Using the Fork in a Tree
Currently, when trees are harvested, the places where tree limbs fork are cut out and used for mulch or other low tech uses. Researchers at MIT are discovering that these forks in trees are actually extremely strong and have load carrying properties that cannot be duplicated even by processes like 3D printing. Dr. Caitlin Mueller, Associate […]
Researchers Create a Better Carbon Dioxide Filter
Scientists at the University of Delaware have developed a method to efficiently remove carbon dioxide from the air using technology from fuel cells and, in doing so, help solve a roadblock to adopting fuel cell technology. The research team work with hydroxide exchange membrane (HEM) fuel cells that convert hydrogen to water and produce electricity. […]

Dog Saved After Drone Carrying Sausage Lures Her To Safety
We keep learning about new ways drones can be useful. In a recent dog rescue in England, the creative rescuers used a drone, with sausages attached, to lure a dog to safety and out of the way of a rising tide on mud flats. – Daniel Findley, DTC Engineering Economics Instructor PE Exam Prep That Works!Pay Up […]
FEATURED TESTIMONIAL – “Not only did I pass, but I felt confident throughout the exam.”
“I took the Thermal and Fluids CBT exam, and the first thing I want to say is: I PASSED! I was very happy to see that all of my hard work and discipline paid off. I went through your course in the standard 20 week timeline and put in 15-20 hours of studying per week. I […]
New Ways to Turn Waste Heat into Electricity
Researchers at Penn State have developed a practical way to harness the energy from curved, hot surfaces and convert it to electricity. Devices known as thermoelectric generators have been around for some time. They use silicon and other compounds to convert heat into a small electric current. These devices have been mounted onto rigid metal […]
Immersion Cooling Technology Gaining Ground in Data Centers
Cooling of data centers is one of the US Department of Energy’s challenges and poses a real challenge for HVAC design engineers. Traditionally, this has been done by blowing large volumes of cold air through the building. Directing the air through the racks to pass over cooling fins to dedicated return air aisles behind the […]
FEATURED TESTIMONIAL – “Seemed Tailor-Made for Me”
“I took the Mechanical TFS CBT exam and I received a passing result. When I learned that my current career may have hit a roadblock and I needed to do something about it, I wasn’t sure where to start. I reached out to a coworker who is a former DTC student. He referred me to […]
What Color is Your Hydrogen?
A recent Infographic by Jeffrey Winters, Editor-in-Chief of ASME magazine, highlighted how the different types of hydrogen are identified using color codes. The different hydrogens are not actually different colors, all are colorless, however since it must be manufactured, the different processes have been given a color code. For example, “brown” hydrogen is the least expensive to […]
