Next time you drop a bolt into your car’s engine and can’t find it no matter how hard you try, you’ll understand the difficulty of controlling small parts. Now imagine dropping that bolt into a 3 million dollar turbine generator! That bolt will decimate the blades inside the generator causing millions of dollars in damage, and millions more in outage costs.
You can see why it’s very important that small parts always remain in control. Something that costs a few pennies can really cost millions.
