PCM briefing: 'New paradigm' in pharma cold chain; opening for sales manager at Sonoco ThermoSafe

Ben Welter - Monday, July 24, 2017

GoSun solar stove• The makers of the GoSun portable stove, which uses solar energy to bake, roast or steam food at temperatures up to 290° C, have raised nearly $400,000 from investors on seedinvest.com. The stove initially used high-temperature phase change material to store the sun's energy. "We abandoned the PCM a couple years ago after we started doing testing with it," said GoSun's Matt Gillespie. He said the material did not match the performance promised by the PCM maker, degrading "significantly" after just a few cycles. The current design uses compound parabolic reflectors and a horizontal vacuum tube to convert nearly 80 percent of sunlight into usable heat. The Cincinnati company has sold 10,000 stoves online and in retail outlets such as Home Depot, REI and Cabela's. GoSun plans to use the SeedInvest funds to support continued growth.

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."

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.

Patent application: Returnable cold chain packaging composite

Ben Welter - Thursday, June 15, 2017

U.S. patent application 20170158411 (applicant Proprietect LP, Toronto, Canada):

"Provided is a reusable composite container comprising a thermally insulating inner container fitted within a durable outer container. The outer container can also be thermally insulating. In preferred embodiments, the inner container comprises expanded polystyrene and the outer container comprises one or more of expanded polypropylene (EPP), EPS (Polystyrene), EPE (Polyethylene), PEPP (porous EPP) and PS/PE (Polystyrene/Polyethylene). The composite container can be used to ship temperature-sensitive payloads such as perishable goods.
