I don't know, it seems to work for the car industry. Almost every new vehicle floats around the major shows as a 'concept' to gauge public reaction and perception before making it into production having taken onboard a large number of changes.
Almost every new vehicle floats arount as a concept, but at the same time almost every concept that floats around the major shows never makes to an actual production vehicle - because even if the people like it, they often are too impractical to make or too expensive for their target market&competition.
