Wouldn't it be nice if someone was It you are always watching shadows,

:00:35.:00:39.

this week, Click can help. We're looking at the technology designed

:00:39.:00:44.

to keep you safe and let your family know what you are.

:00:44.:00:48.

Taking a stroll through the corridors of power. We check out

:00:48.:00:52.

the technology that captures wasted energy.

:00:52.:00:56.

We are in Dallas to take a big view of TV.

:00:56.:01:00.

All of that and the very latest tech news and the best of the word

:01:00.:01:08.

in Webscape. -- the best of the Web. When it comes to your personal

:01:08.:01:13.

safety, you can't be too careful. While our smartphones and other

:01:13.:01:19.

portable devices can't do karate, they can allow our loved ones to

:01:19.:01:24.

keep track of us. We have been finding out just how safe the

:01:24.:01:31.

latest safety tech really is. Our phones can locate where we are,

:01:31.:01:38.

take pictures, make alarm sounds and contact our friends and family.

:01:38.:01:41.

The development of apps that makes these talents should in theory

:01:41.:01:48.

provide the perfect security device. It will find way you are by

:01:48.:01:55.

combining GPS phone networks and Wi-Fi locators, then the app can

:01:55.:01:59.

communicate with your chosen contacts or a dedicated Monitoring

:01:59.:02:07.

Centre in the event of an alarm being raised. BSafe's app has been

:02:07.:02:11.

downloaded almost 100,000 times. If you sign up to a monitoring contact

:02:11.:02:15.

at the start -- contract, it will contact your loved ones with your

:02:15.:02:20.

location. The monitoring contracts are quite a cheap and simple,

:02:20.:02:26.

starting at just a few pounds per month. PanicGuard is the first to

:02:26.:02:32.

be approved by UK police. As well as providing tracking, emergency

:02:32.:02:36.

contacts and is at Inst -- emergency contact Barden, it

:02:36.:02:43.

triggers your phone's flash to shine bright and it will trigger

:02:43.:02:47.

your phone's camera. But what if you can't raise the alarm yourself

:02:47.:02:54.

in an emergency? StaySafe gets around this problem by expecting

:02:54.:02:58.

you to check into the places you're meant to be. If you have not

:02:58.:03:08.
:03:08.:03:09.

checked in, your emergency contacts will be notified. As an employer,

:03:09.:03:14.

we have an obligation to the safety of our workers and became up at

:03:14.:03:18.

this as a solution to make sure we can follow them and make sure they

:03:18.:03:21.

are OK while there are at work. Their reaction has been fantastic

:03:21.:03:25.

because it demonstrates we are a caring employer who is looking out

:03:25.:03:29.

for them. Some fear that employees could just feel they are being

:03:29.:03:33.

watched for the wrong reasons. with your right restrictions and

:03:33.:03:38.

oversight, they can be a valid way of ensuring safety, but there is a

:03:38.:03:43.

huge potential for abuse and an employee could very easily feel

:03:43.:03:46.

their employer is collecting information outside working hours,

:03:46.:03:50.

that their employer does not trust them, or that they are being spied

:03:50.:03:57.

upon. Some people will worry that their location details could be

:03:57.:04:07.

hacked into. Despite the use of secure servers by these services.

:04:07.:04:11.

Sometimes, we feel our most vulnerable at night. It is dark,

:04:11.:04:15.

you don't know who was behind to, and flicking through your phone to

:04:15.:04:19.

find the alarm button may not be a deal. He may prefer to have

:04:19.:04:23.

something closer to hand. There is no shortage of hardware to keep

:04:23.:04:29.

track their movements either. This bracelet will cost nearly 180 quid

:04:29.:04:33.

but aims to look like a simple fashion accessory. It has a built

in panic button at debated by pulling at the bracelet and it

:04:37.:04:45.

sinks while Leslie with your phone. -- while asleep. This key fob is a

:04:45.:04:50.

GPS device that can track location and act as a panic button. When it

:04:50.:04:56.

comes to be sure your kids are, brightly-coloured devices like this

:04:56.:05:00.

watch offer dedicated extras like safe zones, areas your child should

:05:00.:05:05.

stay with him, causing an alert should they go outside of them or

:05:05.:05:13.

if the water is removed. While all these devices aim to be foolproof,

:05:13.:05:18.

there is still the question of false alarms. One way to send your

:05:18.:05:24.

friends and family into total panic or seemed like you're crying wolf.

:05:24.:05:34.

Can a piece of tech be the best method of self-defence? If you're

:05:34.:05:37.

worried about being attacked in the street, you could do with something

:05:37.:05:42.

instead. On sounds on your phone are unlikely to reach the

:05:42.:05:46.

aggressive tricks of some conventional personal safety alarms.

:05:46.:05:52.

