    New jacket Invented in India, tested by Indian army in -40C at Siachen glacier

    Mr Vistakula the inventor wearing same jacket


    By Omer Farooq BBC News, Hyderabad

    Kranthi Kumar Vistakula models his climate-control jacket Mr Vistakula says he is even considering designing a jacket for cows

    An Indian inventor is developing clothes which keep the wearer comfortable in extreme temperatures.

    Kranthi Kiran Vistakula started with a jacket and is now applying his idea to shoes, scarves and even dinner plates.

    The clothes use Peltier light-weight plastic plates with a thermo electric device.

    The device is powered by rechargeable batteries which can be topped up by vehicles or even solar panels. They can last up to eight hours on one charge.

    Mr Vistakula works with an enthusiastic young team in an isolated building near Hyderabad city, the capital of the southern Indian state of Andhra Pradesh.

    Outside, the summer temperature is more than 40C. But Mr Vistakula looks as comfortable as if he is in a cool climate.

    He is wearing a state of the art ClimaWare-jacket based on his own patented technology.


    A Peltier plate consists of a junction between two metals. When an electric current passes through the junction, metal on one side heats up and on the other side it cools down, he explains.

    The climate-controlled jacket, which weighs a little more than 1kg, has been successfully tested by the Indian army in Siachen glacier where temperatures are as low as -40C in winter.

    Mr Vistakula's company, Dhama Innovations, is now developing a range of other products using the same technology.

    "We have also developed shoes and they have been immensely liked by the army personnel in Siachen glacier," he says.

    Frostbite is a big problem for the army and the shoes have really helped, he said.

    Jacket for cows

    Mr Vistakula is now setting up a manufacturing facility near Hyderabad for the mass production of his products, which include jackets, shoes, scarves, gloves and ear muffs. :cheers:

    He is even considering a special jacket for cows.

    "Basically when the cow is cooled, it gives more milk in summer," he explained. "So we're working on a jacket like that - a huge one."

    Mr Vistakula says he started to develop the idea when he moved from his home city of Hyderabad to study engineering at the Massachusetts Institute of technology.

    The difference in temperature came as a shock to him.

    His first attempt weighed about 5kgs and had wires and fans. Everybody joked that he looked like a bomber. Then he started using Peltier plates.

    There may also be a medical application for the technology. The team is working on a product called Haemosave which can freeze blood oozing out of a wound.

    It is described as a potential life saver. It uses cryo or ice therapy to stop the blood flow and contract the blood vessels.

    Other medical products include knee, neck wraps and elbow wraps. These devices can go instantly from 0C to 50C and help in controlling pain.

    Indian Defence industry has to be privatised and localisation has to be encouraged. we cant even produce small infantary items like shoes (im glad DMS has been replaced), helmet, jackets, gloves, backpacks, BP Jackets, goggles, side arm, primary weapon (assault rifle)......

    kudos to this gentleman who has produced this jacket.

    remember kargil, when we had nothing to be used winter/snow clad areas!

    An MIT grad who wished to use his patented technology in India for the world not something you see often.This will save a lot of lives for soldiers and This is one hell of a leap when compared to what happened in Kargil.

    Lt.Gen H.S Panag always states this

    Nanotech Clothing Warms in Winter, Cools in Summer

    A freshly developed nano-tech turns your clothes into personal A/Cs and heaters.
    As a student at MIT perpetually whipsawing between the bone-chilling, soul-crushing cold of the Cambridge winter and his centrally heated dorm, Kranthi Vistakula alit on an idea: clothing whose climate you control.

    Thus was born ClimaWare, a line of jackets, shoes, helmets, and other gear that transforms on demand into personal heaters or A/Cs. At the press of a button, the apparel can get as cool as 64 degrees F and as hot as 104 degrees F for up to eight hours on a single set of batteries. And it’ll work in all kinds of ungodly weather -- Dubai in July, Alaska in January. Though you wouldn’t want to try it out in Antarctica, where the mercury regularly drops below -40. (ClimaWare is only effective when the outdoor temp falls between -22 degrees F and 122 degrees F.)

    The technology at play here is an adaptation of the Peltier Effect, which occurs when electricity is run through two different metals connected to each other: One metal will become cool, while the other metal will become hot. Vistakula's nano-based technology uses that effect inside those puck-like inserts on the vest above. Thermoelectric materials that touch the skin either heat or cool your body; it's your choice. The pucks are placed at points where sweating is low, but blood vessels are very dense -- in other words, the most efficient places for regulating body temperature.

    [Thermal imaging shows skin temperature after wearing the ClimaWare jacket for 5 minutes; cooling above, heating below]

    The Indian edition of MIT’s Technology Review named Vistakula a 2010 “Innovator of the Year”. For a diagram of the tech, see here.

    ClimaWare isn’t the first climate-controlled apparel on the market. But Vistakula says what sets his India-based company Dhama Apparel Innovations apart is that his products are extremely lightweight, which makes them ideal for athletes, soldiers, and pretty much anyone who doesn’t want to look like this come winter. The jacket weighs about as much as a pair of jeans.

    The technology also has vast potential in other industries, including health care and the military. According to Technology Review, quoting Harshal Shah, whose company has invested in Dhama Apparel, Dhama's product team is working with the Army to develop a heating and cooling mechanism for missiles.

    The pelter effect module technology can be used to cool electronic equipment in tanks and APC where temperature reach 60 deg C inside. one example is the Catherine Thermal imaging system opted for T-90 tanks can be cooled to operate in indian summers using a variant of this technology.

