Low Hanging Fruit – Meet Vortex Madness

By Energy Rant No Comments
This week, we are taking a trip down easy street to explore what I called three years ago in DOE Pumping Standards a nauseating term, “low hanging fruit.” I love charts like the one below. Where can you find stuff like that? Well, the source vanished, except that I posted it in the Rant, it lives!Because of associated nausea and our love of acronyms, let’s call it LHF. On that note, it looks like left-handed fingering (think guitar playing) dominates the market for the LHF acronym. What does the idiom LHF mean? Lighting and Motors Lighting and motors are the…
