Also, Wilson has broken down the structure of graphite to the molecular scale. This allows the graphite molecules in the racquet to self-multiply and change shape. Effecting allowing the racquet to extend and expand on the fly. The energy to do so will come from the impact of the balls.
What's is old is new again....
The Bergstrom (sp?) Long String had a key that enabled you to "tune" your tension. I believe there was another racquet from years past which had the same type feature.
