The very hot, diffuse plasma from a fusion rocket often provides a thrust that is too feeble to be practical, with an exhaust velocity that gives a ΔV larger than would be practically needed. http://www.orionsarm.com/eg-article/49398ddb0191d
I think this sentence should be rewritten. I think it means that the thrust is low because the propellant fraction is small. How about
