Edison's discovery that current can travel through a vacuum didn't turn out to be very useful information until 1904. That's when a British scientist named John A. Fleming made a vacuum tube known today as a diode. Then the diode was known as a valve, because it forced current in the tube to travel exclusively in one direction.
