Imagine if we can put fusion reactors in thing that can move like planes and ships...

  Well, we don't have a single fusion reactor besides thermonuclear bomb.

    I think we might just barely be able to build a piston engine large enough to make use of that. It would have cylinders capable of swallowing container ships whole. You'd want at least 4 cylinders of course, maybe more. It'd be something like a trillion-liter engine. The emissions control device and the muffler would likewise be huge. The fuel injectors would need to toss the thermonuclear bombs clear of the piston and valves and cylinder walls, ensuring some distance between the fireball and anything that could be damaged. So yeah, there might be downsides, but I think this is actually a valid design for a fusion reactor. We really could do this.
