Bob Luddy is the founder of the Thales Academy schools here in Wake County and he sounds like an amazing man. Here's one tidbit:
In 2013, the town of Rolesville, North Carolina got a new public high school that cost $76 million. A year later, Thales opened a $9 million high school two-and-a-half miles away. Though much smaller, when divided by the number of students each building can accommodate, the Thales school cost half as much.
In addition to the video in the piece linked above, here's another worthwhile look at Thales (7.5 minute video).
