• Nantucket, Mass., has approved the installation of an Ice Bear thermal storage and air-conditioning unit in a building owned by the town. Last summer, Genbright won a $1.5 million grant from the state to install the units in more than 200 Nantucket homes, with the goal of reducing peak energy demand and staving off the need for a third undersea power cable for the island. But some residents voiced skepticism about the technology, prompting the town board to approve the test installation.

• Shippers have found that cocoa butter can be hard to contain on long ocean voyages. There have been reports of the material leaking out of containers as it changes phase, clogging bilges and generally making a mess. The Cargo Incident Notification System, established in 2011 to share information on all cargo-related incidents, has issued guidelines that recommend the material be shipped in refrigerated containers, particularly when passing through hot climate zones.
