Sam White has found a new way to stay cool – by taking technology used to chill milk in India, to create cooling necklaces.

In 2010, White, co-founder of Promethean Power Systems, was working and living in India with his wife when he came up with the idea for the Nano-Ice Cooling Necklace.

At the time, White and his team at Promethean Power Systems were working with dairy farmers in India to help them find ways to chill their milk for market.

“We discovered a pretty big problem of farmers in India not being able to generate power to chill milk,” said White.

The technology uses a cooling system that causes many ice crystals to form within a compact space, enabling hours of cooling. According to White, the technology helped over 25,000 dairy farmers chill their milk and move away from diesel generators.

While living in Mumbai the heat was oppressive; White’s wife, in particular, struggled.

“You’d step out and it was a wall of heat,” White said.

Looking to offer her some relief, White took some of the cooling balls that were left over from the cooling system, wrapped them in cloth and gave them to his wife to wear. The necklace made all the difference.

According to White, even in Mumbai’s intense heat, the necklace lasted for hours.

The necklace strings together multiple plastic balls encased in different cloth patterns. The balls contain a water-based solution that freezes, like the dairy cooling system, and creates multiple ice crystals in a compact space.

White launched a Kickstarter in 2015, expecting that the necklace would help a few people who find themselves constantly battling the heat.

“I was sure it was going to be maintenance workers and chefs,” he said.

Instead, White discovered that the necklace was not just popular among those who struggled in the heat, but that it helped provide relief for women with menopause, those with multiple sclerosis, and cancer patients.

“If you can prevent the heat you can dramatically reduce the symptoms,” White said.

When Brookline resident Carolyn Adamson-Mohan saw a neighbor wearing the necklace, she immediately had to know what it was – and when she found out, she immediately ordered one.

“I learned what it was all about and it was a wonderful wonderful thing for me,” said Adamson-Mohan.

As someone who struggled her whole life with heat, Adamson-Mohan said the necklace was the perfect solution as is keeps her cool for hours, looks good and does not melt like an ice pack or damp cloth.

White’s motivation to continue offering the necklaces is the feedback he gets from customers about how the necklace has helped. It is how he learned that the necklace helps those with MS and cancer.

Like with the initiative to help dairy farmers, White’s goal is for a product to have a social impact.
