Bizarre to most people I suppose, or perhaps genius to others. It depends on how you approach and solve a problem. I do quite a bit of Renewable Energy work using Off-Grid Solar which is extremely inefficient. At the very best on paper is 66% and realistically less than 50% when put into application. So if you want 1 Kwh usable, means the panels have to generate 1.5 to 2 Kwh. So with a 4 Sun Hour would require say 1.5 Kwh / 4 Sun Hours = 375 watts to 500 watts of panels to give you 1 Kwh usable. The priority is different where you would not be concerned too much about efficiency.The units conversion factor is certainly 746 W/hp. What Sunking calculated and presented as "w/hp efficiency" was a combination of the inverse of efficiency and the units conversion factor, which I agree (as I suggested earlier) is bizarre.

So tell me which is easier and takes less fingers and toes to figure out. Teacher ask:

*We have a motor that develops 10 HP, is 74.6% efficient, and uses 1000 watts per HP. How much electrical power is required to run the motor?*

A Nerd would pull out a slide rule like he was taught, go to work pushing buttons using traditional percentage method to solve the problem, and finally figured it out about 5 to 10 seconds after I raised my hand and said "

__" Guess who got an A+ from the teacher.__
