The National Institute of Standards and Technology (NIST) has invented two new methods of measurement that could lead to better designs for cooling systems. Agency engineers devised a way of using fluorescent light to help choose the best lubricant for keeping a compressor running smoothly. Research indicates that certain lubricants that partially mix with the refrigerants and have high viscosity can improve the performance of the refrigerants as much as 18%. NIST researchers also developed a calorimeter that measures heat conducted through a new class of insulation panels and around their edges. The device recently measured new vacuum insulation panels that use a novel fill material developed by Dow Chemical Co. The calorimeter found that the panels have an R-value about six times higher than traditional glass-fiber insulation. A panel 2.5-cm thick had about the same R-value as 15 cm of glass-fiber.

The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
