    Electronic money

    Weve used home computers and the Internet for banking

    since the 1990s. Is the mobile wallet going to replace cash?

    Its now possible to pay or things in a shop by standing near the till and tappingan app on your mobile phone. Wave-and-pay technology allows electronic

    devices to communicate when they are near each other. Shoppers can add

    money to their phones electronically, and shopkeepers devices can take money

    in exchange or goods. Soon, some experts say, all mobile phones will have this

    technology.

    Imagine the convenience. Most o us carry a mobile phone, and with electronic

    money, we would never worry about having enough cash. We could top up the

    phones wallet online, rom a bank account, and never think about having the

    correct change or the bus. Using the phones soware, parents could give their

    kids money that could be spent only on certain things books and pencils, or

    example, but not sweets or so drinks.But dont give up on cash yet. Very ew phones have the wave-and-pay

    computer chip, and most shops dont have wave-and-pay readers. Security is

    also an issue. Some experts warn that thieves may be able to steal your money

    simply by standing near you. Wave-and-pay doesnt always use a personal

    identifcation number (PIN). A hidden reader in a thie s pocket might be able

    to take your money without you knowing.

    We wont give up cash this year or next, but some experts believe that by 2030,

    all money will be electronic.

    The pays not bad and there are opportunities or overtimei you want.

    Planning the job, especially in older buildings. Its importantto work out the best routes or the pipes, ducts, and cablesinvolved as this can aect the cost o the work

    considerably.

    I like being out and about, not stuck in an ofice, and this

    job involves a lot o travelling. I also like the contact withcustomers.

    I work or a company which installs central heating and air-conditioning systems. We do everything: planning,

    installing, testing, and commissioning.

    Get the highest qualifications you can when youre at

    college. Its better to do it at that stage in lie than try tocatch up later. Keep up your proessional training whenyoure in the job. Move to a company large enough to oer

    good promotion prospects.

    When you switch on and it all works perectly.

    Working in confined spaces, or example under loors or in

    roo spaces where there isnt a lot o headroom.

    How bioengineers apply biology, physics, chemistry, and

    mathematics to real-world problems

    Biological engineering (usually shortened to bioengineering) is the practice o

    working with, and sometimes changing, the natural world. But what does that

    mean? Here are some projects bioengineers are working on today.

    Smart medicineWe usually take medicine ater

    we realize were ill. Bioengineers

    are working on tiny intelligent

    capsules (small containers) that can

    be placed inside the human body.

    At the rst sign o illness usually a

    small chemical change a capsule

    could release drugs into the human

    body and ght the illness. At the

    moment, this is very specialized

    technology or astronauts. But

    one day, smart medicine may be

    available to everyone.

    Carbon captureClimate change is a big issue, and most experts agree that carbon dioxide

    (CO2) in the atmosphere is a major problem. While governments argue

    about the best ways to control CO2 production, bioengineers are working

    on technological solutions. One solution is to remove CO2 rom emissions as

    theyre being produced by cars and actories. This could be done by mixing the

    CO2 with other chemicals. Another possibility is to create huge carbon capture

    stations. They would look like nuclear power plants, but they would remove

    large amounts o CO2 rom the surrounding air.

    Super wheat

    The worlds population has reached seven billion people and is still growing.Agriculture growing plants and animals to eed people requires huge

    amounts o land, water, and other resources. Experts believe that as the

    population grows, it will become more dicult to eed everyone. Bioengineers

    are working on ways to improve basic ood plants such as wheat. How? They

    believe they can improve the eciency o photosynthesis the process o

    plants turning the Suns energy into ood or the plant. This increases the grain

    yield the amount o edible wheat produced without increasing the area

    o land needed. I they can do this, armers will be able to provide more ood

    without using more resources.

    Graphene a miracle material

    Graphite has been used

    in pencils or hundreds

    o years. But could it be

    the source o the next big

    breakthrough in materials

    science?

    Graphite is made entirely o carbon atoms just as diamonds are. In

    diamonds, the atoms are arranged in a crystal structure that makes the

    material incredibly hard the hardest substance in the world. By contrast,

    carbon atoms in graphite are arranged in at layers. This makes graphite

    relatively sot. It also means that graphite can orm very thin layers, such

    as when you make a mark on paper with a pencil.

    Hanns-Peter Boehm, a German chemist, frst observed layers o graphite

    that were only one-atom thick in the 1960s. He named his discovery

    graphene. Other scientists studied and tried to produce graphene

    throughout the 1970s, 80s, 90s, and into the 2000s. A breakthrough fnally

    came in 2004, when two physicists at Manchester University removed a

    single-atom-thick layer o graphene rom a piece o graphite using a

    piece o ordinary sticky tape. They received a Nobel Prize or their work.

    Whats so great about graphene?

    Graphene sheets are 200 times harder than steel.

    Graphene conducts electricity better than silicon.

    Its extremely thin and lightweight.

    What will we do with it? Here are some o the experts ideas:

    Graphene could be used to replace silicon in computers logic circuits.

    Incredibly strong abrics or smart clothing could be made with

    graphene.

    Screens o gadgets such as smartphones could be made much stronger

    with graphene.

    What can you do with adegree in Mathematics?

    You probably know about accounting and teaching, but

    here are some maths jobs you may not have heard of

    Computer securityComputers are everywhere, and they

    contain our bank account inormation,

    credit card details, medical records,

    and other data we want to keep secret.

