The previous blog, Entropy Happens… Deal with It! ended with the statement, “That’s how Concepts NREC deals with the constraints of the Second Law of Thermodynamics when designing high-efficiency...
If there’s one thing good about sitting in snarled traffic in Boston, it’s that you get to see some very original bumper stickers. The most recent bumper sticker I saw was probably the strangest one,...
When discussing the efficiency of transforming one form of energy to another, circularity is the way to go. Anyone who has spent even a little time studying engineering thermodynamics knows that the...
It sounds like an opening to a joke, but I wanted to share some creative thinking sparked during a field trip to a local gas turbine cogeneration plant with some undergraduate students I teach. The...
I am an engineer and teacher, so as the year draws to a close, I like to look back on memorable events where an engineering activity went, or almost went, awry. Luckily all were caught in the nick of...
Credit for the first gas turbine engine used in flight is given to Dr. Frank Whittle. Dr. Whittle maintained a steadfast commitment to developing gas turbine-powered aircraft in the midst of World...
The AS9100 Certification identifies companies who have qualified to manufacture products for the Aerospace Industry. Manufacturers who meet the extensive requirements of the AS9100 Certification have...
Boston, MA is known as a walkable city. Boston’s downtown area is very small, relative to those in other cities. However, the walkable size provides you with a special opportunity to explore the many...
My gym has been crowded with a lot of new people these past couple of weeks. It happens every year in January as people try to stick to their New Year’s Resolution to exercise more. I don’t mind the...
Have you ever been to the beach on a very hot day? Then I am sure you noticed that the sand is very, very hot, uncomfortably so. Congratulations, you have had first-hand experience with ground source...
There are not many people who would argue that if you only received 30% of a commodity that you need to purchase every day to enable you to have your share of “…life, liberty and the pursuit of...
The 2015 Paris Climate Talks (COP21) were successful in achieving consensus from 196 countries that climate change must be given significant attention. There was a particular focus on the release of...
The contemporary gas turbine engine, developed in the 1940’s by Sir Frank Whittle (pictured), is stillconsidered to be among the most efficient, external combustion engines. Today, there is a...
Sisyphus in Greek Mythology was condemned to eternally roll a large rock up a hill only to watch it crash to the bottom. The myth lives on today with the term Sisyphean that refers to tasks that are...
