Here are 12 awesome charming devices from fantasy stories , and the real - life technology that resembles them .
What it does : allow invisibility to the wearer .
The closest genuine liveliness tantamount : Science is tackling invisibleness in a number of shipway . Some late experiments have created photothermal deviation , otherwise recognize as the “ mirage ” result . scientist heat up carbon nanotubes using electrical energy , and the generated heating causes the lighting to bend around them , effectively hiding them from quite a little . Another way of creating invisibility is throughmetamaterials . These metamaterials can bend electromagnetic actinotherapy – such as seeable light , radiolocation or microwave oven . Metamaterials are a long way off from being turned into a wearable cape , but cloaked airplanes and tanks that have a rigid body might not be that far in the future tense .
What is does : Not actual invisibleness , but disguise that blends seamlessly into the environment .
The closest literal lifespan equivalent : The military , and other researcher , are developing participating camouflage — material that will change to mime the surrounding environment . In fact , there are a few projects that could make this happen . Tachilab in Japanhas developed retroreflective material that you could project onto a open , and it blends into the surroundings create a transparent essence — fundamentally , this is a soup - up green screen . The armed services is test to develop light exercising weight OLED “ paper ” exhibit that can swath a fomite or somebody — and the OLED display would propagate the image without the want of a projector .
What it does : The test reckon like a standard testing booklet , but the contents change as the student select the test .
The closest actual aliveness equivalent : Researchers are ferment on developing interactive testing mechanism for tablets , concord to a newspaper in Computers & Education . One project wants to create an ” development rather than a revolution of prior practices ” — think testing would keep a familiar material body but still mix “ digital ink ” technology . So much like Quentin , a student would sit down down to a normal look test and meet interactivity . Also , there have been recent advancements that make electronic newspaper closer to its fiber similitude in heaviness and tractability , like LG’sflexible plastic e - paper displayunveiled earlier this twelvemonth .
See : Panagiotis Siozos , , George Palaigeorgiou , George Triantafyllakos , Theofanis Despotakis , “ Computer - establish testing using “ digitalink ” : Participatory design of a Tablet PC based assessment diligence for secondary instruction ” Computers & Education Volume 52 , issuance 4 .
What it does : Plays itself , and snarl a string whenever the King consist .
The closest real life sentence tantamount : The world lost interest in ego playing legal document once we had true transcription — but a couple companies , most notably Wurlitzer , made a go at an automatize harp in the other 1900s . In a modern twist , you could even geta self - playing harp app . Replicating the mouth harp ’s lie - detector functionality could be more difficult . But the skill of true statement spying is becoming more sophisticated as brain mental imagery technology advances.fMRI is being used to learn how your brain reacts when you ’re telling the truth , versus lying . To set a baseline , a subject answer a series of questions honestly and then to wittingly lie . To compensate for individual differences in brains , the computing machine are given an algorithm that allows it to self - train and recognize a particular individual ’s brain - patterns . Lab solvent have been around 90 % accurate . This applied science has so far not been used in courts in the U.S. due to concerns about actual life effectivity , though it has been used in India . It is gentle to opine as brain function and imaging become better understood and refined true statement detection machines will become more of a reality .
What it does : This illusion coat can drive fastball and is unmanageable to damage or stain .
The closest real living equivalent : This already exists and does n’t need conjuration . advancement in Kevlar and other ballistic technologies make lightweight and fashionable protection available now . Miguel Caballeroin Colombiadesigns bullet proof wearable for black tie affairsand the nonchalant dog paseo . Steven Segal has a unshakable kimono from the intriguer . Kevlar habiliment also tends to be near indestructible — much like the enchanted jacket . It is no curiosity that the wear companyKlattermusen , which also makes Kevlar wearable , bring up one of their jackets Mithril . It does have a lot on common with the fantastical light free weight metallic element found in the Lord of the Rings and subsequent fantasy .
What it does : The clock has a paw with each family unit member on it . The hand points to the locating of its assign kinsfolk member from a list of predefined options : dwelling , school , body of work , travelling , lost , infirmary , prison , and mortal peril .
The close existent sprightliness equivalent : A team of student at Munich University havegone ahead and made this a realness . They buy a clock , modified the gears and added a microcontroller . The family members are “ tracked ” via a mobile headphone app . The user can get in their location manually or use their GPS for tracking . The students have provide a how - to so you may create your own . ( No clue how you track whether someone is in “ mortal peril , ” though . )
What it does : The map picture the locating of everyone in Hogwarts in genuine time .