    How can we keep hackers rom stealing

    this data? Cryptography is a feld omathematics that involves writing codes

    and fnding ways to keep secrets. Governments and private companies

    employ cryptographers to keep computer data sae and secure.

    Atmospheric science and meteorologyGlobal warming has become a big concern. Scientists use mathematical

    models to help them understand how the Earths complex environment

    systems might behave in the uture. Meteorologists (weather experts) also

    use mathematical models when theyre predicting the weather or the next

    weekend or trying to understand what huge storm systems might do next.

    BiomathematicsDoctors and medical researchers rely on experiments and observationto understand medication. They also use complex mathematics to

    understand drug data and to predict possible responses to medicines.

    Biomathematicians also apply mathematics to the understanding o the

    interaction o living things in biological systems.

    Business analysisBusinesses usually want to improve their efciency. But particularly in

    larger, more complicated businesses, it isnt always easy to understand

    how systems really work. Mathematical analysis can be applied to many

    aspects o business (production processes, transportation and storage o

    products, worker efciency) to help identiy places where improvementscan be made.

    Petroleum productionFrom exploration to transport, use and environmental impact,

    mathematics is an incredibly useul tool in the energy industry. In

    addition to understanding the fnancial side o the business, mathematics

    is used by geologists (experts in rocks, soil, and other eatures o land)

    to predict where oil might be located, how much there is, and how long

    it will last. Mathematics is also used to predict what may happen as oil

    becomes more difcult to fnd.

    Smart cities

    By 2050, 70 per cent of the worlds

    population will live in cities. Experts

    say that we need to make the best

    use of technology to make these cities

    good places to live. So fast forward

    to 2050, and what do we see?

    Green roosMost buildings in the smart city o 2050 have plants on the roo. Plants help

    keep the air clean, and they reduce ooding problems when heavy rainalls. They also absorb heat, which keeps cities in warm climates cooler.

    Some people grow ruit and vegetables or themselves, too.

    Grey waterThe smart city o 2050 wastes nothing. Rainwater is collected and used

    on gardens. Grey water water rom showers and rom washing up is

    recycled or rootop plants and is also used or ushing toilets. Puriying

    water uses a lot o energy, so using grey water saves both water and energy.

    Clever waste managementThere are no lorries collecting rubbish in the smart city. This helps reduce

    trafc on the roads. All waste travels rom homes and businesses in a

    system o pressurised pipes. Some o the waste is used to produce methanegas, which is used or energy production.

    Green powerIn addition to the power generated using methane gas, wind and solar

    generation also powers the smart city. Computers monitor power use in the

    entire city and the electric power grid can respond to the need or power at

    any moment. When a lot o power is needed, the system can supply it, but

    when little power is needed, parts o the system shut down. This reduces

    energy waste.

    Intelligent trafc managementEvery car in the smart city o 2050 has a smart

    tag number plate. Sensors in the road track everyvehicle and control the ow o trafc. I a road is

    completely empty, the trafc signals are turned o

    to conserve energy.

    Smart homesResearch shows that when people can see how

    much energy theyre using, they limit their energy

    use. The smart home o 2050 has an energy control

    panel. People can monitor their energy use and

    control heating and lighting.

    Designing or perormance:

    A high-altitude safety suitHow astronauts, pilots, and space tourists dress for success

    In 1960, US Air Force pilot Joe Kittinger

    used a balloon to travel more than 31

    kilometres above the surace o the Earth.

    From that altitude, he jumped and ell or

    our and a hal minutes, reaching a speed

    o 988 kilometres per hour beore opening

    his parachute at 5,500 metres above the

    Earth. In one day, he set the record or the

    highest balloon ight, highest parachute

    jump, longest ree all, and astest human

    all. As humans were approaching the

    possibility o space ight (the frst spaceight was on 12 April 1961) aerospace

    doctors wanted to understand the eects o

    very high altitudes on the human body, and

    wanted to know i people could jump out o

    spacecrat high in the Earths atmosphere

    in case o emergency. Amazingly, Kittingers

    record wasnt broken until 14 October

    2012, when an Austrian skydiver, Felix

    Baumgartner, made a 39,045 metre jump.

    What are the design challenges o making

    a suit that can survive a all rom the edgeo space?

    PressureIn the stratosphere the part o the

    atmosphere where Kittinger began his all

    the air pressure is about 1/1,000th o the

    pressure at sea level and contains very little

    air. To avoid altitude sickness, the saety suit

    must have a pressure inside that is similar

    to the pressure nearer the Earths surace.

    The suit is tightly sealed, and special

    containers o gas are used to maintain a

    comortable pressure.

    Oxygen supplyThe suit has two tanks o 100% oxygen (not

    air, which is about 78% nitrogen). Breathing

    pure oxygen removes nitrogen gas rom

    the skydivers body. This is because during

    changes in pressure, nitrogen bubbles in the

    body can cause serious medical problems.

    Temperature controlThe temperature outside the suit is between

    68 C and 38 C. The suit is made o a

    super-insulating material that keeps the

    inside o the suit comortable even as the

    outside temperature changes rapidly.

