Ep. 252 - Why Saying “Diesel” Now Feels Like Yelling “Mufasa” — Jim McDonald on Backup Power
from The QTS Experience · host Dave McCall
Somewhere along the way “diesel” turned into a dirty word. Jim McDonald’s spent 30 years on the generators that keep 911, hospitals, and your data alive — and he’s a little tired of playing the villain. We get into what’s real, what’s myth, and why he still thinks everybody wins.
