Had the mill Ogden been success, Edison's reputation
as inventor would have been superceded his fame an
industrialist. The lab carried out experiments reheating
compressed air and using power source. His laboratory had developed
skills several commercial technologies which Edison hoped to
exploit. His efforts make the most the failure ore
milling illustrates the broad scope his commercial outlook
and the laboratory's strong engineering skills. After leaving Ogden
for good, Edison went back the laboratory and looked for
ways recouping his loses. Edison soon went into
the cement business for himself, using equipment designed in
his laboratory and experience gained materials handling at
Ogden. But just like Ogden, the giant
