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 […]
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 […]
Eiffel Tower Goes Green with New Refrigerant
Eiffel Tower goes Green with New Refrigerant As the world pays more attention to carbon dioxide and improves its energy efficiency, refrigeration engineers are looking at the harmful impacts their refrigerants create when released. Original refrigerants R-11 and R-12 were very efficient, but destroyed ozone. So, R-22 and later R-134a were developed to have low […]

Beep! Beep! Down It comes!
I don’t think there was any episode of the Road Runner TV show in which Wile E. Coyote didn’t try to drop a boulder on the Road Runner. Wile E. was never successful. There is, however, a company in Switzerland, Energy Vault, that has designed and built a prototype system that works on the same […]
FEATURED TESTIMONIAL – “Gave Me the Confidence Needed!”
“Thanks to Dr. Tom’s Classroom I was able to successfully pass my Mechanical Systems PE exam. I completed undergrad almost 30 years ago, and Dr. Tom’s provided me with the refresher and confidence needed to complete the exam. The lessons are well thought out and I was able to complete them in the allotted time. The continued problem […]
Energy Efficiency using 100% Outside Air?
Every HVAC engineer knows that air quality usually improves with the more outside air that is brought into a space. This is particularly true for hospitals and other spaces where indoor air contamination is an issue. However, using lots of outside air means also having to use more energy to condition the air. In many […]
