Tiny Minions Can Make Air into Stone
When you think of tiny minions, you probably think about movies or ants, but how about bacteria? Carbon dioxide (CO2) is of course one of biggest challenges to the climate today. Humans create millions of tons per year and natural processes far more. Plants and natural processes sequester almost all of it into more plants […]
Will Coffee Someday Power Your Car?
Hydrogen is probably the gold standard in “green” fuels, however producing it and storing it safely is a major challenge. Researchers at MIT came up with an interesting process that at least does not require storing the hydrogen. First, they realized that hydrogen could be produced by adding aluminum pellets to seawater. However, the pellets, […]
PE EXAM TIP – Have Only One Way to Work a Problem
There is a wealth of information out there on how to solve PE Exam problems. For any given class of problems, you can find many solution approaches. You may have even thought of additional, and quite valid, approaches on your own. However, seeking out a number of approaches has a troublesome downside. All you need […]
With DTC, Practice Makes Perfect
Poor time management during the exam. That is the most common reason our participants say kept them from passing the exam. With the clock ticking, especially on the CBT format exam, it’s easy to get thrown off your exam-day plan, waste time on difficult problems, realize the clock is running out, and panic. But it […]
A Concrete Foundation to Store Electricity
One of the biggest challenges with solar and wind is that they are intermittent sources of energy, requiring storage to make viable for a grid. Likewise, nuclear has trouble cycling down at night and responding to varying loads during the day. Imagine a building being able to store energy for use later. Franz-Josef Ulm at […]
FEATURED TESTIMONIAL – “DTC was 99% of what mattered to my preparation.”
“I passed the PE on my first try. I did the DTC course as well as a couple other prep exams. Those tests were ok for continued practice, but the DTC program was 99% of what mattered to my preparation. I would have been fine with just DTC. Dr. Tom’s program was exceptional considering the […]
The Race Is On
The title of a recent ASME SmartBrief article “Why the hare (rabbit) always beats the robot” really caught my attention. We normally think of robots as being much faster at doing things than living creatures, but it turns out this is not the case. Researchers at the University of Colorado at Boulder and at the […]

Making Gravity Our Friend
In a recent ASME SmartBrief an article caught my attention. The Chicago-based company Skidmore, Owings, and Merrill (SOM), who designed the Burj Khalifa tower in Dubai, UAE, the tallest tower in the world, is turning its attention to using gravity as the basis for storing energy. Energy from sources like wind and especially solar need […]
FEATURED TESTIMONIAL – “Dr Tom’s Course Is Absolutely Outstanding”
“My Dr. Tom review course was ABSOLUTELY OUTSTANDING. I HIGHLY RECOMMEND it to everyone! I learned there was definitely a methodology for taking the PE exam, and Dr. Tom and his team know exactly what it is. A person may know engineering well, but unless properly prepared on what to expect on the exam, how […]
