PCM briefing: A baby manikin that sweats; a salt and antifreeze TES system

Ben Welter - Thursday, August 03, 2017

Alphabet Inc.'s secretive development lab is developing a system for storing renewable energy in tanks filled with salt and antifreeze. "The system takes in energy in the form of electricity and turns it into separate streams of hot and cold air," Bloomberg reports. "The hot air heats up the salt, while the cold air cools the antifreeze, a bit like a refrigerator. ... Flip a switch and the process reverses. Hot and cold air rush toward each other, creating powerful gusts that spin a turbine and spit out electricity when the grid needs it. Salt maintains its temperature well, so the system can store energy for many hours, and even days, depending on how much you insulate the tanks."

Thermetrics baby manikinThermetrics LLC has introduced an 11-zone thermal baby manikin that features a thermally conductive carbon-epoxy shell, a “sweating skin system” and internal heater elements and temperature sensors. Nicknamed “Ruth,” the manikin can be used to evaluate the thermal properties of clothing, diapers, bedding, car seats and strollers.

From Italy to Singapore by bicycle, with a little help from PCM

Ben Welter - Monday, July 03, 2017

Italian couple celebrate completion of 18,000-kilometer ride to Singapore

They made it! The Italian couple who embarked on a 17,550-kilometer bicycle trek last June arrived in Singapore last week. Chiara Ricciardi and Riccardo Rocchi began the yearlong journey, dubbed "Piece of Cake," to raise awareness about diabetes. Ricciardi has type 1 diabetes and requires a daily dose of insulin. She used Pelican BioThermal's Credo ProMed pack to keep insulin at the right temperature. 

Their latest Facebook post: "385 days. 21 countries. Bottom line: with type 1 diabetes, you can do it. But also ... We've learned that the world is a better place than they say, people help and help you. ... The engine is overrated, time is the biggest luxury of the 21st century."

Outlast Europe's Martin Bentz spoke with T.EVO magazine this month about the company's new Xelerate fabric. The fabric, introduced at a German trade fair earlier this year, incorporates "heat spreader" technology, a process traditionally known for cooling electronic devices. Xelerate fabric features improved thermal conductivity, Bentz said, and is suitable for home textiles, sportswear and protective gear. In an email exchange with Phase Change Matters, Bentz declined to discuss specific partners or customers.

Warmilu, maker of the IncuBlanket infant warmer, reports that is on track for $300,000 in total 2017 sales after signing two distributors for Latin America, Africa and Southeast Asia: Relief for Africa Foundation and Maternova. The IncuBlanket, which has been successfully tested in clinical trials in India, uses packs filled with sodium acetate trihydrate to keep infants warm for up to five hours. CEO Grace Hsia says the device recently cleared its first regulatory filing with Kenya's Pharmacy and Poisons Board.

Thanks to PCM insert, luxury chocolates melt in your mouth, not in the box

Ben Welter - Monday, February 20, 2017

In hot climates, chocolates bought at retail shops can end up melting on the way home. Pluss Advanced Technologies of India has introduced a packaging insert to keep the sweets in solid form during transit.

Pluss PCM insertDeveloped for ITC’s Fabelle line of premium chocolates, the insert features inorganic phase change material contained in a non-woven film. Vishnu Sasidharan, vice president of new product initiatives at Pluss, says the PCM was customized to keep the chocolate between 3º and 9º Celsius. The insert, designed for one-time use, measures about 170mm x 70mm. The goal is to maintain product quality and texture for one to two hours.

“The product was launched about five months back,” Sasidharan says. “It was available only in one hotel chain within ITC group of hotels. The boutique has gained much traction only in the last few months with ITC expanding it to not only within their group but in all the 5 star/7 star hotels across India.”

Pluss is working with other chocolate/confectionary companies to offer similar solutions for premium temperature-sensitive products.
