New low cost ‘Powerless Heating System’ can heat food in remote areas

A new low-cost heating system which can be activated by water anytime and anywhere, and does not require any fuel or electricity to heat or power it, can act as a heating solution in any location.

Lack of heating sources at remote places with no access or uncertain access to power sources is an inconvenience faced by many, especially in remote areas like some of those in the northeastern region.

Sumer Singh, Associate Professor, Department of Design, IIT Delhi along with his research team addressed this with a technology that works on chemical energy. It is called ‘Powerless Heating Technology’.

The active heating element consists of a mixture of eco-friendly minerals and salts, which generates exothermic energy resulting in heat on contact with water.

This provides enough energy to raise the temperature of any food or beverage by 60 to 70 degree Celsius. The weight of the heater is only 50 grams, and after every heating, the by-product (natural mineral rock) inside the heating pad can be disposed of.

The rock helps in improving the fertility of the soil and is 100 per cent biodegradable.

Officials of Ministry of Science and Technology said that with this technology, users can heat ready-to-eat food, make instant noodles, and any beverage like tea, coffee, etc. The by-product of the heating process is a natural mineral that easily integrates into the soil without any toxic effects.

North East Centre for Technology Application and Reach (NECTAR), an autonomous body under the Department of Science Technology supported Singh and his team to develop a food box and a liquid container that can be integrated with the Powerless Heating Technology. They have used it to develop containers which can heat food and beverages on demand.

These products will be of great use to military personnel, tourists, and office-goers in the northeast.

This Powerless Heating Technology eliminates the need for burning forest wood for heating purposes, thus also reducing forest fires, which is a major problem in the northeastern parts of the country.

The prototypes were successfully developed and tested. Several FMCG companies are keen to launch it in the market.