    ParachuteThe main parachute opens automatically,

    at about 750 metres above the Earth. A

    sensor detects the atmospheric pressure at

    that altitude. This means that i the skydiveris injured or unconscious, a sae landing is

    still possible.

    CommunicationsIn addition to a two-way radio, the suit

    includes instruments that measure the

    skydivers breathing, heart rate, speed, and

    angle o the body as it alls. The suit also

    includes a video camera.

    Hh-tch sprtswrSports companies are always trying to develop newsportswear that will allow athletes to perform moreefficiently. Recent developments include:

    PReCool veST

    Nike has developed a vest which holds ice packs in its lining. It is designed

    for athletes who compete in marathons and other long distance races.

    Wearing it for one hour before the race will reduce the body temperature

    by %, and therefore reduces the risk of heat injury.

    faSTSkin

    Speedo has designed a swimsuit which it claims is the worlds fastest. The

    designers have worked with an expert on sharks famously fast swimmers

    of the fish world. The material copies features of Sharkskin and is designed

    to reduce drag. The makers say it can increase performance by up to %.PoWeR SoCkS

    Adidas produces knee-length socks for runners which are designed to

    reduce leg fatigue. The socks save energy by compressing the muscles in

    the legs. This prevents the muscles vibrating each time the runners foot

    hits the ground. The vibration is a waste of energy.

    SWifT SuiT

    Adidas has designed an aerodynamic

    head-to-ankle suit for sprinters, cyclists,

    rowers, and ice-skaters. It keeps athletes

    cool and reduces drag. The designer

    claims it gives a ten-centimetreadvantage in a -metre sprint.

    STRaPleSS goggleSFor swimmers, Nike has developed featherweight carbon goggles without

    straps. Each lens is stuck to the eye socket with medical glue. Having no

    straps, the goggles produce less drag than ordinary goggles.

    in countries of the developing world.It has a very simple design anduses inexpensive parts. The UnitedNations estimates that ,people die each year because ofmines.

    The Dervish has three wheels. Eachwheel has steel teeth to create more

    pressure. When the teeth pass over amine, it explodes. The wheels canexplode around , mines before

    they have to be changed.A motorbike engine powers theDervish. The device rotates. As eachwheel passes a certain point in therotation, it slows down. This makesthe machine advance in tight circles,about mm apart. For this reason,no mine in its path is missed.

    The iris is the coloured ring round the central part oyour eye. Each one is dierent, which makes it perect

    or security systems such as iris scanning.

    First, your iris is scanned and the inormation converted

    to a digital file which is stored in a database. This

    process takes about three minutes. When you go to a

    high-security area, you simply look at a camera which

    scans your iris. The result is compared with your

    database entry. It takes just over a second to complete

    the check.

    The system is used at airports to speed passengers

    through passport control and to control entry torestricted areas. Some banks use it at ATM machines

    instead o PINs.

    Apart rom the speed, the advantage is that users dont

    need to remember a password or key. The system can

    handle users wearing glasses, contact lenses, and also

    changes to the eye as people age. So ar, its oolproo.

    The advanced taser gun is an electric stun gun which allows police to

    deal with violent people without causing injury or death. It has a laser

    sight to make sure the suspect is properly targeted. It uses a compressed

    air cartridge to fire two darts at the suspect. The darts pull behind them

    fine electric cable. They can penetrate the thickest clothing, up to 5

    centimetres, at a range o 6.4 metres.

    When the darts hit someone, the gun delivers a 50,000 volt shock or

    five seconds. The shock causes temporary paralysis. Taser waves

    electrical signals cause the suspects muscles to contract. The guns

    contain a microchip which records the date and time o each firing.

    system (GPS) technology to record the

    wearers movements. This data is ed

    to a server which matches movements

    with places. Some oenders are

    restricted to an area around their

    home. I they move outside that area,

    this is reported by email to the police.

    Some oenders are orbidden to enter

    certain areas. I they go there, this too

    is reported automatically to the police.

    The system also contains details o

    crimes. I an oender is near the scene

    o a crime at the time it takes place, a

    report is sent directly to the police.

    Hybrid cars

    A hybrid-electric vehicle (HEV) has both a petrol engine and anelectric motor. The petrol engine is the main power source. It issmaller and lighter than the engines o conventional cars. Theelectric motor provides extra power when needed. In some HEVs, it isconnected to the wheels by the same transmission. In addition to auel tank, the HEV carries a pack o advanced batteries. There is also a

    processor which decides when to use the motor and engine.When the car is running at a constant speed cruising the petrolengine provides all the power required. For overtaking, hill climbing,and accelerating rom a standstill, the electric motor provides extrapower. In some cars, the motor also provides power or low-speedcruising, as petrol engines are least eficient in these conditions.

    HEVs use regenerative braking. When the driver brakes, the resistanceo the motor helps to slow down the car. At the same time, the energyrom the wheels turns the motor which then unctions as a generator,producing electricity to recharge the batteries. When the batteries arelow, the petrol engine also drives the generator.

    HEVs have automatic start / shuto. The petrol engine shuts owhen the car comes to a stop. When the driver presses the accelerator,

    the motor instantly starts the engine again. No energy is wasted romidling when the car is stopped.

    HEVs are more eficient and pollute less than cars with only petrolengines. They do not require special uel like hydrogen cars and,unlike electric cars, they do not need to be plugged in overnight torecharge the batteries. However, they are heavy because o the weighto the batteries.

