As energy efficient environmentally conscious engineers, we here at Glew Engineering do what we can to save energy and resources both around home and around the office. This might mean choosing products that are more environmentally friendly or energy efficient. It might mean using our surroundings to our advantage, like pulling cold air through a home or office at night so the building needs less air conditioning the next day. The most satisfying thing, though, is to employ our knowledge of mechanical engineering, materials science and thermal management to design custom hand-tooled solutions. In the next few blog posts, I'll review some of the current in-house engineering projects that are underway here and maybe give our readers a little inspiration [...]
Figure 1: Composite layered heater from patent US 9,224,626 B2 Alexander Glew, Ph.D., P.E. recently contributed to a new patent on an advanced thin-film electric heaters, layered composite heaters, for CVD semiconductor processing and related technologies titled “Composite substrate for layered heaters”. Watlow Electric, based in St. Louis, hired Glew Engineering and Dr. Glew to help develop this heater technology due to his experience in the Silicon Valley’s semiconductor industry. As a semiconductor equipment expert and materials engineering consultant, Dr. Glew’s familiarity with semiconductor manufacturing meant he understood both the limitations of common semiconductor chuck heating methods and the techniques that could be used to construct a better heater. In this post, we review how this composite heater capitalizes on semiconductor [...]

Figure 1: Mars Exploration Rover By NASA/JPL/Cornell University, Maas Digital LLC [Public domain], via Wikimedia Commons Depending on which Facebook pages or Twitter feeds you follow, some of you may have caught wind that Opportunity (Mars Exploration Rover B, Figure 1) recently passed its twelfth anniversary of its landing on the red planet. Opportunity’s ongoing trek across Mars represents a fantastic accomplishment in engineering. At the time I’m writing this, the rover has been in continual operation for over 4,300 Earth days (that’s about 4,185 Sols, or Martian days). Considering its original planned mission time of 92 Earth days, Opportunity has exceeded its design lifetime by 4,700%. Imagine having a car that, instead of a [...]

Thermal Analysis of Espresso Cup Materials In our blog this week focuses on espresso coffee and the material of the cup in which it is served. The three standard materials that will be tested are paper, Styrofoam and ceramic. Paper cups are designed for cold drinks, so it is likely that they will result in the lowest amount of thermal energy retention in the espresso coffee. Styrofoam cups are designed as a cheaper and single-use alternative to standard ceramic coffee cups. Since they have the ability to handle a large range of temperatures, they will be able to manage the thermal energy in the espresso coffee. Ceramic cups are designed to handle extremely hot temperatures and then be washed [...]
