It says:
"Chemical combustion: ~ a few MJ/kg
• Solid Propellants: ~ 5 MJ/kg
• Liquid Propellants: ~ 1 MJ/kg"
Which doesn't look right. My son (a rocketry enthusiast) tells me:
"Liquid engines have energy density between 12 and 20MJ/kg.
Apparently they just left off the 0 and likely meant to put 10MJ/kg"
- hermitcrab 3y agoI got a reply back from the author of the slides: "Your son is correct, that is a typo - it should be 10's of MJ/kg for liquid rocket propellants - thanks for the catch! Thanks too for the heads up re the discussion on antimatter, it is a fascinating topic and great to see there is interest in the community!"