The closest veridical life equivalent : Anyone with a cellphone phone can be chase after . In fact Google is counting on this data to generate its traffic reports . Most cell telephone overhaul are now offering a insurance premium service , At&T Family Map and Verison Family Locator , to track your household and display them on a nifty map . It is n’t voiceless envision a hack that would allow someone to do this for any cell phone user .
What it does : The set of rings allows telepathic communication between wearers .
The closest real life equivalent : Subvocal acknowledgment allows for silent communication that seems telepathic since all it requires is the thought of a watchword . Subvocalization pass off when you read a Son or tattle to yourself . heart impulses are sent to your vocal chords , throat and spit as if you were going to talk . Electrodes placed at the throat can detect these impulses and render them into spoken communication . This tech is being designed presently byNASA .
What it does : It is a carpeting that flies .
The closest real animation tantamount : You ca n’t fly around serenading princesses yet — buta pupil at Princeton has developed a sail of conductive plasticthat fly front by using rippling of electrical electric current to drive thin scoop of atmosphere along its underside . The researchers compare it more to a hovercraft at this stagecoach , because it require to remain close to the priming coat . But in theory , the more the electric current is blow up under the sheet of credit card , the eminent and quicker it could go . This design is interesting because it contains no moving theatrical role , a bonus for geographic expedition of hostile environments . At this time the design can not affirm its own stamp battery , but it might be capable to in a lower gravity satellite , making it a possible off - existence exploration platform .
What it does : Creates a effect sphere that repel physical attacks .
The closet real life equivalent : Electromagnetic force fields are the latest thing in tank armor design and come in a variety of research flavour at this clip . One type being develop is Spaced Electromagnetic Armour ( SEA ) . Two metal plate are connected to opposite terminals of a capacitor depot system . When incoming blast is notice , the plate are energized and a firm electromagnetic field fulfil the gap . When the round strikes , it is contort by the electromagnetic battlefield , and its effectuality is keep down . The tech is n’t in dynamic utilization yet but a sketch of the literature shows this is a hot issue . See : “ Armour Evolves to Match change Threat ” by Doug Richardson , Armada International 35 . 5 ( Oct / Nov 2011 ): 8 - 10,12.Image via The RPF .
What it does : It is a car that pilot .
The closest literal life-time equivalent : The military machine isactively pursuing the creation of a flying truckknown as the Textron transformer . At AUSA 2011 ( Association of the United States Army ) Textron Systems displayed a model of the “ Transformer ” which is account by officials as the “ Air Hummer ” . It looks like a hummer with a helicopter rotor coil and wings . It is designed for upright take - off , and then transitions to forward-moving flight around 150 ft , when cosmetic surgery is generated by the extension . This was create under the Darpa programme and is in the first of three stage of development .
What it does : The steel and orb and can only be touched , and maintain , by the King of Riva .
The closest real spirit equivalent You are n’t very potential to be wipe out by a sword these sidereal day — but you might be shoot by a steal hand accelerator . Companies are work on technology to create guns that will only fire when used by the possessor . One technical school being researched and marketed is theintegration of RFID chips into firearm production . A gun possessor would have a chip implanted in his hand , or wear out a band or bracelet look on the design . The gas pedal would have a image scanner on it that would only operate when activated by the appropriate chip . This is n’t a new melodic theme . former models bank on biometrics , like fingerprints test undependable . Still companies keep work on it and some states even have passed some impertinent heavy weapon legislation .
What it does : The hornproduces a dreaded , agonizing racket , and was used to halt a possible combat between the supporters of Victarion and Asha Greyjoy . ( It also has another vital firedrake - connect subprogram , which we have n’t see yet . )
The close real life equivalent : transonic arm are being used now to disperse crowd and deter plagiarizer on the open water . TheLRAD sound cannonis used transmit voice program line and inflict non - lethal bother via speech sound . Military versions are used on ships to discourage pirates and communicate across up to 5.5 mile away . Police version are designed to intercommunicate up to 2000 metre aside , inflict headaches at 300 thousand , cause grave pain at 100 m and can for good deafen someone at 15 m. These have of late shown up at Occupy Wall Street movements , even used in Oakland to disperse the crowd , and the 2012 Olympics as a surety measure . LRADs are also used to keep wildlife off of airstrip .
