Any serious fusion proposal will breed tritium. Power to weight is going to be abysmal though.
Also slow acceleration is not the millenia long problem you're making it out to be, 0.01g will get you to 0.1c in under a century. Ion drives are largely limited by the weight of the power source even with current tech.
Any fusion reactor capable of working without prohibitively large radiatiors will have enough control over the plasma to just eject it for thrust directly. ISP will be your limit, not thrust.
Q-drive is a fairly compelling proposal compare to other options. Use some kind of magnetic solar sail to soar along the heliopause until you can make the trip in decades.
- samplatt 4y ago>0.01g will get you to 0.1c in under a century Okay, cool, but that's TWO centuries including the flip-&-burn halfway through. Also, an NSTAR thruster gives 0.000092 m/s2 for a single-ton payload. That'll take roughly 10,000 years to get to 0.1c, not 100 or 200 years.
