She holds my eyes for a moment. And then she actually smiles. ‘What do you need?’ ‘Root access to this body. I know what it can do. I need computing power, way more than baseline.’ Mieli takes a deep breath. ‘All right.

It is found that I sp is strongly dependent upon the temperature (T) and average molecular weight (M) of the gases. Specifically, I sp is proportional to the square-root of the ratio of T/M. Thus, increasing the temperature or decreasing the average molecular weight of the gases increases I sp . Since the maximum temperature is limited by the material of the engine, the usual approach is to attempt the reduction of M by using fuels rich in hydrogen (since hydrogen has a low molecular...
