Solid fuel/liquid fuel

[Matthew]

Which weighs more, solid fuel or liquid fuel for the same amount of thrust?

[Spacedout]

don't liquids end up weighing about the same as solids
so if you ask me it doesn't really matter but if im worng tell me

Hi Spacedout! :D

Liquid and solid fuels are different. Liquid fuel uses liquid hydrogen and liquid oxygen for fuel. But solid fuel rockets use a different type of fuel.

I wish I could tell you but I can't.

Until the 'parafin thrusters' were designed, solid fuel rockets were most powerful (I believe they used MnO4, but I'm not 100% sure).

But, now that a proper way of using parafin has been discovered, I'm pretty sure it's the hottest burning fuel now.
