it's not just the cost of the fuel haha and you realize how much work it takes to inspect a tangled knot of tubes and all the turbines? not to mention the actual refurbishment

solid rockets can be literally 3d printed and made with complete automation which makes them barely more expensive than the fuel itself vs hundreds of million of dollars plus the refurbishment and inspection


a cool idea is solid state liquid engines which use magneto hydro dynamics, ie circulating conductive fluids between

so you'd still need the plumbing and the tanks but you could replace the turbines with magnets although they would be a lot heavier and i think there are some cool things you can do with MHD that you cant do with conventional turbines but i still need to read through the whole paper
