Neighbor George, to your comment "So they can do all the math they learned in a class room, won't change a thing."
Actually math CAN ANSWER the "question asked" of how many watts are required to RUN a motor and actually math and engineering and physics CAN ANSWER the "question NOT asked" of what's required to START a motor, and I covered BOTH in my response. Having been an electrical engineer at the Century Electric Motor Company I can tell you from experience and education the math to RUN a motor may be less complicated then what it takes to START a motor. HOWEVER if you notice I told the poster the current required to START a motor may be 3 to 5 times what it takes to RUN a motor !!!!!!!!!!!!!
You're right, many lack the experience and/or education dealing with starting currents of a motor. I however do and try my best to explain it to the non electrical trained and experienced gents here.
You're also right, "the math wont change a thing" and that's true for the math to RUN a motor or the math to START a motor. Once calculated "it wont change" although physical wear and tear and friction and outside forces may change causing changes in the math.
Of course to each their own free choices, be it a Battery and Inverter orrrrrrrrrr a 12 VDC Compressor orrrrrrrrrrrr a Gas powered compressor. Each has advantages and disadvantages. Wouldn't it be a boring world if we all had to do things the same way or had to follow what one person chose.
Best wishes n God Bless neighbor, take care n stay safe

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
