Indian inventor develops 'climate-controlled' jacket to heat or cool wearer


May 28, 2011 - London

An Indian inventor has developed a jacket that keeps the wearer comfortable in extreme temperatures.

Kranthi Kiran Vistakula's state of the art ClimaWare-jacket uses Peltier light weight plastic plates with a thermo electric device, reports BBC.

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.

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, explained Vistakula.

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

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

His 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 said.

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

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

He is even considering a special jacket for cows.
