  • $\begingroup$ Very dense - it serves some purpose? Regular density is not acceptable for some reason? Which reason it is? - it may be important for an answer. Generally looks workable, lid helps for convinience but not a necessity. $\endgroup$

  • $\begingroup$ @MolbOrg A funnel that is designed to hold a certain mass of dust will be smaller and lighter if the dust takes up less volume (i.e. is denser) $\endgroup$

  • $\begingroup$ Eh? Lol, okay. You can have no funnel if you store your reactive mass properly in blocks, and make the dust when the fuel is actually used, that if you care that much about mass of funnel. It itself can be made of that solid, to be crushed for dust, etc. You also underestimate (maybe) the amount of reactive mass you need for constant acceleration for significant time. But it is up to you, but I would recomend to make some simple visualisation of your design(paint picture) and figure out some numbers and add to this q or make another one for purpose to refine design, looks u may need it. $\endgroup$

  • $\begingroup$ What you have missed is to explain why would the propellant propel the ship insted of just propelling itself out of the funnel. $\endgroup$