    The development of tall buildings and lifts go together. The first

    lifts, or elevators in American English, consisted of a platform

    suspended from a rope which passed over a pulley at the

    top of the building. If the rope broke, the platform fell to the

    ground. In 1852, Elisha Otis invented the first safety lift. If the

    rope broke, a brake was applied automatically which locked the

    platform in place between guide rails. Today the Otis company

    is the largest supplier of lifts in the world.

    Most lifts today are roped lifts. The car runs between vertical

    guide rails which keep it steady and act as a safety device. Steel

    ropes, or cables, attached to the roof of the car pass over apulley, called the drive sheave, which is turned by an electric

    motor. The other end of the cable is attached to a

    counterweight. This matches the weight of a car with an

    average load of passengers.

    The counterweight saves energy. Its weight helps to raise the

    car. In the same way, the weight of the car when it descends

    helps to raise the counterweight. For the most part, the motor

    only has to overcome friction.

    Lifts are controlled by a microprocessor in the machine room.

    This logs all passenger calls and monitors the number ofpassengers travelling from floor to floor, the position of any car

    in the system, and its speed. It can direct passengers to the car

    which will get them to their destination fastest, and will prevent

    any car which is overloaded from moving.

    Lifts have many safety devices which make it virtually impossible

    for an accident to happen. The cables consist of up to eight

    steel ropes wound together. Each one is strong enough to

    support the car. If the car starts to run too quickly, a governor,

    or safety brake, locks the car to the guide rails. Doors on each

    floor ensure that no one can fall down an open lift shaft. Doors

    on the car ensure that no passenger can be injured by contact

    with the shaft. The car cannot move until both sets of doors

    are closed. Finally, at the bottom of the shaft there are large

    shock absorbers, or buffers, to cushion the impact of any fall. All

    these things combined make travelling in a lift one of the safest

    journeys you can take!

    Touch screensWith tablets and smartphones, plastic keyboards seem a

    bit old-fashioned. So whats next for touch screens?

    Todays touch screens are made o glass. Theyre at like glass, and a bit cool like

    glass. I youre used to typing on a traditional keyboard, you may think touch screen

    typing isnt as nice. You dont eel a click when you press a key (though you can

    choose to hear one). Many people say this is a small problem compared with the

    great benefts o touch screen keyboards: theyre lightweight, easy-to-clean, and they

    disappear when you arent using them.

    Touch screens are here to stay, but researchers at a company called Tactus say that

    people like to eel things more that while touch screens are beautiul, real buttons

    are more user-riendly. These researchers are working to create tactile touch screens

    at screens that can create raised buttons that users can temporarily eel. Small

    areas o the plastic screen inate and then return to a at surace. This sort o

    screen is still probably a ew years away, but research and development teams are

    already working hard at producing it.

    The eeling o buttons may be just the beginning. Another team o researchers has

    announced a technology called REVEL that can create not only the eeling o a raised

    area, but also dierent textures, or example rough wood or smooth cloth. At the

    moment, this technology works only when the fnger is moved across the screen. In

    this case, the screen itsel doesnt change. It works by attaching a small electrical

    signal generator to a persons chair, or perhaps the inside o their shoe. When they

    touch certain objects, a small electrical signal travels through the body, and a small

    electrostatic orce is created where the fnger touches the screen. This creates the

    illusion o eeling.

    These two technologies will be useul not only in smartphones and tablets, but also in

    games, navigation equipment, and controls on electrical appliances.

    So, whats the uture o the touch screen? It turns out it may be something you can

    eel, like an old-ashioned keyboard.

    Telec mmunications

    more than just TV and telephones

    TVs and smartphones are getting smarter but

    ridges and washing machines now include computers

    and are Internet-ready

    Many o us are used to getting an

    email or a text message saying

    Please pick up some milk on the

    way home. Soon, that message may

    not come rom a riend, roommate,or spouse, but rom the ridge. How

    does the Internet-ready ridge

    work?

    Products in the smart ridge have

    radio requency identication (RFID)

    tags. These are small computer

    chips that store inormation, or

    example This is a two-litre carton

    o milk. It was manuactured on

    22 September. With a built-in RFID

    reader, the ridge knows whatsinside it at all times. You can set the

    ridge to send you an alert when theres only one carton o milk

    let. The smart ridge can also be programmed to keep a list o

    products that you need, and place an order with the supermarket

    or delivery when certain products are about to run out. An app on

    your smartphone allows you to check the contents o your ridge

    rom anywhere.

    The smart ridge also communicates with the electrical power

    company. Some companies charge diferent rates or power at

    diferent times o day. The ridge receives signals rom the power

    company when electricity rates are higher, and switches to a low-energy mode or brie periods.

    Its easy to see the benets o an Internet-ready ridge, but what

    about an Internet-ready washing machine? Korean appliance maker

    LG already produces one. I theres a problem with the machine, it

    sends you a message with a ull explanation. I you need to deal

    with particular stains in clothing, you can download a special wash

    cycle to solve the problem. The product line also includes an oven

    that can download recipes and cooking instructions, and will send

    you a message when a meal is cooked and is ready to be taken out

    o the oven.

    Telemedicine is the application of Information Technology to medical care.Its about providing medical support at a distance to people who have noaccess to a doctor. Using the Internet, satellite phones, video links, and digitalcameras, patients, nurses, doctors, and others can obtain specialist helpquickly.

