Patent application: Load-bearing structure

Ben Welter - Tuesday, July 18, 2017

U.S. patent application 20170197752 (applicant Airdex Corp., Henderson, Nev.):

"The present invention provides a movable load bearing structure with a surface that includes antimicrobial agents capable of eliminating, preventing, retarding or minimizing the growth of microbes and also minimizing cross-contamination when the load bearing structure is being reused for cargos that differ from a previously transported cargo, for example, different food types, such as poultry, fresh vegetables, and fresh fruit. The load bearing structure may be a dunnage platform or a container for storing and/or shipping cargo. ... In an embodiment of the invention, the pockets may be used to locate phase change materials."

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."

PCM briefing: Viking Cold Solutions lands deal in Phoenix; study finds ARPA-E is doing what it was designed to do

Ben Welter - Monday, June 19, 2017

Viking Cold Solutions has announced a collaboration between Salt River Project and Bashas' Supermarkets to install and evaluate the performance of Viking's PCM-based thermal energy storage system at Bashas' distribution center in the Phoenix area. The system is expected to significantly reduce energy costs by shifting peak demand to nighttime hours.

A six-year study finds that ARPA-E, the U.S. Energy Department program that supports cutting-edge energy technologies, is meeting the goals of the 2007 law that created it even as the Trump administration seeks to eliminate its funding. The National Academies of Sciences, Engineering and Medicine report concludes that the program is moving in the right direction and does not require major changes to keep bringing new energy technologies to market.
