People are not using all the resources they have. Engines are running at half power. There is all this untapped potential out there. How to visualize this?
The engine room and a nice classical nautical engine control handle. You can use a standard PowerPoint "dougnut" chart (a pie chart but with a large hole in the middle) to create one.
Interesting, in the early days these handles would actually ring a bell in the engine room after which the people downstairs could adjust the power to the engine.
