Amitabh Saran, the chief executive of Altigreen Propulsion Labs, and his team had a unique problem. They had to remove a film of deposit off their thin laminations. Every possible idea was thought of—scrubbing with a rag, washing, using a rust remover.
Engineering head John Bangura did not endorse any of these. He wanted a chemical into which the laminations could be dipped to remove the stains. Bangura knew such a thing existed in the United States. The team was in a fix until a vendor referred someone who could possibly supply such a chemical. Phone calls were made and the chemical was promised. The team waited with bated breath.
