How can I get a decent mass-ratio with a step rocket?
You would still have a terrible mass-ratio because of the shielding and I'm betting you couldn't convert one percent into thrust.
Auxiliary tanks for single-H were fitted around the Stone's middle, giving her a fat and sloppy appearance, but greatly improving her mass-ratio for the ordeal.
With contragravity, of course, terms like "escape-velocity" and "mass-ratio" were of purely antiquarian interest.
Suppose we make it a chemical fuel and a moon rocket and assume a mass-ratio of twenfy to one.
If you had a decent way to use atomic power, you might be able to hold your mass-ratio down to, let's say, one-to-one.
"It enables you to omit the first step-rocket stage, which is bigger than all the others put together and is terribly inefficient, as it has such a poor mass-ratio.
