Specific Impulse

I have created a spreadsheet that will be updated somewhat regularly to show the specific impulses of various fuel combinations.
I've just started but, I currently think that propellants need to be organized along several lines, solid/liquid, hybrid, mono/bi/tri-propellants.
Another consideration is production. If you are scooting around the solar system, you're not going to find a filling station so, some attention will need to be applied to the concept of producing fuel from whatever sources are available.
This will go in the field chemistry guide.
