Predictive Algorithm Reduces Energy Use at Hong Kong Airport
Hong Kong Airport’s Terminal 1 is using an adaptive algorithm that predicts the building’s cooling needs over the next 24 hours. Weather – including cloud cover / solar radiation, temperature, and humidity, as well as the schedule of flights and other activities are input. The demand for the next day is estimated from the data […]
FEATURED TESTIMONIAL – “Gave Me All the Information and Skills I Needed to Pass”
“I’ve been out of school for 5 years now, and I feel like I didn’t have a very good grasp of the material I would need to master in order to take the TFS PE exam. While looking for classes to sign up for, I came across Dr. Tom’s Classroom and saw a number of […]
Weed-Killing Lasers in Your Garden?
The key to successful gardening is weed and pest control. Currently that task falls to either manual labor or through the magic of chemistry. Those two methods are also the hallmark of successful farming as well. A recent ASME article profiled an autonomous weeder introduced by company located in the northwest US, Carbon Robotics. This weeder is […]
Around the World via Solar, Wind and Hydrogen
There are three technologies that are changing the designs of modern ships: solar, wind, and hydrogen. A fascinating CNET video describes a research vessel that is using all three technologies to achieve a fully self-sustaining travel. It is called the “Energy Observer.” Solar panels collect energy from the sun during the day and then it is […]
FEATURED TESTIMONIAL – “Save Hundreds and Get a Better Course”
“I followed the course, watched the lectures, worked the problems, did the quizzes, submitted questions on the online forums and then I passed the test. There were many nights that I was worn out and it took everything I could muster just to stay awake to watch a lecture or do a problem, but I was […]

“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 […]
Does the Earth Have a Pulse?
It’s been assumed that major geological events such as volcano eruptions and sea level change are random and may be a result of entropy, and there is no pattern to these events. According to a SciTechDaily article, NYU researchers plotted the number of major geological events for the last 260 million years and the simple […]
Like Floating a Bus on a Tall Pole
Offshore wind turbines have to date been mounted on foundations resting on the bottom of the ocean. This design best resists the forces from wind and waves. Currently the deepest this design can be used is 60 meters. This puts 60% of the US’s offshore sites out of reach. One solution is to mount the wind turbine on a […]