    Features & Benefits
    Extremely lightweight (~ 800 g
    excluding batteries; weight of
    battery ~ 600 g) and
    manageable to maximize
    performance and facililate easy,
    unrestrained movement.
    The USP of the technology is
    that it combines heating and
    cooling in a single jacket, so the
    same jacket can be used in
    multiple places of military duty.

    18-22 points strategically placed
    on the torso give maximum heat
    dissipation.
    Our unique system, for the first
    time, empowers the wearer to
    control the temperature inside
    the jacket, within a range that is
    optimum for performance and
    protection. Temperature range
    (inside jacket): ~ 18o C (64.4o
    F ) to ~40oC (104o F) Operating
    ambient temperature: -30o C
    (-86o F) to 55o C (131o F).

    Enduring quality and robustness
    that is immune to damage in
    adverse conditions.
    The construction uses State of
    the Art technology for absolute
    precision and perfection.
    Easily rechargeable LiPo (Lithium
    Polymer) batteries, which come
    in the form of a convenient
    detachable belt, power the
    system. A single charge of
    battery lasts up to 8 hours of
    complete performance.
    Unique fabric technology
    characterized by high wicking
    action, advanced breathability
    and anti-bacterial
    treatment
    ensures enhanced comfort and
    odor-free prolonged use. The
    jacket is perfectly contoured for
    an excellent fit and ease of
    movement.
    SIMO (Single Inner Multiple
    Outer) construction technology
    provides the flexibility to use the
    same inner layer (embedded
    with the heating and cooling
    technology) with varying outers
    to comply with uniform protocol
    and codes of conduct.

    For a high-technology heavy-
    duty performance jacket, it is
    surprisingly easy to wash and
    maintain. The inner layer can be
    cleaned using a wet cloth or
    sprayed with water steam when
    in a hanging position. The
    detachable outer layer can be
    taken off and given a normal
    regular wash.
    Assured safety with the use of CE
    certified electronic components.
    100% Warranty for one year
    extendable to three years.
    Maximum protection and
    maximum performance with
    minimum weight addition.
    ClimaWare - Jacket for the
    soldiers working constantly
    under extreme temperatures.
    Carrying 30 to 40 pounds of gear
    under a blistering 40oC sun
    could easily lead to heat
    exhaustion, heatstroke or even a
    loss of life. Yet soldiers brave
    these conditions everyday in
    hostile locales with extreme
    temperatures that make survival
    a challenge for them.
    Our
    revolutionary product lessens
    their ordeal without adding to
    their burden.
    The ClimaWare-extreme
    performance jacket, ingrained
    with unique high - technology
    heating/cooling function, is
    specially designed for use by
    soldiers. Weighing no more than
    a regular pair of denims, it is an
    extremely lightweight product
    that aids survival and enhances
    performance without hampering
    movement and agility. It is
    designed to combine
    compactness and ruggedness to
    match up to the toughest of
    military requirements.

    HAEMOSAVE.
    .
    More lives are lost to blood loss
    than to the bullet itself. And
    therefore, we made Haemosave
    possible.
    Timely prevention of critical
    blood loss can significantly bring
    down soldier mortality by
    increasing the chances of survival
    and recovery. ClimaWare -
    Haemosave is a brilliantly
    designed system that instantly
    controls severe bleeding, pain
    and inflammation by way of
    rapid four-point action: Cooling,
    Coagulation, Compression and
    Sterilization.
    ClimaWare - Haemosave System
    enables contraction of blood
    vessels by applying Ice-Therapy
    (Cryotherapy) with the help of
    optimal prompt cooling points.
    This process called
    'Vasoconstriction' controls
    bleeding, pain and inflammation.
    The cooling points are
    strategically placed so as to
    encircle the injury for maximum
    effective cooling but do not
    press directly onto the wound to
    cause abrasion and cold injury.

    ClimaWare-Shoes give complete
    protection to the feet with
    instant heating/cooling function
    for frostbite and heat-injury
    prevention.

    Since the advent of armed
    conflict, frostbite has always
    plagued large numbers of
    soldiers serving in harsh climates
    with primitive or inadequate
    protection from the elements.
    Feet are particularly vulnerable
    and extra foot care is required
    for cold-weather operations.
    Protection of feet is strongly
    dependent on heat input by
    peripheral blood circulation and
    insulation by footgear. Cold
    numb feet can disrupt balance
    and walking and increase the risk
    of slipping, thereby creating an
    unwarranted danger for the
    soldier's life. Soldiers also face a
    diametrically opposite situation
    where standing duty and
    movement on scorching terrains
    makes their feet susceptible to
    heat burns and injuries.
    Lightweight and extremely
    rugged ClimaWare-Shoes are
    designed to handle both these
    extreme situations for maximum
    protection. They have
    strategically placed heating/
    cooling points that help the
    soldiers maintain vigilance,
    dexterity and strength even while
    treading on threateningly cold or
    hot surfaces.

    Armand. thanks for the clarification,of course not to me. Do you have some idea on how to deal with the heat developed by the peltier module itself. The peltier modules are power hungry. i did see some videos ,where Russia is making peltier modules to cool the electronics in T-90 tanks.

    @venkat you sure have some issues, please understand i only said that if you want to use his patent, pay him royalty, (post no.10) to which you said

    I never said that he is making those peltier modules, but you assume that i have said so, plus it appears that you have issues with DRDO, and you tried to make personal attack against me, saying i am DRDO's mouth piece, well i will do what i like. I did told you to educate yourself with IPR laws, then we will talk, as it appears you are not aware about IPR.

    for your info, i argue IPR cases in High court. Again for second time you did not hesitated in making personal attack, saying i will argue on Karolbagh pavement, i think you dont even know basic things about our legal process , specially the fact that Koral bagh does not have any civil court.

    If you steal other's IPR you are no better then what chines are doing.
