The UV-activated thermal energy storage material shows the rapid crystallization and heat discharge upon visible light (blue LED) illumination. (Grossman Group at MIT)MIT researchers have combined conventional phase change material with an organic compound that responds to a pulse of light. "The new system," MIT News reports, "uses molecular switches that change shape in response to light; when integrated into the PCM, the phase-change temperature of the hybrid material can be adjusted with light, allowing the thermal energy of the phase change to be maintained even well below the melting point of the original material." The system could be used in a thermal battery to store heat from the sun or any other source and release the heat when needed.

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.

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."