Nor spray anything in the face of the regressive. You need to think

:05:52.:05:57.

about what happens when you press that button. As the person on the

:05:57.:06:00.

other end Nate you are out? Do they know what to do when you press the

:06:00.:06:05.

button? What happens if the lease back to power? What happens if you

:06:05.:06:09.

are separated from your phone? The device is only tracking your phone

:06:09.:06:15.

and not you. While some devices may make us feel safer, when it comes

:06:15.:06:19.

to using apps, the one thing that should be protecting us is probably

:06:19.:06:29.
:06:29.:06:33.

the most valuable thing we have on A look at this week's tech news.

:06:33.:06:38.

An anti-virus Burma once of what its expense -- suspects is an

orchestrated attacks by a nation state. Kaspersky Lab says that the

:06:45.:06:49.

virus is one of the most complex threats ever discovered. It is told

:06:50.:06:54.

the BBC that it believes that the malware which steals confidential

:06:54.:06:59.

information has been active since 2010. The company thinks the tax

may have been state-sponsored but can't be sure. -- the attacks.

:07:05.:07:09.

Samsung has admitted it is facing manufacturing issues are the people

:07:09.:07:15.

-- blue models of the Galaxy S III. Customers are facing weeks of

:07:15.:07:19.

delays. The company said the plume models require a new finishing

:07:19.:07:25.

process that is taking longer to produce than first thought. All

:07:25.:07:31.

variants of the smartphone were supposed to be in the shops in 28

:07:31.:07:34.

European and Middle Eastern countries last month.

:07:34.:07:37.

PayPal is bringing its online shopping business to the high

:07:37.:07:43.

street. The company says its UK customers will be able to use an

:07:43.:07:47.

apt to pay in selected shops. Customers will have to create a

:07:47.:07:51.

PayPal account with a security pen for the app.

:07:52.:07:55.

This track and these three cars have carried out the first test of

:07:55.:07:59.

a convoy of self- driven vehicles on public roads in Europe. The

:07:59.:08:06.

convoy completed the 200 km journey on a Spanish motorway using a

:08:06.:08:09.

wireless standard developed for the calls and a number of Sciences

IndyCars. The cars themselves are being driven by software while the

:08:18.:08:21.

truck had a human driver. They accelerated, brake and toned just

:08:22.:08:26.

as the truck it. This project comes a few weeks after Google got a

:08:26.:08:29.

mission in the US to test its autonomous, on public roads in

Nevada. -- autonomous car. Most tech has been shrinking but

:08:39.:08:45.

TV's have gone the other way. It is not uncommon to see a 50 in TV

:08:45.:08:51.

these days. In Dallas, they have something which would dwarf

:08:51.:09:01.
:09:01.:09:03.

anything you could imagine. This is the largest suspended HDTV

:09:03.:09:09.

in the wild, and its home is the Cowboys stadium in Arlington Texas

:09:09.:09:14.

outside of Dallas. It can hang as low as 25 feet and as high as 120

:09:14.:09:22.

feet. With the screen, 108,000 fans can get up and put -- up close and

:09:22.:09:27.

personal with the action happening down on the field. Each of the two

:09:27.:09:32.

large screens are 40 yards wide. On the sides, there are two smaller 48

:09:32.:09:42.

feet wide screens. This screen had to be built piece by piece with

:09:42.:09:51.

four by six panels. They tried playing some 3D for the audiences

:09:51.:09:56.

but their words are receptive. With a screen this big, I can see why 2D

If he used a laptop on your actual loud, you will know these things

:10:17.:10:24.

can get pretty hot. They have a habit of running out of battery. At

:10:24.:10:31.

the thought, he took his energy. Why it -- what if he could capture

:10:31.:10:35.

the excess heat and use it to power a battery? That is the principle

:10:35.:10:39.

behind an up and coming branch of tech innovation called Energy

:10:39.:10:49.
:10:49.:11:01.

Remember your schooldays? I have quite a lot of energy at this age.

:11:01.:11:05.

Imagine if you could harness all that energy in something that was

:11:05.:11:08.

used for? That is exactly what is happening to these children's

:11:08.:11:14.

footsteps in this corridor. At this school in the Kentish countryside,

:11:14.:11:18.

they are travelling a system of flexible paving slabs that collect

:11:18.:11:23.

kinetic energy from each tart's footsteps, turning it into an

:11:23.:11:28.

electrical charge used to light up a pulp. When the stand on the tile,

:11:28.:11:34.

it flexes five millimetres in the centre. We convert that to

:11:34.:11:39.

electrical power. Seven watts per footstep is created. The heavier

:11:39.:11:45.

you are, the more energy is created. This installation is only four

:11:45.:11:49.

tiles and has been set up to demonstrate the efficacy of the

:11:49.:11:54.

system. It also shows how tough they are. We have a lower than

:11:54.:12:00.

hundred students in the school. That is about as robust as you get.

:12:00.:12:04.

If we put something like this in London Underground stations, that

:12:04.:12:10.

would be very exciting. It is easy to see the potential. What more

:12:10.:12:14.

corporations and public bodies needing to beat Green emissions

:12:14.:12:20.

targets, it could play an important part in the sustainable energy mix.

