In fact, it's the least important thing once you're in orbit. There are rockets that thrust for weeks and only get a few m/s faster. The real important thing is how much thrust you get for how much fuel - e.g. a kilogram of this fuel may accelerate you by 1 m/s but a kilogram of that fuel may accelerate you by 2 m/s. So the second fuel is better.
Efficiency is an interesting thing. There is more than one kind of efficiency - you just showed the TWR or ISP for rocket drives, which is very hard to tell anyway, and the energy efficiency, however you try to negate it with the rentability showing that the fuel is hard to handle. Indeed, it is, but I only showed how VRSG stores more energy per particle than COAL does. Which still remains true. As for the rocket drives... High thrust is not the most important thing in them.
it's still more efficient
who needs a vrsg fuel if its only a bit better then coal, but more dangerous? just use coal kid, stuff dies less with it
you can put it only on diamond and it is eating void and clone
com20027. virus gas is eating pump. but you an use airwall
Yes. VRSG is not an cool fuel because you can place coal in anything, but virus can be placed ONLY in diamond.
how about using pump to make rocket with vrsg?
