chemical rockets is extremely wasteful on fuel and have a very hard time taking up alot of payload with out a very big rocket that uses even more fuel !!!!! if you look at a NASA rocket that ENTIRE thing is carrying liquid hydrogen and liquid nitrogen all so that a handful of people and a payload of less than a 5% of the mass of the entire rocket can get into space!!
Ion rockets or plasma rockets have low thrust .So as of right now, they could never lift anything from earth do to the low thrust .But what about nuclear or fusion ? Do they have enough thrust and can they take up more payload than now ?

Note I keep getting replies of safety reasons are why we do not use nuclear and that nuclear is generally frowned on.But I will like to know can nuclear or fusion take up more payload or are they not that much better than Chemical rockets.
I hear that nuclear or fusion can take up 5 times more payload than chemical rockets is that true.
What about laser propulsion?
NASA is lookingh into laser propulsion and it looks promising.If people would go to school than watch p or n they would talk that they know what they are talking that their ***.
Americans unbelievable.
