Centrifugal pumps move water through most of our industrial and municipal water supplies. Because they are so widely used to process our water, centrifugal pumps consume 6% of all US electricity every year. These pumps are often used inefficiently because they have variable levels of flow throughout the day.

Hilary Johnson invented a centrifugal pump with adaptive geometry which changes the pump's volume as it processes water to match the flow rate of the system, significantly improving efficiency, operating range, and reliability.
