To Help Dad, Varanasi Girl Innovates Belt That Cools Water Using the Hot Sun

Varanasi BCom Student belt for Daduilds Solar Cooling

Varanasi student Aanchal Singh has innovated a solar cooling belt, which when placed around bottles, cools the water inside. Watch this video to see how.

Innovations are usually born out of requirements. In Aanchal Singh’s case, she had seen her father labour in the heat for years, without cool water to drink. He worked at a fuel station, and his bottle of cold water would heat up in minutes.

To help him combat the heat, Aanchal decided to innovate a solar cooling belt.

The BCom Student, who resides in Varanasi, designed a belt that can be fastened onto any water bottle. When exposed to the sun, this belt uses solar energy to cool the water.

This ‘Make in India’-inspired innovation has a solar plate and thermal cooling plate that capture solar energy. It fits onto any bottle like a clock. The device also has a cooling fan and rubber belt, and all it needs to work is the sun. As the heat increases outside, the bottle is cooled faster. In fact, it takes just about an hour to cool one litre of water.

After seeing her innovation, Meerut’s MIET College Atal Community Innovation Centre has promised to help improve the device further. The vice-chairman told Economic Times, “We are always ready to promote this type of innovation. Solar energy, used as alternative energy, is now becoming an important part of our energy needs. This is a very cool invention that will keep the bottle cold without electricity.”
Meanwhile, Aanchal says that the government should step forward to support young innovators like herself.

Wouldn’t it be great if such an innovation could become a handy substitute for refrigerators someday?