:12:20.:12:26.

One of the key sites we're working on it is at Westfield. This is the

:12:26.:12:30.

largest ever shopping centre in Europe. We will see 40 million

:12:31.:12:35.

people walking to this area of the Olympics. With that amount of

:12:35.:12:38.

football -- would fall, we will be able to power a large proportion of

:12:38.:12:42.

the lighting within the shopping centre. We weren't allowed to look

:12:42.:12:47.

inside the system, such is the fierce competition in this sector.

:12:47.:12:50.

Small companies are worried their ideas will be copied if they reveal

:12:50.:12:54.

all. But kinetic energy is typically collected using an

:12:54.:12:58.

electromagnetic system, which creates a coloured by moving a

:12:58.:13:03.

magnet inside a Coyle. It is a process that has been widely used

:13:03.:13:10.

in self- winding wrist watches for years. Other systems collect heat.

:13:10.:13:15.

This land can power a radio. Or crystals that make electric

:13:15.:13:22.

currents when under any kind of stress. And well and gas refinery

:13:22.:13:29.

plant, we have many k am of pipework and these motors and pumps

:13:29.:13:37.

fail. 1 One Wales, someone has developed a sensor which is powered

:13:37.:13:47.
:13:47.:13:49.

by vibration. When a change of sound occurs, that sense of squirts

:13:49.:13:55.

:13:55.:14:03.

needs replacing. The motor industry is using self powered senses that

:14:03.:14:08.

tore Wireless lead to the on-board computer. No wiring to add to the

:14:08.:14:14.

weight of the car, improving efficiency. Energy harvesting is

:14:14.:14:19.

sparking the imagination of inventors across the globe. Like

:14:19.:14:23.

this Kenyan entrepreneur who wants to power your mobile phone with a

:14:23.:14:27.

pad in the heel of your ship. Researchers at Cornell University

:14:27.:14:34.

believe a tree with thousands of lapping leaves may one day replace

the when deter crime. Before we get carried away, a word of caution

:14:41.:14:43.

from the organisation who would like to establish a Europe-wide

:14:43.:14:48.

standard for measuring this technology. Many people would love

:14:48.:14:58.

to see energy harvesting being used in consumer devices. The current

:14:58.:15:02.

technology at the size and scale you need it to be at can't deliver

:15:03.:15:09.

Watts of power. It is delivering 1,000 times less than is required.

:15:09.:15:14.

A really good example of how energy harvesting can be used in a

:15:14.:15:18.

consumer environment is to extend the life of batteries. Your mobile

:15:18.:15:24.

phone will last three days between charges rather than one.

:15:24.:15:29.

average person will walk 150 million steps in their lifetime. In

:15:29.:15:33.

theory, using the slabs, that is enough to power the average family

:15:34.:15:40.

home for three weeks. Imagine how many Christmas trees you could

:15:40.:15:50.
:15:50.:15:52.

Whether or not you get the point of Twitter, you cannot deny that it is

:15:52.:15:59.

a force to be reckoned with. 140 million active users are tweaking

:15:59.:16:04.

some 340 million comments every day. -- tweeting. That is the equivalent

:16:04.:16:11.

of reading around 79,000 good novels. Who has time to keep up

:16:11.:16:18.

with all of that chapter? You-know- who and she is coming up now with

:16:18.:16:23.

Webscape. Here is Kate Russell. Instead of checking out my Twitter

:16:23.:16:27.

timeline when I am supposed to be working, I found a better way to

:16:27.:16:33.

keep up with it - the social Radio 4 Twitter app. Link it to your

:16:33.:16:38.

account and then get on with your life. Soothing electronic voices do

:16:38.:16:48.

all the hard work. -- The Social Radio 4 Twitter. The Act dials into

:16:48.:16:51.

your Twitter feet at various intervals, reading anything that

:16:51.:16:59.

came in since you last checked. But to turn it off -- but turn it off

:17:25.:17:32.

-- the ultimate. It might shock you to learn that according to the

:17:32.:17:36.

Environment Agency, one in six homes in England is at risk of

:17:36.:17:44.

flooding. If you live in one of them, you is a Facebook app that

:17:44.:17:48.

could help you stay ahead of the weather. Flood Alerts kelpie said

an area of interest. This could be your home or we'll grandparents

:17:52.:17:58.

live and keep you informed of any flood warnings using live data

:17:58.:18:03.

provided by the UK Environment Agency. It seems odd to be talking

:18:03.:18:07.

about flooding when many parts of the UK have been in official

:18:07.:18:11.

drought status. But heavy rain represents one of the biggest risks

:18:11.:18:15.

of flooding because the hardened soil is not capable of draining

:18:15.:18:21.

away the water during a sudden downpour. The app will not stop the

:18:21.:18:27.

tide coming but forewarned is forearmed, as they say. Once it is

:18:27.:18:31.

running, it will post any flood warnings on your wall which you can

:18:31.:18:35.

share with the people you know, making you the modern-day hero. The
