There is never going to be a 100% improvement in 'normal' rockets - you cant gey any more energu out of a chemical reacrion. We are using all the energy that we can get out of the most powerfull fuels that exist. The only two ways to get 'sci-fi style rocket is either nuclear, or to beam energy to the rocket from outside with giant lasers.

Other ways are: 1. air launch, which boils down to using the O2 in the air rather than carrying it with you 2. mass driver, which needs to be in a vacuum 3. gravity slingshots But, yeah, we need a fusion drive.

  >2. mass driver, which needs to be in a vacuum Project HARP[0] disagrees. Launched a payload 110 miles (177km) into space using a 120 foot (36m) long cannon. This was in the 1960s. [0] https://en.wikipedia.org/wiki/Project_HARP https://en.wikipedia.org/wiki/Project_HARP
