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.

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

that you convey it to your DODO, as you are the mouth piece for it. For your info peltier modules are available else where also. He is importing those TEC modules!!!!
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.

country's defence is first to a defence R&D Engineer like me. beg,borrow,steal anything is fine. you argue for your clients on IPR on karolbagh pavements.That will work fine for you.
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.

India is rich with talent and these are the instances when we really wake up to this fact. Great going ISRO!

I came across this news while looking for jackets to wear this winter. This is what I wanted to buy - a simple winter jacket for normal use. This is what Google showed me - a high tech jacket for -40 degree Celsius cold. Wow! It was a funny co-incidence but it nonetheless made me really proud of the country that I live in.
