But because only one in a million of the collisions actually produce fusion, the device is an inefficient generator of energy.

Seems to me that the hard part is done and some clever scientist/engineer could come up with a way to increase the efficiency.

Just the opposite is true in this case.

Creating minute amounts of fusion in the lab is fairly easy. For decades, the hard work has been to increase the efficiency and control the heat produced in order to use it to generate useful quantities of electricity.
