The small insulated cup's power was actually far greater than my armor-piercing cannon with 150 damage. Its damage radius exceeded twenty meters!
Comparable to a 122mm heavy grenade cannon!
Ding Yi nodded, and naturally said:
"That's for sure, only hydrogen could have such a high energy density. You must know that the energy density of liquid hydrogen is more than three times that of gasoline in the same unit. Even for rocket launches, the engine uses liquid oxygen and liquid hydrogen as fuel, which also has the highest specific impulse among the three mainstream methods, representing the most efficiency."
"But as you just mentioned, even if a whole fuel tank is filled with liquid hydrogen, it can't sustain high-intensity combustion for more than ten hours, let alone it needs half of the space for storing liquid oxygen to aid combustion."
"Otherwise, where would the sixth underground level get so much oxygen to serve as the oxidant for hydrogen combustion?"
