As for using boron and expecting nuclear things to happen, there is something similar that is already a thing. It's called boron-neutron capture therapy. It involves a chemotherapy medication that is not yet active. It incorporates boron in its structure, but is not actually active until the boron captures a neutron and transmutes into carbon. The idea is to inject the medication then aim a neutron beam at the tumor. The substance is transmuted at the beam and becomes active - but only there.

So transmuting boron really is a thing. Whether it captures a proton as easily as it captures a neutron is another question.

The article didn't seem to have much more info than TFS so I'm guessing here, but in general, you may not need to generate net power for fusion to be useful for rocket thrust.

There's plenty of solar power available in space (at least near the inner planets), and as the Farnsworth fusor showed decades ago, it's not hard to generate fusion reactions if you don't expect positive energy output. For some space missions, propellant mass is very important, and getting the highest velocity exhaust is the goal. Using solar energy to induce fusion reactions could be one way to do this. Of course, like most ion drives, this would be very low thrust over long time spans.

For the number of articles I have read about how "self-driving cars are never going to happen," including such details as their total inability to make an unprotected left turn, Google seem to be opening a lot of (presumably functional) services.
