As I was growing up, my parents always emphasized that we see in life what we train our sights upon. If we train our sights upon insults, negativity, injustices, or just ugliness in general, those things will dominate our thoughts and our lives. If, on the other hand, we train our sights on positive accomplishments, and on the good and the beautiful things that surround us, those things will dominate.
Earl Nightingale once famously said, "we become what we think about most of the time." His statement takes my parent's idea one step further by suggesting that what we train our sights upon tends to come back to us. It helps make
I hate to give up my age but I was a teenager during the Vietnam war era. My draft lottery number was 51. I would have been required to report for service but I had just started college and got a deferment. As things turned out, the war ended before my deferments ran out and I dodged the bullet, so to speak. But I had and lost a number of friends who served in Vietnam. Those who made it home were often wounded and almost always scarred in some way. At that time, I was too young and immature to fully recognize how much they sacrificed for the rest of us, but not so much that I couldn’t recognize the travesty of a nation that disrespected its veterans.
The nature of labor in our world is constantly changing but one thing remains constant - without laborers, we would have no highways, trains, planes or automobiles, electronic devices, buildings, furniture, food, clothing, computer software, tv programming, health care, and the list goes on and on. Everything we have to improve our quality of life, comes from the labor of hard-working and intelligent people.
Vapor Compressor vs. Absorption
Most of us are at least somewhat familiar with the basic concept of vapor compressor refrigeration. This process is typically used in refrigerators and freezers, and room and building air conditioning units. A refrigerant gas is compressed and pumped through a condenser circuit where it condenses into a liquid and releases heat in the process. The condenser generally consists of a set of coils that allow for efficient heat transfer aided by a fan that helps carry the heat away into the surrounding air. In larger commercial systems, the heat might be carried away through a water cooling system.
There is a form of “robustness” inherent in AC power generated by rotating electro-magnetic fields (spinning generators). Those magnetic fields are a form of very short-term power storage that can fluctuate in reaction to changing loads. This is one form of reactive power or VAR (Volts-Amps-Reactive). VAR provides a level of stability to the power and adds a component of muscle to the power which enhances its transportability across distances.
Sometimes it feels like we are drowning in data. This can be discouraging but there has been great progress recently in tools to help with this data.
When it comes to energy data, your bills can be a great source, but how do you make that data useful? And what if the bills don't tell you everything you want to know? This article discusses the challenges and offers some great advice.
The importance of balance comes up in many contexts these days. Behavioral professionals speak of work-life balance. Mechanical engineers employ counter balancing shafts in motorcycle engines to reduce vibration. Airlines carefully fill seats to assure that the airplane's balance point is preserved.
I love our country. I love all of the good things our country stands for, and I'm grateful that our founding fathers had the courage to stand up to King George III and demand our independence. The risk of being hanged for treason made their actions even more remarkable. I'm also grateful for their wisdom as they set up a form of government that was as revolutionary as the war they were fighting. It has served us pretty well over the years.
