:08. |