    If passengers fall ill on an aircraft in flight, cabin crew can use a device calledVital Signs to measure blood pressure and other important signs. The datacan then be transmitted to a doctor to interpret and provide advice ontreatment. Medical images, such as X-rays or ultrasound scans, can be takenin one country and sent by broadband to a specialist in another for expertadvice. Using a video link, nurses in a minor injuries clinic can call a specialistto examine difficult cases remotely. This is much cheaper than having aspecialist available in the clinic.

    Telecare is a way of looking after vulnerable people, such as the elderly, at adistance. Sensors in their homes can detect falls, lack of activity, or even iffood is removed from the refrigerator. Lack of movement triggers an alarmwhich alerts medical staff or relatives. Patients can wear monitors for

    recording their pulse and other signs. This can be sent via a telephonesystem to medical staff without the patient leaving home.

    Telesurgery was used in 2001 to allow a surgeon in New York to operate ona patient in France. The operation was carried out using a high-speedcomputer link and robotic tools in the French operating theatre. At thisstage, such procedures are expensive, and a local surgeon has to be presentin case the network link fails. In the future, however, telesurgery could be alife-saver for people living, working, or travelling remote from medical help.

    Robots are very good at doing the same task in the same place over

    and over again. In factories and nuclear power stations, more than a

    million robots behave in this way every day.

    For robots to work with people, for example caring for the elderly, they

    need to be much more like humans. They need to be able to move

    like humans and adapt to new places. They also need to be more

    sensitive to touch and temperature. In humans, it is skin which provides

    important information on pressure and heat.

    Engineers at the University of Tokyo have developed an artificial skin for

    robots which is sensitive to pressure and temperature thanks to a large

    number of sensors. In addition, because it uses a mesh or net structure

    it can be stretched by up to 25% and still retain its sensitivity. This

    means it can be used to cover moving parts like joints.

    This E-skin opens the way for much more sensitive robots. For example,

    walking robots could use feedback from their feet to adjust to different

    surfaces. Robots in the future may be able to grasp different tools and

    use them as humans do. Domestic robots could pick up and bathe a

    baby without hurting it. They would also be less likely to damagethemselves.

    A lot remains to be done. E-skin will provide much more information

    than the robot requires at any one time. Human brains can select only

    the important information. Before robots can act like humans, they need

    to have brains like humans.

    What is permaculture?

    Permaculture is an approach to

    growing ood. It aims to develop

    sustainable systems o agriculture.

    What are its main objectives?

    To take care o the Earth, to takecare o the people, and to share the

    surplus the ood we grow beyond

    what we need.

    How does it meet those

    objectives?

    It aims to integrate agricultural

    systems with natural ecosystems

    as much as possible. In the world

    today, mainstream agriculture oten

    requires the transportation o water

    and ertilizers long distances to make

    plants grow. Farm produce, in turn,

    is transported long distances to the

    consumer. Permaculture uses local

    resources to grow ood or local

    consumers.

    Can you give us an example?

    Sure Jordan. Jordan is a desert

    country with very little water. The

    soil is oten poor and requires a

    lot o chemicals to grow ruits and

    vegetables. More than hal o the

    available water in Jordan goes toagriculture, but demand or water

    has increased in the past ten to

    twenty years. Its an incredibly tough

    place to grow ood.

    At one arm in Jordan Valley, in the

    Karin area near the Dead Sea,

    theyre practising permaculture.

    The rainall there is usually less than

    150 mm per year, and it alls in two

    or three big storms. The soil is poor.

    Interview:Farming the desertPermaculture expert Karim Benzid talks

    about farming in a land with no water

    So frst, lets consider water. On

    this arm, theyve set up a system

    to harvest rainwater when it does

    all. They can store the water, and

    they use it in a way that reduces

    evaporation. It is ed to the plants in

    a steady drip. They also use somewater rom a well on the arm. So

    its local ground water. The plants

    are arranged so that the ones that

    need the most water are nearest to

    the source o the water. This reduces

    waste.

    Second, plants. The arm has olive

    trees and date palms they both

    love the dry climate. These help

    shelter and protect other smaller

    plants tomatoes, onions, garlic,

    and so on rom the Sun. In act, thevariety o plants is really important. In

    this area, armers usually grow just

    one type o plant at a time.

    Which brings me to my third point,

    soil. Growing just one type o plant is

    terrible or the soil. Growing a variety

    o plants actually helps the soil.

    Also, the arm has chickens, sheep,

    ducks, and other animals. Waste

    rom the animals, plus waste rom

    the plants, is used to eed the soil.

    All o the energy and chemicals thatthe soil needs come rom this waste

    material. Theres no need to use

    chemical ertilizers.

    Finally, consumption. The ood

    grown on this arm is eaten locally.

    That means they dont use energy

    bringing some oods into the

    area, and they dont use energy

    transporting arm produce out o the

    area. Its very efcient.

    3-D printingTurning computer images into plastic modelsSince the 1990s, engineers have used

    3-D printing to make models o complex

    designs. More recently, 3-D printing has

    been used to make objects or actual use,

    not just models. For example, doctors

    have used 3-D printing to make articial

    body parts such as bones and joints. Te

    process called rapid prototyping is

    still not widely used. But its becoming

    more common and techniques are being

    improved constantly.

