Bloodhounds aren't renowned for being fast. This remarkable Bloodhound will cover a standing mile in 3.5 seconds and break the 1000mph land speed record. When reading this remarkable story I was struck that it was a tale of near-perfect knowledge sharing and collaboration, as well as an engineering marvel. Listen to the audio clip of Yan Tiefenbrun, the MD of Castle talking about how he assembled the finest expertise from surprisingly diverse industries to develop completely new insights. They are not only building the fastest wheels, but a model for open-source knowledge sharing. If you face a daunting innovation challenge or knowledge-sharing problem, be inspired by this British cross-industry project.