    And now, three-dimensional printing at home is a reality. You buy and bring

    home a 3-D printer, download a design rom the Internet, and create plastic

    objects in your own home. Heres what you do:

    1 Prepare the printer by loading it with plastic wire. Te wire comes in ten

    colours. You also have to spread glue on the print platorm.

    2 Search the Internet or designs o objects that can be 3-D printed. Printer

    manuacturer Cubiy has a wide selection at cubiy.com, and others are

    available elsewhere. Designs include toys and games, jewellery, cups,lampshades, and many other things.

    3 Using the 3-D printers soware, convert the design to a set o

    instructions or building the object. Te soware works out any special

    supports that might be needed as the object is printed.

    4 Press Print and watch the printer create your design.

    5 Let the plastic cool of, and enjoy your creation.

    So how does it work? Te printer heats the plastic wire until its so. Te

    printer tip is heated to 300 C, so when the plastic passes through it, it

    becomes even soer. Te soware tells the tip o the printer where to move

    to build up the object line-by-line. Te printer tip can move up, down, and

    sideways, so it can go anywhere the soware tells it to.

    Te 3-D printer doesnt make solid plastic objects. Instead, they are mostly

    hollow, with a kind o grid structure between the two walls o plastic. Tis

    makes the object strong and lightweight, and also reduces the amount o

    plastic needed to print it.

    Teres an important diference between 3-D printing in medicine and

    industry and 3-D printing at home: engineers and doctors use it to create

    things they really need. But or now, at least, the things you can print in plastic

    at home arent especially useul.

    This North Atlantic island is giving up ossil uelsEl Hierro, an island about 1,400 kilometres o the coast o Arica, is

    home to 11,000 people. Until recently, their energy supply relied

    on oil that arrived by ship rom the mainland. However, as energy

    prices increased, it became harder and harder or them to pay or

    the delivery o ossil uels. Lucky, then, that the island has over 3,000

    hours per year when the wind blows hard enough to turn large wind

    turbines. The islands wind turbines produce about 11 megawatts o

    power.

    But the wind doesnt always blow on El Hierro, and when the wind

    stops blowing, the electricity stops fowing. The power grid doesnt

    store electricity it needs to be constantly generated, which is one othe big challenges o wind energy. The solution? El Hierro has created

    a 500,000m3 reservoir at an altitude o 700 metres, inside the dormant

    volcano at the islands centre. That means that when the wind is slow,

    water can be allowed to fow downhill through hydroelectric turbines

    that generate the electricity the island needs. The water ends up in a

    smaller reservoir near sea level, where it is puried or drinking.

    You might imagine that the reservoir would soon drain all o its water

    downhill. But youd be wrong. When the wind is blowing and theres

    plenty o electricity available, pumps push desalinated seawater back

    up to the top o the hill, ready or the next drop in wind speed. The

    winds tend to blow the hardest at night, when people are asleep andenergy demand is low, so this is the perect time to rell the upper

    reservoir. The system generates enough electricity or two wind-ree

    days. I the wind stops or three days, theyll have a problem. But so ar,

    that hasnt happened.

    The project can generate enough energy to save the 40,000 barrels

    o oil they were importing each year, at a cost o 2 million at current

    oil prices. The system also provides drinking water and water or

    agriculture.

    can already run on some orm o

    hydrogen power. However, all o these

    are experimental vehicles.

    ChallengesHydrogen doesnt occur naturally on

    Earth it must be produced. At the

    moment, hydrogen is mostly produced by

    using methane (a powerul greenhouse

    gas) or other ossil uels, which produce

    CO2. Also, the equipment required to

    produce and saely store hydrogen is

    large and complex too big to t onmost vehicles. Researchers working on

    hydrogen power are trying to develop

    technology that will make hydrogen

    power more mobile or use in vehicles.

    Theyre also trying to nd practical ways

    to produce it without ossil uels.

    Hydrogen trainsResearchers in several countries

    have independently announced the

    development o hydrogen-powered

    trains. Trains are ideal or hydrogen uel

    cells because they have a lot o storage

    space on board, and they also stop

    routinely at stations. Station stops or

    hydrogen trains would allow requent

    reuelling. This would mean that the

    large and complex hydrogen-production

    equipment could remain in xed

    locations.

    The Fuel Cell Bus ClubThis organization is running a trial using

    three Mercedes-Benz hydrogen uel cellbuses in eleven cities around the world.

    Each bus can carry about 70 passengers

    or a range o 300 kilometres and costs

    $1.2 million. The aim o the project is

    to demonstrate that clean, urban public

    transport is possible.

    Fuel cell carsMost o the major automotive

    manuacturers are carrying out research

    into how to power cars with uel cells in

    order to ght global warming. However,

    critics say that even twenty years in

    the uture, a uel cell car may not be

    possible, and also that uel cells simply

    arent practical or smaller vehicles. Many

    believe that ghting global warming

    with uel cell car research is a waste o

    time and money.

    The road aheadHydrogen uel cells have been proven

    to be efective ways o powering larger

    vehicles. However, theres still the

    serious challenge o creating hydrogen inan environmentally riendly way. Experts

    are working on using wind, solar and

    nuclear energy or hydrogen production.

    Shale gas

    Energy solutionor environmentalnightmare?

    Fracking could solve a lot of

    energy problems, but many

    people say it isnt safe

    In April 2011, a small earthquake shook the English seaside resort of

    Blackpool. The following month, there was another. The earthquakes

    didnt do a lot of damage, but they worried people. Geologists saidthere was a direct connection between the earthquakes and nearby

    gas exploration. The exploration work was stopped for a year, but has

    since been allowed to continue.

    What is shale gas?Natural gas usually comes out of the ground under pressure it rises

    to the surface when a well is drilled. However, shale gas is different.

    Its trapped inside a type of rock known as shale, and it doesnt come

    out, even when a well is drilled directly into the shale. A technique

    called fracking is used to extract shale gas.

    What is racking?Fracking is short for hydraulic fracturing. Water under pressure is

    used to create cracks in shale the rock that contains the gas. The

    water, containing sand and a mixture of chemicals, is forced into steel

    pipes that have been placed into the ground.

    Why do we need shale gas?Because theres a lot of it. Experts believe that most countries that

    currently produce natural gas have huge reserves of shale gas. If they

    can use that shale gas, many of the worlds energy problems would be

    temporarily solved.

    Whats the problem with racking?There are three main worries. First, fracking sometimes causes

    earthquakes, and earthquakes can hurt or even kill people, as well

    as damage buildings and other property. Second, the water used in

    fracking contains chemicals, and they can leak into drinking water

    under the ground. There are hundreds of chemicals used in gas

    drilling, and many of them can cause serious health problems for

    people and animals. Finally, fracking uses a lot of water. In some

    cases, fracking has used so much water that is has affected local water

    supplies and taken water that was needed for drinking and farming.

    Despite the potential problems, fracking continues today all over the

    world, and shale gas may soon be an important part of the worlds

    energy supply.

    Can man-made volcanoes

    solve our climate problems?The Earths atmosphere the layer o air around

    the planet helps control the Earths temperature.

    CO2 in the atmosphere can cause problems

    because it allows sunlight to come through, but it

    tends to trap heat. Since the 1800s, people have

    added a lot o CO2 to the atmosphere, mostly

    through industrial activities. This is causing our

    planet to become warmer.

    Most experts agree that we should reduce

    the amount o CO2 in the air to reduce globalwarming. But some scientists think we may need

    to do more. Researchers in Britain would like to

    nd a way to cut down the sunlight that passes

    through the atmosphere. They believe that i we

    could achieve this, we could stop global warming.

    They are trying to nd a chemical that would

    reduce the amount o sunlight coming through

    the atmosphere i sprayed into the air.

    Researchers have known or years that large

    volcanic eruptions can cool the planet. The

    smoke rom volcanoes contains sulphur dioxide.

    Chemical reactions in the atmosphere change the

    sulphur dioxide into tiny particles o sulphuric

    acid. The acid particles refect the Suns radiation.

    This cools the planet. Scientists are not suggesting

    that we should spray sulphuric acid into the

    atmosphere its a strong chemical that can

    damage people, plants, animals, and property.

    However, they do want to nd a chemical that

    behaves in the same way.

    Not everyone thinks this is a good solution. I

    something unexpected happened, placing large

    amounts o chemicals into the atmosphere could

    cause serious changes in the weather or create

    other problems. Even the scientists who are

    working on the project agree that it might be too

    dangerous to try. But i global warming becomes a

    lot worse, we may have to consider it.

    The future of robots

    Three very diferent approaches to machinesthat work like living things

    The robot that eatsThe Ecobot III produces its own energy by eating unwanted human ood, such as rotten

    ruit, and also water rom the environment around it. The robot contains uel cells that

    work like a cows stomach. The cells contain bacteria that consume the ood. The

    resulting chemical reaction creates energy that powers the robot. O course, everything

    that eats also produces waste in the case o the Ecobot III, this is CO 2. However,

    scientists point out that this isnt the same as releasing CO 2 by burning ossil uels. The

    CO2 produced by the Ecobot III would have been produced by the ood biodegrading

    anyway. In experiments, the Ecobot III has managed to stay alive and eed itsel or up toseven days. It moves around slowly on small wheels.

    The robot that runsThe cheetah is the astest land animal in the world. Thats why scientists at robotics rm

    Boston Dynamics chose it as the model or their our-legged, running robot. By looking

    closely at how a cheetahs running body unctions, they were able to create a robot that

    can run. The secret is in the fexibility o the robots back. The back bends so that the

    robots back eet can move as ar orward as its chin as it sprints. This allows its eet

    to stay on the ground longer, making it ast like a real cheetah. Currently, the cheetah

    robot can move at 45 kilometres per hour. Thats impressive, but at the moment, it can run

    only on a treadmill in the laboratory, with support. It also requires a power cable to an

    outside battery. Scientists are working hard to improve the robots balance and develop anonboard power source.

    The robot that looks like a personEarlier robots like ASIMO had a human shape but moved in a mechanical way. The

    Eccerobot has a body that uses systems and structures that are similar to the human

    body: articial bones, muscles, and tendons. Where traditional robots have rigid joints and

    very mechanical movements, the Eccerobots movements are strangely human. Why? The

    robots bones are connected by rubber bands and pieces o sot rubber tissue. When the

    robot moves, motors pull on the rubber bands, which

    in turn move the bones. The movement o the bones

    causes other parts to move slightly, rather than

    creating an isolated, mechanical motion. The robotsbrain is, o course, a computer. At the moment,

    the main unction o the computer is to receive

    inormation input rom the robots body and react

    appropriately. For example, i you hand the robot a

    ball, it can gently take it rom you.

    At the moment, the Eccerobot only has an upper

    body it has no legs, and it cant move itsel. But

    as scientists perect the robots movement and

    thinking ability, it will be able to perorm more and

    more activities.

    Te secret of

    invisibilitySince ancient times, people have used

    camouage body paint or other

    coverings to hide while hunting or

    fghting. These simple techniques are still

    used today, but technology oers many

    more sophisticated ways o hiding.

    Invisible clothesWho wouldnt want an invisibility

    suit? This isnt yet possible, but

    researchers have discovered that

    they can create a type o optical

    camoufage. Heres how: the person

    who wants to disappear wears

    clothing in a solid, light colour.

    Cameras lm the area behind the

    person, and this background image

    is projected onto the ront o the

    person. When you look at the person

    rom the ront, you can see the

    background projected on the person,and they becme dicult to see.

    Hidden submarines

    Sea creatures such as the octopus

    and cuttlesh can change the colour

    o their skin to blend in with the

    background. Their skin contains

    chemicals that make this possible.

    Marine biologists are now working

    with the military to understand

    exactly how some sh can change

    colour in an attempt to gure out

    how navy submarines could be madeto do the same thing. This research is

    still in the very early stages.

    Disappearing buildings

    Architects and town planners oten

    talk about the visual impact o a

    structure will a new building

    make the city more beautiul, or will

    people complain because its ugly?

    Optical science researchers have

    discovered that some tiny crystals

    can bend and refect light. In theory,

    i you covered an entire building in

    these crystals, they could refect the

    light in such a way that the building

    would be very dicult to see. Thats

    probably not practical or city-

    centre buildings, but the military is

    denitely interested.

    Transparent people

    Brain scientists have created a

    chemical that makes brain tissue

    transparent. Researchers have made

    small pieces o mouse brain tissuecompletely see-through, which aids

    their research. Would it be possible

    to turn an entire living creature

    transparent? At the moment, were

    not even close. The chemical used

    on mouse brains is toxic, and not

    used on living creatures. However,

    scientists have already discovered a

    milder chemical that may have the

    same eect.

    Good old-ashionedcamoufage

    Technology can do a lot to help the

    military hide people and things, but

    most soldiers still use grease paint on

    their aces, camoufage clothing, and

    some leaves when they need to hide.

    Soldiers are trained to use plants

    and other natural materials to hide

    or disguise military equipment, or to

    create decoys things used to attract

    an enemys attention away rom

    certain objects.

    The graph in Fig. 4 shows how much

    energy from different sources was

    used between 1950 and 2005. We

    can see that over this period the

    amount of energy used increased

    sharply, and the largest amount of

    energy came from petroleum. In

    1950, just over 13,000 million billion

    Joules were used, but this figure rose

    sharply to reach a peak of roughly

    40,000 million billion Joules in

    1978. There was a dramatic fall to

    just over 30,000 million billion in the

    following five years, before

    rising rapidly to reach 42,000 million

    billion Joules by 2005. The second

    and third largest sources of energy

    were natural gas and coal, which each

    accounted for about 25,000 million

    billion Joules in 2005. The graph

    shows that insignificant amounts of

    energy came from renewable sources

    during this time, but there was a

    growth in the amount of nuclear

    electric power after 1970, reaching

    approximately 8,000 million billion

    Joules in 2005. The fall in energy

    consumption in the years around

    1980 was probably due to the world

    oil crisis.

    passengers choose to travel by road, accounting for 58%, while just underhalf of all cargo is carried by road. About a third of all passengers use rail

    transport but only 11% of Croatias cargo goes by rail. Croatia has a long

    coastline, and just under a third of Croatias cargo is transported by sea.

    However, only 9% of passengers use this form of transport. This is probably

    because sea transport is cheaper for cargo but too slow for passengers.

    Pipeline and inland water transportation account for 8% and 1% of cargo

    transportation, respectively.

    2 Because rain only falls during certain months of the year and

    there is only limited finance available, it is essential to find an

    irrigation system that is cost-effective.

    The aim of this report was to find the most suitable method of

    raising ground water, with the main criteria being cost, low

    maintenance, and ease of use.

    This report presents two irrigation systems: the treadle pump

    and the diesel pump.

    A description and an analysis of operational efficiency for each

    pump are followed by a comparison of the two designs. Finallythe most effective pump is recommended.

    This report compares fourteen different practical measures that can

    be taken in order to find the most effective way to reduce the costs

    of heating an average home in Britain and reduce carbon emissions.

    To achieve this, the research compares the cost of installation, the

    number of years required to pay back the investment cost, and the

    amount of carbon saved each year. The study shows that the cost of

    insulating loft and walls is recovered within three years but saves

    only a small amount of carbon. Although it takes approximately

    thirteen years to pay back the cost of installing a ground source heat

    pump, it saves the maximum amount of carbon and is, therefore, the

    best long-term solution. Based on the research, we recommend that,

    where possible, new homes are fitted withground source heat

    pumps.
